Once the three-dimensional dental restoration is fabricated within the computer software through the use of virtual models, the operator is able to select the characteristics and desired specifications of the denture framework.
Technicians can customize the denture’s overall appearance including tooth shape, tooth size, tooth arrangement, tooth position, tooth color, gingiva color, uniform thickness of the baseplate, and other parameters for viewing before the final restoration is ever manufactured.
With partial framework design, clasps may be placed virtually with respect given to undercuts. Tissue stops and major connectors are designed for wider connectors which allow the framework material to be thinner while improving stability.
Other parameters, such as modifying the gingival sculpting and diastema creation, can be added or changed to improve the desired outcome before the framework or baseplate is made.
For totally edentulous cases, mockups of proposed dentures are 3D-printed, allowing the dentist to conduct a try in appointment. This try in allows the bite relationship to be verified and refined, similar to the familiar wax try in phase used with traditional dentures. The try in also allows the dentist an opportunity to improve the tooth arrangement and lip support for the ideal appearance.
Once the dentist is satisfied with the design, files containing the revised design parameters are used by the denture technician to manufacture the final dentures, either by additive 3D printing or subtractive computer-aided manufacturing methodology.
