Elastic silicone matrices as a tool for load relief in overdenture implants

The objective of this study was to analyze how the elasticity of matrices attaching to an overdenture affects implants and how the location of implants affects their loading. The attachments proposed made from elastic matrix increase the denture stability and simultaneously preserve the mechanisms of occlusion load transfer in compliance with principles usually applied in the denture used in the case of edentulous maxilla or mandible. It was revealed that denture dislodgement caused by occlusion forces did not result in the force being greater than the attachment retention force determined empirically. Our analysis also demonstrates that in the case where the implants are inserted in such a way that they are shifted too much to the back area of the tooth arc, an increase in the implant bending occurs, with the supporting capacities of alveolar processes not being fully utilized. This fact suggests the necessity to increase the susceptibility of attachments in a posterior location.
