上颌Nance弓联合TPA和微种植体支抗治疗双颌前突或上颌单颌前突的临床研究
Clinical Study on Maxillary Nance Arch Combined with TPA and Micro-implant Anchorage Control Anchorage in Treating Bimaxillary Protrusion or Monomaxillary Protrusion
摘要
Abstract
Objective To explore the clinical effect of maxillary Nance arch combined with transverse palatal arch(TPA)and micro-implant anchorage control anchorage in the treatment of bimaxillary protrusion or monomaxillary protrusion.Methods The clinical data of 54 patients with bimaxillary protrusion or monomaxillary protrusion in the hospital were retrospectively analyzed from From June 2021 to August 2024.According to different treatment methods,they were divided into Nance arch+TPA group(30 cases),combined group(24 cases).The Nance arch+TPA group was treated with maxillary Nance arch combined with TPA,while the combined group was added with micro-anchorage nail control anchorage on the basis of the Nance arch+TPA group.The orthodontic treatment time,cephalometric indexes(SNA angle,SNB angle,ANB angle,UI-NA angle,U1-SN angle,L1-NB angle,UL-EP,LL-EP),soft tissue change indexes(nasolabial angle,mental groove inclination angle)and periodontal indexes(gingival index,plaque index,probing depth,attachment loss)before and after treatment and occurrence of adverse reactions were compared among the groups.Results The complete closure time of extraction space and the orthodontic treatment time in combined group was shorter than that in Nance arch+TPA group(P＜0.05).After orthodontic treatment,the UI-NA angle,U1-SN angle,L1-NB angle,dental plaque index,gingival index,probing depth and attachment loss in combined group were lower than those in Nance arch+TPA group(P＜0.05),and the UL-EP,LL-EP distance,U1-L1 angle,the nasolabial angle and mental groove inclination angle were higher than those in Nance arch+TPA group(P＜0.05).The incidence of adverse reactions with 8.33%in combined group was lower than 33.33%in Nance arch+TPA group(P＜0.05).Conclusion Maxillary Nance arch combined with TPA and micro-implant anchorage control anchorage can shorten the orthodontic treatment time and improve the maxillary protrusion and soft tissue changes in the treatment of bimaxillary protrusion or monomaxillary protrusion,and it has high safety.关键词
