TECHNICAL FIELD
[0001] The utility model relates to the field of edentulous jaw implantation repair technology, in particular to a positioning device for edentulous jaw implantation repair. BACKGROUND
[0002] With the popularity and application of digital technology in the field of dentistry, obtaining a digital impression of the dentition through digital intraoral scanning technology has become an essential part of digital intraoral scanning equipment. Most of the digital intraoral scanning equipment is based on optical principles, such as blue light-emitting diode technology and blue laser technology. Multiple single images are spliced together, and then a continuous image stream is collected. Unlike scanning of natural dentition, scanning of dental implants requires the use of a scanning rod to achieve three-dimensional positioning of the implant in the bone. During intraoral scanning, the scanning rod is connected to the implant, and the scanning rod represents the three-dimensional position of the implant in the patient's mouth. The scanning rod and the surrounding dentition or soft tissue are captured, and the spatial position of the implant in the mouth is obtained. The technical level of intraoral scanning includes two steps: first, three-dimensional imaging is used to collect three-dimensional data points of the tooth surface at a single position; then, during the movement of the intraoral camera, the three-dimensional data collected at different positions are continuously superimposed, and finally a complete three-dimensional data model is formed. Intraoral scanning includes scanning the upper dentition, scanning the lower dentition, and scanning the upper and lower occlusion relationship. In the case of edentulous jaw implantation repair (including upper edentulous jaw, lower edentulous jaw, and upper and lower edentulous jaw), although intraoral scanning technology performs well in many clinical situations, it is difficult to implement intraoral scanning when scanning the three-dimensional position of the implant in the edentulous jaw implantation repair. Due to the loss of natural teeth, the original occlusion relationship is lost, and therefore it is not possible to scan the patient's correct occlusion relationship. How to apply intraoral scanning to obtain the occlusion relationship of edentulous jaw patients is a clinical difficulty.
[0003] To this end, some scholars at home and abroad have attempted to add auxiliary scanning devices to help improve the accuracy of intraoral scanning and improve scanning accuracy. However, there are inevitable problems. Some scholars expect the auxiliary device to be fixed at the bottom of the scanning rod, but the device is in close contact with the soft tissue, which affects the scanning of the soft tissue and has a certain impact on subsequent design. Some scholars expect the scanning rod and the auxiliary device to be connected together, but due to the inability to adjust the height according to the actual situation, the effect is not obvious
[0004] Based on this, a positioning device for edentulous jaw implantation repair is now provided, which can eliminate the drawbacks of existing devices. UTILITY MODEL CONTENT
