Abstract
The present invention discloses orthodontic treatment planning which enables designing the desired smile line with the help of a computer workstation.A new lip trace feature enables cutting out the portion of a photograph corresponding to the area inside the lips. The 3D model of the teeth is then completely visible when overlaid with the facial photograph.One can use this feature to superimpose the patient photo over the 3-D model of the teeth to see how much intrusion or extrusion is needed to design the smile line.Three dimensional model of dentition obtained by scanning of teeth along with the patient's two dimensional facial photograph is used to design the desired smile line for the patient by means of software instructions in the workstation.
