Description

Technical Field

[0001] The utility model relates to the technical field of oral medical equipment, in particular to a medical drill bit structure for oral implant cavity preparation. Background Art

[0002] The oral implant drill is a tool that must be used for dental implants. The drill bits are divided into fixed-point drills, fixed-depth drills, and fixed-shaped drills. There are many types of implant systems on the market. There is no unified drill for initial implant cavity preparation, and there is no guide device to allow the drill preparation process to strictly prepare the cavity around the center point of the missing tooth. Only surgical preparation plans are considered, and no future repair plans are considered. If the implant physician fails to accurately control the position of the center point, it is easy to cause the drill to deviate from the center point, resulting in the deflection of the later restoration to produce a cantilever beam, causing food impaction and implant edge bone absorption. Therefore, based on the above problems, it is necessary to design a drill structure suitable for all implant systems to ensure that the implant physician can maintain the same feel when using different implant systems for initial implant cavity preparation. At the same time, during the cavity preparation process, the cavity preparation is carried out tightly around the center of the implant, effectively avoiding the occurrence of drill offset problems. Utility Model Content

[0003] The utility model aims to provide a medical drill bit structure for preparing oral implant cavities.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A medical drill bit structure for preparing an oral implant cavity comprises a connecting portion, a guiding portion and a drill portion which are arranged in sequence from top to bottom. The top of the connecting portion is mounted on an implanter, and the bottom is mounted on the guiding portion. The guiding portion is a conical structure which is larger at the top and smaller at the bottom. When in use, the guiding portion is placed in a toothless gap for positioning. The guiding portion is provided with at least one flushing channel for flushing with saline. The drill portion is arranged at the bottom end of the guiding portion for preparing a hole in the jawbone.

[0006] Furthermore, the drill head is one of a positioning drill, a depth-setting drill or a shaping drill.

[0007] Furthermore, the drill head is a positioning drill, which is a rod body and has a spherical positioning head at the end for positioning. The length of the rod body is 5 mm and the diameter is 2 mm. The diameter of the spherical positioning head is one of 0.5, 1, 1.5 and 2 mm.

[0008] Furthermore, the drill head is a fixed depth drill with a length of 10 mm and a diameter of one of 1.5, 2, 2.5 and 3 mm. Its outer wall is provided with a serrated structure for drilling, and a laser mark is provided on its outer wall for determining the drilling depth of the drill head.

[0009] Furthermore, the drill head is a shaped drill, the length of which is 10 mm, the diameter of which is one of 2.5, 3, 3.5 and 4 mm, and the outer wall of which is provided with a twist drill structure.

[0010] Furthermore, the structure of the flushing channel communicating with each other from top to bottom is used when the drill head is performing cavity preparation on the jawbone, and is connected to a water pump, which delivers physiological saline solution inward for cleaning and cooling.

[0011] After adopting the above technical solution, the utility model has the following advantages compared with the background technology:

[0012] The utility model provides a guide part on the drill bit structure, which is a tapered structure with a larger upper part and a smaller lower part. When in use, it is placed in the middle of the tooth missing gap for positioning, so that no matter whether it is a fixed point, fixed depth or fixed shape operation, it can be accurately operated on the positioning point, thereby ensuring that the implant physician can maintain the same feel when using different implant systems for initial implant cavity preparation drill bits. At the same time, during the cavity preparation process, the cavity preparation is carried out closely around the center of the implant, effectively avoiding the occurrence of the drill bit deviation problem.

[0018] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0019] It should be noted that in the present invention, the terms "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element of the present invention must have a specific orientation, and therefore cannot be understood as a limitation on the present invention.
