Evaluation of the Effects of Hybrid Prostheses Prepared from Different Materials on Pterygoid and Cancellous – Anchored Posterior Maxillary Implants of Varying Lengths Using Three – Dimensional Finite Element Analysis

Different substructure materials have varying effects on the prosthesis, bone, and implant. It is suggested that the use of substructure materials with high elastic modulus would be more appropriate to reduce potential prosthetic complications in hybrid prostheses and achieve predictable stress distribution in the bone. The use of maxilla-restricted dental implants should be considered when sufficient cortical bone anchorage is present around the neck region of the implants. However, in cases where cortical bone support in the neck region is insufficient, the use of implants providing bicortical anchorage may be more beneficial.
