Abstract
- Objectives: In contrast to the excellent long-term outcomes described for implant-supported mandibular overdentures, less favorable long-term survival and success rates have been reported for maxillary implants supporting overdentures. The aim of this study was to evaluate the treatment outcome of 'planned' bar-retained maxillary and mandibular overdentures supported by Morse taper connection implants, investigating implant survival, peri-implant tissue health, marginal bone resorption and prosthetic complications. Material and methods: Over a 2-year period, 60 patients were enrolled in this study, in four different clinical centers. The overdentures (maxilla 38, mandible 34) were planned with support from four implants anchored on a bar. A total of 288 Morse taper connection implants (Leone Implant System<superscript>®</superscript>) were inserted (152 maxilla, 136 mandible). Implants were evaluated 5 years after insertion. Success criteria included the absence of pain, suppuration or clinical mobility, the distance between implant shoulder and first crestal bone-implant contact (DIB) <2 mm and no exudate history. Results: The overall 5-year implant survival rate was 98% (maxilla 97.4%, mandible 98.6%), with 282 implants still in function. Among these surviving implants, 278 (98.6%) were classified in the success group. At the 5-year examination, the mean DIB was 0.7 mm (±0.53). Few prosthetic complications were reported. Conclusions: With 'planned' bar-retained maxillary and mandibular overdentures supported by Morse taper connection implants, satisfactory survival and success rate can be achieved.
