Modern Approaches in Choosing Materials for Implant Supported Prosthesis

Abstract

The materials used in manufacturing the implant supported prosthesis may influence the occlusal stress distribution to the bone due to their different elastic modulus. Thus, compared with alloys of Co-Cr, the material currently used for the realization of the implant supported prosthesis’ resistance structure, the titanium prosthesis’ elasticity allows a less rigid solidarization, especially important as the extent of the bridge is greater, more so in the mandible, which presents an elastic deformation during mastication.The use of modern composite materials based on polyether-ether-ketones for manufacturing the implant supported prosthesis’ resistance structure is gaining more and more interest due to optimization opportunities of the distribution of masticatory forces around the implant.Regarding the aesthetic component of the implant supported prosthesis, ceramic masses remain the most commonly used materials due to their outstanding restorer options and proven biocompatibility. However, speaking of the transmission of forces to the implant support, the composite materials are preferred due to advantages related to the possibility of stress relief and to ensure a durable link frame - composite, the aesthetic result being more than satisfying.
