BACKGROUND In the early 1980s, Brånemark described the use of cylindrical titanium dental implants integrated with bone. Since then, significant advances in dental implant technology have resulted in improved function and cosmetic appearance. This report describes an 87-year-old woman with a 31-year history of revision implant dentistry, initially for severe alveolar atrophy of the premolar and upper molar teeth. CASE REPORT In 1992, a severe alveolar atrophy of the upper premolar and molar areas was treated with the insertion of 4 fixtures in the frontal sector and a prosthesis superimposed anchored to the fixtures and with a rear support on the only surviving teeth. In 2004, the teeth were extracted and a distal support to the prosthesis was obtained with 2 fixtures in the maxillary tuberosity. In 2018, to eliminate the need for home removal of the prosthesis, 2 zygomatic fixtures were positioned and a fixed prosthesis was made. In 2023, at the last follow-up, satisfactory function and aesthetics of the prosthesis were reported and the bone levels at the fixtures appeared stable. CONCLUSIONS This report demonstrates the improvements in dental implant technology over more than 30 years in a single patient and highlights the importance of improved function and cosmetic appearance.
早在 20 世纪 80 年代，Brånemark 就描述了圆柱形钛牙科种植体与骨结合的应用。自那时以来，牙科种植体技术的显著进步带来了功能和美观的改善。本报告介绍了一位 87 岁女性，她有 31 年的修复种植牙病史，最初是因为前磨牙和上颌磨牙严重牙槽萎缩。
1992 年，采用在前额区域插入 4 个固定器并用固定器和仅存的牙齿上的后部支撑物叠加锚固的方法治疗上颌前磨牙和磨牙区域的严重牙槽萎缩。2004 年，这些牙齿被拔出，并在上颌结节处用 2 个固定器获得了对义齿的远端支撑。2018 年，为了消除义齿需要在家中去除的需要，放置了 2 个颧骨固定器并制作了固定义齿。2023 年，在最后一次随访时，报告了义齿的功能和美观令人满意，并且固定器处的骨水平看起来稳定。
本报告展示了 30 多年来在单个患者中牙科种植体技术的改进，并强调了功能和美观改善的重要性。
