The aim of this study is to evalute the preload maintenance of retention screws of conical abutments and cylinders of internal hexahon joints submitted to retightening and measurement of detorque value. Two groups (n=12) will be characterized according to the different components attached to the external hexagon implant: Group I - conical abutment attached to the implant through titanium retention screw, Group II - cylinder attached to the conical abutment through titanium retention screw. After three minutes, detorque values will be measured by an analogic torque gauge. This measurement will be carried out 10 times for each retention screw of groups I and II, totalizing 120 detorque measurements in each group. Data will be tabled and submitted to statistical analysis.
