MECHANICAL TESTING OF CUSTOMIZED AND COMMERCIAL TITANIUM CHIN PLATE DURING SIMULATION OF 8-MILLIMETER ADVANCEMENT GENIOPLASTY USING THE SYNTHETIC MANDIBULAR MODEL

Abstract

The objective of this research is to compare the ability of a customized titanium chin plate and a commercial titanium chin plate to accommodate forces simulating the action of the suprahyoid muscle during stimulated advancement genioplasty. Additionally, this study aims to compare the performance of two different designs of customized titanium chin plates (4-hole and 5-hole) in accommodating forces during stimulated advancement genioplasty, using a universal testing machine. The results of the study indicated that: 1) the maximum force that different plate and screw systems can withstand before failure was significantly higher in the customized chin plate group. 2) There was no significant difference in the ability to withstand tensile loads between the 4-hole and 5-hole customized titanium chin plates.
