Brief Summary

The purpose of this experiment is to combine research on masticatory efficiency with the reconstructive expertise of the prosthodontics clinic, focusing on implant-supported fixed dentures as the contemporary gold standard for reconstruction. The goal is to investigate the impact of such prosthetic reconstructions on masticatory efficiency. We will invite patients who have lost their second molar and have undergone single-implant-supported fixed denture reconstruction at the Prosthodontics Department of National Taiwan University Hospital to participate in masticatory function tests. The tests will use a new and relatively simple chewing gum, with the aim of enhancing patients\' masticatory function through implant reconstruction in a clinical setting, thereby improving patient well-being and understanding of dental implants. On the research side, the study aims to provide guidance for strategies in the reconstruction of masticatory function.

Conditions

Masticatory Performance

Keywords

implant supported fixed prosthesis; masticatory efficiency; chewing gum

Outcome Measures

Primary Outcomes (1)

• the masticatory performance of patients

  During the test, participants will be given a piece of chewing gum to assess their masticatory function when the second molar implant-supported fixed restoration is in place.

  After second molar implant reconstruction was done(at least 1 month after reconstruction)

Study Arms (2)

prospective group

Patients who have lost their second molar, are scheduled to undergo single-implant reconstruction at the Prosthodontics Department of National Taiwan University Hospital, and do not have any major physical or mental health conditions

Diagnostic Test: masticatory function test

retrospective group

Patients who have lost their second molar, have undergone single-implant-supported fixed restoration reconstruction at the Prosthodontics Department of National Taiwan University Hospital, and do not have any major physical or mental health conditions.

Diagnostic Test: masticatory function test
