Abstract

PURPOSE:

Placement of small-diameter implants often provides a solution to space-related problems in implant restoration. This 7-year retrospective study presents results from 192 small-diameter implants placed in 165 patients from 1992 to 1996.

MATERIALS AND METHODS:

The dental records of each patient were reviewed. The implants, which were either 2.9 mm or 3.25 mm in diameter, were placed by 2 different surgeons. All prosthetic appliances were fabricated by the same prosthodontist. Ninety-four implants supported single-tooth cemented restorations; the remaining 98 implants supported cemented or screw-retained partial prostheses.

RESULTS:

The total implant survival rate was 95.3%. Four implants were lost at second-stage surgery, and 5 more were lost after loading.

DISCUSSION:

Small-diameter implants demonstrated a survival rate similar to those reported in previous studies of standard-size implants.

CONCLUSIONS:

The results suggest that small-diameter implants can be successfully included in implant treatment. They may be preferable in cases where space is limited.
