Braenemark种植系统多牙基台的临床应用：37例报道

目的：评价Braenemark种植系统多牙基台用于连续多牙缺失种植修复的效果与优点。方法：对37例连续多牙缺失患者，常规l临床检查，曲面体层与根尖片分析，制作外科导板，应用常规种植外科手术方法植入117个Braenemark种植系统标准和MKⅢ种植体，3～6个月行二期手术后，应用多牙基台进行上部结构贵金属烤瓷桥体修复。结果：二期手术时有2个种植体松动、脱落，一期成功率98．29%。修复完成后随访12～24个月，2例患者3个种植体松动、脱落，其他112个种植体无脱落，也无明显种植体周围骨吸收，无基台及金柱螺丝松动，但有3个桥体小部分烤瓷崩瓷，二期成功率97．43%总成功率为95．7％。结论：多牙基台在集所有传统多牙修复基台的优点基础上进一步优化设计，不仅扩大了临床适用范围、简化了操作程序，而且增强了上部整体结构的性能，多牙基台较适合连续多牙缺失的种植修复，成功率高，且较传统多牙基台有一定优越性。

Application of Br?nemark system''s multi-unit abutment: report of 37 consecutive cases]

PURPOSE: To evaluate the short-term clinical effect and advantages of Br?nemark system's multi-unit abutment used for standard or MK III implants supported fixed prosthodontics. METHODS: Routine clinical examinations and preparations, including panoramic tomography, periapical radiograph and surgical guide plate, were performed in 37 cases with multiple lost teeth. A total of 117 Br?nemark system's implants were placed using a two-stage surgical approach. Multi-unit abutment connection was performed 3-6 months after implant installation. All superstructure prosthetic appliances were porcelain-fused-to-golden metal bridges. RESULTS: The follow-up period for the implants was 12 to 24 months. The total survival rate was 95.7%. Two implants were lost at second-stage surgery (the survival rate was 98.29% for first-stage), and 3 implants were lost after loading (the survival rate was 97.43% for second-stage). The other 112 implants function uneventfully. There were no bone loss around implants, no abutment and gold cylinder screw loosen. CONCLUSIONS: The multi-unit abutment, on basis of collecting all the merits of the traditional abutment, was further designed in a simplified way, which not only expands its clinical application, operate easily, but also enhance its whole superstructure. It is more suitable for implant supported fixed prosthodontics with high success rate and more advantages than the traditional abutment.
