| Outline of Final Research Achievements |
We developed a small-sized retentive force measurement device which can be easily measured on the chair side. Then we verified the performance of the device by measuring the reproducibility of clasp retentive force. We clarified the retentive force of various retentive devices on a working model by the measurement device.From the measurement results, this study clarified the average retentive forces of 11 retentive devices. In principle, maintenance was carried out every month, Check items during maintenance were occlusal contact, mucosal fitting of dentures, oral cleaning, and periodontal examination. Retentive force measurement (RF value) of the maintenance device by using a small-sized retentive force mesurement device, and tooth mobility measurement (PT value) by using Periotest M were performed.It was possible to observe using objective numerical values when adjusting the partial denture which is subjectively performed in daily clinical practice.
