영문 초록

Over the 200 years ago, Hunter(1771) recognized that mandibular bone actually grows in a predominantly upward and backward direction toward the base of the skull. Charles(1925) has described the importance of the condyle in the mandibular growth. Most authors agree that the mandibular growth occur predominantly at the condyle(Brodie, 1941, Björk, 1955, Sarnart & Robinson, 1956). But recent theoretical and experimental studies have fundamentally altered our understanding the growth process of the mandible. In opposition to the condyle as a primary site of mandibular growth, Moss (1960, 1968) postulated the functional matrix hypothesis that the mandible is composed of various funtional components, including an alveolar portion, the coronoid process, the gonial region, the condyle area, and corpus portion. Growth of the mandible is the sum of growth of all of its functioal component which has independent growth. He proposed that the relation of funtional components has an invariable ratio. A similar conclusion reached by Precious & Delaire(1987). The aim of this study is to observe the ratio and correlation between the functional components of the mandible in Korean normal adults on the basis of the Moss and Delaire s hypothesis. The author selected 57 females and 60 males who have normal faces in Korean adults. Using the Panoramic X-ray, the author measured the length the condyle, coronoid process, angle portion, corpus portion from lingular and ramal height. The result as follows ; 1. There were significant invariable ratio and correlation between the ratio of length of condyle, coronoid and corpus portion. 2. In both sexes, the absolute length of ramus, condyle, coronoid, angular and corpus were significantly difference. 3. There were correlation in the length of each counterpart between right and left side. 4. The ratio between the length of condyle and coronoid was 1.2302±0.110 in the female group and 1.2277±0.120 in the male group. The ratio between the length of condyle and corpus was 0.5233±0.047 in the female group and 0.5266±0.043 in the male group. The ratio betwen the length of coronoid and corpus was 0.4282±0.044 in the female group and 0.4313±0.039 in the male group.
