Description

Dental implant drill

This creation is a drill bit for dental implants, especially a drill bit structure that can fill the inner periphery of the borehole with autogenous bone powder by means of a plurality of obliquely extending chip flutes.

Generally speaking, if a patient has missing teeth without treatment, in addition to the unsightly shortcomings, it will also affect the occlusion, pronunciation, chewing and other functions of the teeth. It will not only affect the life, but also prone to tooth decay, periodontal disease worsening, and even other problems. Teeth are skewed or fall off due to missing teeth. After a long period of time, the appearance is also easy to change due to bone atrophy caused by missing teeth.

In recent years, due to the maturity of dental implant technology, artificial dental implants have become the priority treatment for most patients with missing teeth; artificial dental implants are made of metal implants (such as titanium) that are hard and acceptable to the human body. It is implanted into the alveolar bone, the implant replaces the original tooth root, and then the artificial denture is assembled on the implant to replace the function of the lost tooth.

Of course, in the course of dental implant treatment, the patient may also have insufficient bone in the implant placement position due to various reasons. At this time, psoralen powder has become a necessary step before the dental implant treatment, and the amount of psoralen powder is also relatively small. Affect the cost of bone repair.

Taking the drilling step in the dental implant treatment process, the cutting edge and chip flute of the general dental implant drill are spirally extended from the drill tip along the surface of the drill body, and this drill can only drill the bone during the drilling process. The chips are discharged, and the drilled bone chips (ie, autogenous bone powder) cannot be backfilled into the boreholes of the alveolar bone, resulting in waste of bone chips.

In view of this, the creator of this case actively researched and improved with his many years of relevant design practical experience, and after many physical sample production and testing, he specifically improved the above-mentioned shortcomings of the conventional knowledge, and finally completed the creation.

In order to overcome the above shortcomings, this creation provides a drill for dental implants, which can automatically remove chips during the drilling process, and fill the inner periphery of the drill hole with the bone chips during the retracting process, so as to achieve the recovery of the drilled bone powder. The advantages and effects of utilization.

This creation is a drill for dental implants, which includes: a drill body and a shank; the drill body has a drill point, a tip, a plurality of chip flutes and a plurality of cutting edges, each of the chip flutes is formed by the drill The tip extends obliquely toward the end, and the chip flute is connected to the drill tip and the tip, and each of the cutting edges is formed between the chip flutes; the shank is fixed at the end of the drill body, And has a tool clamping part; wherein, the outer surface of the drill body has a plurality of scale areas.

Please refer to Figures 1 to 3, this creation is a dental implant drill 100, which includes a drill body 10 and a shank 20.

Regarding the drill body 10, it has a drill tip 11, an end 12, a plurality of chip flutes 13 and a plurality of cutting edges 14, each of the chip flutes 13 extends obliquely from the drill tip 11 to the tip 12, and the The chip flutes 13 are connected to the drill tip 11 and the end 12, and the cutting edges 14 are formed between the chip flutes 13 at intervals.

The shank 20 is fixed on the end 12 of the drill body 10 and has a tool holding portion 21; the shank 20 can be used for a power device (such as an electric drill tool or a pneumatic drill, not shown in the figure). (Show) clamping and driving, and then drive the dental implant drill 100 to rotate.

The design of the chip flute 13 in this creation extends in an oblique manner and connects the drill tip 11 and the end 12, which is different from the spiral design of the general implant drill bit. Therefore, the bone debris is not easy to be blocked in each row. In the chip flute 13, a better chip removal effect can be achieved during the drilling process.

In this example, the outer surface of the drill body 10 has a plurality of scale areas 10A of different sizes, and each of the scale areas 10A has different distances; thereby, the user can be exposed to the hole during the drilling process. The outer scale area 10A determines the current drilling depth, and controls the drilling stroke accordingly, which can effectively ensure the accuracy of the drilling. In more detail, due to the small size of the drill bit for dental implants, if text is marked on each scale area 10A, the text is relatively small, and it is difficult for the user to directly distinguish with the naked eye. Therefore, the design of this creation uses The scale areas 10A of various sizes and intervals are designed so that the user can clearly distinguish each scale area 10A to determine the drilling depth and improve the accuracy of drilling.

In this example, the tool holding portion 21 is adjacent to the end 12 of the drill body 10, and opposite sides of the tool holding portion 21 have a pair of cutting planes 211 parallel to each other, which can be used to hold and rotate the tool. (For example: pliers or open-end wrench); when the drill body 10 is stuck during the drilling process or the reversing and retracting process and cannot be rotated, the user can clamp the pliers or set the open-end wrench on the cutting plane 211, and then Rotate the drill body 10 manually.

Please refer to Fig. 4, in use, the implant drill bit 100 of this creation is driven by a power device to rotate clockwise, so that the drill tip 11 and each of the blade portions 14 can drill the alveolar bone 70 and form a drill hole 71 (As shown in Figure 5), and the bone debris (ie, autologous bone powder) generated by cutting during the drilling process is guided to each of the chip grooves 13, and pushed to the end 12 to be discharged (such as The arrow in the figure), to achieve the effect of automatically expelling bone debris during the drilling process.

Please refer to Fig. 5, when the drilling of the borehole 71 is completed, use the power device to drive the implant drill bit 100 of this creation to rotate counterclockwise, and slowly move the power device upward, then the drill body 10 can be withdrawn Drilling hole 71; In addition, during the counterclockwise rotation of the implant drill bit 100, the bone chips (ie, autogenous bone powder 72) in each of the chip grooves 13 on the drill bit body 10 will go to the drill hole 71 The inner periphery is filled to achieve the effect of backfilling bone powder (which can reduce the filling amount of bone powder in the follow-up).

In summary, the advantages and effects of this creation can be summarized as follows:

[1] The drilling depth is accurate. Due to the small size of the drill bit for dental implants, if text is used to mark the scale on the drill bit, the text is relatively small, and it is difficult for the user to directly distinguish with the naked eye; and the design of this creation uses a variety of scale areas with different sizes and different spacings. The 10A design allows the user to determine the current drilling depth according to the scale area 10A exposed outside the bore 71 during the drilling process, and control the drilling stroke accordingly, so it has the advantage of accurate drilling depth.

[2] Bone meal can be backfilled. In the drilling step of dental implant treatment, the cutting edge and chip flutes of general implant drills are spirally extended from the drill tip along the surface of the drill body, and this drill can only discharge the drilled bone debris during the drilling process. , It is not possible to backfill the bone debris into the borehole of the alveolar bone, which causes the waste of bone debris; and this creation uses the inclined design of the plural chip grooves 13, when the implant drill bit rotates counterclockwise, it can make the The bone chips (ie, autogenous bone powder 72) in each of the chip flutes 13 on the drill body 10 are filled to the inner periphery of the drill hole 71, thereby achieving the effect of backfilling the bone powder and reducing the subsequent filling amount of the bone powder. The effect of backfilling bone meal.

The above is only a detailed description of this creation with a preferred embodiment, and any simple modifications and changes made to this embodiment will not depart from the spirit and scope of this creation.

Based on the above detailed description, those who are familiar with this technique can understand that this creation can indeed achieve the aforementioned purpose, and that it has actually complied with the provisions of the Patent Law, and filed a new patent application.
