自1994年以来，有15例腭裂患者在采用骨成形术治疗牙槽裂后接受了种植牙。共进行了23颗种植体，其中12颗种植体在第三期成形术后种植，7颗种植体同时进行了重复成形术，另外4颗种植体在两期再成形术后种植。对11例患者共17例种植体进行了临床和影像学随访。在每个种植体上构建一个单独的冠。放射学评估显示70%的植入物完全嵌入骨内。除一个外，所有植入物均保持原位稳定。因此，成功率为96%。一般认为，牙槽裂的种植体可能由于其位置不佳，稳定性和功能不佳或种植得太晚而丢失。以前手术留下的疤痕也会导致植入物的失败。因此，建议牙种植体不应在牙槽裂成形术后6至8周内植入。(C) 1999欧洲颅颌面外科协会。
Since 1994, 15 cleft patients have received dental implants after treatment of the alveolar clefts by osteoplastic measures. Altogether 23 dental implants were undertaken, Twelve implants were inserted after tertiary osteoplasty, 7 with simultaneous repeat-osteoplasty, and another 4 implants following two-stage re-osteoplasty. In 11 patients with a total of 17 implants clinical and radiological follow-ups were performed. An individual crown was constructed on each of the implants. The radiological evaluation revealed that 70% of the implants were fully embedded in bone. All implants except one remained in situ and stable. Thus, the success rate was 96% retention. It is believed that a dental implant in the alveolar cleft mag be lost because of its unfavourable location in terms of stability and function or because it was inserted too late. Scars resulting from previous surgery can also play a role in the failure of an implant. Therefore it is proposed that dental implants should not be inserted later than 6 to 8 weeks following osteoplasty of the cleft alveolus.
