[Abstract]:Objective: to establish the normal value of all the indexes of normal occlusal Ricketts cephalometric analysis method in Changchun Han adolescents, and to make a comparative study on the difference between male and female, so as to fill in the deficiency of the existing Ricketts cephalometric analysis methods in Changchun area, and to provide a reference value for the clinical application of Ricketts cephalometric analysis in case diagnosis, correction design and curative effect prediction. Compared with other cephalometric analysis methods, Ricketts analysis method has its unique advantages, that is, growth prediction and prognosis judgment, which is helpful for orthodontists to provide patients with a more comprehensive and precise corrective scheme, improve the success rate of correction and reduce the recurrence rate. Experimental methods: a general survey of individual normal occlusal among Han adolescents was carried out in primary and secondary schools in Changchun, Jilin Province. The selection criteria were as follows: (1) Han adolescents from Changchun, Jilin Province; (2) healthy teeth, no obvious caries and defects; (3) individual normal occlusal (except the third molar, the number of teeth was normal; molar relationship: neutral relationship, overbite in anterior occlusal area, normal overbite, good occlusal relationship; (4) the appearance and side appearance of soft tissue were basically coordinated, the shape and function of lip muscle were normal; (5) there was no TMJ disease; (6) there was no bad oral habit such as unilateral mastication and no night molars; (7) there was no history of maxillofacial and neck trauma; (8) there was no history of orthodontic treatment or orthodontic surgery; (9) there was no systemic disease of the whole body. 65 cases of normal occlusal adolescents in the early stage of permanent teeth were selected: male (30 cases) and female (35 cases) (mean age: 14.07 鹵1.72, female: 14.34 鹵1.43). The lateral cephalometric films were taken in the natural head position, and the indexes of Ricketts analysis method were measured by dolphin17.0 software. After the measurement results were processed by SPSS17.0 software, the normal value range of each measurement index of Ricketts analysis method was established by means of mean 鹵standard deviation (X 鹵S), and the differences between male and female were compared by t test, P 0.05. Results: the normal values of all the indexes of normal occlusal Ricketts analysis were obtained in Changchun Han adolescents, and the statistical results of Ricketts analysis showed that there was no significant difference in other indexes except point A protruding degree, maxillary depth angle, maxillary body length and anterior skull base length (P 0.05). Conclusion: the normal values of Ricketts analysis method for normal occlusal of Han nationality adolescents in Changchun can be used for clinical diagnosis, correction design and prognosis analysis of orthodontic patients of Han nationality adolescents in Changchun area. The Ricketts analysis method of Han nationality adolescents in Changchun showed that there was no significant difference in dental factors, tooth-bone correlation factors and aesthetic factors, A point protrusions in bone factors, maxillary depth angle in facial relative skull factors, and no significant differences in tooth sex factors, tooth-bone correlation factors and aesthetic factors. In the internal structural factors of skull, the length of mandibular body, the length of anterior skull base and the measured value were all male and female, and the gender difference was statistically significant, so the gender difference should be considered in clinical orthodontic diagnosis, design and analysis.
