对66名单个前牙缺失患者共植入79颗叶状种植体,随访观察时间最长5年,最短为2年。按瑞典Albrektsson的评价标准,成功率97.5%(77颗),失败率2.5%(2颗),并对此进行了分析。其目的是探讨叶状种植体,在单个前牙缺失种植应用和对术后立即用光敏复合树脂把两侧健康牙的邻面和基桩粘接成三位一体的美观而稳固的临时冠,用以保护种植体在骨内形成骨整合的探讨。 Sixty-seven single anterior teeth missing patients were implanted with 79 leaf-shaped implants. The longest follow-up was 5 years and the shortest was 2 years. According to the evaluation criteria of Sweden's Albrektsson, the success rate was 97.5% (77) and the failure rate was 2.5% (2), and this was analyzed. The purpose of this study was to investigate the use of leaf-shaped implants in the implantation of a single anterior tooth defect implant and the use of a light-sensitive composite resin immediately after surgery to bond the proximal and base piles of healthy teeth on both sides to a trinity, Protection of implant in the formation of bone in the integration of bone.
