AIM
The aim of this research was to assess peri-implant bone remodeling of post-extractive implants over 2 years.
MATERIAL AND METHODS
30 patients meeting pre-established inclusion criteria were enrolled for the study. One implant for each patient was inserted in the post-extraction sockets according to a defined surgical protocol (atramautic extraction, curettage of extraction socket, implant insertion, grafting with collagenated cortico-cancellous porcine bone, and a trimmed collagen membrane to completely cover the socket, suture). A temporary adhesive bridge, with an adequate profile, was bonded to the adjacent teeth. X-ray evaluation with a standardized stent was carried out at different times. Measurements were obtained from the implant edge to the bone peak. The values obtained at time 0 and at 2 years were compared by t-student test.
RESULT
Our results showed that after one year 73% of patient had 0 mm of bone reabsorption, 20% of patient had 0 mm ≤ x ≤ 0.5mm, 7% of patient had 0.5 mm ≤ x ≤ 2 mm of bone reabsorption. After two years 62% of patient had 0 mm of bone reabsorption, 24% had 0 mm ≤ x ≤ 0.5mm, 14% had 0.5 mm ≤ x ≤ 2 mm.
CONCLUSIONS
The results showed no significant differences in bone reabsorption in most patients over 2 years.
目的
本研究的目的是评估拔牙后种植体在2年时间内的种植体周围骨重塑情况。
材料与方法
30名符合既定纳入标准的患者被纳入本研究。按照既定的手术方案（无创拔牙、刮治拔牙窝、植入种植体、用猪皮质松质骨胶原骨移植、修剪胶原膜以完全覆盖拔牙窝、缝合），为每位患者在拔牙窝中植入一枚种植体。将一枚外形合适的临时粘结桥粘结到相邻牙齿上。在不同时间使用标准化定位架进行X线评估。测量从种植体边缘到骨嵴顶的距离。通过t检验比较在0时和2年时获得的值。
结果
我们的结果显示，1年后，73%的患者骨吸收为0mm，20%的患者骨吸收为0mm≤x≤0.5mm，7%的患者骨吸收为0.5mm≤x≤2mm。2年后，62%的患者骨吸收为0mm，24%的患者骨吸收为0mm≤x≤0.5mm，14%的患者骨吸收为0.5mm≤x≤2mm。
结论
结果显示，大多数患者在2年时间内骨吸收无显著差异。
