【摘要】 本文提出一种利用特殊的镜面成像系统进行三维图像分析和测量方法。作者应用这种方法对62付正常颌模型的三维特征进行测量,对每付正常颔模型均测出96个数据并进行统计分析,本文选用牙弓和齿槽座的宽度、长度和周长;以及腭盖高度的数据进行分析研究,得出北京18～25岁青年正常(牙合)均值、标准差、t 值和 P 值。实践证明,这种方法比用游标卡尺或其他三维测量方法有准确性高、简单易行和测量速度快等显著优点。更多还原

【Abstract】 Using a special mirror group,a three demensional image analysis and meas-urement method is provided.By this method,the authors have finished the me-asarements of all the three demensional characteristics of 62 dental casts.For each dental cast,96 data were collected and have been statistical analy-sed.In this paper,we selected the data of the width,length,circle length and palatal height of dental arches and the dental basal bones.Studying and an an-alysing these data,we got the eighteen-year to twenty-five-year young men and women with normal occlusion,standard diviation,t value and P value.Practice have proved that there are a lot of advantages to this method.Compare with the method using vernier calliper and another three demensional measurement methods,it is more accurate and it is able to operate easily and quickly.更多还原
