Dynamic vs. Static Jaw Relations in Implant-Supported Prostheses: Chewing Efficiency

Brief Summary

This study aims to compare the chewing efficiency of implant-supported full-arch prostheses fabricated using two different jaw relation registration techniques: conventional static jaw relation registration and dynamic jaw tracking. Ten completely edentulous patients will be recruited from the Department of Removable Prosthodontics, Faculty of Dentistry, Mansoura University. Each participant will receive implant-supported full-arch prosthetic rehabilitation according to the All-on-6 concept. Two definitive zirconia prostheses will be fabricated for each participant, one using conventional static jaw relation records and the other using dynamic jaw tracking records, in a crossover study design. Chewing efficiency will be evaluated using a two-color chewing gum mixing test at the time of definitive prosthesis insertion, three months after insertion, and six months after insertion. The degree of color mixing will be analyzed using dedicated image-analysis software. The study will investigate whether dynamic jaw relation registration provides different chewing efficiency outcomes compared with the conventional static technique in patients rehabilitated with implant-supported full-arch prostheses.
