Description

Restorable one-piece implants

technical field

The utility model relates to an innovative structural design of a one-piece implant, especially a repairable one-piece implant.

Background technique

The traditional dental implant surgery is to embed an implant in the patient's gum, then assemble an abutment with screws on the implant, and assemble an abutment on the abutment after the wound is healed. Crowns to complete dental implants.

There is a design of a one piece implant body (one piece implant) at present, which integrates the support frame and the dental implant body, so as to facilitate the implantation operation of the dental implant body and the support frame at one time.

In addition, the current crown post and crown core (Post and core) production technology has been applied in dental surgery. Generally, when the tooth structure is damaged, decayed, or fractured, there is not enough tooth structure to properly assemble the crown. The crown pillar and crown core manufacturing technology can restore the tooth structure and facilitate the crown assembly. However, this post and core fabrication technology has not yet been applied to the root structure of dental implants.

However, after a single-piece dental implant is installed with a crown, under long-term use or improper use, sometimes the bracket will break, making the crown detached from the gum and can no longer be used. At this time, the root remaining in the gum must be pulled out and reassembled; in such a situation, it is more likely to cause the failure of the implant. This problem needs to be improved.

Contents of the invention

For this reason, the purpose of the present utility model is to provide a repairable single-piece dental implant body, which can conveniently perform crown post and crown core manufacturing technology to repair the support frame when the support frame breaks, thereby improving the efficiency of dental implantation.

To achieve the above purpose, the utility model discloses a repairable single-piece dental implant, comprising:

a root portion with a coarse thread portion below which can be tapped into the gum, and a fine thread portion formed above the coarse thread portion; and

a stand, which is integrally connected above the fine thread part of the root, and a crown is installed on the support stand;

It is characterized in that: vertically downward from the top surface of the support frame, when the support frame breaks, use its space to carry out the crown column and coronary heart manufacturing technology, and embed a post nail inside to make the broken support The through hole for bench restoration, the bottom of the through hole extends to be close to the bottom end of the rooted part.

Wherein, there are a plurality of helical grooves on the outside of the thick threaded part of the root, and the edges of the helical grooves form a cutting edge that cuts the bone tissue in the gum and pushes the cut bone tissue into the gum when it is implanted into the gum. .

Through the above-mentioned structure, the utility model can repair the broken bracket by using the through hole opened inside the single-piece dental implant, and using the manufacturing technology of crown pillar and crown core, which is much better than the conventional single-piece dental implant. The effect is better.

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 repairable single-piece dental implant body 10, which mainly has a root part 11, and a thick hole that can penetrate into the gum 20 is provided under the root part 11. A threaded portion 111, and a thin threaded portion 112 is formed above the coarse threaded portion 111. The coarse threaded portion 111 has a plurality of helical grooves 113, and edges of the helical grooves 113 form a cutting edge 113a.

The stand 12 is integrally connected above the fine thread portion 112 of the root portion 11 , and has multiple ribs 121 on its surface, and can be used to install a crown 30 thereon, as shown in FIG. 4 .

Referring to FIG. 2A , the utility model mainly opens a through hole 13 vertically downward from the top surface of the stand 12 , and the bottom of the through hole 13 extends to the bottom end close to the root portion 11 .

When in use, as shown in Figure 3, the root portion 11 can be rotated into the gum 20 at high speed, and the bone tissue in the gum 20 can be cut due to the cutting edge 113a formed on the edge of the helical groove 113, and the bone tissue cut Push it into the gum 20, as shown by the arrow in the figure, if combined with the sinus membrane lifting operation, the cut bone tissue can be pushed into the pushed up sinus membrane space. With the design of the helical groove 113 , supplementary bone meal can be inserted at the same time during implantation, and the helical groove 113 is pushed to fill the periphery of the root portion 11 to form a stable structure.

After the implantation wound is healed, as shown in FIG. 4 , a dental crown 30 is installed outside the stand 12 to complete the implantation operation.

Referring to FIG. 5 , under long-term use or improper use of the dental crown 30 , sometimes the abutment frame 11 may be broken, so that the dental crown 30 is detached from the gum 20 . At this time, as shown in Figure 6, the post and core manufacturing technology can be carried out in the space formed by the through hole 13, and a post nail 14 is embedded in the through hole 13 to fix the broken abutment Rack 12 repaired. As shown in FIG. 7 , the dental crown 30 is installed back on the stand 12 to complete the restoration.

The utility model utilizes the through-hole 13 opened inside the single-piece dental implant body 10, and utilizes the post and core (Post and core) production technology to repair the broken bracket 12, which is much better than the conventional single-piece dental implant. It is better to use a piece of dental implant.

In summary, the utility model fully complies with the requirements of novelty and progressiveness of the patent, and an application is filed according to the law.
