The preload on the screw refers to loading immediately after being cramped, with a key to the stability and success of implant / prosthesis connection factor. This study aims to analyze the effect of some sealing materials inserted into the surface of the retaining screw on the maintenance of preload these screws. For this, we formed four groups (n = 10) of abutment / implant systems with external hex connection and UCLA abutments anti-rotational strap with alloy Cobalt / Chromium (Co-Cr). In each test group a material interface at the implant / abutment screw is inserted: Group I (control) - the specimens of this sample did not receive any kind of material at their interface; Group II - will be implemented anaerobic glue chemical lock to Medium Torque; Group III - Implementation of a chemical lock High Torque; Group IV - will be using a cyanoacrylate adhesive. All pillars are screwed to the implants with a torque of ± 32N/cm 1N/cm applied clockwise with the aid of a torque meter (torque wrench). After a period of 48 ± 2 hours of applying the initial torque measurements of values detorque will be performed using the same equipment as the initial applied torque. The data will be tabulated and submitted to appropriate statistical analysis
