Abstract: Systems and techniques for designing a digital dental matrix with improved interproximal contacts are disclosed including generating a digital three-dimensional model of a future dental anatomy of a patient, the future dental anatomy representing an intended shape of at least one tooth of the patient, selecting one or more pairs of adjacent teeth in the 3D model, for each selected pair of teeth, determining a location and orientation in the interproximal space of the adjacent teeth to insert a digital 3D geometry having one or more initial parameters, and inserting the digital 3D geometry at the determined location and orientation.

Abstract: A dental model includes a model dental arch and a plurality of model teeth. The model dental arch includes a first member including a plurality of first openings therethrough, and a second member including a plurality of second openings extending therethrough. The plurality of first openings of the first member and the plurality of second openings of the second member are aligned to each other in a one-to-one correspondence. Each model tooth from the plurality of model teeth includes a tooth portion and a connecting portion extending from the tooth portion. The tooth portion of each model tooth is at least partially and slidably received in a respective first opening from the plurality of first openings. The connecting portion of each model tooth is at least partially received in a respective second opening from the plurality of second openings and detachably retained in the respective second opening.
