Design software is used to virtually construct the finished appliance on a model in three dimensions according to the technician’s specifications. Within the software, virtual teeth are selected to be replaced with artificial teeth. The model is surveyed to determine the best path of insertion for the final appliance in three dimensions.
Then the design proceeds using the most of the same steps previously performed with analog models, except without using manual equipment like surveyors or pencils. In the case of partial dentures, clasps are 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 and retain stability. Other things, such as modifying the gingival sculpting and diastema creation, can be added or changed to improve the desired outcome.
Once the technician is satisfied with the design, files containing the design instructions are used to print 3D models or to manufacture the final restoration of digital dentures.
