Original articleMaxillary width and hard palate thickness in men and women with different vertical and sagittal skeletal patterns
Section snippets
Material and methods
The research was done at the Stomatological Hospital of Shandong University, from which information on consecutive records of 93 men and 148 women were obtained. Patients aged 18 to 25 years with permanent dentition were selected as experimental objects, excluding the effects of growth and development. All subjects were Chinese Northerners with the following exclusions: (1) craniofacial anomalies, syndromes, severe asymmetries, and clefts; (2) crossbites and history of orthodontic treatment;
Results
The retrospective power was from 0.795 to 0.942. The intraobserver reliability of the measurements of all descriptions using SPSS software was excellent, with intraclass correlation ranging from 0.812 to 0.933. The Kolmogorov-Smirnov analysis and Fanchazzi test showed that each data set conformed to the homogeneity of variance tests and normal distribution. Two-way analysis of variance showed significant differences between groups (Tables II, III, V, and VI). Therefore, craniomaxillofacial bone
Discussion
This study focused on the differences in transverse width and hard palate thickness in sagittal and vertical patterns. Although our experiment was designed on the basis of sex, we found that the transverse differences recorded in vertical and sagittal groups for both men and women were the same. When we further analyzed craniomaxillofacial morphology between the sexes, 3D differences were also found, which provides references in treatment timing and prognosis of different skeletal patterns
Conclusions
For both men and women, maxillary width, to some extent, is correlated with vertical and sagittal skeletal patterns. Insufficient maxillary width would lead to unfavorable anteroposterior and vertical skeletal types.
There are differences in the morphology of craniomaxillofacial bone between the sexes. Women tend toward a Class II and hyperdivergent pattern. The conclusion proves to clinicians that vertical control and risk assessment of temporomandibular disorder are crucial in the treatment of
