Description

Healing abutment for dog teeth {HEALING ABUTMENT FOR CANINE}

The present invention relates to a canine healing abutment, and more particularly, to a canine healing abutment reflecting the tooth shape of individual dogs.

Generally, an implant refers to a replacement to restore the original tissue when it is lost, whereas a dental implants an artificial tooth. To replace the lost root (root), a root made of titanium or the like which does not have a rejection reaction to the human body is planted in the alveolar bone that has passed through the tooth, and then the tooth is restored by fixing the artificial tooth.

In general prostheses or dentures, the surrounding teeth and bones are damaged over time, but the implants do not injure the surrounding dental tissue, and they have the same function and shape as the natural teeth, but do not have cavities. Therefore, they can be used semi-permanently.

Implants also improve the function of dentures in patients with single missing teeth restoration, as well as partial and total toothless teeth, and improve the aesthetic aspects of dental prosthesis restoration. Furthermore, it helps to stabilize the dentition as well as to disperse the excessive stress applied to the surrounding supporting bone tissue.

The dental implants are divided into a gingival bone, namely, a surgical procedure for implanting an implant on an alveolar bone, and a prosthetic procedure for attaching an artificial tooth by connecting an abutment to an implanted implant.

There are a variety of implants for these implants, and one of them is described as follows. The implant procedure described below is a fixture level impression method of completing impression models by connecting impression copings in the oral cavity when the impression is taken in the prosthetic process.

First, grooves corresponding to fixture dimensions are formed through drilling and tapping processes in the alveolar bone, and a mount is mounted on the fixture. Then, the fixture and the mount are embedded in the alveolar bone using the surgical hand piece and then the mount is removed from the fixture, thereby embedding the fixture in the alveolar bone.

The first operation is completed by fastening the cover screw to the upper part of the fixture to seal the fixture.

The lid screw blocks bacteria and foreign objects present in the oral cavity from entering the fixture while waiting for the fusion of the fixture. The duration of ossification is somewhat different depending on the patient's bone quality and implantation position, but usually takes 3 to 6 months.

Subsequently, open the gum to expose the cover screw through the second operation, check the degree of bone fusion of the fixture, and remove the cover screw. Then heal healing abutment (Healing Abutment) to the top of the fixture for aesthetic gum formation, and wait for two to three weeks. In recent years, in order to improve the complexity of the second procedure, a first procedure of directly fastening the healing abutment and eliminating the process of fastening and removing the cover screw may be used.

Next, after confirming aesthetic gum formation, the healing abutment is removed, and an impression coping is fastened to the upper part of the fixture to produce a prosthesis. The impression material is then used to create a preliminary impression in the mouth and remove impression copings.

After that, a tooth model is made and artificial teeth, ie, artificial dental crowns, are fastened with abutments on the upper part of the fixture, and the artificial teeth are fixed by fixing a prosthesis, that is, artificial dental crowns on the abutments.

As such, healing abutments are generally used for aesthetic gum formation during implantation.

Since the implant procedure is widely practiced and the technique is widely known and developed in recent years, the result of the implant procedure may be required among the patients as a result of the aesthetic after the implant procedure. Therefore, the esthetic result is more important after the implant procedure have.

However, conventional healing abutments are made to have shapes that are irrelevant to tooth formation. For example, the cross-sectional shape is formed to have a circular shape.

That is, the conventional healing abutment is formed to have a shape suitable for use with a particular abutment.

Thus, the conventional healing abutment is not suitable for fabricating and using abutments tailored to individual teeth.

In order to solve this problem, conventionally, to produce a separate abutment in the dental laboratory so as to be located in the gum portion of each tooth artificially produced a gum shape.

For example, in order to make a gum shape in order to use a custom abutment as described above, a resin is added to a specific shape on a titanium base and then a curing and polishing process is used.

However, such a method not only wastes time and money, but also provides a cause of the procedure failure due to the problem of bacterial infection.

In particular, the canine is located behind the maxillary and in front of the mandible. Thus, canines have an important aesthetic significance.

Accordingly, in recent years, the development of a healing abutment reflecting the oral environment in individual dogs of patients is required to solve the above problems.

In the prior art related to the present invention, there is a Republic of Korea Utility Model No. 20-0428106 (October 09, 2006 Announcement Date), the prior art discloses a description of the healing rent.
