Abstract
Failure rates at second-stage surgery were reported for the ongoing Dental Implant Clinical Research Group studies of the Spectra-System (Core-Vent Corporation, Las Vegas, NV) implants. As of May 1995, 69 implants failed out of 2,633 placed and uncovered. The overall failure rate was 2.6%, with 3.6% in bone quality 1 (BQ-1), 2.4% in BQ-2, 2.5% in BQ-3, and 3.1% in BQ-4. HA-coated cylinders had the lowest number of failures and titanium alloy baskets the highest. The basket design failed more often in the posterior jaw areas; 9 of 32 clinical centers (28%) accounted for 72% of these failures.
