Problems solved by technology

[0003] Because orthognathic surgery requires high clinical experience and surgical skills of the surgeon, and most of the operations are performed in the mouth of the patient, the operation is extremely difficult, and the surgical field of view is not well exposed, so the operation demonstration teaching is difficult Very high, talent training cycle is long
At present, for the teaching of orthognathic surgery, there is a lack of advanced surgical demonstration teaching molds.

Embodiment 1

[0052] Such as Figure 1-Figure 11 As shown, a set of teaching molds for orthognathic surgery disclosed in this embodiment includes an upper jaw mold 1 and a lower jaw mold 2 .

[0053] Such as Figure 1-Figure 3 As shown, the maxillary mold 1 includes a skull module 11 , a maxilla module 12 and an upper dentition module 13 .

[0054] The maxillary module 12 is located between the skull module 11 and the upper dentition module 13 , the upper side of the upper jaw module 12 is connected with the skull module 11 , and the upper side of the upper dentition module 13 is detachably connected with the upper jaw module 12 .

[0055] There are many detachable connection methods, such as threaded connection, adhesive bonding, etc., which can be selected by those skilled in the art according to needs. It is worth noting that this embodiment also provides two new detachable connection methods, as follows:

[0056] Mode 1, the maxillary module 12 is connected to the upper dentition mod...

Embodiment 2

[0081] In this embodiment, on the basis of Embodiment 1, the mandibular distal bone segment module 21 is divided into two parts, the mandibular distal bone segment main module 26 and the chin module 25, as Figure 12 shown.

[0082] The position of the chin module 25 can be adjusted front, back, left, and right relative to the main module 26 of the distal mandibular bone segment.

[0083] In particular, the chin module 25 is slidably connected with the main module 26 of the distal mandibular bone segment. Such as Figure 13 As shown, a cross-shaped chute 261 can be set at the position where the main module 26 of the distal mandibular bone segment is connected to the chin module 25. There is a suitable slider on the chin module 25, and the slider is installed in the cross-shaped chute. 261 in.

[0084] After the relative position of the chin module 25 and the mandible distal bone section main module 26 is adjusted in place, the chin module 25 and the mandible distal bone sec...

Embodiment 3

[0092] The difference of this embodiment in Embodiment 1 or Embodiment 2 is that: the left side and the right side of the mandibular distal bone segment module 21 are suitable for the right mandibular proximal bone segment module 22 and the left mandibular proximal bone segment module 23. The matching groove, the right mandibular near-cardiac segment module 22 and the left mandible near-cardiac segment module 23 are installed in the grooves, so that the right mandible near-cardiac segment module The surface of the module 22 , the proximal bone segment module 23 of the left mandible, and the distal bone segment module 21 of the mandible are flush. Optionally, the right mandibular proximal bone segment module 22 and the left mandibular proximal cardiac bone segment module 23 are divided into two parts, the front bone segment 231 and the rear bone segment 232, such as Figure 15 , Figure 16 shown.

[0093] A plurality of pin holes 4 or pins 3 are arranged along the front-back ...

Abstract

The invention relates to an orthognathic surgery teaching mold and a use method thereof, the orthognathic surgery teaching mold comprises an upper jaw mold and a lower jaw mold, the upper jaw mold comprises an upper jaw bone module and an upper dentition module, and the upper dentition module is detachably connected with the upper jaw bone module; the lower jaw mold comprises a lower jawbone module and a lower dentition module, and the lower dentition module is detachably connected with the lower jawbone module; particularly, the upper dentition module is connected with the upper jawbone module in an inserted mode or in a magnetic attraction mode, and the lower dentition module is connected with the lower jawbone module in an inserted mode or in a magnetic attraction mode. The invention provides a surgical operation mold for medical students or doctors, so that the medical students and the doctors can more vividly and intuitively understand the anatomical structure of the jaw bone, the bone cutting part of the orthognathic surgery, the moving direction and the moving effect after the jaw bone is cut open, the firm internal fixing part of the jaw bone and the operation method, and the like, and the deep understanding of the medical students and the doctors on the orthognathic surgery can be improved, the training period of orthognathic surgery specialists is shortened, and more qualified orthognathic surgery specialists can be cultivated.

Description

technical field [0001] The invention relates to the technical field of medical teaching, in particular to a set of teaching molds for orthognathic surgery and a method for using the same. Background technique [0002] Dentofacial deformities (dentofacial deformities) refer to the abnormal facial shape and occlusal disorder caused by the maladjusted growth and development of the jaws. At present, there are more than 20 million patients with dentofacial deformities in China. This kind of deformity needs to be corrected by orthognathic surgery. Orthognathic surgery is to correct the dento-maxillofacial deformity caused by abnormal development of facial bone or jaw bone or disordered relationship between teeth and bone structure. [0003] Because orthognathic surgery requires high clinical experience and surgical skills of the surgeon, and most of the operations are performed in the mouth of the patient, the operation is extremely difficult, and the surgical field of view is no...
