Description

 Implant Abutment

The present invention relates to a dental implant abutment.

Implants are originally a substitute that recovers when human tissue is lost, but dental implants refer to implanting artificial teeth.

In order to replace the lost tooth root (root), a tooth root made of titanium and other materials that are not rejected by the human body is planted in the bone where the tooth falls out and the artificial tooth is fixed to restore the function of the tooth.

In general, the implant is a method of implantation by attaching an artificial tooth (prosthetic tooth) on the upper part of the abutment after screwing into the pubis.

Recently, it has been discovered that titanium can act as a root by combining bone with no harmful action in the human body, and the material of artificial teeth used worldwide is mainly titanium metal.

The titanium abutment has a prosthesis forming surface on which the prosthesis is covered and a gingival contact surface in contact with the gingiva when mounted on a fixture embedded in the alveolar bone. In addition to being illuminated by the gingival surface, the dark color of the gingival contact surface is also exposed to the outside through the gingival, so the aesthetics are very poor. Therefore, various abutments have been developed in order to solve the problem of the titanium abutment inferior in the aesthetics.

The conventional titanium abutment has a prosthesis forming surface on which the prosthesis is covered and a gingival contact surface in contact with the gingival when mounted on a fixture embedded in the alveolar bone, and when the prosthesis is exposed to light, In order to solve the problem of very poor esthetics, the dark color of the gingival contact surface is exposed to the outside through the gingival as well as the dark color is reflected out of the prosthesis. However, the abutment as described above has a complicated manufacturing method and is not actually used due to its high unit cost. Thus, abutment is low and provides a ceramic abutment on the contact surface of the gingiva that can be easily manufactured. It is a problem to be solved by the present invention.

In order to solve the above problems, the present invention by fixing the outer lower portion of the abutment made of a ceramic material, to form a gingival contact surface made of a ceramic material close to the ivory color, even if the prosthesis is exposed to light fixation embedded in the alveolar bone When the prosthesis is exposed to light, when the prosthesis is exposed to light, the color of the prosthesis forming surface is not only reflected to the outside of the prosthesis, but also exposed to the outside through the gingiva of the ivory color of the gingival contact surface. Therefore, it is a means for solving the problem to be achieved by the present invention to provide an implant abutment that enhances the aesthetics.

According to the present invention, the ceramic shape forms a gingival contact surface, and even when the prosthesis is exposed to light, the ceramic shape has a gingival contact surface in contact with the gingival when mounted on a fixture embedded in the alveolar bone. As the color is not only reflected out of the prosthesis, but also exposed to the outside through the gingival color of the gingival contact surface, it enhances aesthetics, eases the procedure, and its simple structure reduces the procedure time and pain of the patient and economically. There is an advantage to saving.

In order to achieve the above object, the present invention is inserted into the upper fixing groove (2) formed in the upper portion of the picture and the diameter is narrowed toward the lower side and the abutment lower portion 12 is provided with a male thread on the outside, The abutment body 11 of the inverted triangular pyramid shape located on the upper part of the abutment lower part 12 and a ring-shaped abutment outer lower part of a ceramic material located on the outer lower part of the abutment body 11 ( 20).

Implant abutment of the present invention, all parts are made of titanium or a high-strength alloy, only the abutment outer lower portion 20 located in the lower portion of the abutment body 1 is made of a ceramic material,

The abutment outer lower portion 20 of the ceramic material close to the ivory forms a gingival contact surface, and has a gingival contact surface that contacts the gingival when mounted on a fixture embedded in the alveolar bone even when the prosthesis is exposed to light. When exposed to light, the color of the upper surface of the prosthesis-forming surface is not only reflected to the outside of the prosthesis, but also exposed to the outside through the gingival color of the gingival contact surface, thereby enhancing the aesthetics and creating a natural tooth shape, giving confidence to the implant patient It is an implant abutment to have.
