某些作者曾建议用面部测量法作为选择人工牙的依据。如Berry 的生物统计比例法是基于上颌切牙和面宽的比例为1∶16。在选择前牙时,以上中切牙的挑选为最重要。牙齿的宽度较牙齿的长度更重要。左右切牙宽度的差别则并不重要。成人两眼的相对宽度在一生的早期就已定型。Laestadium 等指出78%成人内眦间距在1岁时定型。Lucas 等认为成人瞳孔间距在14岁时定型,并发现成年男性及女性的平均值为5.8cm。本研究对100名志愿人员作了上颌中切牙和瞳孔间距的测量。瞳孔间距是指一侧瞳孔中心至另一侧瞳孔中心的距离。切牙近远中宽度是量其最宽处。测量结果表明在不同性别和人种之间存
Some authors have suggested that facial measurements be used as the basis for selecting artificial teeth. For example, the biometric ratio of Berry is based on a ratio of maxillary incisors to face width of 1:16. In the choice of anterior teeth, the selection of the above incisors is the most important. The width of the tooth is more important than the length of the tooth. The difference between the left and right incisors is not important. The relative width of both adults has been stereotyped early in life. Laestadium and others point out that 78% of adults had internal fixation at 1 year of age. Lucas et al. Determined that adult pupil spacing was set at 14 years of age and found that the average adult male and female was 5.8 cm. In this study, 100 volunteers were measured for maxillary central incisor and interpupillary distance. Pupil distance refers to the distance from one side of the pupil center to the center of the pupil on the other side. Closing the width of the incisors is the amount of its widest point. The measurement shows that there is a difference between genders and races
