Clinical evaluation of small-diameter implants in single-tooth and multiple-implant restorations: a 7-year retrospective study.
OBJECTIVE
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.


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.


CONCLUSIONS
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.
