摘要:

背景:种植体的初期稳定性是影响种植体成败的关键因素,提高种植体在骨质不佳的植入床中的初期稳定性可以提高种植体的成功率。
目的:通过建立体外松质骨的骨块模型,模拟临床牙种植体植入,采用骨挤压术和传统备洞术在新鲜离体骨块上植入种植体,观察不同种植方法对种植体初期稳定性的影响。
方法:从新鲜的猪肩胛嵴处截取骨段,制成10 mm×10 mm×10 mm的新鲜立方形骨块(12块),固定后用骨挤压术和传统备洞术植入相同规格相同型号的BEGO种植体,分别记录种植体初期稳定性,并对观察结果进行t检验分析。
结果与结论:与传统备洞技术相比,在种植手术中采用骨挤压方法获得的种植体初期稳定性较高(P < 0.05)。提示骨挤压技术可以为种植体提供更好的初期稳定性。

Abstract:

BACKGROUND: Primary stability of implants is the key factor to the success of implantation, and improving primary stability can raise the rate of successful implantation when bone quality is poor in implant region.
OBJECTIVE: Through the establishment of the cancellous bone model to simulate the clinical dental implant surgery, to measure the primary stability of the implant so as to assess the bone extrusion operation effect as compared with the traditional hole prepared surgery.
METHODS: Bone segments from the crest of scapular spine of fresh pigs were made into cuboid bone blocks (n=12) of 10 mm×10 mm×10 mm. After fixation, bone extrusion operation and traditional hole prepared surgery were performed to implant BEGO implants with the same specifications and the same type. Primary stability of implants was recorded, and t test was performed.
RESULTS AND CONCLUSION: Compared with the traditional hole prepared surgery, a better primary stability for the implant was obtained following bone extrusion operation (P < 0.05), indicating that bone extrusion operation is better for primary stability of implants.
