Divergence of Implants and Asymmetry of Fixed Prosthesis on Implants Case Report

Abstract

This report presents the case of a 62-year-old man, who went to the dentist's office in May 2022 to rehabilitate the edentulous maxillary area. It was planned to place implants in positions 16, 14, 12, 22, 24, and 25, with a delayed technique in the placement of the fixed prosthesis. The implant 24 had a divergent position towards buccal. There was also an asymmetry in the prosthesis, since implants 24 and 25 were closer to each other, to avoid the proximity of the maxillary sinus on the left side, while piece 16 could be placed on the right side. The non-parallel placement of an implant is not a complication, but rather an unscheduled inconvenience. In many cases, it depends on the availability of bone to be able to place the implants in the positions programmed as ideal. To improve esthetics in screw channel 24, a making agent was applied. We have found it more reasonable to place tooth 16, even though it results in an asymmetric prosthesis. It is a tooth that is useful for the patient to chew and the asymmetry is minimal, concerning the whole of the prosthesis. Bone limitations in width and depth condition the position and angulation of the implants. The divergence and asymmetry of these implants also condition the way of making the fixed prosthesis on them. The choice between a cemented or screw-retained prosthesis is not essential, since in both cases a good oral, functional, and aesthetic restoration can be made.
