Trial Parameters
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.
Eligibility Criteria
For prospective group: Inclusion Criteria: * 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. Exclusion Criteria: * Severe temporomandibular joint disorder * Inability to comply with the treatment schedule * Inability to cooperate with masticatory function tests * Lack of opposing teeth for the implant-supported restoration * Patients whose anterior teeth will be included in the prosthetic reconstruction or whose occlusion will undergo significant changes after reconstruction For retrospective group: Inclusion Criteria: * 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. Exclusion Criteria: * Implant-sup
