【摘要】：目的:以面部及下頜骨正中矢狀面為參考平面,從頜骨位置和下頜骨輪廓2個方面對面部偏斜進(jìn)行分析和分類,為臨床診療提供依據(jù)。方法:利用ProplanCMF根據(jù)86例面部偏斜患者的術(shù)前CBCT資料構(gòu)建骨組織的三維模型及三維測量體系,從頜骨位置和下頜骨輪廓2個方面分析偏斜特點并建立一種分類體系。結(jié)果:頜骨偏斜分為3類:位置偏斜、下頜骨形狀偏斜、位置和下頜骨形狀均偏斜。位置偏斜有T類(水平向偏斜)和V類(垂直向偏斜)。T1和T3類中,偏側(cè)的下頜骨體長度、下頜升支高度、正面升支傾斜度、側(cè)面升支傾斜度和對側(cè)相比有統(tǒng)計學(xué)差異(P0.01);下頜平移偏斜病例數(shù)太少,不納入統(tǒng)計分析;V類中,偏側(cè)的正面升支傾斜度、下頜升支高度與對側(cè)相比有統(tǒng)計學(xué)意義(P0.01),而下頜骨體長度、側(cè)面升支傾斜度無統(tǒng)計學(xué)意義(P0.05)。偏側(cè)與對側(cè)的輪廓測量項目相比有統(tǒng)計學(xué)意義(P0.05)。結(jié)論:頜骨偏斜分類系統(tǒng)能夠詳細(xì)的反映頜骨位置和下頜骨形狀的偏斜特點,對疾病的診療提供一定的臨床依據(jù)。
[Abstract]:Objective: to analyze and classify the facial oblique from the position of the mandible and the outline of the mandible, taking the median sagittal plane of the face and mandible as the reference plane, so as to provide the basis for clinical diagnosis and treatment. Methods: according to the preoperative CBCT data of 86 patients with facial deviation, ProplanCMF was used to construct a three-dimensional model of bone tissue and a three-dimensional measurement system. The characteristics of deviation were analyzed and a classification system was established from two aspects: jaw position and mandibular outline. Results: there were three types of mandibular oblique: position oblique, mandibular shape oblique, position and mandibular shape oblique. There are T (horizontal skew) and V (vertical oblique) in position oblique. In T1 and T3, the length of mandible body, height of ramus of mandible, inclination of ascending branch in front of T 1 and T 3, The slope of lateral ascending branch was significantly different from that of contralateral side (P0.01). The number of cases of mandibular translation deflection was too small to be included in statistical analysis. In category V, there were significant differences in the inclination of the ascending branches and the height of the ramus between the two sides (P0.01), but there was no significant difference in the length of the mandibular body and the slope of the ascending branches of the lateral side (P0.05). Compared with the contralateral side, the profile measurement items were statistically significant (P0.05). Conclusion: the classification system of mandibular deviation can reflect the position of jaw and the shape of mandible in detail, and provide some clinical basis for the diagnosis and treatment of the disease.
