Problems solved by technology

This method has some disadvantages: First, the maxillary bone defect causes the patient's oral and nasal cavity to perforate, so the impression is taken at the front end of the patient's airway, and the patient feels uncomfortable during the operation and there is a risk of aspiration of the impression material into the airway risk
Secondly, this method cannot completely remove the undercut of the defect site.
In addition, scar contracture and radiation therapy after maxillary tumor resection often lead to a reduction in ...

Embodiment 1

[0027] The preparation gel-metal composite prosthesis processing technological process provided by the present invention, such as figure 1 As shown, it specifically includes the following steps: 1) acquiring the image data of the patient's craniomaxillofacial region and defect (right cheek);

[0028]Wherein, the acquisition method is a CT scanning method. In order to make the gel-metal composite prosthesis obtained in step 5) suitable for the patient's craniomaxillofacial region and defect (right cheek), the image data obtained in this step was also used to prepare a three-dimensional solid model of the patient's craniomaxillofacial region①, specifically The steps are: use a rapid prototyping machine (purchased from Shanghai Fuqifan Electromechanical Technology Co., Ltd. model HTS-300 rapid prototyping machine), adopt the melting extrusion molding method provided in the manual of the rapid prototyping machine, and obtain the patient's craniomaxillofacial The three-dimensional...

Abstract

The invention discloses a complex-shaped gel-metal composite prosthesis and a manufacturing method thereof. The prosthesis consists of a silicon rubber jacket and a three-dimensional bracket inside the silicon rubber jacket, wherein the silicon rubber jacket and a titanium mesh three-dimensional structure are simulated and manufactured through the assistance of a computer. The prosthesis can be completely attached to soft and hard tissue defects, has a good edge sealing and fixing effect, has certain supporting strength on the basis of recovering the attractive appearance of a patient, can resist physiological movement of an oral cavity jaw face, is difficult to deform, and provides a new direction for solving the problems of heavy weight, low elasticity, high hardness, a large number of side effects and the like of the conventional prosthesis.

Description

technical field [0001] The invention belongs to the field of maxillofacial defect repair, in particular to a gel-metal composite prosthesis with complex shape and a preparation method thereof. Background technique [0002] Jaw defects are usually caused by tumor resection or trauma, which will cause severe mastication, speech, swallowing functions and facial deformities in patients, and postoperative defect repair is necessary. The special position and special tissue structure of the maxilla make the application of surgical reconstruction methods such as bone grafting and tissue flap transfer very difficult. So far, oral and maxillofacial surgeons have not been able to establish a very mature surgical method for maxillary reconstruction, and maxillary defects still rely on the repair of prostheses. [0003] The repair of maxillofacial defects is a series of treatment processes, which mainly include the production and use of palatal guards, temporary stoppers and formal pros...
