Abstract

PURPOSE
The purpose of present study was to retrospectively analyze the survival rate of implant placed after alveolar ridge preservation by initial stability and radiographic measurements.
MATERIALS AND METHODS
In total, 19 patients who received 21 sandblasted, large-grit, acid-etched (SLA) implants were enrolled in this retrospective study. Implants placed after alveolar ridge preservation technique (ARP) 2 - 3 months healing period, Periotest value (PTV) measured at implant placement and before placed prosthodontics. Marginal bone level (MBL) was measured at implant placement and final recall check.
RESULTS
Overall survival rate of implant was 100%. Mean PTV at implant placement was −0.06 ± 8.33 and mean PTV before placed prosthodontics was −5.75 ± 1.72. The range of MBL change was from −0.55 mm to 1.6 mm (Mean: 0.19 ± 0.58 mm).
CONCLUSION
The findings of present study suggest that the implant paced after alveolar ridge preservation appear high survival rates and stable MBL.
