摘　　要：目的:探讨牙槽突扩张术联合骨引导再生(GBR)植骨术同期种植牙在牙齿发育异常患者中的应用效果。方法:纳入87例(94牙)牙齿发育异常患者为研究对象,根据治疗方式不同分为常规组(n=37,40牙)和GBR组(n=50,54牙)。常规组行牙槽骨劈开术治疗;GBR组行牙槽突扩张术联合GBR植骨术治疗,术后随访1年。比较两组患者治疗有效率、手术基本情况(手术时间、离院时间及骨愈合时间);术后1个月及6个月种植体稳定性[稳定系数(ISQ)];术后1年种植体周围软组织情况[红色美学标准(PES)评分]、种植体周围牙槽骨吸收值及种植体周围牙整齐度;手术并发症及术后1年修复体并发症发生情况。结果:GBR组患者治疗有效率高于常规组(P<0.05);骨愈合时间短于常规组(P<0.05);两组患者手术时间及离院时间比较,差异无统计学意义(P>0.05)。术后1个月及6个月,GBR组患者种植体ISQ高于常规组(P<0.05)。术后1年,GBR组患者种植体周围软组织PES评分、种植体周围牙槽骨吸收值、牙整齐度高于常规组(P<0.05)。两组患者手术并发症比较,差异无统计学意义(P>0.05);GBR组患者术后1年修复体并发症总发生率低于常规组(P<0.05)。结论:牙槽突扩张术联合GBR植骨术同期种植牙治疗有效率高,且牙齿发育异常患者预后效果更好。Objective:To explore the application effect of alveolar process expansion combined with guided bone regeneration(GBR)bone grafting simultaneous dental implantation on patients with abnormal tooth development.Methods:87 patients(94 teeth)with abnormal tooth development were included as the observation subjects.According to different treatment methods,they were divided into routine group(alveolar bone splitting,n=37,40 teeth)and GBR group(alveolar process expansion combined with GBR bone grafting,n=50,54 teeth).The effective rate of treatment,basic conditions of surgery(surgery time,hospital discharge time,and bone healing time)and the stability of implants[Stability coefficient(ISQ)]1 and 6 months after operation,soft tissue around the implant,alveolar bone absorption value around the implant and uniformity of the teeth around the implant at 1 years after surgery were compared between the two groups.The incidence rates of postoperative complications and implant complications in the two groups were statistically analyzed.Results:The effective rate of treatment in GBR group was higher than that in routine group(P<0.05),and the bone healing time was shorter than that in routine group(P<0.05).There was no statistically significant difference in the surgical time and discharge time between the two groups(P>0.05).The implant ISQ,soft tissue PES score around the implant,alveolar bone absorption value around the implant and tooth uniformity in GBR group were higher than those in routine group(P<0.05).There was no statistically significant difference in surgical complications between the two groups(P>0.05).The incidence rates of postoperative implant complications in GBR group were lower compared with those in routine group(P<0.05).Conclusion:The effective rate of alveolar process expansion combined with GBR bone grafting simultaneous dental implantation is higher,and the prognosis of patients with abnormal tooth development is better.
