Description

Technical Field

[0001] The utility model relates to the technical field of oral implant surgery, in particular to a positioning guide plate used in oral implant surgery. Background Art

[0002] The success of an oral implant surgery depends on the precise implant placement guided by restoration. The implantation of conventional free teeth often depends on the experience of the surgeon and needs to be repeatedly verified during the operation. For a novice implanter, it often takes more time and cannot achieve accurate implant placement. Digital technology is the fastest-growing and most cutting-edge high-tech in the oral field. Digital imaging, digital diagnosis, digital design, digital impressions, digital processing and manufacturing, and digital assisted surgery are increasingly being used in the oral multidisciplinary diagnosis and treatment process, realizing a precise, efficient, minimally invasive, repeatable process, and predictable results diagnosis and treatment model, which is the trend and inevitable trend of future oral development. Therefore, in order to achieve the precise implantation of implants, digitally designed and printed implant surgical guides came into being and have been rapidly developed.

[0003] At present, implant surgical guides are relatively mature and are increasingly used in primary hospitals. However, although implant surgical guides can achieve precise implantation, their operation process is relatively complicated. Implantation often depends on the experience of the surgeon and needs to be repeatedly verified during the operation. For a novice, it often takes more time, and cannot obtain accurate implant implantation. It also requires a special instrument tool box, which places high demands on the doctor's operating ability. It not only increases the cost of patients, but also increases the cost of cleaning and disinfection of instruments in hospitals, as well as the loss of instruments. Therefore, it is necessary to propose a positioning guide for oral implant surgery.

[0004] In response to the above problem, a Chinese patent announcement with announcement number CN220275742U discloses a positioning guide for oral implant surgery, the key technical points of which are: it includes a crescent plate adapted to the curvature of the gums, and a fixing frame fixed on the teeth, the outer side of the crescent plate is fixedly connected to the inner side of the fixing frame, the fixing frame is provided with a plurality of mounting holes for drill bits to enter, a sleeve for assisting drill bit positioning is provided in the mounting hole, and a groove is provided on the side wall of the sleeve for facilitating the insertion of the drill bit; a lead screw is movably connected to the top of the crescent plate, the lead screw is threadedly connected to a vertical rod, and the vertical rod is hinged to the top plate at one end away from the crescent plate.

[0005] In actual operation, it is found that the above scheme still has at least the following defects: the vertical rod and top plate of the guide plate make the guide plate as a whole larger, which is not easy to place in the oral cavity and to remove after surgery, which is rather troublesome. Therefore, we propose a positioning guide plate for oral implant surgery to solve the above problems. Utility Model Content
