Clin Oral Implants Res:BMP-2异体骨块与自体骨进行骨增量后种植修复的效果相当

种植修复逐渐成为缺失牙的主要修复手段,对于牙槽骨骨量不足的患者,多需要进行骨增量。近日,研究人员评估了使用BMP-2的异体骨块或自体骨块进行种植区骨增量,种植体存活率和三维边缘软组织轮廓方面的结果。

种植修复逐渐成为缺失牙的主要修复手段,对于牙槽骨骨量不足的患者,多需要进行骨增量。近日,研究人员评估了使用BMP-2的异体骨块或自体骨块进行种植区骨增量,种植体存活率和三维边缘软组织轮廓方面的结果,研究已发表于Clin Oral Implants Res

研究纳入24名牙槽嵴宽度不足,需要进行初次骨增量的患者,随机分配到添加rhBMP-2的脱蛋白牛骨矿块(BMP)组或口内采集的自体骨块(ABB)组。骨增量手术后4个月,在再生区植入1-4颗种植体。在牙冠戴入后即刻和负荷后3年,评估了种植体周围组织参数、二维和三维放射学参数以及软组织轮廓变化。此外,研究人员还进行了探索性的混合模型分析。显著性水平被设定为5%

 

结果,在3年的随访中,研究人员对23名患者的40颗种植体进行了评估。分析结果显示,两组的种植体存活率都是100%。基线时,BMP组的边缘硬组织水平为-0.4±0.8毫米(平均值±标准差),ABB组为-0.7±1.0毫米(平均值±标准差)。3年后,BMP组的边缘硬组织水平为-0.2 ± 0.4 mm(平均值±标准差),ABB组为-0.6 ± 1.0 mm(平均值±标准差)。基线时,种植体颈部的硬组织厚度为1.1±1.1毫米(BMP)和1.4±1.0毫米(ABB)。3年后,其厚度为0.9 ± 0.9 mmBMP)和0.7 ± 0.6 mmABB)。

 

综上所述,该研究结果表明,在牙冠戴入3年后,两组种植体的存活率都很好,硬组织边缘水平稳定。此外,两组的软、硬组织的临床稳定性都得到了证实。
