Summary in English

The Department of Removable Partial Prosthodontics specializes in removable partial denture treatment, which is one of the major disciplines of clinical dentistry. The department has taken the baton from the First Department of Prosthodontics and the Department of Masticatory Function Rehabilitation.

Our objectives are to enhance the art and science of removable prosthodontics for the management of various oral conditions associated with tooth loss, from a single missing tooth to a single remaining tooth, in the maxillary and/or mandibular arch.



Research

1. Function and Physiology in Partial Denture Wearers

2. Optimization of Partial Denture Design based on Stress Analysis

3. Development and Applications of New Biomaterials to Prosthodontics

4. Biology of Oral Tissues in Denture Wearers

5. Epidemiology and Education for Removable Partial Prosthodontics



Education

The Department of Removable Partial Prosthodontics offers a variety of educational courses pertaining to the specialized clinical management of tooth loss, primarily for undergraduate students at the School of Dentistry. The courses include lectures, tutorials, hands-on sessions, clinical simulations, and clinical internship instructions.

The ability to perform clinical operations on patients with tooth loss, including the skills required for medical interviews, oral examinations, diagnosis, decision making, impression making, bite registration, denture design and technology, and denture delivery and maintenance, is essential for clinical dental professionals. The objectives of our courses are to provide learning and training in contemporary removable prosthodontics and enhance the knowledge and skills of students to help them develop and flourish in their future career as dental and oral health professionals.



Clinical Activity

All faculty members of the Department of Removable Partial Prosthodontics are assigned to treat patients at the Prosthodontics department in the Dental Hospital of the Tokyo Medical and Dental University. While the rate of tooth retention has increased in comparison with previously reported rates, the number of patients in need of a removable partial denture has increased. Our specialists primarily work on advanced cases that are referred from other departments and outside the hospital. The departmental mission also includes the development and application of new prosthodontic materials, their clinical trial, and the spread of novel and inventive knowledge to the community.



Specialty in Practice

The department specializes in removable partial prosthodontics and aims to restore missing teeth and associated oral tissues; improve physiological functions such as occlusion, mastication, swallowing, and speech; maintain normal oral sensation; and restore the original appearance of individual patients. Treatment modalities, materials, and denture design are all based on the case history and chief complaint of the patients. The ultimate goal is to improve the oral health-related quality of life of patients.


Program Objectives

The PhD Program in Removable Partial Prosthodontics provides advanced training in research and science for postgraduate dentists who may be concurrently enrolled in specialty programs. The program objectives are to provide training in modern prosthodontic research methods and equip students with the ability to critically analyze research and clinical literature. This training will prepare dental graduates for clinical faculty positions and enhance opportunities for careers as specialists in prosthodontic practice.

Specific Activities in Research

Effect of a shortened mandibular dental arch on human brain activity during chewing

When molars are lost (for example, due to periodontitis or dental caries), dental arch is shortened and ability to chew foods is decreased. However, it remains unknown whether shortened dental arch has effects on brain activity during chewing.
To investigate this question, experimental removable partial denture was fabricated, in which length of artificial molar arch is interchangeable. Brain activities (activated regions) during chewing test foods were revealed using a functional neuroimaging method, and were compared between changed lengths of the arch.


The evaluation of prosthodontic treatment outcome based on jaw movement smoothness

Movement smoothness is a measure of human motor performance. Smoothness of jaw movement is closely associated with masticatory function and has potential use in the evaluation of masticatory disorder risk.
We developed a 3D accelerometer measurement system which is inexpensive and small that can be used during chewing to monitor and analyse the jerk and jerk-cost of jaw movements.
The ultimate goal of our study is to develop an evaluation system that enables clinicians to judge their prosthodontic treatment outcome.


Investigation on the influence of different materials and components of removable partial dentures on the material strength.

Denture fracture is one factor for failures in removable partial dentures. The fracture resistance of acrylic denture base, either for conventional or for implant-supported dentures, is one of the important factors in terms of safety, longevity, and patient satisfaction of removable prosthodontics. Analysis of the fracture mechanisms is absolutely necessary when materials and components of removable partial dentures are changed. We have investigated the fracture resistance of different materials and components of removable partial dentures.

Optimization of Partial Denture Design based on Stress Analysis.

Denture fracture is a factor for failure of removable partial dentures. The fracture resistance of an acrylic denture base, either in conventional or implant-supported dentures, is one of the important factors in terms of safety, longevity, and patient satisfaction. The analysis of mechanisms underlying fractures is absolutely necessary when materials and components of removable partial dentures are changed. We have investigated the fracture resistance of different materials and components of removable partial dentures.


Development and Applications of New Biomaterials in Prosthodontics

Denture stomatitis is a common form of oral candidiasis that develops with the adherence of Candida albicans to denture base surfaces. Acrylic resins are commonly used for denture bases, may act as reservoirs for microorganisms, and have the potential to support biofilm formation. We have evaluated the inhibitory effects of acrylic resin combined with newly developed fillers on biofilm formation by C. albicans.
