钛网结合无机牛骨在磨牙区种植同期垂直骨增量的应用

The applicafion of titanium mesh combined with anorganic bovine bone mined on alveolar bone vertical augmentation

目的:评价钛网+无机牛骨在磨牙缺牙区进行种植同期垂直骨增量的应用效果。方法:回顾2013年8月至2016年7月我院磨牙缺失伴骨缺损患者22例,分别用钛网(组1)或可吸收生物膜(组2)结合无机牛骨进行垂直向骨增量,共植入29枚种植体;应用CBCT影像测量患者术前、术后牙槽嵴垂直高度的变化,评价骨增量效果。结果:组1较组2术后牙槽嵴增加的平均高度有显著性差异(5.32±0.96) mm vs (3.87±0.86) mm,P<0.05;结论:钛网+无机牛骨可以有效的增加缺牙区牙槽嵴垂直骨高度,降低颌间距离。

Objective:To evaluate the effect of titanium mesh combination with anorganic bovin bone mined on vertical bone augmentation in the molar tooth region.Methods:22 patients with vertical bone defect in our hospital from August 2013 to July 2016 group 1 were treated with a titanium mesh in combination with anorganic bovin bone mined and a total of 22 implants were implanted.Group 2 using absorbable collagen membrane combination with anorganic bovin bone mined and a total of 7 implants were planted.To evaluate the effect of the bone augmentation,the changes in the vertical height of the aluvolar ridge were measured by the Cone-beam computed tomography image.Results:Comparison of alveolar ridge height between preoperative and postoperative,there was a significant difference between the two groups(5.32±0.96)mm vs(3.87±0.86)mm,P<005.Conclusion:Titanium mesh combined with anorganic bovin bone mined can more effectively increase the vertical bone height of alveolar ridge and reduce the distance between the jaws.It is helpful for the long-term stability of implant after restoration.
