摘要/Abstract

摘要： ［摘要］目的比较拔牙矫治与非拔牙矫治对牙弓宽度及颊廊的影响，并探讨颊廊与牙弓宽度改变的关联性。方法收集符合要求的拔牙矫治与非拔牙矫治患者各50例，用石膏模型测量牙弓宽度，用正面自然微笑相测量颊廊宽度，比较拔牙矫治前后牙弓宽度及颊廊宽度的改变量、非拔牙矫治前后牙弓宽度及颊廊宽度的改变量，研究拔牙对牙弓宽度及颊廊宽度的影响，并通过分析牙弓宽度的改变量与颊廊宽度的改变量之间的关联性来探究拔牙与否对牙弓宽度及颊廊宽度的影响是否存在相关性。结果 ①拔牙组矫治后的上尖牙牙弓宽度增加，非拔牙组无明显增加；②拔牙组与非拔牙组矫治后前磨牙宽度均有所增加，但拔牙组增加量大于非拔牙组；③拔牙组与非拔牙组矫治后上颌第一磨牙间的宽度均有所增加，但非拔牙组增加量大于拔牙组；④拔牙组与非拔牙组矫治前后的颊廊宽度均无统计学差异；⑤拔牙组与非拔牙组矫治前最后可视磨牙的宽度、矫治后尖牙牙弓宽度与颊廊宽度有相关性。结论 ①矫治前后牙弓宽度的改变与拔牙与否有关；②矫治前后颊廊的改变与拔牙与否无关；③牙弓宽度的改变与颊廊的改变在大多数情况下无直接的相关性。

Abstract: Abstract: Objective To compare the pretreatment and posttreatment changes of arch widths and buccal corridor widths between premolar extraction and nonextraction treatment,and to analyze the correlation between arch width changes and buccal corridor width changes.Methods Pretreatment and posttreatment casts,frontal smiling photographs of 50 extraction and 50 nonextraction patients were collected to obtain their corresponding pretreatment and posttreatment changes of arch widths and buccal corridor widths.The amount of changes between pretreatment and posttreatment archwidths and buccal corridor widths were measured in order to explore the extraction effects on them，and the correlations between the changing amounts of arch widths and that of buccal corridor widths were measured as to compare the extraction effects on arch widths and buccal corridor widths.Results ①There was a significant increase inthe posttreatment maxillary intercanine width in the extraction group but not in the nonextraction group.②Pretreatment and posttreatment arch widths between the maxillary premolars in both groups increased,and the amounts were greater in the extraction group than in the nonextraction group.③Pretreatment and posttreatment arch widths between the maxillary first molars in both groups increased,and the amount was greater in the nonextraction group than in the extraction group.④There were no significant differencesin any buccal corridor widths measured in both groups.⑤There were correlations between the pretreatment first molar and posttreatment canine arch widths and the buccal corridor widths.Conclusions The pretreatment and posttreatment changes of arch widths are related to extraction，while the buccal corridor widths are not.Besides,these arch width differences are not directly related to changes of buccal corridor widths in most cases.
