Purpose: The aim of the present study was to evaluate the clinical outcome of new tapered design implants installed in maxillary posterior areas.
Materials and Methods: From Jun 2011 through October 2012, 17 patients (14 men, 3 women) treated with tapered implants (Osstem TS IV) were considered. Thirty-eight implants (6 premolar and 32 molar) were placed in maxillary posterior areas. Implant stability and crestal bone loss were measured.
Results: The implant stability quotient value was 59.9 at implant placement and 70.5 at the second surgery, indicating a significant difference. Mean crestal bone loss was 0.15±0.15 mm (no sinus elevation group: 0.10±0.13 mm; sinus elevation and simultaneous group: 0.16±0.15 mm; sinus elevation and delayed group: 0.20±0.19 mm). There was no significant difference according to sinus elevation or between the simultaneous group and delayed group. The success rate was 97.4%, and the survival rate was 97.4%.
Conclusion: New tapered design implants should be applied to maxillary posterior areas.
