The position of lower incisor has been of considerable concern when planning an orthodontic treatment, having been recognized as one of diagnostic keys, Very important in the development of malocclusion and facial pattern.
In this study we claim to determine the importance of the position and inclination of lower incisor in the different malocclusions and facial patterns, and to base which of the cephalometric measurement parameters are the mostreliable. Material and methods. Ninety lateral radiographies were taken, and they were classified by skeletal malocclusion and facial pattern.These teleradiographies have been performed cephalometric analysis, which includelower incisor position belong the following analysis: Ricketts, Riolo, Tweed, McHorris, Jarabak-MSE and Holdaway.
Cross-sectional study where we perform statistical analysis Anova test, Pearson correlations and Bonferroni analysis. Results. The analyzed measurements present a statistically significant differentiation in lower incisor inclination respect to the anterior cranial base, McHorris angle, angulation of lower incisor respect to occlusal plane and mandibular plane.
There are statistically significant differentiation in lower incisor position and inclination respect the malocclusion and individual facial pattern.
在下颌切牙的位置时规划正畸治疗已相当关注，已被确认为诊断关键之一，在错畸形和面部模式的发展中非常重要。
在这项研究中，我们声称要确定在下颌切牙的位置和倾斜度在不同的错畸形和面部模式中的重要性，并确定哪些头影测量参数是最可靠的。材料和方法。共拍摄了 90 张侧位 X 光片，并根据骨骼错牙合和面部形态进行分类。这些 X 光片进行了头影测量分析，其中包括下颌切牙位置的以下分析：Ricketts、Riolo、Tweed、McHorris、Jarabak-MSE 和 Holdaway。
我们进行了统计分析方差分析、Pearson 相关和 Bonferroni 分析的横截面研究。结果。分析后的测量值在下颌切牙倾斜度相对于前颅底、McHorris 角、下颌切牙相对于咬合平面和下颌平面的角度方面存在统计学上的显著差异。
在下颌切牙的位置和倾斜度方面存在统计学上的显著差异，这与错牙合和个体面部模式有关。
