Orthodontics is a treatment that changes the entire occlusion. Changing the occlusion will risk causing occlusal and temporomandibular joint problems. Orthodontic patients may have a healthy temporomandibular joint or a temporomandibular joint disorders acompany. The temporomandibular joint disorder may worsen after orthodontic treatment if the principles of restoring optimal functional occlusion are not followed. Orthodontic treatment can also be applied to treat temporomandibular joint disorders and in this case, it may be necessary to change the position of the condyle before orthodontic treatment, to ensure the reestablishment and stabilization of the optimal condyle position.

Ensuring respect for occlusal references is the most important principle in orthodontic treatment, especially in patients with temporomandibular joint disorders.

In the late of 19th century, it was discovered that Xylitol exists in nature. German Professor Emil Fischer, a Nobel Prize winner in chemistry, was the first to extract xylitol from beech trees. Later, in the 1960s, xylitol began to be produced industrially in Finland, and it became clear that xylitol has a positive effect on oral health. Turku Sugar Studies published in 1975 revealed that chewing xylitol gum after meals was as effective in preventing of caries as replacing all sugar in the diet with xylitol chewing xylitol gum after meals.

In 1986, a clinical trial of xylitol chewing gum was conducted in Ylivieska, Finland, on 11-12 year old children, and xylitol intake reduced the incidence of caries by 30-80%. Furthermore, in 1996, it was revealed that teeth that erupted during or after intake of xylitol had a long-term effect of preventing the onset of caries. In 2000, a field study of schoolchildren in Estonia reported that there was no difference in the effect of xylitol on caries prevention whether it was ingested as chewing gum or candy. In 2013, it was reported that mothers’ use of xylitol chewing gum prevent the caries occurrence in their children. Many studies have been done using xylitol, and several systematic reviews have been reported. From these studies and reviews that habitual intake of approximately 5 g of xylitol per day significantly reduces the incidence of dental caries.

In the presentation, I would like to introduce xylitol research conducted on children and discuss the caries-inhibiting effect of xylitol intake.

Conventional orthodontic treatment is conducted by combined use of bracket and wire. Apart from the main advantages of the brackets in three-dimensional control, inherent bracket-wire play may cause unwanted tooth movement within the slot commonly called as round-tripping. Unwanted movement, even in small amount, may be detrimental in serious pathologic situation such as periodontal loss, root resorption and temporomandibular joint disease, as well as significant relapse, where extremely precise tooth movement is indicated. In this scenario, a specific brace that eliminates the possible play is crucial.

In this presentation, recent advances in the bracket-free segmental or total arch movement using force-driven approach in various critical cases will be explained and demonstrated. The essential component includes ribbon arch with various actions in three dimensions, miniscrews and the adequate composite for direct bonding. Latest introduction of the flowable composite with optimal flow would be suitable for this approach with high clinical efficiency. Myofunctional therapy using specific flow is also possible without the need for laboratory procedure. Relevant clinical cases with three-dimensional occlusal aberrations.

To establish a physiologic and functional occlusion, we must consider the principles of adaptation and compensation, make a precise diagnosis (strategy) based on the concept of malocclusion and a well-defined treatment plan (tactics), and execute the tactics for achieving proper mandibular position, occlusal vertical dimension, occlusal plane inclination, occlusal guidance of each tooth, and stress management.

Orthodontic appliances will not produce effective results if they are used solely as gears or gadgets to move teeth. Achieving normal occlusion for individuals requires mechanics with a treatment system based on proper diagnosis and treatment planning. This time, I would like to introduce my technique for treating malocclusion with TMJ dysfunction utilizing the GEAW system.

Implant dentistry has evolved toward minimally invasive protocols that prioritize surgical precision, reduced trauma, and improved patient outcomes. This presentation compares two approaches: digital surgical guides and the GuruGuide—a refined freehand method grounded in clinical expertise. It begins by outlining the rationale for guided implant placement, especially in complex or beginner cases where accuracy is critical. Key terminology related to surgical guides is introduced to create a shared understanding. Clinical indications for guided surgery are reviewed, including cases with limited bone, proximity to vital anatomy, esthetic zone needs, and full-arch rehabilitation. Applications span single-tooth, multi-unit, narrow ridge, All-on-X, and overdenture cases. Digital guides provide accuracy through prosthetically driven, pre-planned workflows but have limitations in flexibility and cost. In contrast, the GuruGuide emphasizes real-time decision-making, tactile sensitivity, and anatomical awareness, favoring skilled clinicians in suitable cases. This comparative analysis offers practical insights into selecting between guided and freehand techniques. It helps clinicians decide when each method best supports a minimally invasive, predictable, and prosthetically optimal outcome tailored to individual clinical scenarios.
Objectives:
– Update clinical indications and techniques for applying digital surgical guidesin minimally invasive implant.
– Compare and appropriately select between Digital Guide and GuruGuide techniques in clinical implant practice.

This presentation explores the comprehensive management of maxillectomy defects, focusing on the progression from immediate to definitive obturators. Maxillectomy, often necessary for the removal of malignant or benign tumors, results in complex maxillary defects that impair function and esthetics. Immediate obturators are fabricated and inserted at the time of surgery to provide immediate separation between the nasal and oral cavities, restoring speech, swallowing, and facial contour. Over time, these devices are modified or replaced with definitive obturators tailored to the healed defect, offering improved stability, comfort, and functionality. The presentation discusses the principles guiding the selection and fabrication of interim and permanent solutions, emphasizing patient-specific considerations, material choices, and prosthetic techniques. It also highlights the importance of a multidisciplinary approach for optimal rehabilitation, detailing clinical steps, challenges, and advances in obturator design that enhance quality of life for maxillectomy patients.

This presentation introduces the digital fabrication process of a surgical obturator (SO), utilizing computed tomography (CT) data of the tumor region along with intra-oral scanner data from the patient.
The current approach enables a virtual surgical resection based on the integration of CT imaging and intra-oral scan data. The SO is fully designed using digital simulation software and manufactured through 3D printing technology. If no recurrence is detected after the healing period, the next surgical phase involves the use of a microvascular flap to close the oro-nasal communication. Simultaneously, zygomatic implants are placed to provide support for the final prosthetic rehabilitation. The initial surgical obturator is also employed as a zygomatic implant placement guide. It is re-scanned and reprinted using acrylic material to ensure accurate positioning of the implants during surgery.

Nonsurgical treatment of Class II malocclusion depends on the skeletal or dental cause, age, and severity of the deviation. In growing children, the goal is to correct skeletal growth with functional appliances with or without Headgear to limit maxillary growth. In adults, treatment tends to involve camouflage by extraction of upper premolars, use of mini screws to distalize the maxillary dental mass, or rotation of the incisor axis. Cephalometric and soft tissue analysis help determine the appropriate treatment approach. Profile esthetics, occlusal function, and patient compliance should be evaluated. Treatment should be individualized and incorporate maintenance strategies to ensure longterm, stable results.

The art of layering has long been used to create natural-looking ceramic teeth. Traditionally, feldspathic ceramics, with a vitreous matrix and fine crystalline filler, were employed. However, recent decades have seen major advancements in dental ceramics, notably zirconia and lithium disilicate ceramics.

Zirconia, valued for its toughness and flexural strength, enables the construction of extensive tooth- or implant-supported frameworks, effectively replacing traditional metallurgical structures. Lithium disilicates, with a vitreous matrix and large crystalline filler, offer notable durability and are ideal for veneers due to their excellent bonding and aesthetic properties.

This lecture will discuss appropriate indications, new concepts, and clinical protocols for dentin adhesion, with a particular focus on zirconia veneers.

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”.

However, the presence of the maxillary sinus makes implant placement difficult, and various methods have been suggested to overcome this. However, there are still many controversies, including the surgical method for maxillary sinus augmentation, and the choice of bone grafting materials.
In this lecture, I will show the current status of evidence-based maxillary sinus augmentation through various literature reviews, and I will add my own method to help the audience in their clinical practice.
Objectives:
– Selection of surgical method.
– Selection of graft material.
– Other controversies.

Abstract 1: Primary implant stability is a prerequisite for successful osseointegration, and that implant instability results in fibrous encapsulation. A high value of insertion torque (30~50 Ncm) seems to be one of the prerequisites for a successful immediate/early loading procedure.
Techniques for measuring implant stability and osseointegration, including the clinical measurement of cutting resistance during implant placement and removal torque following osseointegration, are discussed.

Two measurement methods at the micromotion-level of an implant are widely used: the self-resonance frequency analysis (RFA) method and the percussion method. The RFA method requires connecting to the implant every time a transducer called SmartPeg is measured, but there is a hassle of specifically selecting and measuring the right one depending on the type of implant. Unlike this RFA method, the percussion method has the advantage of being able to freely measure stability whenever necessary even during the healing period without removing the healing abutment (HA) or upper implant prosthesis. There is already well-known and released AnyCheck (Neobiotech Co. Ltd., Seoul, Korea).

Both measuring instruments are judged to be stable when recording a value of 70 or more as a micromotion value (ISTv).Objectives:
– Understand the requirements on implant surgery for immediate/early loading.
– Understand what are the hazards to the bones that lead to implant failure during implant surgery.
– Ensure that CMI fixation concept is understood and realized.
– Understand and practice Top-Down implant treatment concept.
– Prepare to determine the timing of loading to follow the type of implant rehabilitation.

Alveolar bone reconstruction has been one of the pre-prosthodontic treatment in the field of oral and maxillofacial surgery for a long time. However the term of alveolar bone graft was popularized with the recent advancement of implantology. The implantologist can meet frequently the cases which need alveolar bone augmentation. Sometimes the augmentation procedures show good result, but the number of failure cases increase according to the increased number of the patients.

The advantages of the interpositional bone graft may include followings. The pedicled bone segment shows relatively high resistant to infection and resorption. The crestal bone can be remained on the implant margin and more resistant to marginal bone resorption. The height of the augmentation can be achieved more than GBR to 5-7 mm. The attached keratinized gingiva can be maintained. However, the interpositional bone graft is beneficial when applied to the ridge with adequate alveolar width.

This presentation overviews the limitation of the alveolar bone augmentation, the usefulness and technical point of the interpositional bone graft with literature review.

Most dental implants consist of three main components: the fixture, which is osseointegrated into the alveolar bone; the abutment, which connects to the fixture and supports the prosthetic crown; and the crown itself. Generally, the connection between the implant fixture and the crown falls into two categories: screw-retained and cement-retained. A hybrid method known as SCRP (Screw- and Cement-Retained Prosthesis), which combines both approaches, has also been widely used. In screw-retained systems, the crown and abutment are fabricated as a single unit and secured without the use of cement. In contrast, both cement-retained and SCRP systems require an intermediate cementation step to attach the crown to the abutment.

Typically, in the patient’s mouth, the abutment is first connected to the implant fixture, and the crown is then cemented onto the abutment. However, during this process, residual cement may inadvertently remain in the peri-implant area, particularly between the implant and surrounding soft tissue. This is one of the leading causes of peri-implantitis. To address this issue, a variety of cementless implant abutments have been developed in recent years. These designs eliminate the cementation step, thereby reducing the risk of peri-implantitis and simplifying the clinical workflow. Because the crown can be placed and removed directly in the oral cavity, treatment time is also reduced. Although several types of cementless abutments are currently available, they are relatively new and still lack long-term clinical data.

In this report, I will share my clinical experience with cementless abutments, specially their advantages, disadvantages, and potential role in implant prosthetics.

In the field of dental implants, there are many procedures we perform routinely or are familiar with, yet we often lack a deep understanding of their underlying principles. Some biomaterials, once overlooked, have since proven to be valuable in clinical practice.
In this lecture, we will begin with the fundamentals. We will explore the core theories behind dental implants, share our clinical experiences, and discuss the proper application of various materials—gleaned from years of working with different bone and soft tissue repair techniques—to help prevent failure and manage complications effectively.
When implant failure does occur, how can we respond, recover, and rebuild with confidence? This lecture presents hard-earned lessons in the simplest way—through stories of both laughter and tears—aimed at enriching not just your medical knowledge, but also your perspective and attitude toward life.

Nowadays, full-arch implant rehabilitation using the All-on-4 concept is increasingly popular due to its high success rate and avoidance of complex procedures like nerve repositioning and bone grafting. In the mandible, long-term survival rates reported by Dr. Paulo Malo approach 99% with the conventional All-on-4 protocol and minimal prosthetic complications. However, the maxilla presents unique challenges: complex anatomy, variable bone resorption, pneumatized sinuses, and poor bone density, leading to failure rates of up to 30% with the traditional approach and prosthetic complications in 50% of Class III & IV cases (Malo). To address these challenges, advancements such as Bone Compression, Bicorticolization, and Eliminated Cantilever have improved survival rates (>98%) and reduced long-term complications. Additionally, techniques like Nasalis, Transnasal, Transinus, and Pterygoid implants provide more options, minimizing bone grafting and enhancing immediate loading potential. This report aims to share real clinical cases showcasing these advanced solutions.
Objectives:
– Diagnosis and Treatment planning for fully edentulous patients.
– Understanding the Principles of the All-on-4 Concept.
– Importance of immediate loading and minimizing cantilever stress.
– Challenges and Complexities of Full-Arch Implant rehabilitation in the Maxilla.
– Advanced solutions for Full-Arch Implant placement.

Immediate implant placement is increasingly favored for its advantages: fewer surgeries, shorter treatment time, and greater patient satisfaction. Traditionally, it requires a thick intact buccal bone wall and a stable gingival margin. However, with advances in surgical techniques, clinicians can expand indications to cases with buccal bone defects or gingival recession. By applying appropriate regenerative and soft tissue techniques, it is possible to maintain the gingival contour, avoid recession, reduce treatment time, and achieve optimal aesthetic outcomes. This article reviews several approaches for immediate implants in compromised sockets and presents clinical cases to illustrate their practical application.

The integration of digital technologies into implant overdenture (IOD) workflows has significantly enhanced treatment accuracy, efficiency, and patient satisfaction. Digital tools are now applied across various IOD protocols, including one-implant (1-IOD), two-implant (2-IOD), and mini-implant overdentures, offering tailored solutions for different anatomical and financial conditions. Intraoral scanning ensures accurate, distortion-free capture of implant sites, while CAD/CAM systems enable precise virtual design. 3D printing supports efficient fabrication of surgical guides, try-ins, and final prostheses, improving fit and retention. Recent studies (2020–2025) show favorable clinical outcomes, especially with guided digital planning in 1-IOD and biomechanical advantages in mini-implant overdentures. However, challenges remain, including high equipment costs, training demands, and a lack of protocol standardization. Long-term data are also limited for digital 1-IOD and mini-implant cases. This presentation reviews current digital applications in IOD therapy and explores future directions, including AI integration for predictive prosthodontics.
Objectives:
– Update on digital technology applications in implant overdenture (IOD) workflows, including intraoral scanning, CAD/CAM design, and 3D printing across 1-IOD, 2-IOD, and mini-implant configurations.
– Analyze clinical benefits and practical challenges of digital workflows based on recent evidence (2020–2025).
– Explore future directions in implant prosthodontics, including the integration of artificial intelligence.

Missing teeth are a very common problem, which can be congenital or secondary. To restore these teeth, ceramic restorations are a popular technique. All-ceramic resin-bonded bridge have been introduced as an esthetic solution for missing anterior teeth. With the continuous development of ceramics and bonding materials, these restorations open up many promises in terms of aesthetics and durability. However, the design of all-ceramic resin-bonded bridge is still a subject of debate, with some clinicians believing that bilateral bonding is necessary, while others believe that a single wing is sufficient. So, the question is, which design is better?
Objectives:
– Overview of bonded bridges.
– Evidence for the feasibility of the Single-Wing design.
– Clinical evidence for the efficacy of the One-Wing and Two-Wing designs.

The acellular bovine bone (bCB) was implanted in rabbit calvarial as following method: screwed a titan cylinder (inner diameter x height, 5 x 5 mm) into rabbit calvaria, drilled a hole in the area covered by cylinder to facilitate bone marrow, implanted bCB. Each rabbit had 4 cylinders, 3 of which were filled with autologous bone (Auto), bCB, BioOss per cylinder, and the last one was empty (total 12 rabbits). After 4 months, based on CT scan, X-ray, and Haematoxylin/Eosin staining, the results showed that new bone blocks were completely formed in all cylinders implanted with bCB and inflammation was not observed. The results were similar to that of BioOss and Auto. Conclusion: bCB supported bone formation as well as commercial bone.

Clear aligners have revolutionized orthodontic treatment beacause of their aesthetics and convenience. However, they still have limitations in controlling complex tooth movements such as extrusion, intrusion, molar distalization, and efficient space closure after extractions. The combination of clear aligners with Temporary Anchorage Devices (TADs) offers a novel approach to overcome these limitations. TADs allow direct force application to target teeth without relying on adjacent teeth, thereby minimizing anchorage loss and enhancing control in cases requiring anterior intrusion, full-arch distalization, or precise moment/force management in complex movements. This report outlines the biomechanical principles of combining clear aligners with TADs, clinical indications, placement techniques, and monitoring protocols. This synergy not only improves treatment efficiency but also expands the indications of clear aligners to cases previously manageable only with fixed appliances.

The sliding hook mechanism perfectly replaces the role of the hook on the archwire in closing the space, opening the space, and moving the teeth by the biomechanical system that creates a balanced moment while simultaneously creating a force-disconnecting mechanism in en mass retraction, opening the space for a tooth that is impacted or congenitally missing, correcting midline deviation, and minimizing complications during treatment that are fast, pure bodily movement and safety. This mechanism helps doctors learn and practice easily, creating maximum comfort for patients.
