【摘要】：目的:通过Q分类法评价不同人群对唇珠位置偏斜患者的牙列中线位置的美学评价差异。方法:利用Adobe Photoshop CS6软件将男女模特照片处理为唇珠中点偏移和唇珠中点、牙齿同时偏移的模板,以1 mm为增量,左右各3 mm,得到符合要求的男性女性各13张照片。由160名口腔医生(78男,82女)、165名正畸患者(82男,83女)、163名大一新生(78男,85女)用Q分类法进行牙列中线位置的美学评价。获得的相关数据经SPSS23.0进行统计学单向方差分析、两两对比及t检验分析,P0.05时,结果具有统计学意义。结果:1、大部分口腔医生能识别出2 mm以下的偏斜,但当唇珠中点偏斜1 mm时,对牙列中线与唇珠中点或与面中线保持一致的选择无显著性统计学差异。当唇珠中点偏斜≥2 mm时,首选上颌牙列中线与面中线一致且有统计学意义。2、大部分正畸患者及大一新生不能辨别出2 mm以下的偏斜,且当唇珠中点偏斜≤2 mm时,对于上颌牙列中线位置的选择无统计学差异。当唇珠中点偏斜3 mm时,正畸患者与学生优先选择上颌牙列中线与面中线一致且具有统计学意义。3、与美学相关性密切的科室(正畸科、修复科、种植科)的医生相比其他科室医生审美评价更具有一致性,且要求严苛,对偏斜程度敏感性高。当唇珠中点偏斜时,其优先选择牙列中线与面中线一致且具有统计学意义。4、不同性别的评价者对多组女性模特照片的评价存在显著差异,而在偏斜程度为1 mm时,女性的辨识程度较男性高。5、多数左右偏斜相同程度的照片,向右侧偏斜比向左侧偏斜的照片平均Q得分低,被认为更具有吸引力。结论:1、非专业人士对唇珠中点≤2 mm的偏斜感知度低,正畸医生在矫正过程中对于牙列中线的位置选择应提供正确的审美导向,尤其是年轻女性患者应做好充分的术前沟通。2、当唇珠中点偏斜且偏斜量达到3 mm时,大众更能接受牙列中线与面中线一致的治疗方法,而非牙列中线与唇珠中点位置一致的治疗方案。3、牙齿矫正过程中,牙列中线、唇珠中点、面中线间的不调关系应尽量控制在2 mm以内。
[Abstract]:Objective: through the Q classification method to evaluate the teeth on the lip bead position deviation patients among different column aesthetic evaluation midline differences. Methods: using Adobe Photoshop CS6 software will be male and female models photo processing lip lip bead and bead midpoint offset midpoint, teeth at the same time offset of the template, with 1 mm increments of about 3 mm. Get in line with the requirements of the male and female each 13 photos. By 160 dentists (78 male, 82 female), 165 orthodontic patients (82 male, 83 female), 163 freshman (78 male, 85 female) with Q classification of dentition aesthetic evaluation of midline. Relevant data received it was analyzed by SPSS23.0 statistical analysis, one-way ANOVA, t test and comparison of 22 P0.05, the results were statistically significant. Results: 1, most dentists can identify 2 mm deflection, but when the midpoint deflection of lip beads at 1 mm of dental midline with lip beads or stay with the midline point The same choice no statistical significant difference. When the midpoint deflection lip bead was greater than 2 mm, the preferred maxillary dental midline with midline consistent and statistically significant.2, and most patients were freshman can identify 2 mm below the deflection, and when the midpoint deflection of lip beads less than 2 mm, the maxillary teeth column midline selection showed no significant difference. When the midpoint deflection lip bead 3 mm, and the students preferred orthodontic patients of maxillary dentition and midline midline consistent and statistically significant.3, close correlation and aesthetics (Department of Orthodontics, Department of Prosthodontics, Department of plant) doctor compared to other doctors with more aesthetic evaluation consistency and demanding, the deflection degree of high sensitivity. When the midpoint deflection of lip bead, the preferred dental midline with midline consistent and statistically significant.4, evaluation of different gender on groups of female models There are significant differences in the evaluation sheet, skewness is 1 mm, the identification degree of female is higher than male.5, most about the same degree of deviation of photos, skewed to the right than the average score is skewed to the left photo Q low, is considered more attractive. Conclusion: 1, non professionals of vermilion point less than 2 mm of the low degree of skewed perception, orthodontic doctors in the correction process for dental midline position should provide correct aesthetic direction, especially young women should make full preoperative communication.2, when the midpoint deflection and deflection of lip beads reached 3 mm, the public can accept dental treatment the midline midline and consistent, and non dentition treatment of midline and lip bead midpoint position consistent.3 orthodontic process, dental midline, the midpoint of the midline cleft lip, the relationship should be controlled within 2 mm.
