The aim of this paper is to report on three patients who received unconventional implant treatment because of the presence of impacted teeth. To avoid invasive surgical removal of the impacted teeth and delayed implant treatment, implants were placed through the impacted teeth. Of the seven implants placed into four impacted teeth, all healed uneventfully except a short (8.5-mm) implant that became mobile after 4 months. One and three implants now have been loaded for 3.5 and 2 years, respectively. The two other implants were removed after 6 months of uneventful healing. These cases, although limited in number, suggest that implant placement through an impacted tooth might not interfere with implant integration or harm occlusal function, at least in the short term. More study is warranted before this unconventional procedure might be considered as a possible clinical option when, at an impacted tooth site, clinicians seek to avoid invasive surgery.
本文旨在报告3例因存在阻生牙而接受非常规种植治疗的患者。为避免对阻生牙进行侵入性手术拔除以及延迟种植治疗,种植体通过阻生牙植入。在植入4颗阻生牙的7颗种植体中,除1颗短(8.5毫米)种植体在4个月后出现松动外,其余均顺利愈合。目前,分别有1颗和3颗种植体已负重3.5年和2年。另外2颗种植体在顺利愈合6个月后被取出。这些病例虽然数量有限,但表明通过阻生牙植入种植体可能不会干扰种植体的骨结合,也不会损害咬合功能,至少在短期内如此。在这种非常规手术被视为临床可行选择之前,即在阻生牙部位临床医生试图避免进行侵入性手术时,还需要进行更多的研究。
