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.
40例连续性下颌牙槽嵴萎缩患者，采用带球帽附着体的非潜入式中空ITI-Bonefit牙科种植体支持覆盖义齿，作为联合前庭-舌侧成形术加游离中厚皮片移植及可摘义齿的替代治疗方法。共植入156枚非潜入式种植体。球帽附着体安装在种植体上，种植体植入后3 - 4个月插入种植体支持的覆盖义齿。种植体激活及义齿插入后的观察期为1至3年，中位观察期为2年。单个种植体的总体成功率为99%（155/156）。义齿功能率为100%（40/40）。单个种植体1年成功率为99%（155/156），义齿功能率为100%（40/40）。未观察到持续性手术、牙周或修复并发症。结果表明，带球帽附着体的非潜入式骨结合ITI-Bonefit牙科种植体支持覆盖义齿可成功替代联合前庭-舌侧成形术加游离中厚皮片移植及可摘义齿，与使用潜入式牙科种植体一样成功。
