Description

[0001] DENTAL IMPLANT AND ABUTMENT [0002]

The present invention relates to dental implants and abutments.

Implant refers to a structure that restores when a tissue is lost, but it refers to an artificial structure that allows an artificial tooth to be implanted in a dentist. In other words, a dental implant is a structure that restores the function of a tooth by replacing a missing tooth with an artificial root made of a material that does not cause a reaction to the body, after it is planted in an alveolar bone that has passed through the tooth, and then an artificial tooth is fixed.

Dental implants consist largely of artificial roots (fixtures), abutments, and artificial crowns. The artificial root is a part of the tooth that serves as the root of the tooth. The tooth is fixed to the alveolar bone from which the tooth has escaped. The abutment is a part that serves to connect the artificial crown to the artificial root and is fastened on the artificial root. It corresponds to the head of a tooth in a natural tooth as a prosthesis.

Organic matter and germs such as food residues accumulate between the implants and the gums, and inflammation of the gums around the implants occurs. As a result, the alveolar bone tissue surrounding the implants melts and the implants must be extracted.

Conventionally, methods such as scaling, antibiotic administration, oral cleaning agent, and brushing have been used to remove bacterial warts, plaques, jig and calculus which may cause such inflammatory reaction.

However, scaling and brushing methods do not remove contaminants below the gums, and methods using antibiotics and mouthwashes are neutralized by the biofilms they make to survive, making bacteria, teeth, teeth, There is a limit to the removal.
Recently, there has been studied a technique for preventing bacterial infection around the implant even after implantation of the implant into the gum by including an antimicrobial coating layer on the surface of the dental implant (for example, Patent Document 1). In the dental implant disclosed in Patent Document 1, the antimicrobial coating layer is surface-treated on the abutment surface to induce photocatalysis by visible light to prevent inflammation. However, these dental implants can not control the photocatalytic reaction automatically, which limits the prevention of bacterial infection.
