Problems solved by technology

[0003] In the prior art, after the condyle is moved to the mandibular fossa through surgical experience, the osteotomized area is repaired with bone grafts. In this process, osteotomy errors are prone to occur, and it is often impossible to make the remaining teeth of the patient bite the upper and lower jaws. relationship stabilized

Embodiment Construction

[0027] figure 1 It is a digital assisted joint reset according to an embodiment of the present application Schematic flow diagram of the plate fabrication method apparatus. This embodiment provides a digital assisted joint reset The method for making the board generally may include the following steps:

[0028] Step 100, obtain dentition three-dimensional model data through intraoral optical scanning and model reconstruction;

[0029] Step 200, using cone-beam CT to photograph the patient's craniomaxillofacial region, and obtaining cone-beam CT data of the patient's oral cavity;

[0030] Step 300, importing the patient's CT data into the surgical design software, reconstructing the patient's maxillary and mandibular parts, and adjusting the patient's natural head position according to the patient's orbito-auricular plane;

[0031] Import the three-dimensional model data of the dentition into the surgical design software, and replace the reconstructed CT data with the thr...

Abstract

The invention discloses a digital auxiliary joint reduction occlusion plate manufacturing method and a joint reduction occlusion plate, and relates to the field of oral and maxillofacial surgery. According to the method, a full-digital process is adopted, namely, digital equipment is used in the whole data acquisition, design and manufacturing processes, so that science and accuracy in the processare ensured, and a personalized joint reduction occlusion plate can be obtained. The invention provides a better way to treat a patient who has dislocation of condyle process at the front and upper part of an articular nodule, displacement of the jaw bone and occlusion mistakes, so that operation efficiency is improved. According to the invention, a normal temporal-mandibular joint on one side can be anticipated, retained and even recovered in a digital mode before an operation, and the condyle process reduction occlusion plate stably manufactured by the occlusion relationship of the upper and lower jaw dentition on the side is applied to an operation, so that the osteotomy error of fibula reconstruction mandible is reduced. An intermaxillary traction device can be worn after an operation, the lower jaw can gradually return to the median position after several days, and even the possibility of postoperative temporal-mandibular joint recurrence is reduced.

Description

technical field [0001] This application relates to the field of oral and maxillofacial surgery, in particular to a digital assisted joint reduction Plate making method and joint reset plate. Background technique [0002] In some patients, due to oral and maxillofacial cysts and tumors, the proportion of the joint space is out of balance. In severe cases, the condyle dislocated above the front of the joint tubercle, the jaw shifts, and leads to dislocation. This phenomenon. For this phenomenon, mandibular reconstruction and joint reduction surgery are generally used for treatment. In the oral surgery in which part of the patient's mandible is amputated during mandibular reconstruction surgery, the osteotomized area needs to be repaired by grafting bone, and the other side of the temporomandibular joint needs to be restored to normal, and at the same time, the upper and lower jaw bite of the patient's remaining teeth must be corrected. relation. [0003] In the prior ...
