Novel dental implant guider adaptive to digital guide plate

Abstract

The invention discloses a novel dental implant guider adaptive to a digital guide plate. The novel dental implant guider comprises a scissor-shaped guiding body composed of two guiding rods, a holding ring is formed on the outer side of one end of each guiding rod, a semicircular guiding gasket is arranged on the inner wall of the other end of each guiding rod, a sliding piece matched with the guiding gasket is arranged in each guiding gasket, a linkage mechanism is installed in the section, close to the corresponding guiding gasket, of each guiding rod, a control switch of each linkage mechanism is located on the outer wall of the corresponding guiding rod, a driven mechanism of each linkage mechanism is connected with the corresponding sliding piece so that the sliding piece can vertically ascend and descend in the guiding gasket, and the inner wall of each guiding gasket is further detachably connected with an adaptive piece matched with the guiding gasket. When a guide body is closed and clamped, the two guiding gaskets, the two sliding pieces and the two adaptive pieces are spliced to form a circular ring shape. The guider is used in cooperation with the implantation guide plate, the guide height of the implantation guide plate can be effectively increased, the guide precision in the early stage of implantation is guaranteed, and therefore the implant implantation error is reduced.

Description

technical field [0001] The invention belongs to the technical field of dental implantation, and in particular relates to a novel dental implantation guide adapted to a digital guide plate. Background technique [0002] Dental implant surgery involves preparation of the implant cavity and placement of the implant. In the process of cavity preparation, the digital static guide plate can be used to guide the drill needle with the corresponding size of the collar or the pressure plate in the surgical tool box. The drill needle at this stage is rigidly constrained by the collar or pressure plate, which helps to achieve Accurate cavity preparation. In the process of implant placement, due to the protection of the implant surface, the implant cannot have any contact with the inner wall of the guide parts such as the collar or catheter. Only when the adapter connected above the implant contacts the inner wall of the guide part, The guide plate begins to guide the implantation proc...

Problems solved by technology

However, almost all implant systems have an inherent non-guiding structure, including the implant and the carrier above it. When the length of the "non-guiding structure" is greater than the distance of the guiding effect of the guide plate, the guide plate is inserted The initial stage of the can not provide effective guidance, this problem is particularly evident in the anterior implant surgery

In addition, in order to ensure sufficient initial stability of the implant, the diameter of the cavity preparation is usually smaller than the diameter of the implant. At this time, the lack of guidance or even the lack of guidance will more easily cause the adapter to tilt in the guide plate, causing implant deviation

And a large inclination may prevent the adapter from passing through the guiding parts smoothly, which will affect further operations. At this time, the guide plate can only be removed and planted by hand based on experience. The implantation accuracy will be even more uncontrollable, which violates the original intention of using the guide plate
