与牙科植入物相关的并发症的数量一直在增加，因为种植体治疗已经成为替换缺失牙齿的最受欢迎的治疗选择。已经报告了各种植入物并发症的病例，特别是由不适当的手术技术引起的生物学并发症，包括植入物错位，这些都是难以解决的。在本病例中，一位64岁的女性患者的上颌右侧第一磨牙区域放置了两个错位的种植体并伴有种植体周围炎。为了治疗种植体周围感染并促进自身斑块控制，取出了一个错位的种植体，另一个使用掺铒钇铝石榴石（Er：YAG）激光进行了开放皮瓣清创术。然后适当改变种植体上部结构以恢复口腔功能。本病例报告展示了种植体错位引起的种植体周围炎的临床步骤、愈合过程和6个月随访。
The number of complications related to dental implants has been increasing, as implant therapy has grown to become the most popular treatment choice for replacing missing teeth. Various cases of implant complications have been reported, particularly biologic complications caused by inadequate surgical techniques, including malpositioned implants, that are difficult to solve. In the present case, two malpositioned implants with peri-implantitis were placed in the maxillary right first molar area of a 64-year-old woman. To treat the peri-implant infection and facilitate self--plaque control, one malpositioned implant was removed, and the other was treated with open flap debridement using an erbium-doped yttrium aluminum garnet (Er: YAG) laser. The implant suprastructure was then changed adequately to recover oral function. This case report demonstrates the clinical steps, healing process, and 6-month follow-up of peri-implantitis caused by malpositioned implants.
