Abstract

The purpose of this study was to evaluate mechanical fit of fixture- abutment-screw interface in the internal connection implant systems. In this study, each two randomly selected internal implant fixture- abutment assemblys from Certain, Xive, Replace, Ankylos, SS II. were used. The implants were perpendicularly mounted in liquid unsaturated polyester by use of dental surveyor. Each abutment was connected to the implant with recommended torque value using a torque controller. All samples were cross-sectioned with grinder-polisher unit after embeded in liquid unsaturated polyester, and then fixture-abutment-screw interfaces of all samples by using optical microscope and scanning electron microscope were analyzed. Conclusively, although a little variation in machining accuracy and consistency was noted in the samples, important features of all internal connection systems were the deep, internal fixture-abutment connections which provides intimate contact with the implant walls to resist micromovement, resulting in a strong stable interface.
