摘要
目的:比较不同矢状向错的颅底形态,探索其规律性。方法:选取均角型错牙合患者56例,年龄10～15岁,包括安氏Ⅰ类组17例;安氏Ⅱ类组20例,安氏Ⅲ类组19例。对三种牙合型进行颅底指标的测量分析,对测量指标进行单因素方差分析和两两比较。结果:从安氏Ⅱ类到安氏Ⅰ类再到安氏Ⅲ类错牙合患者后颅底长度依次缩短并有统计学差异;颅中基底角依次减小并有统计学差异;颅前基底角和后颅底平面角依次增大并有统计学差异。安氏Ⅱ类错的前颅底长度SN减小,安氏Ⅰ类和安氏Ⅲ类的SN长度没有显著的统计学差异。不同矢状向错牙合的颅底角,蝶鞍角,颅基底角,后颅底平面角和SO-Ar距均无统计学差异。结论:矢状向错牙合颅底结构呈现了一定的规律性,说明颅底的生长部分参与了错的形成;后颅底和蝶筛点对矢状向错的形成意义重大。
Objective：Compare the sagittal malocclusion of the cranial base morphology and explore their regularity.Method：Select patients seeking treatment for average angle of Class Ⅰ,Class Ⅱ and Class Ⅲ malocclusion,a total of 56 patients,age range 10 to 15 years old.Class Ⅰ group：17 cases;Class Ⅱ group：20 cases,Class Ⅲ group：19 cases.The three indicators of occlusal type of measurement and analysis of the base of the skull,occlusion of the three types of measure analysis of variance single factor analysis of pairwise comparisons.Result：Posterior of the base of the skull length from class Ⅰ via class Ⅱ to class Ⅲ,in turn reduce and then there are significant differences;Intermediat cranial base angle from the class Ⅱ via classⅠto class Ⅲ in turn reduce and then there are significant differences;Anterior cranial base angle and BaS-FH angle from class Ⅰ via class Ⅱ to class Ⅲ in turn increases and then there are significant differences.The SN length of class Ⅱ malocclusion decreases,there is no significant statistical difference between the SN length of classⅠ and class Ⅲ malocclusion.Combined with different sagittal cranial base to the cranial base angle,sella angle,cranial base angle,SN-FH angle and SO-Ar distance were not statistically different.Conclusion：The skull structures of sagittal malocclusion presents a certain regularity,it can be said cranial involved in the growth of the bottom part of the formation of malocclusion.Post-cranial base and the poit of SE involved in the formation of sagittal malocclusion.
