摘要
目的研究正颌手术联合骨皮质切开术对骨性Ⅲ类错[牙合]畸形中硬组织及软组织相关指标的影响研究。方法选取2021年1月至2022年12月濮阳市第三人民医院收治的104例骨性Ⅲ类错[牙合]畸形患者,按手术方法不同分组,将接受常规正颌手术治疗的50例作为对照组,在对照组基础上接受骨皮质切开术辅助治疗的54例作为研究组,比较两组矫正时间、矢状方向移动距离、硬组织、软组织相关指标及并发症。结果研究组排齐上牙列、关闭间隙及总时间为(5.01±0.68)个月、(5.82±0.84)个月及(11.52±1.01)个月,均短于对照组,差异有统计学意义(P<0.05);研究组矢状方向移动距离上颌中切牙和上颌第一磨牙分别是(2.17±0.34)mm和(2.01±0.25)mm,与对照组的(2.12±0.54)mm和(2.06±0.42)mm比较,差异无统计学意义(P>0.05);治疗前两组软、硬组织相关指标比较,差异无统计学意义(P>0.05),治疗半年后硬组织相关指标均改善,研究组治疗后上齿槽座角(sella nasion A,SNA)及硬组织牙槽座点连线与腭平面的交角(upper alveolar edge Alveolar seat point,UARA)为(0.42±0.05)°、(12.42±1.64)°,均高于对照组,上牙槽座点到水平面垂直距离(upper alveolar seat point-horizontal plane,Sd-HP)及上牙槽缘点到冠状面垂直距离(upper alveolar seat point-coronal plane,Sd-CP)为(0.40±0.09)mm及(3.18±0.67)mm,均长于对照组,差异有统计学意义(P<0.05);两组治疗半年后软组织相关指标均改善,研究组治疗后鼻小柱前端至鼻底,与鼻底至上唇红唇间交角(nasal column;upper lip;crossing angle,NLA)(10.82±0.97)°,大于对照组,唇上点至HP的垂直距离(lip spot-horizontal plane,Ls-HP)与唇上点至CP的垂直距离(lip spot-coronal plane,Ls-CP)为(2.51±0.24)mm、(3.34±0.79)mm,均长于对照组,差异有统计学意义(P<0.05);治疗期间对照组并发症发生率6.00%,研究组并发症发生率7.41%,差异无统计学意义(P>0.05)。结论骨皮质切开术辅助正畸可缩短骨性Ⅲ类错[牙合]畸形矫正时间,提高治疗效果,且安全性高,值得推广。
Objective To study the application of corticotomy assisted orthodontics in the treatment of ClassⅢmaloc-clusion of bone.Methods A total of 104 patients with classⅢbone malocclusion treated in the Third Peoples Hospital of Puyang City from January 2021 to December 2022 were selected,and grouped according to different surgical methods.50 patients receiving conventional orthognathic surgery were selected as the control group,and 54 patients receiving cor-ticotomy as the study group on the basis of the control group.The correction time,sagittal movement distance,hard tis-sue and soft tissue related indexes and complications were compared between the two groups.Results In the study group,the total time of dental alignment,closing space and closure were(5.01±0.68)months,(5.82±0.84)months and(11.52±1.01)months,which were shorter than those in the control group(P<0.05).The sagittal dis-tance of maxillary central incisor and maxillary first molar in the study group was(2.17±0.34)mm and(2.01±0.25)mm,respectively,compared with(2.12±0.54)mm and(2.06±0.42)mm in the control group(P>0.05).The hard tissue related indexes of the two groups before treatment were compared(P>0.05),and the hard tissue related indexes of the study group were improved after six months of treatment,compared with those before treatment(P<0.05),and the SNA and UARA of the study group after treatment were(0.42±0.05)°and(12.42±1.64)°,both higher than those of the control group(P<0.05).Sd-HP and Sd-CP were(0.40±0.09)mm and(3.18±0.67)mm,both of which were longer than control group(P<0.05).Compared with the two groups before treatment(P>0.05),the soft tissue related indexes of the two groups were improved after six months of treatment,compared with that before treatment(P<0.05),and the NLA of the study group after treatment was(10.82±0.97)°,which was greater than that of the control group.Ls-HP and Ls-CP were(2.51±0.24)mm and(3.34±0.79)mm,both of which were longer than those in control group(P<0.05).During the treatment period,the complication rate of the control group was 6.00%and that of the study group was 7.41%,with no significant difference(P>0.05).Conclusion Corticotomy assisted orthodontics can shorten the correction time of classⅢmalocclusion of bone,improve the therapeutic effect,and have high safety,which is worth promoting.
