Abstract:
1. A manufacturing process of digitally designed removable dental prostheses, wherein a digital relief process is performed in areas where a lattice would be placed, comprising the following steps: A) scanning a mould produced from an impression taken of a patient's mouth, said scanning generating a digitized mould; B) transmitting a file produced by said scanning to a computer where a design is performed, said file containing a first three-dimensional representation of said digitized mould; C) digitally designing pieces and components of a removable dental prosthesis, making a digital design of said pieces and components on a representation of said digitized mould; D) giving thickness to said digital design of said pieces and components; E) producing and transmitting said file to a manufacturing equipment of metal pieces by means of sintered powder whereto a high-energy ray is applied after performing said digital design of said removable dental prosthesis; F) digitally calculating an insertion axis; G) digitally paralleling said removable dental prosthesis, said digitally designing pieces and components of said removable dental prosthesis comprises using a major connector, a minor connector, a lattice, a stop, a clamp, a lingual bar, a bristle and pearls; H) extruding said pieces and components; I) smoothing sharp edges of said pieces and components; J) eliminating a superposition of said pieces and components; and K) converting a closed continuous and connected surface to a three-dimensional representation, further characterized in that a plane is disposed parallel to a palate when said digitally calculating said insertion axis, said palate has a greatest number of insertions on said removable dental prosthesis at a same height, said insertion axis is perpendicular to said plane.
