摘　　要：目的分析牙周辅助成骨加速正畸(PAOO)治疗下颌骨前牙槽区骨开裂和开窗患者中的临床效果。方法回顾性总结2020年3月至2022年3月我院诊断下颌骨前牙槽区骨开裂或开窗患者共45例(239个位点),男性20例,女性25例,年龄21~45岁,平均(31.2±9.9)岁。均采用PAOO进行治疗,至少随访12个月。记录术前、随访6个月和12个月的临床参数和锥形束CT(CBCT)参数的变化趋势,其中临床参数包括出血指数(BI)、探诊深度(PD)、角化牙龈宽度(KGW)和牙龈退缩水平(GRL),CBCT参数包括牙根长度(RL)、牙槽嵴顶骨皮质厚度(CBT)、根中腭侧牙槽骨厚度(MBT)、上颌切牙区唇腭侧牙槽骨厚度(ABT)以及垂直槽骨高度(VBH)。结果GRL随着时间延长逐渐下降(F=4.898,P<0.05),而BI、PD和KGW无明显变化趋势(P>0.05)。CBT、MBT和VBH随着时间延长逐渐增加(F=5.032、9.032和7.253,P<0.05),而RL和ABT无明显变化趋势(P>0.05)。结论PAOO技术在软组织和硬组织增强方面对牙周状况有益,对治疗下颌骨前牙槽区骨开裂和开窗具有明显的治疗作用。Objective To analyze the clinical effect of periodontally accelerated osteogenic orthodontics(PAOO for patients with bone fenestration and dehiscence in mandibular anterior alveolar zone.Methods A retrospective review was conducted on 45 patients(239 sites)diagnosed with bone fenestration or dehiscence in mandibular anterior alveolar zone into our hospital from March 2020 to March 2022.There were 20 males and 25 females,aged 21~45 years,with an average age of(31.2±9.9)years.All patients were treated with PAOO and followed up for at least 12 months.Record the changes of clinical parameters and cone beam CT(CBCT)parameters before surgery,6 and 12 months after follow-up,clinical parameters included bleeding index(BI),probing depth(PD),keratinized gingival width(KGW),and gingival recession level(GRL),CBCT parameters included root length(RL),bone thickness at the crestal level(CBT),bone thickness at mid-root level(MBT)bone thickness at the apical level(ABT)and vertical bone height(VBH)of the root tip.Results 0.05),while BI,PD,and KGW showed no significant trend of change(P>0.05).CBT,MBT,and VBH gradually increased with time(F=5.032,9.032 and 7.253,P<0.05),while RL and ABT showed no significant change trend(P>0.05).Conclusion PAOO technique is beneficial to the enhancement of soft tissue and hard tissue in periodontal condition,and has obvious therapeutic effect on the treatment of mandibular anterior alveolar bone cracking and fenestration.
