As internal junctions, an external-hex butt joint, axial preload of the abutment screw stabilizes the connection between the abutment and the implant fixture. In the past I used to just torque down the abutment screw to whatever the dental implant manufacturer recommends and then cement the crown or bridge. HHS Smileloc leads their mission to set a new standard for implant dentistry. A wide variety of abutment materials are available on the dental implant market. As a result, manufacturer-made abutments and custom-made abutments evolved that allowed them to be placed in proper angulation, and they became the primary abutments for single crowns placed over abutments. The largest torque value was maintained in uncoated screws with external hex connections, a finding that was statistically significant (P = .0001). It also keeps your remaining teeth from shifting out of alignment. 1. Jorge JR, Barao VA, Delben JA, Assuncao WG.
