Description

Dental implant assembly {DENTAL IMPLANT ASSEMBLY}

The present invention relates to a dental implant assembly, and more particularly, to a dental implant assembly used to restore a patient's missing teeth.

An implant refers to a replacement that restores lost human tissue. Generally, in dentistry, a fixture is implanted and adhered to the alveolar bone where the natural tooth root has come out to replace the tooth root of a lost tooth, and then an artificial tooth is fixed to restore the tooth's original state. It refers to a replacement that can restore function.

The general dental implant assembly described above may include a fixture, an abutment, and an artificial tooth.

The fixture is embedded in the alveolar bone and serves to fix the entire implant assembly, and such fixtures are generally made of titanium, etc., which has excellent biocompatibility for fusion with human bone tissue.

The abutment is coupled to the fixture and functions to fix and support the artificial tooth.

The artificial tooth is manufactured in the form of a tooth through fixation such as impression taking, working model production, wax mold production, burial and recall processes, etc.

As an example of the surgical method of the dental implant assembly as described above, a groove corresponding to the dimensions of the fixture is formed in the alveolar bone through a drilling and tapping process, and a mount is fastened to the upper part of the fixture. Afterwards, the first surgery is completed by implanting the fixture and mount into the alveolar bone using a surgical hand piece, removing the mount from the fixture, fastening a cover screw to the top of the fixture, and suturing the gums.

Here, the cover screw blocks bacteria and foreign substances present in the oral cavity from entering the interior of the fixture while waiting for osseointegration of the fixture. Meanwhile, the osseointegration period varies somewhat depending on the patient's bone quality and implant location, but generally takes 3 to 6 months.

Next, through a second surgery, the gums are opened to expose the cover screw, the degree of osseointegration of the fixture is checked, and the cover screw is removed. Then, to form aesthetic gums, a healing abutment is fastened to the top of the fixture and waits for about 2 to 3 weeks.

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 fabricate a prosthesis. Next, a preliminary impression is taken in the oral cavity using impression material, and the impression coping is removed.

Afterwards, a tooth model is made, the artificial tooth is processed, an abutment is fastened to the upper part of the fixture, and the artificial tooth, which is a prosthesis, is fixed to the abutment to complete the implant assembly procedure.

However, when implanting the fixture into the alveolar bone, if the drilling angle is wrong and the fixture is unintentionally tilted, or if the fixture must be implanted to be intentionally tilted depending on the condition of the patient's alveolar bone and teeth, an artificial tooth, which is a prosthesis, must be placed in the fixture. There may be cases where it has to be installed at an angle.

In such cases, the prosthesis is installed using an abutment with a predetermined tilt angle to compensate for the tilt angle of the fixture.

However, in the case of a conventional abutment with a general inclination angle, a screw thread is formed at the bottom of the outer peripheral surface of the abutment, and the abutment is manufactured in a structure that rotates and couples it to the fixture, so that the inclination direction of the abutment with the inclination angle is formed. There is a problem that it is difficult to adjust and combine it with the fixture.
