文题释义:
短种植体
:临床上将长度小于10 mm的种植体称为短种植体。目前Straumann公司已有4 mm长度的短种植体可供临床选择。
冠根比C/I值:传统修复学理论认为, 保持与天然牙接近的冠根比例才能维持修复体的长期稳定。早期的种植理念遵循传统修复学理论,认为剩余牙槽骨的高度应大于10 mm,才能获得与天然牙接近的冠根比C/I值。临床冠根比指修复体顶端至骨-种植体界面的高度/种植体末端至骨-种植体界面的高度。解剖冠根比指修复体顶端至修复体-基台界面的高度/种植体末端至修复体-基台界面的高度。

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: Short dental implants have been widely used in the posterior area when one tooth loses. How effective is it when we use the short implants in the rigid fixed bridge for the multiple teeth lost area?
OBJECTIVE: To observe the clinical effect of short dental implants used in the rigid fixed bridge.
METHODS: Forty-three patients with multiple missing teeth were enrolled and underwent the rigid fixed bridge supported by short dental implants, including 26 males and 17 females, with an age range of 44-67 years. After 2 years of dental implantation, the success rate of dental implants, amount of alveolar bone loss and dental implant-related complication were followed up.
RESULTS AND CONCLUSION: A total of 92 short dental implants, 6-8 mm in length, were implanted, ncluding 44 in the maxilla and 48 in the mandible. There were two cases of peri-implantitis and the success rate of implants was 97.8%. There was no significant difference in the amount of alveolar bone loss between the    8 mm, 7 mm and 6 mm length implants as well as between the C/I ≤ 1, 1 < C/I ≤2, C/I > 2 groups at 1-2 years after implantation. There were four cases of central screw loose and one case of porcelain fracture after restoration. To conclude, the clinical use of short dental implants in the rigid fixed bridge has achieved good outcomes during the short period, but long-term observation is needed.
