Description

bone level implant

technical field

The utility model relates to a bone level implant used in dentistry.

Background technique

Implants are also known as dental implants, also known as artificial tooth roots. It is surgically implanted into the upper and lower jaws of the edentulous part of the human body. After the surgical wound heals, a device for repairing dentures is installed on its upper part. Generally, there are bone level implants and soft tissue level implants. Implants generally include an implant part for implanting in human tissue, an abutment part for installing dentures, and a connecting part for connecting the implant part and the abutment part. In oral implant surgery, the growth of the patient's teeth The directions are different. Therefore, the abutment often needs to be designed to be inclined in different directions. At present, the connection structure of the bone-level implant adopts the cross-lock shape connection design, which has less angle adjustment, weak implant strength and poor stability.

Contents of the invention

In order to overcome the above-mentioned shortcomings of the prior art, the utility model provides a bone level implant that can increase the adjustment angle and has better stability.

The technical scheme that the utility model solves its technical problem is:

A bone-level implant, comprising an implant part implanted into a human body, an abutment for fixing artificial dentures, and a connection part connecting the implant part and the abutment, and the connection part includes a The connection hole, the connection hole includes a screw hole arranged in the lower section of the connection hole and a taper hole arranged in the upper section of the connection hole, the lower end of the taper hole is set as a regular octagonal hole, and the upper end of the taper hole is set as a conical hole. The regular octagonal hole and the conical hole are connected in an arc shape, and the lower part of the abutment part is provided with a regular octagonal part matching the regular octagonal hole and an inclined part matching the conical hole.

Preferably, the implant part is set in a straight rod shape, and the outer surface of the implant part is provided with threads, the depth of the threads at the lower end of the implant part is the same, and the depth of the threads at the upper end of the implant part gradually becomes shallower.

Preferably, the lower end of the implant part is set as an arc surface, and the taper of the conical hole is 1:7.

Preferably, the upper end of the inclined portion of the base is connected to the second inclined portion, and the outer surface of the second inclined portion is set as an arc surface.

The upper section of the connection hole used to connect the implant part and the abutment is set as a taper hole, and the lower section of the taper hole is set as a regular octagonal hole, and the upper end of the taper hole is set as a conical hole, then the abutment is provided with a regular octagonal part and Inclined part. The implant part is set in a straight rod shape, but the thread depths on the surface are different, and the thread depth at the upper end of the implant part gradually becomes shallower, that is, the surface formed by the bottom of the thread at the upper end of the implant part is an arc surface. The upper end of the inclined portion of the base is also provided with a second inclined portion.

The beneficial effect of the utility model is that: through the octagonal and taper design of the connecting part, the adjustment angle is increased to facilitate the installation of dentures, the octagonal design itself also increases the strength of the implant itself, and the taper design improves the stability after connection.

Detailed ways

The utility model is described in further detail below in conjunction with accompanying drawing and specific embodiment.

As shown in Figures 1 and 2, a bone level implant includes an implant part 1 implanted into the human body, an abutment 8 for fixing artificial teeth, and a connecting part connecting the implant part and the abutment, and the connecting part includes The connection hole arranged on the upper part of the implant part, the connection hole includes a screw hole 3 arranged in the lower part of the connection hole and a taper hole arranged in the upper part of the connection hole, the lower end of the taper hole is set as a regular octagonal hole 4, and the upper end of the taper hole is set as a conical The holes 9, the regular octagonal holes 4 and the conical holes 9 are connected in an arc shape, and the lower part of the abutment 8 is provided with a regular octagonal part 5 matching the regular octagonal holes 4, and an inclined part 6 matching with the conical holes. The upper end of the inclined part of the base is connected to the second inclined part 7, and the outer surface of the second inclined part 7 is set as an arc surface. The implant part 1 is set in a straight rod shape, and the outer surface of the implant part is provided with threads 2, and the depth of the threads at the lower end of the implant part is the same, and the depth of the threads at the upper end of the implant part gradually becomes shallower. The lower end of the implant part is set as an arc surface, and the taper of the conical hole 9 is 1:7.

The upper section of the connection hole used to connect the implant part and the abutment is set as a taper hole, and the lower section of the taper hole is set as a regular octagonal hole 4, and the upper end of the taper hole is set as a conical hole 9, and the corresponding abutment 5 is provided with a positive Octagonal part 5 and inclined part 6. The implant part is set in a straight rod shape, but the thread depths on the surface are different, and the thread depth at the upper end of the implant part gradually becomes shallower, that is, the surface formed by the bottom of the thread at the upper end of the implant part is an arc surface. The upper end of the inclined portion of the base is also provided with a second inclined portion.

Through the octagonal and taper design of the connection part, the adjustment angle is increased, which facilitates the installation of dentures. The octagonal design itself also increases the strength of the implant itself, and the taper design improves the stability after connection.
