Digital Analysis of Occlusal Force Distribution in Single-Tooth Implant Restorations

Completed

• Conditions: Occlusal Analysis

• Registration Number: NCT06862973
• Lead Sponsor: Konya Necmettin Erbakan Üniversitesi

Brief Summary

This study will explore the impact of single tooth implant restorations upon occlusal force distribution and the accuracy of several digital analysis methods. The biomechanical behavior of implant-supported prostheses differs from that of natural teeth, and the distribution and modulation of occlusal forces are unpredictable.

The research used the Medit i700 intraoral scanner and the OccluSense system to take pre- and post-implant measurements. The research aims to determine: How are the techniques different in the registration of occlusal contacts and force magnitude? and How does occlusal balance shift following the placement of an implant? The research findings can be used to provide clinical recommendations to optimize occlusal balancing during implant prosthetics.

Primary Outcome Measures

Name	Time	Method
Change in Occlusal Force Distribution from Pre-Implant to Post-Implant Restoration as Measured by Medit i700 and OccluSense	From pre-implant assessment to 2 week after final implant restoration placement.	Occlusal force distribution was measured before and after single-tooth implant restoration using two digital occlusal analysis methods: Medit i700 intraoral scanner and OccluSense pressure sensor system. Measurements were taken under standardized conditions, ensuring maximum intercuspation position. Medit i700 provided contact area data through intraoral scans, analyzed with CloudCompare software, while OccluSense recorded occlusal force intensity and distribution, analyzed with ImageJ software. The percentage change in occlusal contact areas and force distribution was calculated between the pre- and post-implant conditions. A statistically significant change (p \< 0.05) indicates an alteration in occlusal balance following the restoration.
