ABSTRACT

Background: Implants design such as thread shape, thread pitch, thread depth and implant neck are considered to be important factor. The present study was conducted to assess effect of dental implants design on treatment outcome. Materials & Methods: The present retrospective study was conducted on 80 patients who received 150 dental implants. In all cases, implant design such as thread shape, thread pitch, thread depth and implant surface was recorded. Success or failure rate was assessed. Results: Out of 80 patients, males were 50 and females were 30. Males received 90 and females received 60 dental implants. Out of 150 dental implants, 25 had failures. Maximum implant failure was found in square shaped thread (10) followed by reverse buttress (8) and V- shaped (7). 0.7 mm threaded pitch implant had higher failure than 0.8 mm (9). Maximum failure rate was seen with anodized Surface (9) followed by machined (7), sandblasted surface (5) and acid etched surface (4). The difference was significant (P< 0.05). Conclusion: Authors found maximum dental implant failure with square shaped thread, 0.7 mm threaded pitch implant and implant with anodized surface.
