the data set as known in the art based on the digital model the process generates virtual veneers 14 a 3 d physical wax model is created from the virtual veneer 16 the wax is used to create negative mold 18 porcelain or dental composite is then cast into a negative to form veneers 20 other dental materials besides porcelain and dental composite may be used to form the materials depending on the material properties desired in the veneer a rapid prototyping machine such as a stereolithography apparatus sla is used to make a 3 d virtual model of the dentition with veneers in place 22 a removable appliance is made from sla virtual model 24 the dental template appliance can be formed and can be made from a thin shell material the polymeric appliance is preferably formed from a thin sheet of a suitable elastomeric polymeric such as tru tain 0 030 in thermal forming dental material tru tain plastics rochester minn 55902 usually no wires or other means will be provided for holding the appliance in place over the teeth in one implementation the appliance is made from a thin material such as pc15 polycarbonate 0 015 inch available from align technology inc veneers are then mounted on the patient 39 s teeth either separately or as a group by loading the veneers into the template that secures the veneers into place for confirmation of esthetics 26 in one embodiment.
