Abstract
Purpose: This study is to present a standard value for clinical crown angulation and inclination required inlaboratory process and see if the value can be used for actual laboratory process.
Methods: In order to find out a standard value for clinical crown angulation and inclination, this study made astudy model of normal occlusion of 21 females in twenties. The clinical crown angulation and inclination of bothsix-maxillary and six-mandibular anterior teeth are measured by Set-up Model Checker. From the measured valueabove, the mean and standard deviation of the twelve teeth are obtained, and then the mean of the teeth betweenright and left side is calculated.
Results: Each clinical crown angulation of maxillary central incisor, lateral incisor, and canine is like this; 1.01.3 , 3.0 1.3 , and 5.0 1.4 . In case of mandibular, each degree is like this; 0.6 1.1 , 1.5 1.1 , and4.1 1.1 . Each clinical crown inclination of maxillary central incisor, lateral incisor, and canine is like this; 6.11.8 , 4.5 1.9 , and -6.2 1.4 . In case of mandibular, each degree is like this; 0.3 1.5 , 0.3 1.8 , and-7.5 1.8 .
Conclusion: As the result, the mean value for clinical crown angulation and inclination can be referred to actuallaboratory process. However, the mean value is different from those of the precedent study and an unsatisfied onefor adopting the standard value.
