【摘要】：背景:膜引导骨再生技术是利用膜的机械屏障原理,阻挡软组织长入种植体周骨缺损,使成骨细胞在膜下空间中优势生长,形成新骨充填骨缺损。目的:于上前牙种植中应用引导骨再生技术,观察其对修复效果的影响。方法:74例单颗前牙种植成功患者按照随机数字表法分组为对照组与观察组,各37例。对照组采用上前牙二期种植,但未行骨增量;观察组采用引导骨再生技术实施上前牙种植,待其种植体初期稳定后植入人工骨粉。于术后当天、种植牙负重6个月、12个月比较2组患者软组织红色美学指数及种植体周围骨水平。结果与结论:2组患者种植牙负重6,12个月红色美学指数值较基线水平比较均明显提高(P0.05),但2组间比较差异无显著性意义(P0.05)。种植牙负重12个月时,除唇侧龈缘水平和牙槽突外形外,2组患者红色美学指数其余各项指数值较基线水平均明显升高(P0.05);但2组间红色美学指数各项指数值比较(P0.05)。种植牙负重12个月时,2组患者种植体边缘骨水平值比较差异无显著性意义(P0.05)。结果说明相比正常骨组织种植修复来说,临床应用引导骨再生技术于上前牙种植中修复可取得较好效果,且两者修复效果无明显差异性。
[Abstract]:Background: membrane guided bone regeneration is based on the principle of membrane mechanical barrier to prevent soft tissue from growing into peri-implant bone defects and to enable osteoblasts to grow preferentially in submembranous space. Objective: to apply the technique of guided bone regeneration in the implantation of anterior teeth. Methods 74 cases of successful implantation of single anterior teeth were divided into control group and observation group according to random digital table method. The control group was divided into two groups: the control group (n = 37) and the control group (n = 37). But no bone increment was observed. In the observation group, the anterior teeth were implanted with guided bone regeneration technique, and then artificial bone powder was implanted after the initial stabilization of the implant. On the day of operation, the implant teeth were loaded for 6 months. After 12 months, the soft tissue red esthetics index and bone level around implants were compared in two groups. Results and conclusion the weight of implant teeth in two groups was 6. 12 months red aesthetic index values were significantly higher than baseline level, but there was no significant difference between the two groups. With the exception of labial gingival margin level and alveolar shape, the other indexes of red aesthetic index in both groups were significantly higher than the baseline level (P 0.05). But the values of the red aesthetic index were compared between the two groups (P 0.05). The implant teeth were loaded for 12 months. There was no significant difference in the bone level between the two groups. The results showed that there was no significant difference between the two groups compared with the normal bone tissue implant repair. Clinical application of guided bone regeneration technique in the restoration of anterior teeth implant can achieve good results, and there is no significant difference between the two.
