3D printing-based tooth-supported maxillofacial augmented reality positioning and tracking device

Abstract

The invention relates to the related field of oral-maxillofacial surgical medical apparatus and instruments and augmented reality technologies, in particular to a tooth-borne type maxillofacial augmented realitypositioning tracing device based on three-dimensional printing. The device is characterized by comprising an occlusion guide plate and a vision capture marking module, the vision capture marking module is provided with a retention body, a connection body and a replaceable vision capture mark, the occlusion guide plate is connected with the retention body, and the retention body and thereplaceable vision capture mark are integrally connected through the connection body. The tooth-borne type maxillofacial augmented reality positioning tracing device based on three-dimensional printing is simple in structure, convenient to operate, low in cost, portable and efficient, accurate positioning and dynamic visualization are achieved, the device is beneficial for the maxillofacial surgery, and the good effect is achieved.

Description

technical field [0001] The invention relates to the field of oral and maxillofacial surgical medical instruments and augmented reality technology, in particular to a tooth-supported maxillofacial augmented reality positioning and tracking device based on 3D printing. Background technique [0002] Traditional maxillofacial surgery is determined entirely by the experience and judgment of the surgeon, so the success or failure of the operation largely depends on the mastery of the local anatomical structure by the surgeon. For young doctors or cases with large local structure variations, The difficulty of the operation is greatly increased, which seriously affects the effect of the operation and even prolongs the time of the operation. [0003] With the rapid development of digital technology in oral and maxillofacial surgery, methods such as digital guide plate and surgical navigation have emerged for the positioning and tracking of intraoperative anatomical structures, but th...

AI Technical Summary

Problems solved by technology

[0004] Due to the non-linear structure of the maxillofacial region, the anatomical structure is complex and highly variable, conventional positioning and tracking technology needs to implant fixation pins in the cranial trauma, and then use related technologies for positioning and tracking, which increases surgical trauma and operation time

In addition, the positioning tracking based on the hand-made tooth support cannot satisfy the control of the consistency of the parameters and the stability of the three-dimensional coordinates, which increases the error of the visual positioning tracking. If the error is large, it may even have a negative effect on the operation.
