Description

One Piece Angled Implants

technical field

The utility model relates to a single-piece angle implant body, which is used for implanting in an inclined anterior gum bed, so as to install a crown.

Background technique

Dental implant surgery generally involves first embedding an implant into the gum, and then installing a separate and exposed abutment above the implant to facilitate the installation of an abutment on the abutment. Crowns to complete dental implants.

In order to improve the time of dental implant surgery, there is an integral molding of the frame and the implant to form a one piece implant, such as in the US Patent No. 5,961,328 "Dental Implant". , provides such a technique.

However, because the gums of implant patients sometimes tilt, especially in the position of the front gums, when implanting the gums with the known single-piece dental implant structure, it is easy to cause the upper bracket to be not perpendicular to the gum surface, making the The installed crown is prone to tilt, making the implant fail. This problem needs to be improved.

Contents of the invention

For this reason, the purpose of the present utility model is to provide a single-piece angled dental implant, which can be implanted in inclined anterior gums.

In order to achieve the above purpose, the utility model discloses a single-piece angled dental implant, which is implanted in the inclined anterior gum; it is characterized in that it includes:

An implant body has a first central axis, the upper section of the first central axis forms a cylindrical fine thread part, and the lower part forms a tapered coarse thread part;

a stand, which is integrally connected to the top of the cylindrical fine thread part of the implant body to assemble a dental crown; the support stand has a second central axis, and the second central axis is inclined at an angle to the first central axis; and

A keying concave hole extends downward from the outer surface of the support frame along the direction of the first central axis, and forms a plurality of holes near the bottom to be keyed by a rotary tool with a matching joint so that the implant body Anchored to the bonding surface within the sloped anterior gum.

Wherein, the inclination angle range between the first central axis of the implant body and the second central axis of the bracket is 5-25°.

Wherein, at least one helical groove is opened on the surface of the tapered coarse thread portion of the implant body.

Through the above-mentioned structure, the single-piece angled dental implant body provided by the utility model has a special structure, so that it can be conveniently and quickly implanted into the inclined anterior gum during surgery, so that the success rate of the dental implant surgery is greatly improved.

Hereinafter, the structural features and usage effects of the present utility model will be described in detail according to the embodiments shown in the drawings.

Detailed ways

Please refer to Fig. 1 to Fig. 3, the utility model provides a single-piece angle implant body 1, which is used to implant in the inclined anterior gum 2, as shown in Fig. 5, and a crown is installed on the anterior gum 2 3. The utility model is mainly composed of an implant body 11 (implant body), a stand 12 (abutment) and a bonding concave hole 13.

The implant body 11 has a first central axis L1, the upper section of the first central axis L1 forms a cylindrical fine thread part 111, and the lower section forms a conical coarse thread part 112, and on the surface of the conical coarse thread part 112, there is a Up to a plurality of helical grooves 113 . When the implant body 11 is rotated, the cutting effect produced by the tapered coarse thread portion 112 and the columnar fine thread portion 111 can be stably implanted in the inclined anterior gum 2 .

The stand frame 12 is integrally connected to the top of the cylindrical fine thread portion 111 of the implant body 11 to assemble a dental crown 3 (see FIG. 5); the stand frame 12 has a second central axis L2, and the second central axis L2 is inclined at an angle to the first central axis L1, and the angle of inclination ranges from 5° to 25°.

The bonding concave hole 13, referring to Fig. 2, extends downward from the outer surface of the stand 12 along the direction of the first central axis L1, and forms a plurality of bonding surfaces 131 near the bottom, with three keys shown in Fig. 3 131, and these bonding surfaces 131 are bonded by a rotating tool 14 with a matching joint 141 as shown in Figure 4, so that the implant body 11 is rotated and anchored (anchor) on the inclined anterior gum 2 within.

In actual operation, firstly insert the joint 141 of the rotary tool 14 into the bonding concave hole 13, so that the joint 141 is bonded to the bonding surface 131; then, align the bottom end of the implant body 11 with the surface of the anterior gum 2 , and given rotation, so that the implant body 11 is embedded in the anterior gum 2 , and the abutment frame 12 is exposed on the surface of the anterior gum 2 , and the second central axis L2 is perpendicular to the surface of the anterior gum 2 . After the wound is healed, the crown 3 can be installed and fixed on the stand 12 .

Because the single-piece angled implant 1 provided by the utility model has a special structure, it can be conveniently and quickly implanted into the inclined anterior gum 2 during surgery, and the success rate of the implant surgery is greatly improved.
