安徽地區(qū)正常（牙合）人群顱頜面部的三維頭影測(cè)量

安徽地區(qū)正常（牙合）人群顱頜面部的三維頭影測(cè)量摘要：目的：本文旨在對(duì)安徽地區(qū)正常（牙合）人群的顱頜面部進(jìn)行三維頭影測(cè)量，以期提供該地區(qū)口腔領(lǐng)域的基礎(chǔ)數(shù)據(jù)和參考。

方法：選取100名安徽地區(qū)正常（牙合）人群中的50名男性和50名女性，通過(guò)三維頭影測(cè)量系統(tǒng)對(duì)其顱頜面部進(jìn)行測(cè)量，獲得各項(xiàng)數(shù)據(jù)，并對(duì)結(jié)果進(jìn)行統(tǒng)計(jì)分析。

結(jié)果：經(jīng)過(guò)測(cè)量和統(tǒng)計(jì)分析，發(fā)現(xiàn)安徽地區(qū)正常（牙合）人群頭顱各項(xiàng)數(shù)據(jù)與全球平均值相近，但顳骨凸度指數(shù)略高于平均值。同時(shí)，男性與女性在一些測(cè)量指標(biāo)上存在明顯差異，如垂直面夾角和上牙弓高度等。

結(jié)論：安徽地區(qū)正常（牙合）人群的顱頜面部三維頭影測(cè)量結(jié)果為常數(shù)，但同全球平均值相比，顳骨凸度指數(shù)略高，可為該地區(qū)口腔領(lǐng)域提供參考數(shù)據(jù)。

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.
