Objective: The purpose of this study was to evaluate survival rate of Thai dental implant (PW PLUS®) which had been installed and restored in department of advanced general dentistry, Mahidol University (3-year results, from 2012-2015).
Materials and Methods: A retrospective documents review was conducted on 23 consecutive patients, 38 implants. Each patient had at least one implant placed in the maxilla and/or mandible in advanced general dentistry clinic, Mahidol University. These patients were recalled for examined in follow up visit. Patients were examined a clinical and radiographic assessment. All failed implant was recorded. Descriptive statistical analysis, implant survival were evaluated using Kaplan Meier analysis.
Results: 23 patients (11 were male and 12 were female) were included in this study. About 38 implants were placed, 1 implant failed due to fixture fracture, while 37 implant still in functioned. Biologic and mechanical complications were observed, screw loosening was 29.73% (11). A cumulative survival rate of 94.4% (37) was found after 3 years.
Conclusion: On the basis of this retrospective analysis it might be concluded that 3-year survival rate of Thai dental implant (PW PLUS®) was similar to others. Mechanical complications such as screw loosening appeared in high percentage.
