Rehabilitation with implants, prostheses basically have two retention arrangements, for screw or cement. There are several important factors to achieving success in implantology that can influence decisively in choosing the type of detention, such as occlusion, aesthetic crown and soft tissue, passive adaptation, cost and ease of manufacture of the prosthesis. The aim of this study was to discuss the advantages and disadvantages between the two types of prosthetic implant, or concreted and bolted. It was concluded that both cemented prosthesis as the screw can be properly used according to the clinical situation presented. There is no evidence to support, in general, a retaining mechanism over the other.
