Abstract：
This case report records the replacement of two failed endodontically treated mandibular molars with one piece zirconia implants in a patient with metal hypersensitivity. The two molars were atraumatically extracted and curetted to remove any remnants of a periapical granuloma. Immediate implant placement with primary stability was achieved using one piece WhiteSky® Bredent zirconia implants which were restored after four months with a zirconia crown. One year follow up revealed successful osseointegration with optimal form and function.
摘要：
此病例报告记录了在金属超敏反应患者中用一片氧化锆植入物替换两个失败的牙髓治疗的下颌磨牙。对两个磨牙进行无损伤提取并刮除以去除根尖周围肉芽肿的任何残留物。使用一片WhiteSky®Bredent氧化锆植入物实现具有主要稳定性的立即植入物放置，四个月后用氧化锆冠修复。一年的随访显示，成功的骨整合具有最佳的形式和功能。
