【摘要】:目的:測量無牙頜患者總義齒修復(fù)前后軟組織三維面像的改變,為總義齒修復(fù)結(jié)果預(yù)測提供數(shù)據(jù)支持。方法:選取20例AtwoodⅡ類牙槽嵴吸收的無牙頜患者,使用DSC-2型面部三維成像系統(tǒng)進行總義齒修復(fù)術(shù)前、術(shù)后面部輪廓數(shù)據(jù)獲取和重建,并將每一患者術(shù)前、術(shù)后三維面像進行重疊,建立坐標系,評價術(shù)前、術(shù)后軟組織三維輪廓的改變。結(jié)果:AtwoodⅡ類牙槽嵴吸收的患者總義齒修復(fù)后面像改變主要集中在上唇及口角部位,下唇及頦部位移不明顯,前后方向上的位移垂直方向上的位移左右方向上的位移?偭x齒修復(fù)術(shù)后面部關(guān)鍵距離變化,除左-右口角間距稍有減小外,左-右上唇緣點間距、左-右下唇緣點間距、上-下唇凹點間距、上-下唇凸點間距均增加。結(jié)論:通過三維面部照相及測量分析,可以定量評價總義齒修復(fù)前后的顱頜面軟組織三維特征變化,有助于總義齒修復(fù)結(jié)果預(yù)測,提高患者的滿意程度。
