Abstract:
1. A method for forming a dental mold, the method comprising: (a) scanning an existing dental structure to generate a three-dimensional first digital model of the existing dental structure; (b) modifying the first digital model of the existing dental structure to generate a three-dimensional second digital model of a planned dental structure, the planned dental structure having spatial surface contours different from those of the existing dental structure; (c) generating a three-dimensional third digital model corresponding to a negative of the second digital model, wherein (d) digitally sectioning the solid volume of the third digital model into two or more sub-volumes, thereby defining at least one buccal model portion of the third digital model and at least one lingual model portion of the third digital model such that the buccal model portion and the lingual model portion share at least one common interfacial surface in the third digital model; and (e) creating a dental mold comprising at least one buccal mold portion and at least one lingual mold portion, wherein
