Problems solved by technology

However, all kinds of cleft lip and palate external nasal appliances at home and abroad are completely designed based on the subjective experience of doctors, and are made by hand. The treatment is random, the production accuracy is unstable, and it is difficult to predict the treatment process and effect.
In my country, only a few cleft lip and palate treatment specialist centers can carry out this treatment, which seriously limits the promotion and application of this technology in my country.

Embodiment Construction

[0028] The technical solution adopted in the present invention is: a digital preparation method of a cleft lip and palate external nasal appliance, and its specific technical means are as follows:

[0029] 1) Acquisition of 3D face data of children with cleft lip and palate: 3d MD Face visible light 3D scanner is used to scan the face of children with cleft lip and palate directly; The collaborative camera system takes synchronous photography on the face of the child, generates a continuous point cloud, and obtains two digital images of the face of the child with cleft lip and palate. After bundle adjustment, image processing and matching, and digital calculation, the external nose-cleft lip 3D data of the face;

[0030] 2) Three-dimensional reconstruction of the facial digital model of the child with cleft lip: the original three-dimensional data of the child's face obtained in step 1 was retrieved, and unnecessary noise and bad points were removed through three-dimensional ...

Abstract

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.

Description

technical field [0001] The invention belongs to the medical field and relates to a non-traumatic orthopedic treatment method for congenital cleft lip and palate external nasal deformity, and in particular relates to a digital preparation method for a cleft lip and palate external nasal deformity appliance. Background technique [0002] Cleft lip and palate is one of the most common congenital maxillofacial defects. The incidence rate in China accounts for about 700% of the birth rate. According to statistics, there are at least 2.4 million cleft lip and palate patients in my country, and about 70% of them are accompanied by obvious deformity of the external nose. Early preoperative correction of cleft lip and palate external nasal deformity in neonatal period is one of the hottest researches in this field at present. For the shape of the healthy side of the child’s external nose, use the artificially designed external nasal appliance to correct the shape of the deformed side...
