摘要

目的:在正畸治疗中,牙槽骨的厚度限制了牙齿的活动。本研究评估不同牙颌倾斜度的上中切牙周围皮质骨厚度。材料和方法:本横断面研究分析了318个上颌断层扫描体积,评估了每个体积的上颌中切牙,测量了636个中切牙。使用Veraviewpocs Morita系统获得上颌层摄影图像,视野为100 × 40 mm。使用i-Dixel软件重建图像。两名校准的调查人员进行了所有测量,重点关注四个部分的骨厚度:颈颊、腭、尖颊和腭尖。同样地,上中切牙的倾斜度也被分类为唇部倾斜、适当倾斜或腭面倾斜。统计分析包括方差分析(单因素方差分析)和多元线性回归检验(p < 0.05)。结果:上中切牙周围的骨厚度的比较,特别是颈颊,腭,尖颊和尖腭显示相似的值在所有三组分类,根据腭倾斜。然而,多元线性回归分析显示,从唇侧或腭侧倾斜到适当倾斜位置的改变会影响颈颊骨厚度,导致颈颊骨厚度减少0.09 mm (p = 0.029)。结论:无论上中切牙的颊腭倾斜度如何,所评估的四个区域的皮质骨厚度都保持不变。虽然颈颊骨厚度的一些变化具有统计学意义,但这些变化与临床无关。临床意义:很少有研究表明上牙的倾斜度会影响骨的厚度。如果这个参数保持不变,正畸医生应该考虑改变他们的治疗计划。本文引用方式:Plaza-Serrano MA, Robayo-Alvarado SL, Llaguno-Rubio JM等。不同类型颊腭倾斜上中切牙皮质骨厚度的CBCT评价。[J]现代医学学报,2015;26(3):239-243。

Evaluation of Cortical Bone Thickness in Upper Central Incisors with Different Types of Buccopalatal Inclination: A CBCT Study.

Aim: The thickness of the alveolar bone restricts dental movements in orthodontics. This study evaluated cortical bone thickness surrounding the upper central incisors with different buccopalatal inclinations.

Materials and methods: This cross-sectional study analyzed 318 maxillary tomographic volumes, assessing both maxillary central incisors of each volume, resulting in the measurement of 636 central incisors. The maxillary tomographic images were obtained using a Veraviewpocs Morita system with a field of view of 100 × 40 mm. The images were reconstructed using i-Dixel software. Two calibrated investigators performed all the measurements, focusing on bone thickness in four sectors: Cervical buccal, palatal, apical buccal, and apical palatal. Likewise, the inclination of the upper central incisors was categorized as labially inclined, adequately inclined, or palatally inclined in relation to the palatal plane. Statistical analysis included analysis of variance (one-way ANOVA) and multiple linear regression tests (p < 0.05).

Results: A comparison of bone thicknesses around the upper central incisor, specifically cervical buccal, palatal, apical buccal, and apical palatal revealed similar values across all three groups categorized according to buccopalatal inclination. However, multiple linear regression analysis indicated that the change from either labially or palatally inclined to an adequately inclined position affects cervical buccal bone thickness, resulting in a decrease of 0.09 mm (p = 0.029).

Conclusion: The thickness of the cortical bone in the four areas evaluated remained unchanged regardless of the buccopalatal inclinations of the upper central incisors. Although some changes in cervical buccal bone thickness were statistically significant, these changes are not clinically relevant.

Clinical significance: Few studies have indicated that the inclination of the upper teeth can affect the thickness of the bone. If this parameter remains constant, orthodontists should consider these changes in their treatment plans. How to cite this article: Plaza-Serrano MA, Robayo-Alvarado SL, Llaguno-Rubio JM, et al.
