Seven patients who had previously received mandibular endosseous implants sustained mandibular fractures and were treated. Three patients had advanced bone resorption and developed stress fractures through previous endosseous implant sites. Two patients sustained fractures through implant sites via trauma. Two patients sustained fractures anatomically separated from the implants, which caused an alteration in the dental occlusion. This report describes the treatment approach for these seven patients and reviews the treatment philosophy and procedures involved. A conservative treatment approach is advised when the fracture transverses through a stable or a recently failed implant site.
7名先前接受过下颌骨内种植体植入的患者发生了下颌骨骨折并接受了治疗。3名患者出现了严重的骨吸收，并通过先前的骨内种植体部位发生了应力性骨折。2名患者因外伤通过种植体部位发生骨折。2名患者发生的骨折在解剖位置上与种植体分离，导致牙合关系改变。本报告描述了这7名患者的治疗方法，并回顾了所涉及的治疗理念和程序。当骨折横穿过稳定或近期失败的种植体部位时，建议采用保守治疗方法。
