Description

Technical Field

[0001] This utility model relates to the field of dental instrument technology, and more specifically to a drill bit assembly for exposing implants. Background Technology

[0002] Dental implant surgery consists of a primary surgery and a secondary surgery. The primary surgery involves embedding the implant in the bone, while the secondary surgery involves exposing the implant and installing a healing abutment.

[0003] See attached document Figure 1-2 During secondary surgery, excessive bone growth often results in bone covering the implant, requiring the use of specialized tools to remove the bone above the implant before installing a healing abutment. Currently, long-shank fissure drills are commonly used in clinical practice to remove the bone covering the implant. These drills have a threaded, tapered tip. Due to the limited intraoral operating field, it is difficult for operators to control the drilling depth during the drilling process, leading to inconsistent drilling depths. Furthermore, excessive drilling can easily damage the implant, thus requiring further improvement. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide a drill bit assembly for exposing implants, which allows operators to easily control the overall drilling depth, thereby improving the exposure effect of the implants and facilitating subsequent abutment installation.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A drill bit assembly for exposing implants, comprising:

[0007] An exposed drill bit, comprising a first needle shank and a first needle head, wherein the first needle head is conical, a first protective surface is formed on the surface of the first needle head, and a first frosted surface is formed at the end of the first needle head away from the first needle shank.

[0008] An expanding drill bit, comprising a second needle shank and a second needle head, wherein a second frosted surface is formed on the side of the second needle head, and a second protective surface is formed at the end of the second needle head away from the first needle head.

[0009] As a further improvement of this utility model, both the first needle head and the second needle head are truncated cone-shaped.

[0010] As a further improvement of this utility model, the bottom angles of the first needle head and the second needle head are complementary to each other.

[0011] As a further improvement of this utility model, the bottom angle of the first needle head (3) and the second needle head (8) is at least 60 degrees.

[0012] As a further improvement of this utility model, the minimum diameter of one side of the first needle head and the second needle head is 1.5mm.

[0013] As a further improvement of this utility model, the maximum length of the needle head is 10mm.

[0014] As a further improvement of this utility model, the lengths of the first needle bar and the second needle bar are 20mm-25mm.

[0015] The beneficial effects of this utility model are:

[0016] 1. By using the exposed drill bit and the expanding drill bit in combination, medical staff can easily control the overall drilling depth, thereby improving the exposure effect of the implant and facilitating the subsequent abutment installation.

[0017] 2. By using the combination of exposed drill bit and dilating drill bit, implant damage caused by drilling too deep can be avoided. Attached Figure Description

[0023] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Identical components are indicated by the same reference numerals.

[0024] Reference Figure 3-4 A drill bit assembly for exposing implants includes: an exposure drill bit 1, the exposure drill bit 1 including a first needle shaft 2 and a first needle head 3, the first needle head 3 being tapered, a first protective surface 4 being formed on the surface of the first needle head 3, and a first frosted surface 5 being formed at the end of the first needle head 3 away from the first needle shaft 2.

[0025] It also includes an expansion drill bit 6, which includes a second needle shaft 7 and a second needle head 8. A second frosted surface 9 is formed on the side of the second needle head 8, and a second protective surface 10 is formed at the end of the second needle head 8 away from the first needle head 3.

[0026] Both the first protective surface 4 and the second protective surface 10 are smooth planes.

[0027] In use, the operator first connects the exposure drill bit 1 to the drilling machine, and then uses the exposure drill bit 1 to grind away part of the bone above the implant, thereby exposing the implant. During this operation, the operator can repeat drilling to ensure the drilling depth. When the operator observes the implant, it is considered complete. Then, the expansion drill bit 6 is connected to the drilling machine, and the expansion drill bit 6 is used to grind away the bone on the side of the exposed area of ​​the implant, thereby achieving complete exposure of the implant. Due to the presence of the second protective surface 10, the expansion drill bit 6 can minimize damage to the implant during the operation, which facilitates the subsequent abutment installation.

[0028] Furthermore, in this embodiment, the first needle rod 2 is integrally connected to the first needle head 3, and the second needle rod 7 is integrally connected to the second needle head 8. In another embodiment, the first needle rod 2 and the first needle head 3 are detachably connected. The detachable method is preferably a threaded connection, and the thread screwing direction is consistent with the rotation direction of the first needle head 3. Alternatively, other detachable connection methods in the prior art, including snap-fit ​​and plug-in, can also be used. At the same time, in another embodiment, the second needle rod 7 and the second needle head 8 can also be detachably connected, and the detachable method is consistent with that of the exposed drill bit 1.

[0029] The first needle rod 2, at one end away from the first needle head 3, and the second needle rod 7, at one end away from the second needle head 8, both form connecting ends. These connecting ends form clamping grooves along their length to facilitate connection with the drilling rig.

[0030] Preferably, both the first frosted surface 5 and the second frosted surface 9 are diamond-coated surfaces.

[0031] Preferably, both the first needle head 3 and the second needle head 8 are frustoconical in shape, wherein the smaller end face of the first needle head 3 is located on the side of the first needle head 3 away from the first needle shaft 2, thereby reducing contact with the implant during drilling and minimizing damage to the implant.

[0032] Meanwhile, the larger end face corresponding to the second needle head 8 is located on the side of the second needle head 8 away from the second needle shaft 7, thereby expanding the contact range between the second wear surface and the bone to improve the removal speed.

[0033] Preferably, the bottom corners of the first needle head 3 and the second needle head 8 are complementary.

[0034] Specifically, the bottom angle corresponding to the first needle head 3 is the angle formed by the plane of the end of the first needle head 3 away from the first needle shaft 2 and the measuring line of the first needle head 3. The bottom angle corresponding to the second needle head 8 is the same as that of the first needle head 3, which will not be elaborated on here.

[0035] Preferably, the bottom angle of the first needle head 3 and the second needle head 8 is at least 60 degrees, which ensures that the first needle head 3 and the second needle head 8 are closer to a cylindrical shape, facilitating drilling.

[0036] Preferably, the diameter of one side of the first needle head 3 and the second needle head 8 is at least 1.5mm. This ensures the exposure area, making it easier for operators to observe whether the implant is exposed, and also allows for a larger bottom angle to improve stability during the wear process.

[0037] Preferably, the needle head length is at most 10mm, thereby improving its applicability.

[0038] Preferably, the lengths of the first needle bar portion 2 and the second needle bar portion 7 are 20mm-25mm.

[0039] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
