Problems solved by technology

The key technologies of this type of navigation system are three-dimensional visualization of clinical images of patients, registration technology and spatial positioning technology, but the current navigation system can only present the dynamic anatomical structure of the operation area on another display screen, and the observation target of the surgeon needs to be Switching back and forth between the patient's mouth and the display screen distracts the operator's attention and increases the complexity of the operation

Abstract

The invention discloses a mixed reality-based oral implant navigation system, wherein the system includes: an image processing unit (001), which is used for three-dimensional reconstruction of images obtained before operation; an image acquisition unit (002), which uses The image matching, positioning and navigation unit (004) enables the preoperative image processed by the image processing unit (001) and the intraoperative image collected by the image acquisition unit (002) to be real-time fused, and the fused image is delivered to the display unit (005). The system provided by the invention can enable the operator to understand the anatomical structure of the patient's planting site more clearly and intuitively, can perform the operation accurately, shorten the operation time, and improve the success rate of the operation.

Description

technical field [0001] The invention relates to the field of oral surgery instruments, in particular to a mixed reality-based oral implant navigation system. Background technique [0002] The theory of osseointegration discovered in the 1960s opened a new era in the application of dental implant technology to repair dentition defects. With the development of more than half a century, oral implant technology has become a routine technology for tooth restoration and has been widely used in clinical practice. [0003] The positioning of the implant in the alveolar bone is the key to ensure the success of osseointegration. The anatomy of the alveolar bone and soft tissue in the oral cavity is diverse in the population. Sufficient bone mass should be ensured around the implant, and the position and direction of the implant should conform to the principles of biomechanics and aesthetics. Therefore, designing the position and direction of the implant in the jawbone is a difficult...
