文摘目的分析种植区GBR手术同时填加血小板浓缩物-浓缩生长因子(concentrated growth factors,CGF)对成骨时间影响。方法选取本科室2017年1月—2018年12月收治骨量不足的牙体缺失患者60例,采用双盲分组法将其分成常规组及联合组,每组30例,分别接受单纯引导骨组织再生术(guided bone regeneration,GBR)治疗、GBR联合血小板浓缩物-浓缩生长因子(CGF)治疗。比较两组患者骨密度、缺损再生及成骨时间、疼痛程度、临床疗效。结果术前两组患者骨密度比较差异无统计学意义(P>0.05),术后增高;其中联合组患者术后1个月、3个月、6个月骨密度高于常规组,差异有统计学意义(P<0.05)。联合组骨痂及骨性连接形成时间少于常规组,差异有统计学意义(P<0.05),植骨高度、成骨厚度高于常规组,差异有统计学意义(P<0.05)。常规组及联合组患者疼痛程度差异比较无统计学意义(P>0.05)。常规组及联合组患者临床疗效比较差异有统计学意义(P<0.05)。结论GBR联合CGF治疗骨量不足的牙体缺失能明显提升临床疗效,减少成骨时间,不增加手术疼痛,促进缺损再生。
