Abstract
Purpose: The present study examined the long-term prognosis after the complete restoration of edentulous patients with implants.
Materials and Methods: The implant restorations were divided into three groups (implant-supported fixed prosthesis, implant-supported hybrid prosthesis and implant-supported overdenture). From May 2005 until July 2014, 52 patients who received full treatment for edentulous sites (Male 27, Female 25) at Seoul National University Bundang Hospital were enrolled in this study. A total of 431 implants were insatlled, and the complications were evaluated. In addition, marginal bone loss around the implants was measured by a radiographic evaluation. Based on this type of prosthesis and the placement position (maxilla and mandible), success rate, and survival rate of the implants were evaluated.
Results: The mean marginal bone loss was 0.74±0.55 mm (complete fixed prosthesis), 0.49±0.56 mm hybrid hybrid prosthesis, 0.52±0.57 mm (implant-supported overdentures. In fixed prosthesis type, there was no statistically significant between sex, anatomical location, and bone graft. In hybrid fixed prosthesis type, anterior position was 0.58±0.46 mm and posterior area was 0.38±0.44 mm. Angulated Implant’s marginal bone loss was 0.39±0.55 mm and uprighting implant’s marginal bone loss was 0.63±0.67 mm. Total implant survival rate was 94.8%. 22 implants were removed because of osseointegration failure. 17 implants were not consistent with the success criteria. In conclusion, the success rate of three groups (implant-supported fixed prosthesis, implant-supported hybrid dentures and implant-supported overdenture) was 89.3%, 92.0%, 93.1%, respectively.
Conclusions: An average of eight years and six months of assessment of fully edentulous patients with implant estorations revealed satisfactory results.
