Abstract

BACKGROUND:

Implant site preparation usually consists of several consecutive drilling steps, performed using different burs with increasing diameter.

PURPOSE:

The purpose of the present study was to report the clinical outcomes of edentulous patients that underwent implant treatment, in which a special bur that allows preparation of the implant site in a single drilling step was used.

MATERIAL AND METHODS:

One hundred forty-nine patients (79 males, 70 females, mean age 51.8 ± 12.2 [SD] years, range 20-80 years) have been rehabilitated using different oral surgery procedures. A total of 350 implants were inserted (171 in the maxilla and 179 in the mandible). A barrier membrane was used for covering a total of 126 implants. Fifteen implants were placed by using the osteotome technique and 52 by using the lateral sinus lift procedure. Eighty-nine implants were placed in postextraction sockets. Thirty-six implants underwent immediate loading. Implant survival, peri-implant bone level change, and patients' satisfaction were the main variables assessed.

RESULTS:

No patient dropout occurred. The mean follow-up on a patient basis was 21.5 ± 3.1 months (range 12-27 months). A total of seven implant failures were recorded in six patients, leading to a mean implant survival of 98.0% (96.0% on a patient basis). The mean peri-implant bone loss after 1 year was 0.58 ± 0.44 mm (n = 282). Apart from implant failures, no biological nor mechanical complications occurred. All patients demonstrated full satisfaction.

CONCLUSIONS:

The use of a single bur for implant site preparation allows the reduction of the time needed for the surgical procedure, without compromising the clinical outcomes. Further, long-term comparative studies are needed to confirm the results of this study.
