摘要
目的分析探究正畸临界患者给予拔牙或非拔牙疗法其硬组织变化的长期观疗效。方法该研究选取2011年1月—2012年1月该院就诊患者中被确诊为正畸临界的患者共44例,按照随机数字表法分为不拔牙组22例和拔牙组22例。拔牙组采用拔牙正畸治疗,非拔牙组采用非拔牙正畸治疗。在治疗结束时、治疗后随访时,分别对两组的中线、侧方咬合对位关系、牙齿排列、覆颌覆盖以及容貌美观度等硬组织相关指标进行评分,评分以10分制进行,10名医生参与评价过程,计算结果取平均值。结果治疗结束时,拔牙组容貌美观程度得分(9.10±0.23)分高于非拔牙组(8.88±0.15)分,随访时,拔牙组容貌美观程度得分(9.13±0.38)分高于非拔牙组(8.67±0.51)分,差异有统计学意义(P<0.05);治疗结束及随访时,两组牙齿排列、中线、侧方咬合对位关系和覆颌覆盖等评分比较,差异无统计学意义(P>0.05)。结论正畸临界患者给予拔牙或非拔牙正畸疗法其硬组织变化的长期观疗效均可取得较好治疗效果。但拔牙疗法相比于非拔牙正畸疗法在容貌及美观方面,效果更加显著。
Objective To analyze and study the long-term curative effect of extraction and non-extraction treatment of hard tissue changes of orthodontic critical cases.Methods 44 cases of orthodontic critical patients diagnosed in our hospital from January 2011 to January 2012 were selected and randomly divided into two groups with 22 cases in each,the extraction group adopted the orthodontic treatment,while the non-extraction group adopted the non-extraction orthodontic treatment,the hard issues related indexes such as midline and lateral occlusion alignment,arrangement of teeth,coverage of the jaws and beauty of the appearance were scored at the end of treatment and after treatment with ten-score system,and 10 doctors participated in the evaluation course,calculated the results and took the average value.Results At the end of treatment,the appearance beauty score in the extraction group was higher than that in the non-extraction group[(9.10±0.23)points vs(8.88±0.15)points],at follow-up,the appearance beauty score in the extraction group was higher than that in the non-extraction group,[(9.13±0.38)points vs(8.67±0.51)points],and the differences between groups were statistically significant(P<0.05),and the differences in the teeth arrangement,midline,lateral occlusion alignment and coverage of the jaws between the two groups were not statistically significant(P>0.05).Conclusion The long-term curative effect of extraction and non-extraction treatment of hard tissue changes of orthodontic critical cases is good,but the appearance and beauty effects of extraction therapy is more obvious than those of non-extraction orthodontic therapy.
