Embodiment Construction

[0048] The present invention will be further described below in conjunction with specific examples, but not as a limitation of the present invention.

[0049] The method of the present invention's design and making occluder model is as follows:

[0050] Perform intraoral optical scanning on patients to obtain intraoral optical scanning data, and convert them into STL format for output;

[0051] Helical CT scanning of the patient's maxillofacial area to obtain DICOM data;

[0052]Import the spiral CT scan DICOM data into the Mimics modeling software (provided by Materialize Software, Belgium), and reconstruct the three-dimensional model of the soft and hard tissue of the patient's cranio-maxillofacial tissue, and output it in STL format; the three-dimensional model data obtained by modeling the spiral CT Design a personalized composite model with the intraoral scan data through the reverse design software Geomagic Studio; the specific steps are as follows:

[0053] Step a1. I...

Abstract

The invention provides a prosthesis making method based on digital design and numerical control machining, which comprises the following steps: a blocker model is digitally designed based on multi-source data, the blocker model data is obtained, and the blocker model is obtained by a numerical control forming device; the data of occluder model is obtained by removable partial denture stent designsoftware, and the stent model of prosthesis is obtained by numerical control forming device. The prosthesis scaffold model is placed on the occluder model, and the occlusal test is carried out. The prosthesis is obtained by filling glue and packed in a box. The invention is based on multi-source data fusion modeling, obstructor model is obtained by reverse design, and digital prosthesis is obtained according to the obstructor model, which reduces clinical operation difficulty of obstructor impression, shortens clinical production time, and reduces patient discomfort. The obstructor model and prosthetic stent model were made by digital technology, which can shorten the operation time of clinical and technical room, shorten the number of patients, reduce the difficulty of prosthesis and improve the work efficiency.

Description

technical field [0001] The invention relates to a method for manufacturing medical equipment, in particular to a method for making a prosthesis based on digital design and numerical control processing. Background technique [0002] Patients with maxillary defects who require obstructor prostheses to block oronasal communication improve their pronunciation, chewing and swallowing problems. Therefore, it is very important to make occluder prosthesis with good retention, good sealing and reasonable occlusal relationship. During the fabrication process, whether the anatomical shape of soft and hard tissues in the patient's mouth can be accurately obtained will directly determine whether the final prosthesis can achieve a successful therapeutic effect. The production of traditional models relies on the clinical experience of specialists in maxillofacial restoration. Through complex steps and a variety of impression materials to obtain the structure of the patient's mouth, the op...
