Description

Technical Field

[0001] The utility model belongs to the technical field of medical devices, and particularly relates to a lateral cutting drill bit for preparing oral implant cavities. Background Art

[0002] In recent years, with the development of computer-aided design software and the continuous upgrading of CBCT, intraoral optical scanners, computer-aided manufacturing, 3D printing equipment, etc., digital implant guides have been widely used in oral implant surgery. The digital implant guide in oral implant is the whole process of cavity preparation and implant placement under digital guidance, realizing the ideal three-dimensional position of the implant guided by restoration. A large number of literature studies have confirmed that the oral implant surgery guided by the guide has higher accuracy compared with the traditional implant surgery, and the application of the implant surgery guide can reduce the risk of implant surgery.

[0003] The production and use of digital implant guides involve the cooperation of doctors, patients, and designers. Each link in a series of processes such as data acquisition, implant guide design and production, and surgical operations can affect the final accuracy of the guide. With the development of information technology and the progress of data acquisition, data registration, and guide design and production software, the design accuracy of the guide has been significantly improved. Therefore, the patient's bone tissue anatomical structure and the doctor's surgical procedure are the main reasons affecting the final result. The preparation of implant cavities guided by digital guides is default to be carried out on a flat bone surface. However, in clinical practice, due to different reasons for tooth loss, tooth loss sites, and tooth loss times of different patients, the bone surface is often uneven, presenting a sloping shape or even a knife-edge alveolar ridge. A large number of clinical practices have shown that since the drill bits for preparing implant cavities all have cutting ability at the tip, when encountering a sloping or knife-edge bone ridge, the drill bit will slip, resulting in deviations in cavity preparation and implant placement.

[0004] In the current surgical process of tooth implant guided by digital technology, due to the use of instruments such as guide rings and pressing plates, on the one hand, it can effectively limit and guide the direction of the drill bit preparation channel. However, for the alveolar ridge with uneven bone surface often encountered in clinical practice, the limitation of the drill bit preparation channel direction also causes the drill bit unable to apply force to the side with greater bone resistance. This is mainly to avoid the drill bit slipping during the preparation of the channel, resulting in deviations in cavity preparation and implant placement. In the currently used implant guide tool kits, only some implant system tool kits are equipped with bone surface leveling drill bits for preliminary lateral leveling of uneven bone surfaces, but the design of all bone leveling drill bits still only has cutting ability at the tip, and it is impossible to avoid the drill bit slipping on the inclined bone surface. The bone surface leveled by the leveling drill may already have errors, and subsequent preparations based on this may still have errors. Content of the Utility Model

When preparing implant cavities on uneven bone surfaces, it will not slip or deviate, so that accurate positioning and orientation can be achieved, and the preparation of implant cavities is precise.

[0058] Example 8.

[0059] As Figure 1 and Figure 2 shown, a lateral cutting drill for oral implant cavity preparation provided by the utility model includes a drill shaft 1 and a drill shaft head 2 provided on the drill shaft 1; a plurality of helical drill ribs 3 are evenly arranged on the outer peripheral surface of the drill shaft head 2 at intervals. The drill shaft head 2 includes a helical drill bit section 21 and a helical lateral cutting drill bit section 22 integrally formed with the helical drill bit section 21. A plurality of lateral cutting grooves 23 are evenly distributed on the helical drill ribs 3 on the helical lateral cutting drill bit section 22.

[0060] The drill shaft 1 and the drill shaft head 2 have the same diameter.

[0061] Based on Embodiment 1, Embodiment 8 provides a more preferable structure for the drill shaft 1 and the drill head 2. Specifically: The drill shaft 1 and the drill head 2 have the same diameter. The drill shaft 1 makes the preparation of the implant cavity contact with the upper part of the pressing plate to achieve depth guidance. The same diameter of the drill shaft 1 and the drill head 2 can effectively ensure the accuracy of the preparation of the implant cavity.

[0062] The structure of the utility model is simple, scientifically reasonable in design and convenient to use. When preparing the implant cavity on an uneven bone surface, there will be no slipping and skewing, so that accurate positioning and orientation can be achieved, and the preparation of the implant cavity is accurate. When preparing the implant cavity on an inclined bone crest, the situation of deviation in the preparation of the cavity and the implantation of the implant due to slipping and skewing can be effectively avoided.

[0063] The side cutting drill for oral implant cavity preparation of the utility model is used based on a conventional pressing plate, and can be directly replaced with a conventional drill bit on the conventional instruments for oral implant cavity preparation for operation, without replacing other supporting equipment for oral implant cavity preparation.

[0064] For a side cutting drill for oral implant cavity preparation of the utility model, in order to realize the digital guidance of the side cutting drill, the designed guiding side cutting drill mainly has three lengths, which are the same as the lengths of the drill bits in the conventional guide plate tool box for oral implant, namely 17mm, 21mm and 25mm. Each length corresponds to 6 diameter sizes to realize the gradual preparation of the implant cavity. These 6 diameter sizes are: 1.4mm, 2.0mm, 2.2mm, 2.4mm, 2.6mm and 2.8mm, and are used corresponding to the existing pressing plates 1.4 / 2.0mm, 2.2 / 2.4mm, 2.6 / 2.8mm.

[0065] The guiding side cutting drill for oral implant cavity preparation of the utility model is mainly used before the formal guide plate tool box. The guiding side cutting drill and the general tool box share a guide ring. By preferentially using the guiding side cutting drill to realize the primary preparation of the cavity, during the preparation process, the drill bit is provided with a tip (spiral side cutting drill bit section) with a side cutting function of 5mm in length to achieve accurate positioning and guidance. At the same time, in order to avoid the lateral preparation of the cavity and damage to the internal structure of the pressing plate caused by the shaking of the drill bit. The upper part of the 5mm side cutting drill is a spiral drill part (spiral drill bit section) without a side cutting function, which can collect the autologous bone chips during the preparation process and is the part mainly in contact with the pressing plate during the reaming process, and will not damage the internal structure of the pressing plate.

[0066] After the gradual preparation of the cavity under the guidance of the side cutting drill is completed, the positioning and axial deviation that may occur on the slope type / blade-shaped alveolar ridge can be avoided to the greatest extent. Then, under the same guide plate collar, the general guide plate tool box is further used to complete the subsequent cavity expansion and the final implantation of the implant.

[0067] The drill needles of the tool box set of the lateral cutting drill needle guide plate of the utility model are provided with 3 length specifications of short, medium and long (17mm, 21mm and 25mm). Each length specification is respectively provided with 6 diameter sizes (1.4mm, 2.0mm, 2.2mm, 2.4mm, 2.6mm and 2.8mm), and are used in combination with pressing plates of different inner diameters (1.4 / 2.0mm, 2.2 / 2.4mm, 2.6 / 2.8mm). The length of the lateral cutting drill needle of the utility model is consistent with that of the drill needle of the general guide plate tool box. In order to avoid the wear of the pressing plate caused by the lateral cutting drill during the preparation process, the tip of the drill needle is designed to have a 5mm part with lateral cutting ability, and the upper part has no lateral cutting function.

[0068] When preparing the implant cavity on the alveolar ridge with uneven bone surfaces such as slope type and blade shape, it is possible to avoid the deviation of the implant cavity preparation caused by the slipping of the drill needle due to the uneven bone surface. Before preparing the cavity with the drill needle of the general guide plate tool box, this guiding lateral cutting drill can achieve accurate positioning of the implant site, laying a foundation for the accurate subsequent cavity preparation.

[0069] Finally, it should be noted that the above embodiments are only the preferred embodiments of the utility model to illustrate the technical solutions of the utility model, rather than to limit it, and certainly not to limit the patent scope of the utility model. Any meaningless changes or polish made on the main design idea and spirit of the utility model, as long as the technical problems solved are still the same as those of the utility model, shall be included in the protection scope of the utility model; in addition, directly or indirectly applying the technical solutions of the utility model to other related technical fields shall also be included in the patent protection scope of the utility model by the same token.
