Description

Technical Field

[0001] The invention relates to the field of measuring instruments specially suitable for dentistry, in particular to a depth measuring ruler for dental implantation. Background Art

[0002] The depth gauge for dental implants is a dental implant surgery tool used to measure the depth of the implant cavity, the gap in the oral cavity and other parameters during dental implant surgery. After measuring the implant cavity with the depth gauge for dental implants, the implant of the corresponding length and diameter is implanted into the implant cavity, and then the abutment that matches the implant is installed on the implant, and finally the abutment is locked to the implant with the matching central screw. Before implanting the implant into the implant cavity, it is necessary to check whether the implant, abutment and central screw match. Since the sizes of the implant, abutment and central screw are all standard values, generally measuring the outer diameters of the three can determine whether the three match. However, it takes a long time to measure the outer diameters of the implant, abutment and central screw, which reduces the efficiency of the operation. Summary of the invention

[0003] The purpose of the present invention is to provide a depth measuring ruler for dental implants to solve one or more technical problems existing in the prior art and at least provide a beneficial choice or create conditions.

[0004] The technical solutions adopted to solve the above technical problems are:

[0005] A depth measuring ruler for dental implantation, comprising:

[0006] main body;

[0007] a probe disposed at a distal end of the body;

[0008] A plurality of screw holes with different apertures, all of the screw holes being distributed at intervals on the main body;

[0009] A plurality of base interfaces with different apertures, all of which are spaced and distributed on the main body;

[0010] A plurality of implant interfaces with different apertures, all of which are spaced and distributed on the main body.

[0011] The beneficial effects of the present invention are as follows: the probe at the end of the main body is used to measure the depth of the implant cavity, and multiple screw holes with different apertures on the main body are adapted to central screws with different outer diameters, thereby distinguishing different types of central screws; multiple abutment interfaces with different apertures on the main body are adapted to abutments with different outer diameters, thereby distinguishing different types of abutments with different face angle relationships; multiple implant interfaces with different apertures on the main body are adapted to implants with different outer diameters, thereby distinguishing different types of implants; since the outer diameter of the implant, the outer diameter and face angle relationship of the abutment, and the outer diameter of the central screw are all standard values, and there is a relatively definite assembly relationship between the matching implants, abutments, and central screws, after using a dental implant depth measuring ruler to distinguish the types of implants, abutments, and central screws, the three can be matched and used as soon as possible, thereby improving surgical efficiency.

[0012] As a further improvement of the above technical solution, the plurality of base interfaces are arranged at the top ends of the plurality of screw holes in a one-to-one correspondence.

[0013] The plurality of base interfaces are arranged one by one at the top ends of the plurality of screw holes, thereby reducing the space of the main body occupied by the base interfaces.

[0014] As a further improvement of the above technical solution, a slot is provided on the side wall of each screw hole, the slot passes through the main body, and the slot connects the screw hole with the outside.

[0015] As a further improvement of the above technical solution, a slot is provided on the side wall of each screw hole, the slot passes through the main body, and the slot connects the screw hole with the outside.

[0016] The slot on the side wall of each screw hole passes through the main body. When the central screw is inserted into the screw hole to judge the outer diameter of the central screw, the matching condition between the central screw and the screw hole can be observed through the slot, which makes it easier to judge the outer diameter of the central screw; the slot is also more convenient for cleaning and prevents bacterial growth.

[0017] As a further improvement of the above technical solution, the base interface is a regular polygonal hole.

[0018] The base interface is a regular polygonal hole, which matches the bottom polygonal anti-rotation structure of the base.

[0019] As a further improvement of the above technical solution, all the implant interfaces are located at the edge of the main body, and each of the implant interfaces is a semicircular hole.

[0020] Each implant interface is a semicircular hole located at the edge of the main body. The implant is placed into the implant interface from the edge of the main body, and the fit between the implant and the implant interface is observed to determine the outer diameter of the implant. The operation is convenient, and the assembly and separation of the implant and the implant interface are easier.

[0021] As a further improvement of the above technical solution, the depth measuring ruler for dental implants also includes a base penetration height measurement groove, which extends in a horizontal direction, and a base mounting cavity is provided at one end of the base penetration height measurement groove, and a penetration height scale is provided on the bottom wall of the base penetration height measurement groove.

[0022] The bottom of the abutment is embedded in the abutment mounting cavity, and the abutment extends horizontally in the abutment gingival height measuring groove, and the top of the abutment is located in the abutment gingival height measuring groove. The length of the abutment is determined according to the reading of the gingival height scale.

[0023] As a further improvement of the above technical solution, the bottom surface of the main body is a plane, and all the screw holes, all the abutment interfaces, and all the implant interfaces are located on the top of the main body.

[0024] The bottom surface of the main body is a plane, and the main body can be placed horizontally on the plane. The screw hole, the base interface, and the implant interface are located on the top of the main body, which is convenient for judging the outer diameter of the central screw, the base, and the implant, and then distinguishing the matching of the central screw, the base, and the implant.

[0025] As a further improvement of the above technical solution, with the position of the probe relative to the main body as the relative front direction, all the screw holes are arranged in sequence along the front-to-back direction, and all the screw holes are arranged backward in sequence from large to small according to the hole diameter.

[0026] All screw holes are arranged backwards in order from large to small according to the hole diameter. When testing the central screw, multiple screw holes of the central screw can be tested in order from front to back to facilitate the determination of the outer diameter of the central screw.

The diameter of the two screw holes 110 located in the front is 1.0 mm, and the diameter of the two screw holes 110 located in the back is 0.9 mm. Each screw hole 110 runs through the main body 100 from top to bottom, and all screw holes 110 are located on the left edge or the right edge of the main body 100. The side wall of each screw hole 110 is provided with a slot 111, which runs through the main body 100 in the left-right direction, and the slot 111 connects the screw hole 110 with the outside world.
