A series of studies was begun in the mid-1980s in an effort to test the versatility of the osseointegration technique. One of these studies specifically tests the efficacy of single-implant support for crowns to replace missing single teeth. Thirty-two patients with 40 single-tooth spaces were treated with 40 implants, placed between 8 August 1985 and 21 June 1990. Twenty-eight were placed in the maxillae (27 in the anterior and 1 in the posterior zone). Twelve implants were placed in the mandible (all in the posterior zone). After loaded service periods ranging from 1.4 to 6.6 years (mean 2.9 years), all implants remain in function and have ensured successful prosthodontic treatment. These results suggest that the osseointegration technique can be adapted for use in patients with a missing single tooth with predictable good success.
20世纪80年代中期开始了一系列研究,以测试骨结合技术的通用性。其中一项研究专门测试了单个种植体支持牙冠替代单个缺失牙的疗效。1985年8月8日至1990年6月21日期间,对32例患者的40个单牙间隙植入了40颗种植体进行治疗。其中28颗植入上颌(27颗在前牙区,1颗在后牙区)。12颗植入下颌(均在后牙区)。经过1.4至6.6年(平均2.9年)的负载使用期后,所有种植体仍在发挥功能,并确保了成功的修复治疗。这些结果表明,骨结合技术可适用于单个牙齿缺失的患者,且成功率可预测。
