A 3 year-retrospective study of survival rate in single Branemark TiUnite(TM) implant / 대한치주과학회지

ABSTRACT

BACKGROUND: TiUnite(TM) is a highly crystalline and phosphate enriched titanium oxide surface which has a unique porous surface structure. This improved implant surface enhances bone response and reduces healing period. It also assures early stability of implant. These help to increase the success of implant. The aim o f this s tudy i s to e valuate the survival r ate of TiUnite TM surfaced single implant. MATERIALS AND METHODS: A retrospective analysis of 89 TiUnite(TM) surfaced implants replacing a single tooth was assessed according to their dental record. The age of the patients ranged from 17 to 82 years (mean age 45.8 +/- 14.6). Data were recorded regarding the survival rate of these implants. RESULTS: Fifty-two implants (57%) were placed in the maxilla, and 37 (43%) in the mandible. Over 75% were placed in the posterior area. Of the placed implants, 67% were the wide type, while 25% were the regular type and only 8% were of the narrow type. The single implants produced an overall clinical survival rate of 96.6% over the observation period (mean 17.9 months). Among 89 implants, only 2 implants were removed and one implant was submerged. CONCLUSION: According to t he se data, TiUnite(TM) surfaced implant in a single tooth restoration showed favorable survival rate although this study was done in a short term period.
