Facial aesthetic depends greatly on the presence of teeth specially maxillary anterior. Four-hundred-six patients (191 males and 215 females) were examined to investigate the variation of mesiodistal crown width and amount of tooth display between right and left maxillary anterior teeth. The result of this survey indicated that right and left maxillary anterior teeth are not always identical. A difference of up to 1 mm in mesiodistal width and the amount of tooth exposure between the right and left maxillary central incisors is considered to be within the range of normal appearance. Right and left maxillary lateral incisors and canines have the same range of difference as that of central incisors.
面部美学很大程度上取决于牙齿的存在，特别是上颌前牙。对406名患者（191名男性和215名女性）进行了检查，以研究上颌左右前牙之间近远中牙冠宽度和牙齿外露量的差异。这项调查结果表明，上颌左右前牙并不总是相同的。上颌左右中切牙之间近远中宽度和牙齿暴露量相差高达1毫米被认为在正常外观范围内。上颌左右侧切牙和尖牙的差异范围与中切牙相同。
