Occlusal splint, digital design method of occlusal splint and 3D printing production method

Abstract

The invention relates to the field of oral medicine, in particular to an occlusal splint, a digital design method of the occlusal splint and a 3D printing production method. By adopting the virtual design method of the occlusal plate of the present invention, the digital model combined with the virtual frame can be formed accurately through the scanning of the upper and lower jaw models and the physical frame. The consistency of the virtual frame ensures that the positioning of the digital upper and lower jaw models on the virtual frame is exactly the same as that of the physical model on the physical frame, and the design of the occlusal plate is performed on the high-precision digital model that includes the virtual frame , not only can give full play to the convenience of digital design, but also can adjust the occlusion of the initially designed occlusal plate through the virtual frame, and further improve the accuracy of the designed occlusal plate.

Description

technical field [0001] The invention relates to the field of oral medicine, in particular to an occlusal splint, a digital design method of the occlusal splint and a 3D printing production method. Background technique [0002] The dysfunction of the oral and maxillofacial system is one of the common problems in the field of oral medicine, which will cause problems in the patient's teeth, periodontal, occlusal, maxillofacial muscles, and the patient's spirit, work and life. Therefore, effective occlusal treatment should be given to patients in time to improve the coordination between the various parts of the stomatognathic system and restore the normal function of the stomatognathic system. Occlusal splint treatment is a common method of occlusal treatment. Because of its reversible and non-injury advantages, it is widely used in the treatment of occlusal trauma, temporomandibular joint disorder, bruxism and other oral and jaw diseases. It is also used as an auxiliary treatme...

Problems solved by technology

Using this method can solve the problems of single splint design, complicated procedures and inaccurate production in the treatment of temporomandibular joint disorders.

[0007] In the preparation method of the above-mentioned 3D printed occlusal splint, the occlusal splint is designed in the software. After the occlusal splint is processed, it can still be adjusted and ground in the mouth as in the patent application disclosed by the publication number CN102670340A to ensure the production The degree of matching between the occlusal plate and the patient, but the difficulty of this adjustment process is relatively high
