Abstract

The locking taper abutment attachment for implants is a one and one-half-degree tapered post that relies on friction rather than a screw for retention of the abutment to the implant. A retrospective analysis of 1,757 consecutively loaded implants was made to determine the reliability of the locking taper abutment. Five hundred and four implants restored over a 7-year period from one practice and a total of 1,253 implants restored over 4 years from 2 practices were reviewed. Nine abutment posts fractured for a failure rate of 0.05 percent. Thirty one (1.7 percent) of the abutments loosened but were reinserted without further problems. The technique for use of the locking taper implant abutment attachment is described.
