Abstract

The purpose of this case report was to present a rare clinical case of successful new dental implant installation in the site of previously healed medication-related osteonecrosis of the jaw (MRONJ). An 80-year-old female patient with history of oral bisphosphonate (BP) therapy presented with pain and swelling of gingiva in the right posterior mandible. One of the 3 implants placed 15 years ago in the right mandibular posterior area was removed 6 months before the visit to our hospital, which led to worsening of the symptoms. After clinical and radiographic examination, the patient was diagnosed with stage 2 MRONJ. Along with antibiotic therapy, the patient underwent surgical intervention via sequestrectomy and removal of the remaining 2 implants. Adequate soft and hard tissue healing without any complications and signs of recurrence was confirmed, and implant installation with simultaneous bone grafting and prosthesis fabrication were done in the explantation sites of MRONJ. By the 7-year follow-up, no implant failure has been observed, and installation of implants was successful in the previously healed MRONJ site. Dental implant installation is possible in a patient with history of failed implant due to MRONJ. However, a careful treatment planning is needed before implantation in a previously healed site of MRONJ to reduce the potential risks of MRONJ recurrence and implant failure.

下颌药物相关性骨坏死愈合部位成功植入新牙:1例报告。

本病例报告的目的是提出一个罕见的临床病例，成功的新牙种植体安装在先前愈合的颌骨药物相关性骨坏死(MRONJ)。80岁女性患者，有口服双膦酸盐(BP)治疗史，表现为右侧后下颌牙龈疼痛和肿胀。15年前在右下颌后区放置的3个种植体中，有一个在来我院前6个月被取出，导致症状恶化。经临床和影像学检查，患者被诊断为二期MRONJ。在抗生素治疗的同时，患者接受了手术干预，切除了剩余的2个植入物。确认软硬组织完全愈合，无任何并发症和复发迹象，在MRONJ外植体部位进行种植体安装，同时植骨和假体制作。在7年的随访中，没有观察到种植体失败，并且在先前愈合的MRONJ部位成功安装了种植体。由于MRONJ而有种植失败史的患者可以安装牙种植体。然而，在MRONJ先前愈合的部位植入之前，需要仔细的治疗计划，以减少MRONJ复发和植入失败的潜在风险。
