目的:评价膜引导骨再生术(GBR)在前牙区种植中的应用价值。方法:对22例前牙缺失患者按照牙槽骨唇舌向厚度不同分为两组,A组12例,牙槽嵴唇舌向厚度<6 mm,行GBR+牙种植术,B组10例,唇舌侧牙槽嵴厚度>6 mm,行牙种植术,通过临床和放射学检查对比分析种植术后半年、种植体负载1年后的牙槽骨的厚度及高度变化。结果:种植术后半年A组患者牙槽嵴唇舌向宽度较术前明显增宽(P<0.05),种植体负载1年后,A组患者与B组患者牙槽骨唇舌向及垂直向均有少量吸收,两组间无明显差异(P>0.05)。结论:对前牙区牙槽骨骨量不足的患者同期行GBR和种植体植入术效果好,可很好地解决骨组织不足的问题,可拓宽前牙区种植术的适应症。
Objective: To evaluate the value of membrane guided bone regeneration (GBR) in the cultivation of anterior teeth. Methods: Twenty-two cases of anterior teeth missing patients were divided into two groups according to the different thickness of alveolar bone and alveolar bone. Group A consisted of 12 cases with alveolar ridge-tongue thickness of <6 mm. GBR + dental implantation was performed. Group B, 10 cases, Alveolar ridge thickness> 6 mm, dental implant surgery, clinical and radiographic examination comparative analysis of six months after planting, implant 1 year after the alveolar bone thickness and height changes. Results: After 6 months of implantation, the alveolar width of the alveolar ridge in group A was significantly wider than that before operation (P <0.05). After implanting for 1 year, the alveolar width and vertical direction of alveolar bone in group A and group B A small amount of absorption, no significant difference between the two groups (P> 0.05). Conclusion: The effect of GBR and implant implantation on the alveolar bone in the anterior teeth area is good at the same time. It can solve the problem of insufficient bone tissue and broaden the indications of anterior dental planting.
