自1989年8月以来，连续35例患者接受即刻种植体治疗，以取代50颗因牙根骨折、牙髓不稳定、不可修复的龋损或牙周病而需要拔除的牙齿。对与种植体相关的缺损进行形态学分组，并使用脱钙冻干粉碎松质骨（DFDBA）、e-PTFE膜或两者进行骨再生处理。螺纹暴露最初范围为4至20个螺纹，而种植体长度范围为8.5至18 mm。平均种植体长度为15 mm，平均螺纹暴露为11.34个螺纹，或种植体螺纹长度的54%。在仅用DFDBA治疗的无壁组中，除一个种植体外，所有种植体的再进入证实了100%的螺纹覆盖。三例组织学评价证实了再生骨的活力。患者随访至1993年4月，49个种植体（98%）保持骨整合和功能，支持即刻种植体植入的可预测性。患者的年龄范围为16 - 80岁，因此还讨论了与青少年相关的种植体放置注意事项。
Since August 1989, 35 consecutive patients were treated with immediate implants to replace 50 teeth requiring extractions as a result of root fractures, endodontic instability, nonrestorable carious lesions, or periodontal disease. Defects relative to the implant were morphologically grouped and were treated for bone regeneration with demineralized freeze-dried crushed cancellous bone (DFDBA), e-PTFE membrane, or both. Thread exposure initially ranged from 4 to 20 threads, while implant lengths varied from 8.5 to 18 mm. The mean implant length was 15 mm, with mean thread exposure of 11.34 threads, or 54% of the threaded length of the implant. Reentry confirmed 100% thread coverage in all but one implant in the no-wall group treated with DFDBA alone. Histologic evaluation of three cases confirmed viability of the regenerated bone. The patients were followed through April 1993, with 49 implants (98%) remaining osseointegrated and functional, supporting the predictability of immediate implant placement. The age of the patients ranged from 16 to 80 years, hence implant placement considerations relative to adolescents are also discussed.
