Whole-course digital combined guide plate suitable for full-mouth implant surgery

Abstract

The invention provides a whole-course digital combined guide plate suitable for a full-mouth implant surgery. The whole-course digital combined guide plate comprises a digital positioning guide plate, a digital osteotomy guide plate, a digital end guide plate and positioning nails, and further comprises a digital temporary tooth which is retained after being connected with the digital osteotomy guide plate. The positioning guide plate and the osteotomy guide plate are connected in a combined bolt way mode, the positioning nails do not need to be taken out in the whole process, and guide plate positioning does not need to be conducted again in the subsequent process after initial positioning is completed throughout the process, so that accuracy of digital guidance on implant surgery is guaranteed; and meanwhile, immediate wearing of temporary teeth can be achieved, and surgery time is saved to a great extent.

Description

technical field [0001] The invention relates to the technical field of oral instruments, in particular to a full-range digital combined guide plate suitable for full-mouth implant surgery. Background technique [0002] Full mouth edentulous or severe dentition loss greatly impairs the quality of life and mental health of the elderly. Immediate restoration of full mouth implants can effectively and fundamentally solve the problem that edentulous patients cannot eat normally. It is efficient and Greatly improved the quality of life of the edentulous jaw. Traditional implants mainly rely on the accumulated experience of doctors. The operator cannot accurately control the direction of the implant during the operation, which will increase the risk of damaging adjacent important structures during the operation, and even increase the difficulty of later repairs. Digital technology uses preoperative CT data to design planning, analyze the bone mass and bone density of the implant s...

Problems solved by technology

The existing digital guides for full-mouth implantation mainly have two problems: 1. The positioning guide, osteotomy guide, and implantation guide currently used for full-mouth digital implantation are three independent guides. After the positioning guide is used to prepare the positioning hole, When installing the osteotomy guide plate and implantation guide plate, there is often a problem that the guide plate cannot be fully seated, and it takes a long time to switch during the operation. Specifically, after the positioning guide plate is positioned, the positioning hole is prepared and the positioning pin is used for positioning. , when replacing the osteotomy guide plate, you need to take out the retaining nails first, and then use the retaining nails for positioning based on the last positioning hole. The positioning holes are positioned with retaining nails, and the replacement of the guide plate and the guide plate. At the same time, it is difficult for the four positioning nails to be completely in place in four directions at the same time. It takes a long time during the operation and it is difficult to ensure that the implants input accuracy
