Topic 1: Classification, examination and diagnosis of dental trauma injuries

Traumatic dental injuries are potentially very complex. Hence, it is essential to have a thorough understanding of the various injuries that can occur so appropriate management can be undertaken. The first stage in managing all traumatic dental injuries (TDI’s) is to obtain a thorough history of how, when, where and why the injury occurred. This will facilitate the subsequent clinical examination which must be comprehensive and include all tests and adequate radiographs, photographs, etc. Once all the information has been gathered, then the appropriate diagnoses can be made. In order to diagnose TDI’s effectively and consistently, it is important to know and understand the classification of such injuries. The most widely used classification is the one developed by Andreasen and adopted by the World Health Organisation. There is also a new system that can be used to more thoroughly document TDI’s and this will be outlined.

Topic 2: Root fractures / infection and inflammatory resorption

Part A – Transverse Root Fractures (commonly called horizontal root fractures) are a complex injury, but they usually require little in the way of invasive or irreversible treatment. Unfortunately, this type of injury appears to be poorly understood by many dentists and this has resulted in many teeth with such fractures being poorly managed in the past. This lecture will specifically discuss this type of injury and how it should be managed. A variation of the classification of root fractures will be explained and this will help dentists in the management of these fractures. The long-term prognosis of sub-crestal coronal third root fractures, middle third root fractures and apical third root fractures is usually very good, if managed appropriately and conservatively. However, supra-crestal coronal third root fractures have a poorer prognosis with respect to the pulp and restoration of the tooth due to the location of the fracture, which is similar to a complicated crown:root fracture. Management of these fractures poses dilemmas for the dentist and some guidelines will be presented to help the decision-making when a supra-crestal coronal third root fracture is present.
Part B – External inflammatory resorption is a complex topic but one that has been well researched so the dental profession now has a good understanding of how it occurs and when it occurs. This allows us to predict the injuries that are likely to result in this type of resorption so we can then focus our management on preventing its occurrence. However, sometimes, external inflammatory resorption will already be present by the time a patient presents for treatment. Hence, interceptive treatment will be needed in order to arrest the resorptive process and to stimulate healing and repair of the lost hard dental tissues and periodontal ligament. In this lecture, detailed protocols for both the preventive and interceptive management of external inflammatory resorption will be outlined.

Topic 3: Dilemmas in case selection: Which teeth should be endodontically treated?

There are many factors that affect the outcome of Endodontic treatment and the longevity of teeth following treatment. Most Endodontists, dentists and research studies have focussed on the technical aspects of treatment or the presence of periapical radiolucencies and their effects on treatment outcome. Little attention has been paid to case selection. This presentation will explore this issue and will provide guidelines on how to assess and select teeth that likely have a good prognosis, and what criteria to use to reject teeth that have a poor prognosis. Whilst case selection affects treatment outcome to some extent, it has a much greater effect on the longevity of the tooth following Endodontic treatment with the most important factor being whether the tooth is suitable for further restoration. This issue has not been adequately addressed in the literature yet it is very important and it will be explored in detail in this lecture.

Topic 1: Tooth replacement in the anterior maxilla: orthodontic space closure, prosthetic options, implants or autotransplantation

The lecture will present strategies how to manage situations where teeth have been lost in the anterior region of the maxilla after trauma in young growing patients. Different treatment alternatives must be considered such as prosthetic treatment, orthodontic space closure and autotransplantation of another tooth to the anterior region. Implant treatment is contraindicated in the young growing patient because it interferes with growth and the lecture will present how to assess when implants at earliest can be placed in an adolescent patient. The various alternatives when treating a patient with tooth loss in the anterior region must always be related to the growth status of the individual patient and the aim of the lecture is to present strategies for the choice of treatment in each individual situation. The importance of timing and an inter-disciplinary approach to these cases will be emphasized.

Topic 2: Tooth avulsion and replantation

The most serious dental injury is avulsion (exarticulation) of permanent teeth. This injury is most often seen in young growing patients, which presents special problems when it comes to treatment. The most important phase for the prognosis is the emergency management. An avulsed tooth can be replanted and successfully heal if properly managed immediately after the injury. Injuries to the periodontal membrane and the pulp will decrease the possibility for a successful healing. Information to the public such as children, parents and teachers who may be present at the place of accident is therefore important. Furthermore, clinicians must understand the principles of tissue injury and healing of tissues after replantation to be able to early diagnose and correctly manage potential later complications such as root resorption, ankylosis and infraposition, which is especially important in growing children. The lecture will address the important aspects of tooth avulsion and replantation such as correct first aid at the place of accident and emergency treatment in the dental clinic. The lecture will also present principles of healing, diagnosis and treatment of potential complications based on recent evidence from scientific literature. Results from recent long term clinical follow up studies of replanted teeth will be presented.

Topic 3: Tooth ankylosis, replacement resorption and bone preservation

Root resorption is sometimes seen after traumatic dental injuries and autotransplantation. While infection related root resorption today can be prevented or treated, ankylosis is the most serious complication for the tooth resulting in progressive replacement resorption of the root by bone and eventually causing loss of the tooth. Moreover, inhibition of growth and development of the alveolar process is also seen in young growing patients following ankylosis. The lecture will give a complete overview aiming at understanding the development, progression, and management of ankylosis based on in vivo- and clinical studies and an overview of the literature. An overview of various less successful methods to manage ankylosis will be given and the method of choice today, decoronation, will be presented. The recent shift in paradigm from “save the tooth” to “preserve the bone” will be presented.

The Modified Tweed technique represents a refined evolution of classical orthodontic biomechanics, integrating scientific precision with individualized force control to address the limitations of modern preadjusted appliance systems. While straight-wire and MEAW (Multiloop Edgewise Archwire) techniques have advanced clinical efficiency, they often compromise true biomechanical customization—relying heavily on bracket prescriptions or complex wire loops that may produce unwanted side effects.
This lecture revisits the biomechanical philosophy of the Modified Tweed approach, emphasizing torque expression, anchorage control, and three-dimensional force management. Through comparative analyses, it demonstrates how Modified Tweed mechanics provide greater control of incisor inclination, vertical dimension, and facial aesthetics, while minimizing occlusal plane distortion and root resorption. Unlike preadjusted straight-wire systems, the Modified Tweed technique allows for personalized wire geometry and precise moment-to-force calibration, leading to more predictable tooth movement and post-treatment stability.
The session will integrate theoretical concepts with clinical case demonstrations, highlighting efficiency gains, reduced wire fatigue, and superior long-term outcomes. By blending classical biomechanical principles with contemporary materials and digital planning, the Modified Tweed philosophy remains highly relevant in achieving functional harmony, esthetic balance, and biomechanical excellence in modern orthodontics.

Topic 1: 3D Direct Printed Appliances: A new perspective for multiple treatment applications

The methods for producing dental appliances are rapidly evolving with the introduction of advanced, affordable 3D printing systems designed for clinical environments. These new printers make it possible to fabricate a wide range of appliances, including orthodontic 3D printed aligners, TMJ splints, sleep apnea devices, growth modification and various removable appliances, directly in the dental office.
This technological shift represents a major step toward a fully digital workflow, enabling the predictable creation of appliances generated from simulation software. Directly printed appliances have the potential to be more accurate, faster to produce, and more cost-effective than conventionally fabricated laboratory appliances.
In this presentation, we will review the core technologies and materials that make this transformation possible, highlighting how digital design and additive manufacturing are reshaping clinical dentistry. The discussion will primarily focus on orthodontic aligners and sleep apnea appliances, the first clinical applications of this emerging technology, while outlining the expanding possibilities for other custom-printed devices in the near future.

Topic 2: Artificial or Decision Intelligence? What does the orthodontist want and need?

Artificial Intelligence is the new buzz word in the 21st century. Everything around you seem to be controlled by AI. AI is almost thought as the future replacement for many professions, orthodontics included. However, AI is indeed a very powerful data management system controlled by algorithms created by humans. Its goals are to analyze data and predict outcomes using mathematical models. As helpful as these concepts are, the human element of judgement, intuition, psychosocial approach of our patients is absent from these predictions.
Combining clinical judgment with AI driven predictions promises to offer the clinician a broader perspective to further improve the predictability of individualized orthodontic treatments. Decision Intelligence (DI) is the combination of artificial and human intelligence. DI is being increasingly applied in the field of medicine as it offers the power of mathematical reasoning with the human element added to provide the practitioner with a more compelling diagnosis and treatment planning.This lecture will explore how incorporating DI in a busy orthodontic practice can enhance the outcome of their treatments while retaining full control of the final decision.

Lasers have been used in the orofacial region for over five decades; challenges remain in their effective application in dental practice. Many dental practitioners still view lasers as alternative devices rather than integral to clinical approaches. This keynote highlights the need for an accurate perception of orofacial laserology, covering key areas such as laser physics, tissue interaction, and safety. It categorizes laser therapies into high-intensity, selective, and low-intensity and emphasizes practical decision-making. Additionally, it underscores the importance of ongoing education in the Asia–Pacific region, where varied clinical environments and access to training create both challenges and opportunities for sustainable learning.

Predictable esthetics that endure biologically is the new standard of care. This keynote connects digital planning with peri-coronal and peri-implant tissue health to deliver long-term, patient-centered outcomes. We will map a “digital-to-biologic” workflow—diagnostics (DSD/AI simulations), prosthetically guided tooth movement or site development, and minimally invasive restorative execution—showing how each decision (emergence profile, margin position, surface topography, cleansability) influences soft-tissue stability, biofilm behavior, and maintenance. Indian clinical cases and multi-unit rehabilitations illustrate how digital wax-ups, AI-assisted previews, and risk-stratified material choices (ceramics, hybrids) can reduce chair time while improving esthetics, function, and patient-reported quality of life. Evidence on digital versus conventional steps, occlusal design for parafunction, and soft-tissue engineering around teeth and implants (collagen fiber orientation, transmucosal contouring) will be translated into chairside protocols. Delegates leave with checklists, decision trees, and communication assets that raise acceptance and reduce remakes—without compromising biology. The session closes with maintenance strategies and metrics for success that blend clinical indices with PROs, building a durable “smile-for-life” practice model.

Learning Outcomes
1. Identify prosthetic design variables (emergence, margins, texture) that affect periodontal/peri-implant stability.
2. Compare digital vs. conventional steps for efficiency, accuracy, and outcome predictability.
3. Apply AI/DSD to increase case acceptance and esthetic precision in daily practice.
4. Design minimally invasive preparations and transmucosal contours that enhance soft-tissue health.
5. Evaluate success using clinical indices and patient-reported outcomes; implement maintenance pathways to reduce biological and technical complications

Distraction Osteogenesis (DO) is a transformative biological technique in oral and maxillofacial surgery that enables simultaneous regeneration of bone and soft tissues through gradual, controlled distraction. This presentation, based on over 25 years of surgical experience, highlights the wide-ranging clinical applications of DO in dental and maxillofacial practice. At the minor end, alveolar distraction allows predictable ridge augmentation, arch widening, and height gain for implant placement. In orthodontic and orthognathic contexts, DO facilitates controlled jaw advancement and transverse expansion, improving occlusion and facial balance. Complex reconstructions—such as facial asymmetry, syndromic deformities, post-traumatic or oncologic defects, and cleft-related deficiencies—benefit greatly from DO’s capacity to regenerate both bone and soft tissue.
Proper planning, vector control, and activation protocols yield stable, vascularized bone suitable for long-term function. DO represents a paradigm shift—from replacing to regenerating bone—offering general practitioners a biologically sound approach to interdisciplinary and comprehensive patient care.
Learning Objectives:
– Explain the biological basis and stages of Distraction Osteogenesis.
– Identify indications and applications of DO in dental and maxillofacial surgery.
– Describe planning principles, vector control, and activation protocols.
– Discuss the role of DO in managing complex craniofacial deformities.
– Integrate DO concepts into general and interdisciplinary dental practice.

Dental caries and erosion are pressing oral health issues that significantly impact individual well-being, resulting in financial burdens, discomfort, functional limitations, and overall diminished quality of life. The advent of Minimal Intervention (MI) dentistry has revolutionized caries management, making the pursuit of lifelong oral health a tangible objective. This transformative approach is reinforced by key policy statements from the FDI published in 2002, 2012, and 2013.
MI promotes a patient-centered treatment model that emphasizes minimally invasive and biomimetic restorative techniques, focusing on the preservation of tooth structure and vitality. Central to this framework is the “”Saving Our Sixes”” strategy, which highlights the essential role of first permanent molars (FPMs) in maintaining lifelong oral function. This strategy advocates for protective measures beginning at the eruption phase, such as surface protection and smooth surface sealants during the mixed dentition stage. When FPMs require fillings, conservation of marginal and transversal ridges is prioritized to maintain structural integrity, and indirect partial coverage restorations are suggested to optimize tooth structure retention.

The continued development of adhesive technologies, material science and clinical protocols has allowed the provision of conservative and durable direct and indirect restorations to address the myriad of complex clinical presentations, including the “sixes” commonly encountered in the general dental practice today. In addition, these modalities of treatment also fulfil the ever increasing patient demands for aesthetics.

The evolvement and the increasing sophistication of digital technologies, from digital planning and 3D printing, has also allowed the simplification of protocols in providing such minimal intervention restorative treatments.

By implementing the “”Saving Our Sixes”” approach, dental professionals can greatly enhance the long-term oral health of their patients, ultimately improving quality of life across diverse populations. This dynamic symposium will feature esteemed speakers, Professor Hien Ngo and Dr. Anthony Mak, who will share practical strategies and insights that practitioners can readily apply in their clinics. Join us to explore effective techniques for safeguarding oral health for future generations.

This lecture will explore the mandibular treatment responses that can be achieved without surgical intervention, highlighting how orthodontic treatment contributes not only to dental alignment but also to facial esthetics.
First, various types of mandibular treatment outcomes will be introduced, focusing on mandibular repositioning. These include three types of rotational movements—pitch, roll, and yaw—and three translational movements—forward/backward, upward/downward, and lateral.
Clockwise mandibular rotation in Class III patients and counterclockwise rotation in Class II patients is classified as pitch rotation. Other mandibular responses are categorized as “mandibular jumps,” which serve to correct occlusion and enhance facial esthetics.
The second part of the lecture will discuss the mechanisms behind mandibular jumps and the possible dental interferences that may influence them.
Learning objectives:
– What are the different treatment results of mandible?
– Types of mandibular repositioning.
– How could the mandible jump during orthodontic treatment?
– Deprogramming the occlusion.

Some of the most difficult cases to treat to a predictable, good outcome are Class III malocclusion non-growing patients. The famous professor from North Carolina, Dr William Proffit coined the term “camouflage” many years ago to describe non-surgical treatment that essentially moves the dentition to hide the underlying skeletal problem. This can be done in a number of ways in Class III cases in which the skeletal problem is a combination of maxillary deficiency and mandibular prognathism. Correct diagnosis is the key and a fundamental knowledge of facial growth and recognition of certain growth patterns are crucial in deciding what mechanics will work. Will the case need extractions? Skeletal anchorage? Functional appliances? The clinical methods and tips will be illustrated with complete case records including case selection, appliance selection, and finishing for Class III malocclusion successful camouflage treatment.
Learning objectives:
– Diagnosis and case selection Class III non-growing patients for non-surgical camouflage.
– Basic biomechanics using fixed appliances for successful outcomes.
– Problems to watch out for in finishing.
– Underlying skeletal problem of bimaxillary Class III.

As the autogenous bone graft still remains “Gold Standard” in implant dentistry, several bone graft substitutes have been developed to come up with “God Standard” in terms of components and function such as osteoinduction, osteoconduction, and osteogenesis.
Based on highly ranked evidence-based literature and qualified certification, I will introduce the bone graft technique using Hu-BT on socket preservation (ridge preservation), ridge augmentation, guided bone regeneration, ridge split, and sinus augmentation as Simplest Bone Graft Technique.
Since the introduction of tooth-derived bone graft substitute in 2015 (Hu-BT, Korea Tooth Bank, Seoul, Korea), clinical safety and efficacy has been approved by KFDA and KAHW as similar to the “Gold Standard” in component and function.
In addition, I will provide clinical studies and long-term results on whether we achieve the final goal of bone graft in dental implant as the “Evidence-Proof” of “Successful Implant”.
Learning objectives:
– Understand the principles and step-by-step procedure of Guided Bone Regeneration (GBR) in implant dentistry.
– Master the clinical application of Hu-BT in various GBR cases.

Immediate implant placement in extraction sockets with infection has traditionally been considered contraindicated. However, contemporary evidence suggests predictable outcomes when careful case selection and meticulous infection control are ensured. This presentation reviews indications and contraindications, minimally traumatic extraction, thorough debridement and socket decontamination, and prosthetically driven 3D implant positioning to achieve primary stability in healthy bone. Strategies for managing jumping gaps and bony defects with simultaneous grafting, as well as soft-tissue management to minimize esthetic complications, will be emphasized. Key risk factors and preventive measures for early complications-residual infection, crestal bone loss, and mucosal recession-will be discussed, integrating current literature with relevant consensus recommendations. A practical clinical decision-making algorithm and step-by-step protocol will be proposed to help clinicians optimize outcomes when considering immediate implants in previously infected sites.
Learning objectives:
– Evaluate the current evidence regarding immediate implant placement in infected extraction sockets.
– Identify clinical indications and contraindications for immediate implants in the presence of periapical or periodontal infection.
– Apply a step-by-step clinical protocol focusing on infection control, primary stability, and 3D implant positioning.

Complex malocclusions – such as skeletal discrepancies and cases requiring extensive root movement – remain a significant clinical challenge in orthodontics. With advancements in the understanding of clear aligner biomechanics, many of these demanding cases can now be managed effectively using clear aligner therapy. In particular, the selective use of Temporary Anchorage Devices (TADs) has expanded clinical possibilities by providing superior anchorage control.
This presentation discusses strategies to optimize force delivery, enhance treatment predictability, and minimize unwanted tooth movements and refinement cycles in clear aligner therapy. Through representative complex cases, we outline practical protocols that integrate digital treatment planning with targeted TAD application. These examples demonstrate how TAD‑supported aligner mechanics can improve treatment efficiency and clinical outcomes across a wide range of malocclusion types.

IODs and hybrid bridges have been treatment options for complete and partial edentulous patients who have atrophic ridges and/or cannot tolerate conventional dentures. The prevalence of Implant Overdentures (IODs) and hybrid dentures still remains unknown however the benefits of hybrid bridges and IODs such as providing retention, support and stability have been discussed in a number of studies. While hybrid bridges and IODs are more comfortable for denture wearers, they are also more expensive, more technical demanding and higher maintenance cost compared to conventional dentures. This presentation aims to analyse advantages and disadvantages of available IOD types, the number of implants to be used, type of abutments. Complications and failure modes will also be analysed to helps clinicians to choose suitable IOD types for their patients. The installation techniques will be demonstrated and some repair technique will be illustrated.

The use of lasers in dentistry has transformed many clinical procedures by offering improved precision, minimal invasiveness, and faster healing. However, with these advantages comes the responsibility of ensuring proper laser safety, understanding laser classification, and recognizing potential hazards. Laser classification is established according to the potential biological risk posed to the eyes and skin. Based on international safety standards (IEC and ANSI), lasers are divided into four primary classes. Therefore, laser safety and prevention are critical in every clinical setting. Laser warning signs should be clearly displayed, and only trained personnel should handle the equipment.
Learning objective:
Describe the principles of laser.

Orthodontic treatment in patients with reduced periodontium represents a clinical challenge that requires thorough understanding of periodontal biology and careful biomechanical control. This presentation aims to review fundamental principles of orthodontic management in patients with compromised periodontal support based on current literature, and to share clinical experience through representative case reports. Key topics include comprehensive periodontal assessment prior to orthodontic treatment, selection of appropriate orthodontic mechanics, and treatment strategies, interdisciplinary periodontal–orthodontic collaboration, and monitoring of periodontal response throughout treatment. The presentation emphasizes the importance of individualized treatment planning, close periodontal supervision in achieving stable orthodontic outcomes while ensuring periodontal safety.
Learning objective:
Suitable indications for non-extraction orthodontic methods.

Orofacial dysfunctions (OMDs) in childhood—mouth-open rest posture, mouth breathing, weak chewing/swallowing, and speech motor issues—are common and shape craniofacial growth and overall health. Disrupted nasal airflow and low tongue posture alter muscle tone and growth vectors, predisposing to maxillary constriction, vertical facial patterns, malocclusion, and narrower upper airways. Downstream effects include sleep-disordered breathing with behavioral and attentional problems, blood-pressure changes, enuresis, reduced oral-health–related quality of life, and functional deficits such as poor mastication, tongue-thrust swallow, drooling, and articulation errors. High-yield red flags: habitual mouth breathing or snoring, forward-head posture, high narrow palate/posterior crossbite, persistent drooling beyond three years, texture aversion/prolonged mealtimes, limited tongue mobility, and persistent speech sound errors. Management should treat structure and function together—address rhinitis/adenoid-tonsillar disease, expand constricted arches when indicated, and provide speech/oral-myofunctional therapy. A proactive, multidisciplinary approach can improve growth, sleep, behavior, and long-term dentofacial stability despite variable short-term cognitive gains.
Learning objectives:
To synthesize current evidence on:
– Mechanistic pathways linking OMDs with craniofacial, airway, neuromuscular and neurobehavioral outcomes.
– Clinical “red flags” enabling early identification.
– Implications for multidisciplinary management.

MEAW (Multi-loop Edgewise Arch-Wire) is an orthodontic technique developed in 1967 by the late Professor Kim Young-Ho, originally to correct open bite malocclusion. Characterized by L-loops between adjacent teeth, MEAW is pronounced “Myo,” derived from a Chinese character meaning “magic technique.”
Although many orthodontists recognize MEAW mainly as an effective corrective method used in finishing stages or for open bite and Class III cases, its core concept lies in individualized orthodontic treatment, with emphasis on accurate diagnosis rather than the appliance itself.
MEAW can be summarized in three principles: individualized treatment based on skeletal and dental analysis; correction of malocclusion through occlusal plane control, applicable to all malocclusion types; and the ability to achieve three-dimensional tooth movement. Overall, MEAW aims to individualize, standardize, and simplify orthodontic treatment strategies.
Learning objectives:
– Understand the fundamental concept and historical background of MEAW orthodontics.
– Explain the philosophy of individualized orthodontic treatment emphasized in MEAW.
– Identify the role of occlusal plane control in managing various types of malocclusion using MEAW.
– Describe how MEAW enables three-dimensional tooth movement for precise orthodontic correction.
– Compare MEAW orthodontics with conventional orthodontic approaches in malocclusion treatment.

In contemporary implant dentistry, success is more than osseointegration—patients expect stable periimplant health, natural esthetics, and long-term tissue harmony. Perio– Implant Microsurgeryintegrates microscope-guided precision with hard- and soft-tissue regeneration to create a stable biologic foundation for implant restorations. Magnification enables minimally traumatic incision design, papilla preservation, tension-free closure, and high-fidelity suturing that support wound stability and predictable healing. Within the same workflow, targeted grafting—contour augmentation, ridge preservation, and connective tissue grafting—optimizes bone volume, tissue thickness, and emergence profile development. This lecture presents practical, reproducible protocols that combine microsurgical execution with regenerative strategies to improve healing comfort, esthetics, and long-term stability.
