Oral rehabilitation with dental implants is a common procedure in modern dentistry due to its high success rates. However, complications such as implant displacement can occur, particularly in the maxillary region due to factors like atrophied maxilla, thin alveolar bone, and low bone density. This case series explores scenarios of maxillary dental implant displacement, emphasizing the impact of immediate preoperative imaging on patient outcomes.
Three cases of maxillary implant displacement are presented, each illustrating a different scenario. Complications resulting from the displacement of implants into adjacent structures such as the maxillary sinus and nasal cavity are described. All cases involved implants that were displaced during second-stage surgery, occurring four to six months post-implantation. Removal attempts used transnasal endoscopic, intraoral, or combined approaches, with only one implant successfully retrieved. Delays in surgery ranged up to 72 h, leading to one implant being swallowed and another unlocated. Outcomes varied, with some patients requiring hospitalization for up to five days.
This series highlights the crucial role of immediate preoperative 3D imaging in precisely locating displaced implants to ensure their safe and efficient removal. While implant displacement may not always be preventable, optimizing the timeframe between diagnostic imaging and surgical intervention can significantly enhance management. Accurately locating the implant minimizes treatment invasiveness and patient discomfort, thereby improving clinical outcomes.
由于成功率高，口腔种植体的口腔修复是现代牙科中常见的程序。然而，由于上颌骨萎缩、牙槽骨薄、骨密度低等因素，种植体移位等并发症可能会发生，特别是在上颌区域。本病例系列探讨了上颌牙科种植体移位的情况，强调了术前即时成像对患者结果的影响。
呈现了三个上颌种植体移位的病例，每个病例都说明了不同的情况。描述了因种植体移位到上颌窦和鼻腔等相邻结构而引起的并发症。所有病例均涉及在植入物植入后四至六个月的第二期手术中移位的植入物。使用经鼻内窥镜、口内或联合方法进行了移除尝试，只有一个植入物成功取出。手术延迟最长达 72 小时，导致一个植入物被吞下，另一个未定位。结果各不相同，一些患者需要住院长达五天。
本系列强调了术前即时 3D 成像在精确定位移位种植体以确保其安全有效去除方面的关键作用。虽然种植体移位并非总是可以预防，但优化诊断成像和手术干预之间的时间框架可以显著改善管理。准确定位种植体可最大限度地减少治疗的侵入性和患者的不适，从而改善临床结果。
