Abstract: 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.
