The clinical study on reforming bone ring technique for alveolar bone augmentation
摘要
Abstract
Objective: To observe the effect of bone augmentation use Nano-hydroxyapatite collogen block as a bone ring at insufficient alveolar area, and to discuss the feasibility on clinical using. Methods: 10 patients intended to have an implant-supported prosthodontics, with missed teeth and insufficient alveo-lar ridge, were taken part in this research program after contradication excluded, and divided into two groups randomly. Group A, 5 cases in control group accept standard GBR treatment for ridge augmen-tation, add 1-2 metal anchor for space support;Group B, 5 cases in experimental group accept standard bone ring technique, using hydroxyapatite collogen block as a autogenous bone graft ,the block was fixed by metal anchor. All surgery area have been taken intraoral radiographs before surgery, immedi-ately after surgery and 6 months after surgery for regenerated bone level calculating, the data was treat-ed by paired t test for evaluating the effect of bone augmentaion. Results: The effect of bone augmen-tation was obtained at some degree in both group, within each group, there is significant difference on bone level before surgery and immediately after surgery, but no significant difference between before surgery and 6 months after surgery. In different groups, there was no significant difference among before surgery, immediately after surgery and 6 months after surgery. Conclusions: Within the observation pe-riod, the effect on bone augmentation using hydroxyapatite collogen block as a bone ring at insufficient alveolar area can not reach clinical requirement, but worth to further research on this field.关键词
