Abstract

Presented herein are methods, systems, devices, and computer-readable media for improving dental prosthesis robustness. Embodiments include systems, methods, and computer readable media for choosing a support point configuration for a prosthesis optionally based on robustness of the support point configuration, where the support points in the support point configuration are located on the inner surface of the prosthesis away from the marginal edge. Additional embodiments include determining at least two candidate support point configurations, wherein each candidate support point configuration may optionally be generated based on a configuration of seed positions. One of the candidate support point configurations may optionally be chosen based on a robustness rating. The chosen configuration of support points may optionally be exported as a surface, a milling path, etc. and may be used in the manufacturing of the prosthesis. Other embodiments include a prosthesis, such as a crown, coping, or bridge, that includes plurality of support points that provide support between a prosthesis and the prepared tooth, and those support points are positioned on the inner surface of the prosthesis away from the marginal edge and / or away from the top area of the inner surface of the prosthesis.
