摘要

本研究的目的，在於建立國人正常咬合者牙冠舌側形態的資料，作爲臨床舌側矯正的參考。從大約5,000名高中與大專院校學生。印取45組最接近理想咬合者的牙科模型（男28人，女17人）作爲研究樣本。測量牙冠舌側近遠心傾斜與頰舌側斜角度，結果顯示，上顎除第二大臼齒以外，其他牙齒皆爲近心傾斜，最大近心傾斜爲犬齒。下顎除正門齒與側門齒以外，其他牙齒皆爲近心傾斜，最大近心傾斜爲第二大臼齒。最大遠心傾斜則爲側門齒。上顎皆爲唇（頰）側傾斜，最大唇（頰）側傾斜爲正中門齒。下顎除第一、二大臼齒以外，其他牙齒皆爲唇（頰）側傾斜；最大唇（頰）側傾斜爲正門齒，最大舌側斜則爲第一大臼齒。

Lingual orthodontics is used clinically. This study investigated the lingual crown angulation and inclination of optimal occlusion in Taiwanese people. The sample included 45 sets of dental study casts from 28 males and 17 females with optimal occlusion selected from approximately 5,000 young adults. Mesial tipping occurred in all teeth except the upper second molars, the lower central incisors, and the lower lateral incisors. The greatest mesial tipping was observed in the lower second molars. The greatest distal tipping was observed in the lower lateral incisors. Labial (buccal) inclination was observed in all teeth except the lower first molars and the lower second molars. Maximum labial inclination occurred in the upper central incisors. Maximum lingual inclination was observed in the lower first molars.
