安徽地区正常（牙合）人群颅颌面部的三维头影测量

安徽地区正常（牙合）人群颅颌面部的三维头影测量摘要：目的：本文旨在对安徽地区正常（牙合）人群的颅颌面部进行三维头影测量，以期提供该地区口腔领域的基础数据和参考。

方法：选取100名安徽地区正常（牙合）人群中的50名男性和50名女性，通过三维头影测量系统对其颅颌面部进行测量，获得各项数据，并对结果进行统计分析。

结果：经过测量和统计分析，发现安徽地区正常（牙合）人群头颅各项数据与全球平均值相近，但颞骨凸度指数略高于平均值。同时，男性与女性在一些测量指标上存在明显差异，如垂直面夹角和上牙弓高度等。

结论：安徽地区正常（牙合）人群的颅颌面部三维头影测量结果为常数，但同全球平均值相比，颞骨凸度指数略高，可为该地区口腔领域提供参考数据。

Abstract:Objective:Thispaperaimstoconductthree-dimensionalcephalometricmeasurementsonthecraniofacialregionofnormal(occlusion)populationsinAnhuiregion,inordertoprovidebasicdataandreferencefortheoralfieldofthisregion.

Method:Fiftymalesandfiftyfemaleswereselectedfromthenormal(occlusion)populationinAnhuiregion,andtheircraniofacialregionsweremeasuredwithathree-dimensionalcephalometricmeasurementsystem.Variousdatawereobtained,andtheresultswerestatisticallyanalyzed.

Result:Aftermeasurementandstatisticalanalysis,itwasfoundthatthecraniofacialmeasurementsofthenormal(occlusion)populationinAnhuiregionweresimilartotheglobalaverage,butthetemporalboneconvexityindexwasslightlyhigherthantheaverage.Meanwhile,thereweresignificantdifferencesbetweenmalesandfemalesinsomemeasurementindicators,suchastheverticalplaneangleandtheupperdentalarchheight.

Conclusion:Thethree-dimensionalcephalometricmeasurementresultsofthecraniofacialregionofthenormal(occlusion)populationinAnhuiregionareconstants,butthetemporalboneconvexityindexisslightlyhigherthantheglobalaverage,whichcanprovidereferencedatafortheoralfieldofthisregion.
