【Abstract】 Objective\ To provide a method and basic data for manufacture and measurement of gingival margin of complete denture of the youth based on computer technology.\ Methods\ 400 students, aged 17-25 years, were selected for this study. Models of upper and lower jaws were made, and the shape of gingival margin was measured with self designed multimedia computer diagnostic system and data.\ Results\ The measuring method of gingival margin and the data of the height of chord and length of the curve were obtained.\ Conclusion\ There is a law to be followed of the shape of X gingival margin . A comparison of the data of the shape with the width of upper middle incisor may reflect individual differences.更多还原
