Abstract

Purpose: To investigate the effects of prosthetic load on crestal bone loss within the maxillary and mandibular arches of a single individual.

Materials and Methods: This study evaluated 10 implants from a single patient, 5 each from the maxillary and mandibular arches, with a follow-up of 12 months. Implants were assessed hinged to the load that is applied by the prosthesis mesial and distal points P1 and P2. Crestal bone loss was quantified by measuring bone level changes using cone beam computerized tomography (CBCT). Time T1 was defined as 3 months after implant placement, and T2 as the term after 12 months of implant positioning, follow-up visit. Group comparisons will be made using the Wilcoxon signed rank test, with significance set at p<0.05.

Result: A statistical significant difference was present and the mean crestal bone loss after prosthetic load is higher than preload; higher in maxillary arch when compared to that of mandibular arch in same individual.

Conclusion: In this study, crestal bone loss was higher in maxillary arch after prosthetic load rather than mandibular arch and preload.
