【摘要】：背景:将短种植体应用于后牙区单颗牙缺失修复,临床上已有较多应用,当上下颌缺牙数较多时,将短种植体应用于种植固定桥的效果如何?目的:观察种植双端固定桥采用短种植体修复的效果。方法:选择43例后牙区多牙缺失患者,其中男26例,女17例,年龄44-67岁,均采用短种植体进行双端固定桥修复,种植体植入后2年,随访观察种植体成功率、牙槽嵴骨吸收量及种植体并发症。结果与结论:共植入92枚短种植体,其中上颌植入44枚,下颌植入48枚,种植体长度介于6-8 mm之间;2枚种植体发生种植体周围炎,种植体2年成功率为97.8%;植入后1,2年,种植体长度8 mm组、种植体长度7 mm组、种植体长度6 mm组间骨吸收量无差异;植入后1,2年,冠根比≤1组、1冠根比≤2组、冠根比2组间骨吸收量无差异;修复后出现烤瓷冠中央螺丝松动4例,烤瓷冠崩瓷1例。结果表明,短种植体应用于双端固定桥修复短期内取得了较大成功,长期效果仍需观察。
[Abstract]:Background: when short implants are applied to the restoration of single tooth loss in the posterior region, there have been more clinical applications. When there are more teeth missing in the upper mandible, what is the effect of applying short implants to the implant fixation bridge? Objective: to observe the effect of short implant on two-end implant fixed bridge. Methods: Forty-three patients (26 males and 17 females aged from 44 to 67 years old) with multiple teeth missing in posterior teeth were treated with short implants and treated with double end fixed bridge. The success rate of implants was observed after 2 years of implantation. Alveolar ridge resorption and implant complications. Results and conclusion: 92 short implants were implanted, including 44 maxillary implants and 48 mandibular implants, the length of implants ranged from 6 to 8 mm, 2 implants had peri-implant inflammation, the success rate of implant was 97.8%. There was no difference in bone resorption between implant length of 6 mm group and implant length 8 mm group (1, 2 years after implantation), but there was no difference in bone resorption amount between crown root ratio 鈮，
