Removable Prosthodontics and Gerodontology Lab
Machine-translated · View original
A lab that uses data to explore dentures, implants, and the oral health of older adults.
AboutAbout the lab
Aiming for predictive dentistry based on data.
The Removable Prosthodontics and Gerodontology Lab conducts basic and clinical research related to removable dentures and dentistry for older adults.
Its goal is predictive dentistry based on data science, and it also conducts research on implant-supported prosthodontics.
Taking advantage of being part of a comprehensive university, the lab collaborates with a wide range of fields such as medicine and engineering, pursuing epidemiological surveys, AI, and mechanical experiments.
Formerly called the Second Department of Prosthodontics, the lab was founded in 1953 (Showa 28).
Key terms
- Prosthodontics
- The field of replacing lost teeth or parts of teeth with artificial substitutes.
- Removable denture
- A denture that replaces missing teeth and has a supporting base (denture base).
- Cohort study
- A study that follows the same group of people over time to examine how lifestyle and health conditions relate to diseases and other outcomes.
- Strain gauge
- A sensor that measures the deformation (strain) produced in an object when force is applied.

ResearchResearch themes
The lab aims for predictive dentistry based on data science and carries out clinical and basic research on prosthodontics using removable dentures and implants. Taking advantage of being part of a comprehensive university, it conducts research in collaboration with a wide range of fields such as medicine and engineering.
*Illustrative imageOral and systemic health of older adults
Working with researchers in medicine and other fields, the lab investigates the relationship between oral health and systemic health through large-scale cohort studies of older adults and elementary school children. These include the SONIC Study, the OHSAKA Study, and the Osaka MELON Study.
*Illustrative imageClinical epidemiology of treatment outcomes
Using clinical databases, the lab examines implant treatment outcomes and the factors behind the functional success of complete dentures. In maxillofacial prosthetic treatment, it studies oral function in oral cancer patients, and it also conducts epidemiological studies on the effects of mouthguards.
*Illustrative imageApplying AI to dentistry
As part of S2DH, an industry-academia collaboration project led by Osaka University Dental Hospital, the lab conducts research using AI. It automatically recognizes prostheses and implants from intraoral photographs and radiographs, and also simulates tooth loss.
*Illustrative imageMechanical studies of dentures and implants
In model experiments using strain gauges, the lab measures the strain generated in dentures and implants and examines how it changes under different conditions. For free-end (distal extension) dentures, it aims to clarify the factors that affect denture behavior and the load on the remaining teeth, and to establish methods of preventing tooth loss.
