INTRODUCTION:

Implant-supported prostheses have to overcome a major difficulty presented by the morphology and esthetics of peri-implant tissues in the anterior sector. Diverse therapeutic techniques are used for managing the mucosa adjacent to the implant and the most noteworthy is immediate/deferred fixed provisionalization.

OBJECTIVES:

In vitro testing of strength and deformation of implant prosthetic abutments made from different materials(Titanium/PEEK/methacrylate).MATERIAL AND

METHODS:

Forty Sweden & Martina(R) implant prosthetic abutments (n=40) were divided into five groups Group MP methacrylate provisional abutments with machined titanium base; Group PP Polyether etherketone (PEEK) provisional abutments; Group TP titanium provisional abutments; Group TAD titanium antirotational definitive abutments; Group TRD titanium rotational definitive abutments. Their mechanical behavior under static loading was analyzed. Samples were examined under a microscope to determine the type of fractureproduced. Results and

CONCLUSIONS:

Definitive anti-rotational titanium abutments and definitive rotational titanium abutments achieved the best mean compression strength, while PEEK resin provisional abutments obtained the lowest. The group that showed the greatest elastic deformation was the group of titanium provisional abutments
