Technical Field

The invention relates to the technical field of planting, in particular to a digital all-in-one guide plate for edentulous jaw planting and a manufacturing method thereof.

Background

With the development of computer-aided design/computer-aided manufacturing (CAD/CAM) technology in the field of oral implantation, the application of the digital static guide plate in the edentulous jaw implantation surgery is more mature. Edentulous jaw implantation planning typically requires three guide plates including a radiation guide plate, a retention pin guide plate, and a surgical guide plate. For an old denture without metal parts, a radiation blocking point can be added to serve as a radiation guide plate; for old dentures containing metal parts, it is necessary to copy the denture first and then to add a radiation-blocking point on the copied denture to serve as a radiation guide. The retention guide typically includes an occlusal surface and a base configuration that conforms to the radial guide, and a guide tube for guiding the preparation of the retention track. The surgical guide also contains occlusal and base configurations that conform to the radiation guide, as well as a guide for cavity preparation and implant implantation.

In the traditional digital design process, the three guide plates are independent; in application, firstly, a CBCT (cone beam computed tomography) is shot by using a radiation guide plate manufactured based on an old denture for implantation planning, then a retention nail guide plate and a surgical guide plate are designed, the retention nail guide plate is reset to the same position as the radiation guide plate by using the same occlusal surface or a preoperatively prepared silicone rubber occlusion record in operation, and the surgical guide plate is reset to the same position as the retention nail guide plate by using the same retention nail position.

Due to the step effect of the 3D printer, the shapes of the occlusal surfaces of the retention nail guide plate and the surgical guide plate which are independently printed are not necessarily identical, and are not necessarily identical to the occlusal surface of the old false tooth, and the deviation generated in the printing process can cause the guide plates to be not matched. At least two guide plates need to be printed, so that the material cost is high; poor post-treatment of old dentures with added radiation-blocking points can lead to the accumulation of plaque, soft scale, etc. around the points, which is not conducive to the maintenance of oral hygiene. In addition, the risk of the guide plate breaking in use is high due to the strength problem of the resin material itself.
