Brånemark dental implants with ball attachments supporting overdentures were used as alternative treatment to combined lingual-vestibuloplasty with free split-thickness skin graft and removable dentures in 25 consecutive patients with mandibular alveolar ridge atrophy. Ninety-three fixtures were placed. Ball attachments were mounted on the fixtures, and implant-supported overdentures were inserted 3 to 4 months after fixture placement. The observation period after implant activation and prosthesis insertion varied from 12 to 27 months with a median observation period of 18 months. The overall success rate of individual implants was 97% (90/93). The prosthesis function rate was 100% (25/25). The 1-year success rate of individual implants was 98% (91/93) with a prosthesis function rate of 100% (25/25). No persistent surgical or prosthodontic complications were observed. Preliminary results indicate that osseointegrated Brånemark dental implants with ball attachments supporting overdentures can be a successful alternative to combined lingual-vestibuloplasty with free split-thickness skin graft and removal dentures in patients with denture problems related to mandibular alveolar ridge atrophy.
在连续25例下颌牙槽嵴萎缩患者中，采用带有球帽附着体支持覆盖义齿的Brånemark种植牙作为联合舌-前庭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93枚种植体。在种植体上安装球帽附着体，并在种植体植入3至4个月后戴入种植体支持的覆盖义齿。种植体激活和义齿戴入后的观察期为12至27个月，中位观察期为18个月。单个种植体的总体成功率为97%（90/93）。义齿功能率为100%（25/25）。单个种植体的1年成功率为98%（91/93），义齿功能率为100%（25/25）。未观察到持续性的手术或修复并发症。初步结果表明，对于与下颌牙槽嵴萎缩相关的义齿问题患者，带有球帽附着体支持覆盖义齿的骨结合式Brånemark种植牙可作为联合舌-前庭成形术加游离中厚皮片移植及可摘义齿的一种成功替代方法。
