Evaluating chewing performance in patients with implant-supported dentures
Official title: Effect of Implant Supported Fixed Restoration on Masticatory Efficiency in Patients With Second Molar Loss
Run by National Taiwan University Hospital · NCT06581614 · Data updated 2026-11-12
This study is testing how well people with implant-supported dentures can chew using a special chewing gum to see if these dentures improve their chewing ability.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are patients who have lost their second molar and are scheduled for single-implant reconstruction without major health issues.
✕Probably not a fit
Patients with severe temporomandibular joint disorders or those unable to comply with the treatment schedule may not benefit from this study.

What this trial studies
This observational study aims to assess masticatory efficiency in patients who have lost their second molar and are receiving implant-supported fixed dentures at the Prosthodontics Department of National Taiwan University Hospital. Participants will undergo masticatory function tests using a new chewing gum to evaluate the impact of these prosthetic reconstructions on their chewing ability. The study seeks to enhance patient well-being and provide insights into the effectiveness of dental implants in restoring chewing function. By combining research on chewing efficiency with prosthodontic expertise, the study aims to inform future strategies for dental reconstruction.
Why it matters
Potential benefit: If successful, this study could improve chewing efficiency and overall quality of life for patients with missing molars who receive implant-supported dentures.
How similar studies have gone: While there is existing research on masticatory efficiency, this specific approach combining prosthodontics with a focus on implant-supported dentures is relatively novel.
