Purpose:
The purpose of this retrospective study was to determine the success of Brånemark System TiUnite implants (Nobel Biocare/Sweden) placed in partially or completely edentulous jaws restored with fixed or removable prostheses.
Patients And Methods:
A total of 131 jaws from 110 patients (64 maxillae and 67 mandibles) received 472 implants from July 2003 until March 2008. The patients included 57 men and 53 women, with a median age of 49.6 years and an age range of 16 to 90 years at the time of implant surgery. Twelve maxillae and 10 mandibles were completely edentulous, and 52 maxillae and 57 mandibles were partially edentulous. A single implant was placed in 21 jaws (10 maxillae and 11 mandibles), while multiple implants were placed in the other patients. Among the 131 jaws, removable prostheses were mounted in 10 maxillae and 8 mandibles, and the other jaws were restored with fixed prostheses.
Results:
Among the 472 implants, 6 maxillary implants and 5 mandibular implants were unsuccessful. The success rate for the implants was 96.56% (96.07% in the maxillae and 97.18% in the mandibles).
