In the past two decades, advances in endodontic biomaterials science have contributed significantly to the dramatic growth of the field of dental traumatology. The bioactive, regenerative, and restorative potential of modern bioceramic materials have revolutionized treatment options in the emergency management of traumatic dental injuries such as pulp exposure and long-term posttraumatic complications such as infected immature teeth and root resorption after dislocation or fracture of teeth. New forms and types of bioceramic materials are now being proposed for the appropriate management of traumatized teeth. The purpose of this presentation is to provide an overview and classification of the bioceramic materials currently used in the field of dental traumatology, based on their material composition and clinical applications. It will also discuss how the proper selection and proper handling of bioceramic material types based on different dental trauma scenarios can significantly improve the long-term survival of traumatized teeth. ※This is a lecture from the 22nd World Congress of the International Society of Trauma Dentistry (WCDT2024), held July 12-15, 2024.

Take-home message

With proper diagnosis and treatment, the pulp and tooth can be preserved and long-term esthetics and function restored in most cases of traumatized teeth. However, delayed reimplantation of debrided teeth or root fractures with multiple root fractures may be difficult to preserve. In such cases, prosthetic treatment using autografts, implants, or bridges is generally used. However, autografts require an appropriate donor, implants have a high risk of low occlusion, especially in younger patients, and bridges require the formation of abutment teeth in both adjacent teeth, which carries the risk of pulpal necrosis. In such cases, bonded bridges may solve these problems. However, the success rates of bonded bridges reported so far are lower than those of autografts, implants, and bridges, so proper knowledge of the selection of the indications, the design of the formation, the choice of materials, and bonding is essential. In this lecture, I will discuss the scientific basis and clinical points of adhesive bridges. ※This is a lecture from the 22nd World Congress of the International Society of Trauma Dentistry (WCDT2024), held July 12-15, 2024.

Summary

Autologous tooth transplantation (Autotransplantation of teeth) has been around for decades, but its popularity has fluctuated due to the unpredictability of its results. However, recent advances in technology and improved understanding of biology have improved the predictability of autotransplantation of teeth. Still, many clinicians lack confidence in the technique. This is due in part to a lack of research on long-term case results. As a general practitioner, I have performed over 1,000 autologous tooth transplants since 1984. Most of these cases have been documented in detail with photographs and x-rays in a standardized fashion and many have been followed up over time. In this presentation, I hope to discuss the benefits of autologous tooth transplantation, sharing my own lifetime experience. ※This is a lecture from the 22nd World Congress of the International Society of Trauma Dentistry (WCDT2024), held July 12-15, 2024.

The progress of digital technology in dentistry is unstoppable, and clinical practice is now impossible without digital technology. In particular, the development of free software has been remarkable, and it is now possible to do many things without using paid software, such as tooth segmentation from CBCT and surgical simulation of autograft. In my lecture, I would like to present my digital workflow on how to create 3D tooth replicas and its digital application to autografting, especially in orthodontic patients. ※This is a lecture from the 22nd World Congress of the International Society of Trauma Dentistry (WCDT2024), held July 12-15, 2024.

I will discuss how to plan the treatment for anterior tooth loss.&nbsp; There are various causes for anterior tooth loss,&nbsp;including caries, root fractures, periodontal disease, congenital absence, and trauma. If the cause of the loss is not addressed properly,&nbsp;and the treatment is not planned well, the risk to adjacent and opposing teeth increases,&nbsp;potentially leading to further complications. When tooth loss occurs, changes in the oral cavity can be observed.&nbsp; For instance, when an er tooth is lost, adjacent teeth may tilt, and opposing teeth may extrude.&nbsp; This results in a smaller occlusal area, increasing the load during chewing and potentially leading to overloading. Additionally, these changes can contribute to the progression of periodontal disease.&nbsp; The resulting reduction in occlusal vertical dimension&nbsp;can lead to anterior teeth interference and accelerated periodontal issues. the treatment process for fixing missing front teeth. It shows the steps from diagnosis to treatment. First, we collect information from the patient's medical history and interview. Next, we do detailed examinations. Then, we use this data to make a diagnosis and treatment plan. This way, we make sure we have the right treatment plan before starting.

Periodontal regeneration therapy has become less invasive over time.Recent surgical procedures are minimally invasive and have a limited field of view, making it difficult to operate curettes.That’s why I use the Erbium YAG laser in periodontal regeneration therapy.We will show you periodontal regeneration therapy using Erbium Yag laser for intrabony defect and furcation lesion.Also,close primary closure of the incision line in the retromolar region is extremely difficult in surgical procedures on the distal of last molars, especially in the second molar.Therefore, we developed L-EPPT as a method to avoid distal incision of the last molar.This literature was accepted by JPRD in January 2024.In this presentation, we will introduce periodontal regeneration therapy using Erbium YAG laser and L-EPPT.

*Purchase to view the full video My topic of today's presentation is revisiting treatment strategies for periodontally compromised teeth in the aesthetic zone, which is a very challenging situation. I think everybody has a concern in daily practice. So first of all, when it comes to thinking about intraoral aesthetic treatment planning, there is a fundamental objective to be taken into consideration. It sounds like a lot, but quite basic stuff, and then besides those elements, intraorally, we have to think about how to evaluate the smile and the face frame outside of the intraoral element. So in terms of the patient's replant smile we care about how much gingiva displays the patient exports. According to a classic smile classification by Dr. Miller there are three types of replant smiles. First thing is a low replant smile, the patient doesn't expose any gingiva display at the smile. Adelaide's Repline SMI, the patient exposed soft tissue, interdental space only. Highly plant SMI, the patient displays all margins of soft tissue. So that classification was quite famous a long time ago, but classification is only a classification. Sometimes it's not practical to elaborate on the actual treatment plan, especially the high plan because it varies a lot. So some patients show more and some patients show less. That's why it's kind of difficult and sometimes we need to modify this like a smile classification.&nbsp; - Excerpt from the beginning of the lecture.

Abstract:
In recent years, the aging rate of Japan’s population exceeded 28%; our country has become a super aged society.

 

Recent research has revealed that oral status is related to life expectancy, and “frailty” is one of the problems we face in a super aged society. With ageing, people slowly become weak due to a gradual decline in mental and physicalfunction. As a result, their independence level in daily life gradually decreases and, eventually, they will decline into a status of requiring long-term care.

 

There is a concept of “oral frailty” being related to “systemic frailty”.

The measurement of oral frailty can give people an early warning not to fall into the negative downward spiral as follows: neglecting slight declines in oral health and leaving those conditions untreated eventually leads to deterioration of oral function, which impairs eating function, and evetually deterioration in mental and physical health.

This decrease in oral function, so called “oral hypofunction”, should be managed by dental professionals for early detection of overall frailty. 

 

In this lecture, I will explain about the concept of frailty, oral frailty, oral hypofunction, and methods to assess oral function.

Conclusion 

This video includes all of the following videos from Course15 Basic provisional restoration. [#1 Tooth Preparation Requirements] What are the requirements for abutment formation as a pre-prosthetic procedure? It is not just a matter of cutting, but the requirements depend on the final material to be used. Formation is also related to the maintenance of the provisional restoration. This session will be discussed in detail using actual cases, photos, and videos. [#2 Various pre-prosthetic treatments] Esthetics is not the only requirement for a provisional restoration. It is important how to reproduce the condition of the oral cavity and to be aware of the final restoration, and furthermore, how to reflect the record of the provisional restoration in the final restoration. He also discusses internal bleaching and gum peeling as pre-prosthetic procedures. [#3 Dealing with problems] Provisional restorations also serve as a communication tool for discussion and exchange of ideas with the technician and patient in determining the form of the final restoration. Inappropriate provisional restorations can cause inflammation of periodontal tissues, whereas appropriate restorations can help manage the soft tissues. Please take a look at Dr. Uchiyama's innovations. [#4 Role of the provisioner] In the first half of the presentation, he explains a video showing the revision of a provisional restoration, allowing the viewer to confirm the change in gingival inflammation after the revision. He also explains the difference between temporary crowns and provisional restorations, and explains in detail the various roles that provisional restorations play, along with case photos. [#5 Application to orthodontics] Provisional restorations are often applied in orthodontic treatment. The lecture presents a case study in conjunction with orthodontic treatment and discusses in detail the series of steps from the completion of orthodontic treatment to the final restoration. In the latter half of the lecture, he explains each point of the abutment tooth formation considering gingival homeostasis, from gingival anatomy to actual treatment videos. [#6 Tissue Management] Continuing from #5, the article explains in detail, with key points, each step up to the setting of the provisional restorations after the formation that takes gingival homeostasis into consideration. The number of treatment sessions until the final impression is also affected by how much pre-treatment is done at the initial visit. The patient's gingival as well as abutment tooth coloration has been changed by not only setting the provisional restorations but also performing the internal bleaching at the same time. [#7 Points of impression taking] This case is a continuation of #6 and shows the series of steps from gingival indentation after final formation and impression taking to the final prosthesis. He explains the method of gingival indentation and the detailed tips for impression taking, which is important for the creation of the prosthetic. In addition, there are cases where there are no crowns in the original prosthetic treatment. In such cases, he explains what should be kept in mind and the reason why the Initial Prep and Final Prep are done separately. [#8 Setting up an emergence profile] In the first half of the video, he explains how to reflect the canine guidance set in the provisional restoration in the final restoration, following #7. The second half of the video focuses on molar restorations and explains in detail how to set the emergence profile, which tends to be lost during the wash process. [#9 Impression taking from Final Preparation] This is a continuation of the case #8 in which Initial Preparation was performed. After removal of the provisional restoration, Final Preparation is performed, impressions are taken, and the provisional restoration is readjusted. The difference between the Initial and Final preparation, gingival indentation, and each step of impression taking are explained in detail.
