Morse Taper System and platform switching abutment application

Abstract

Morse taper implants associated with platform switching abutments have provided promising results with respect to the stability of peri-implant tissues. This is due to the narrower diameter of the conical abutment in comparison to the implant platform, and the intimate adaptation at the implant/abutment interface, which contributes to lower accumulation of bacterial biofilm. For this, several investigations have proposed the insertion of the morse taper implants below the crestal bone level. The maintenance of crestal bone provides oral rehabilitation with aesthetic and biocompatible prostheses. Studies assessing mechanical properties have shown that this type of implant/abutment configuration presents higher fracture strength when compared to conventional systems. In addition, various options of abutments and prosthetic components are other positive points for prostheses made with this type of system.
