2、朝向没有显著性差异。鼻部数学变量测量方面:安氏I类、安氏II类1分类患者相比,两类错牙合畸形患者的鼻部各组成的长度基本相同,但是鼻背、鼻尖、鼻柱的轮廓曲线存在显著差异:男性、女性患者相比,女性患者的鼻部各部分长度测量结果数值都比男性小,且女性患者的鼻背形状比较曲折,鼻尖比较圆缓,鼻尖总的突度比较小。(2)第二部分研究结果A组和B组矫治前后线距测量指标变化明显(P3、(1)安氏I类、安氏II类1分类患者的鼻部形态各组成长度方面差异不明显,但安氏II类患者的鼻尖形状比较圆缓,鼻尖朝向比较靠上,致使连接鼻尖点与颏前点组成的审美线位置比较靠后。(2)男性、女性患者相比,女性患者的鼻部各组成部分长度测量指标均小,女性患者鼻背形状曲线比较曲折,鼻尖比较圆缓,鼻尖总的突度比较小。(3)正畸治疗能促进鼻部垂直方向上的发育,对鼻部形态影响不大。5.关键词安氏lI类1分类;鼻部;头影测量;生长发育2山东人学硕1二学位论文Thestudyofnasalsofttissueprofileforpa4、tientswithClassⅡDivision1malocclusionPostgraduateLiulingSpecialtyOrthodonticsTutorProf.WangchunlingAbstractobjective:Theaimsofthisstudyweretoinvestigatenasalshapedifferercesbetweenpatients、撕thClassImalocclusionandpatientswithClassIIDivisionlmalocclusio,differ5、encesbetweenmaleandfemalepatientsbycephalometricanalysis.Anymore,nasalshapechangesfollowedbyorthodontictreatmentorgrowthanddevelopmentwerealsoinvestigated.Allofthiswagtogiveproposalformakingorthodonticplans.Methods:Thereweretwocompositionsinourstudy.1.Thefirs6、tpartWastheanalysisofthenasalshapedifferercesbetweenpatientswitllClassImalocclusionandpatients晰mClassIIDivisionlmalocclusion,differencesbetweenmaleandfemalepatients.14patients、析t11ClassImalocclusionorwithClassIIDivisionlmalocclusioninfastigiumofgrowthanddevel7、opmentwereselected(agell~14years).nemaleandfemaleoneswereequalineachmalocclusion.Takinglateralcephalometricradiographsinrelaxedheadposition.Twentytwoparametersweregainedbytheviewpointoftenorthodonticdoctorsandtheproportionofeachpositionsonnasalwereawared.Maki8、ngthedefinitionofcoordinatesystemwiththetruehorizontalplanetomeasureparametersofnasaldorsum,nasaltipandnasalbridge.111edatewereanalyzedof、历thSPSS16.0softwarepackage,usingchi·squaretestfor
