title: Non-submerged osseointegrated dental implants with ball attachments supporting overdentures in patients with mandibular alveolar ridge atrophy. A short-term follow-up.
abstract: Non-submerged, hollow screw ITI-Bonefit dental implants with ball attachments supporting overdentures were used as alternative treatment to combined vestibulo-lingual-plasty with free split-thickness skin graft and removable dentures in 40 consecutive patients with mandibular alveolar ridge atrophy. One hundred and fifty-six non-sub-merged fixtures were installed. Ball attachments were mounted on the fixtures and implant-supported overdentures inserted 3-4 months after fixture installation. The observation period after implant activation and prosthesis insertion varied from 1 to 3 years with a median observation period of 2 years. The overall success rate of individual implants was 99%(155/156). The prosthesis function rate was 100%(40/40). The 1-year success rate of individual implants was 99%(155/156) with a prosthesis function rate of 100%(40/40). No persistent surgical, periodontic or prosthodontic complications were observed. The results indicate that non-submerged osseointegrated ITI-Bonefit dental implants with ball attachments supporting overdentures can be a successful alternative to combined vestibulo-lingual-plasty with free split-thickness skin graft and removable dentures, and as successful as the use of submerged dental implants.
