Modelling of dental geometry configuration / Mohd Shafiq Azni

In dentistry, determining the position and orientation for each tooth is mostly based on orthodontic qualitative perception. There is no standard method to obtain those values especially in three dimensional (3D) image which gives difficulty in some complicated cases. This study characterized and mo...
