Implant collar

A dental implant consists of four parts, top to bottom: the cover screw, the implant abutment interface, the implant collar, and the fixture. The implant collar is close to the top of the implant and sits just at the bone. One of the most important indicators of implant success is osseointegration, or the fusion of bone to the surface of the dental implant which was introduced by Branemark in 1952. In the early days of implant dentistry, the implant collar was smooth and polished to avoid irritating sensitive gum tissue which the collar may also come into contact with. In the 1980s, dental implantologists began to understand the value of implant hardware with rough surfaces. Osseointegration occurs much more consistently when a rough surface is used, even up to the implant collar. Textured implant collars are better suited for immediate loading and placement of dental implants.
