PURPOSE: This report presents the preliminary results of a prospective multicenter study to evaluate the efficacy of a chemically etched pure titanium surface on screw-type dental implants. MATERIAL AND METHODS: The results of 147 implants placed in 75 patients were evaluated and followed for up to 3 years, using clinical and radiographic examinations. The implants were inserted to support single crowns, overdentures, and fixed prostheses, as dictated by the individual patient's need. RESULTS: Of the 147 implants placed, 5 were lost and the remaining implants were followed throughout, to the end of the study period. Crestal bone levels adjacent to each implant were monitored and the amount of total bone loss was calculated. Clinically healthy peri-implant gingival tissues were observed on 95% of the implants, whereas 88.3% demonstrated no bleeding on probing and no recession during the follow-up period. According to the criteria used in this study, the total success rate was calculated to be 96.6%.
