The invention belongs to an orofacial cleft external
nose non-traumatic orthopedic treatment method in the medical field, and particularly relates to a digital preparation method for an orofacial cleft external
nose deformity orthopedic appliance. The method is characterized by at least comprising the following steps: 1), acquiring three-dimensional data of the face of an orofacial cleft patient; 2) reconstructing a digital model for the face of the orofacial cleft patient in a three-dimensional manner; 3), constructing a digital model for the external
nose orthopedic appliance according to a three-dimensional
face model, wherein the digital model comprises a nose support C, a bridge body B and a base support A; 4), constructing
solid models for the nose support C, the bridge B and the base support A through a rapid proto-
typing technology according to the nose support, the bridge body and the base support made through the digital module; and 5) clinically applying the
solid model of the external nose
orthopedic appliance. According to the method, an existing pure manual operation is changed into computer controlled
automatic processing, so that the manufacture precision of the appliance is guaranteed. Therefore, the standard and rapid
individualized treatment method is provided for the orofacial cleft patient, and the clinical popularization and application of the technology can be promoted.
