A socket is carefully drilled at the exact location for the replacement tooth, a dental implant in then placed into the socket. If a tooth is being replaced the implant can often be placed on the same day as the removal of a tooth.
Implants either come with a screw-thread on the outer surface or without. Dental implants with a screw-thread are screwed into position, those without are usually tapped into place. The main aim during placement of either type of implant is to achieve immediate close contact with the surrounding (jaw) bone. This closeness provides intial stability which over time will steadily increase by further growth of the surrounding bone into the microscopic rough surface.
