【摘要】：目的：通过对撒拉族正常合青少年牙颌模型的测量,建立撒拉族正常合青少年牙、牙弓、基骨的正常值数据库；对比分析撒拉族青少年正常合牙、牙弓、基骨的特征；拟合完成中国撒拉族青少年正常合牙弓弓形图,为正畸临床的诊断、治疗和科研工作提供参考依据。方法：按照个别正常合的标准,对青海省循化县寄宿制高中在校生963人进行普查,严格挑选出个别正常合67名,其中男性43名,平均年龄16.7岁,女性24名,平均年龄17.2岁。制取全口牙颌模型,进行牙冠宽度、高度,牙弓宽度、长度,基骨宽度、长度,腭盖高度等指标的测量,测量值用SPSS17.0统计软件进行统计学分析,并与国内外相关研究结果进行比较,分析撒拉族青少年正常合牙颌特征；利用origin7.5软件,通过函数方程拟合完成中国撒拉族青少年正常合牙弓弓形图。结果： 1.撒拉族正常合青少年临床牙冠宽度,除上颌第二前磨牙女性大于男性外,其余均为男性大于女性,且尖牙牙冠宽度男性大于女性,差异具有统计学意义(P0.05)；牙冠宽度由大到小的排列顺序除男性下颌与保安族、藏族、蒙古族不同外,其余与其他所对比的民族一致。 2.撒拉族正常合青少年临床牙冠高度均为男性大于女性,且下颌第一前磨牙、第二前磨牙、第一磨牙、第二磨牙男性大于女性,差异具有统计学意义(P0.05)；牙冠高度大小的排列顺序除男性下颌与壮族不同外,其余与其他所对比的民族一致。 3.撒拉族正常合青少年牙弓宽度、长度,基骨宽度、长度,腭盖高度的测量结果均为男性大于女性,且UW6、UW6、LW6、PMBAWU、BALU、LL4、PH值男性大于女性差异具有统计学意义(P0.05)。 4.撒拉族正常合青少年PH-I指数、Bolton指数、Pont指数、牙弓指数男女间差异无统计学意义(P0.05),Howes指数中的PMBAWU/TMu6-6值,男女间差异有统计学意义(P0.05)。 5.拟合完成符合中国撒拉族正常合弓形特征的弓形图。讨论： 1.本研究结果进一步证明,不同地区、不同民族正常合牙、牙弓、基骨的大小、形态之间存在着差异,建立各地区、不同民族牙、牙弓、基骨的各项正常值数据库具有重要的意义。 2.撒拉族青少年各项指数(除Howes指数外)无性别差异；临床牙冠宽度、高度的排列顺序与其他所对比的民族基本一致。表明男女间、不同民族间各自的牙量与其牙弓大小是相对协调的。 3.本研究建立的撒拉族正常合青少年牙、牙弓、基骨的正常值数据库及拟合完成的中国撒拉族正常合青少年牙弓弓形图,可为正畸临床提供参考依据。
[Abstract]:Objective: By measuring the normal dental and maxillary models of Salar adolescents, a database of normal teeth, dental arch and base bone was established, and the characteristics of normal teeth, dental arch and base bone were compared and analyzed. The arcuate arches of Chinese Salar adolescents were fitted to provide reference for clinical diagnosis, treatment and scientific research of orthodontics. Methods: According to the standard of individual normal cooperation, 963 students of boarding high school in Xunhua County, Qinghai Province, were surveyed, and 67 students were strictly selected, including 43 males with an average age of 16.7 years and 24 females with an average age of 17.2 years. The crown width, height, arch width, length, base bone width, length and palatal height were measured by SPSS17.0 software. Compared with the related research results at home and abroad, this paper analyzed the normal dental and maxillary characteristics of Salar adolescents and completed the arcuate map of Chinese Salar adolescents by using origin7.5 software and functional equation fitting. Results: 1. The clinical crown width of normal Salar adolescents was larger than that of female maxillary second premolars, and the width of canine crown was larger than that of female, and the width of maxillary second premolar was larger than that of male, and the width of maxillary second premolar was larger than that of female. The difference was statistically significant (P 0.05), the crown width was arranged from large to small, except for male mandible and Gangan, Tibetan and Mongolian, the rest were the same as other contrasting nations. 2. The clinical crown height of normal Salar adolescents was higher than that of female, and the mandibular first premolars, second premolars, first molars, second molars and second molars were higher in male than female. The difference was statistically significant (P 0.05), and the arrangement order of crown height was the same as that of other contrasting nations except male mandible and Zhuang nationality. 3. The width of arch, length, width of base bone, length of base bone, height of palatal lid of normal Salar adolescents were larger than that of female, and the PH value of UW6 UW6 and PMBAWU BALULL4 in males was higher than that in females (P 0.05). 4. There was no significant difference between male and female in PH-I index and dental arch index. There was no significant difference in PMBAWU/TMu6-6 value between male and female, but there was significant difference between male and female (P 0.05). 5. Fitting the arcuate map of the normal arcuate of the Salar nationality in China. Discussion: 1. The results further demonstrated that there were differences in the size and shape of the normal teeth, dental arch, and basal bone in different regions and nationalities, and the establishment of different regions, different ethnic groups, dental arch, dental arch and dental arch. The database of normal value of base bone is of great significance. 2. There was no gender difference in all indexes (except Howes index) and the arrangement order of clinical crown width and height was basically the same as that of other contrasting nationalities. The results showed that the tooth size and dental arch size of men and women were relatively harmonious. 3. The database of normal teeth, dental arch and base bone of Salar nationality adolescents and the arcuate map of Chinese Salar normal adolescents can provide reference for orthodontic clinic.
