Wide diameter implants may be a useful alternative to conventional implant rehabilitation. Despite the fact that most major implant manufacturers are supplying wide diameter implants, very few articles actually address the indications, benefits and results of the use of wide diameter implants. Benefits and indications include increased implant surface area, "back-up" implant for when the initial implant lacks stability, immediate replacement of non-integrated or fractured implants, immediate placement of an implant after tooth extraction, anatomical considerations, increased prosthetic stability and biomechanical factors. Over a two year period, 268 wide diameter implants were placed in 196 patients. Preliminary results are presented in this paper and indicate an overall success rate, up to two years after placement, of approximately 96 per cent. All failures occurred before stage two surgery, due to non-integration of the implant.
大直径种植体可能是传统种植修复的一种有用替代方案。尽管大多数主要种植体制造商都在供应大直径种植体,但实际上很少有文章真正探讨使用大直径种植体的适应证、益处和效果。其益处和适应证包括增加种植体表面积、当初始种植体缺乏稳定性时作为“备用”种植体、即刻替换未整合或折断的种植体、拔牙后即刻种植、解剖学考虑因素、增加修复体稳定性以及生物力学因素。在两年时间里,为196例患者植入了268颗大直径种植体。本文展示了初步结果,表明种植体植入后长达两年的总体成功率约为96%。所有失败病例均发生在二期手术前,原因是种植体未整合。
