[0002] The new dental drill for implant guide (hereinafter referred to as the dental drill) is one of the essential products for oral implant surgery. Most of the existing implant pilot drills are traditional twist drills. After drilling with them, medical staff cannot correct the drilling direction, which brings great difficulty to medical staff in operation. When medical staff drill holes on the alveolar bone, due to the small oral space and obstruction during the operation, it is easy to make mistakes in the drilling direction. Utility Model Content

[0003] In view of this, the utility model aims to provide a dental drill for guide plate implantation, which simplifies surgical instruments, is accurate and efficient, reduces the difficulty of operation for medical staff, reduces the pain of patients, and improves surgical efficiency.

[0005] A dental drill for guide plate implantation, comprising a connecting rod, a guide portion and a dental drill portion, wherein the dental drill portion is connected to the connecting rod through the guide portion;

[0006] The connecting rod is used to connect with the mobile phone; the guide part is used to cooperate with the guide plate; the dental drill part is used to complete the dental drill operation;

[0007] The guide part includes a guide column and a limit column connected end to end; the limit column is connected to the connecting rod, and the guide column is connected to the dental drill part;

[0008] A limiting step is formed between the guide column and the limiting column.

[0009] Furthermore, a connecting portion is provided on the top of the connecting rod, and an annular groove is provided on the connecting portion. A right-angle notch is provided on one side of the connecting portion, and the width of the straight notch is equal to the width of the annular groove.

[0010] Furthermore, the ratio of the thickness of the guide pillar to the thickness of the limiting pillar is in the range of 3:1-4:1.

[0011] Furthermore, the ratio of the diameter of the guide column to the diameter of the limiting column is 2:3.

[0012] Furthermore, the ratio of the length of the connecting rod to the length of the guide portion is in the range of 2.5:1-3:1.

[0013] Furthermore, the dental drill part is provided with four chip removal grooves, and the four chip removal grooves enable the dental drill part to form four cutting parts;

[0014] The chip groove and the cutting part are both spiral, and the cutting surface of the cutting part is serrated.

[0015] Furthermore, the structures of the cutting parts are the same, and the cross sections of the four cutting parts are within a circle.

[0016] Furthermore, each sawtooth of the cutting surface is triangular in shape, and the size ratio is 26:87:92.

[0017] Furthermore, the surfaces of the guide part and the dental drill part are both provided with a DLC coating.

[0018] Compared with the prior art, the dental drill for guide plate implantation described in the utility model has the following advantages:

[0019] (1) The utility model is a dental drill for guide plate implantation, which is a guide plate pilot drill with a side cutting function. After drilling, the side cutting can be performed to correct the drilling direction, thereby simplifying surgical instruments, increasing precision and efficiency, reducing the difficulty of operation for medical staff, reducing the pain of patients, and improving surgical efficiency.

[0020] (2) The utility model provides a dental drill for guide plate implantation, wherein the dental drill for guide plate implantation has a guide post that cooperates with the guide plate to improve accuracy and avoid errors in the drilling direction.

[0021] (3) The utility model provides a dental drill for guide plate implantation. The structure design can reduce the friction between the dental drill and the alveolar bone during the drilling process, thereby avoiding heat generation during the drilling process.

[0022] (4) The utility model is a dental drill for guide plate implantation, wherein the guide part and the dental drill part are plated, thereby increasing the wear resistance of the drill, improving the sharpness and wear resistance of the dental drill, and making the dental drill durable.

[0023] (5) Compared with the traditional pilot drill, the utility model is a dental drill for guide plate implantation. The chip removal is smoother and there will be no chip jamming or difficulty, which would cause the operation to be interrupted. The traditional twist drill structure can only continue the operation after the bone chips in the chip groove are cleaned.

[0024] (6) The utility model provides a dental drill for guide plate implantation, which is provided with a limit step to prevent the drill from being drilled too deep or damaging other tissues. BRIEF DESCRIPTION OF THE DRAWINGS
