Application of periodontally accelerated osteogenic orthodontics for patients with bone fenestration and dehiscence in mandibular anterior alveolar zone
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 GRL gradually decreased over time(F=4.898,P<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.
