摘要： 目的： 比较自体块状骨移植与引导骨再生（guided bone regeneration,GBR）在水平骨增量中的临床效果。方法： 选择2019年6月—2021年6月于合肥市口腔医院行种植修复伴水平骨缺损的患者42例,随机分为2组。A组20例,采用自体块状骨移植;B组22例,采用GBR进行水平骨增量。评价2组患者并发症发生率、疼痛度、二次植骨率、骨宽度增量、骨吸收率、修复1年的边缘骨吸收量和种植成功率。采用SPSS 26.0软件包对数据进行统计学分析。结果： 2组种植成功率、并发症发生率和二次植骨率无显著差异,疼痛度A组显著高于B组（P<0.05）。术后6个月嵴顶下2 mm骨宽度增量A组显著高于B组（P<0.05）,而在嵴顶下6 mm和10 mm处,2组无显著差异;A组在嵴顶下2 mm吸收率显著低于B组（P<0.05）,在嵴顶下6 mm和10 mm处差异无统计学意义。2组修复1年后的边缘骨吸收量无显著差异。结论： 对于水平向骨缺损,自体块状骨移植较GBR在嵴顶处可获得更佳的骨轮廓,修复1年后2组边缘骨吸收量接近。

Abstract: PURPOSE: To compare the clinical efficacy of autologous bone block graft and guided bone regeneration (GBR) in horizontal bone augmentation. METHODS: A total of 42 patients were included and divided into two groups. Group A included 20 patients, in whom autologous bone block graft was performed. Group B included 22 patients, in whom GBR was conducted. The incidence of complications, pain degree, secondary bone graft rate, bone width increment, bone resorption rate, marginal bone resorption and implant success rate after 1 year of restoration were recorded and evaluated. SPSS 26.0 soft ware package was used for data analysis. RESULTS: There was no significant difference in implant success rate, incidence of complications and the rate of secondary bone grafting between the two groups. The pain degree in group A was significantly higher than that in group B(P<0.05). The increment of bone width at 2 mm below the crest in group A was more than that in group B(P<0.05). There was no significant difference in increment of bone width between 6 mm and 10 mm below the crest. The absorption rate of group A was significantly lower than that of group B at 2 mm below the crest(P<0.05), while the difference was not statistically significant at 6 mm and 10 mm below the crest. There was no significant difference in marginal bone resorption between the two groups 1 year after restoration. CONCLUSIONS: For horizontal bone defects, autologous bone block graft has a better bone contour at the crest than GBR. The amount of marginal bone resorption in two groups is similar after 1 year of restoration.
