Description
Technical Field
The invention belongs to the technical field of dental implantation, and particularly relates to a novel dental implantation guide adaptive to a digital guide plate.
Background
Dental implant surgery involves preparation of an implant cavity and implantation of an implant. In the process of preparing the cavity, the digital static guide plate can be used for guiding the drill needle in cooperation with the collar of corresponding size or the pressing plate in the operation tool box, and the drill needle in the stage is constrained by the rigidity of the collar or the pressing plate, so that accurate cavity preparation is facilitated. In the process of implanting the implant, the implant cannot be in contact with the inner wall of the guide member such as the collar or the guide tube due to the protection of the surface of the implant, and the guide plate starts to guide the implantation process only when the adapter connected above the implant contacts the inner wall of the guide member. However, almost all implant systems have an inherent, non-guiding structure, including the implant and the carrier above it, which is particularly evident in anterior dental implant procedures when the length of the "non-guiding structure" is greater than the distance the guide plate is guiding. In addition, in order to ensure that the implant has sufficient initial stability, the diameter of the prepared cavity is generally smaller than the diameter of the implant, and at this time, insufficient guidance or even lack of guidance may more easily cause the adaptor to tilt in the guide plate, causing implant deviation of the implant. And the large inclination can lead the adapter not to smoothly pass through the guide part, so that the further operation is influenced, at the moment, the guide plate can only be taken down, the implantation precision is not controllable by bare-handed implantation through experience, and the original purpose of using the guide plate is overcome.
