Description

A jig for mounting an inclined abutment {fitting zig for angled abutment for denture}

The present invention relates to a jig for attaching an inclined abutment, and more particularly, to a jig for installing an inclined abutment that accurately guides the fastening of an inclined abutment and a fixture, but improves the convenience and safety of implant placement. .

In general, dentures or prostheses refer to artificial periodontal tissue in the oral cavity that replaces missing teeth to artificially restore appearance and function.

In detail, when natural teeth are left in a lost state, distortion of the teeth occurs in adjacent teeth and opposing teeth of the missing teeth, resulting in deformation of the facial shape, and deterioration of the masticatory function, thereby increasing inconvenience in daily life. Moreover, when the loss of natural teeth continues for a long time, there is a problem in that the alveolar bone surrounding the missing teeth is absorbed into the body, making it difficult to install artificial periodontal tissue.

At this time, the dentures or prostheses can be installed inside the oral cavity to restore the masticatory function and prevent periodontal tissue deformation, and can be divided into partial/complete dentures and partial/complete prostheses according to the number of missing teeth.

On the other hand, the denture is installed by applying a dental adhesive to the mold groove on the inner surface side and being adhered to the surface of the gum, and the prosthesis may be installed through a fixture placed in the alveolar bone. At this time, as the dentures are supported on the outer surface of the gums, deformation of the gums or a feeling of a large amount of foreign body is caused.

In detail, a plurality of fixtures capable of supporting the prosthesis are placed on the gum at predetermined intervals along the dental arch, and an abutment is coupled to the upper end thereof. In addition, the prosthesis has a fastening portion fixed to the upper end of the abutment at a position corresponding to each upper end of the abutment is formed. In this case, the fastening portion may be provided as a support cylinder that is vertically through-arranged to correspond to each position of the abutment, or may be formed as a fastening groove recessed in the vertical direction to correspond to the upper end profile of the abutment. That is, as the upper end of the abutment is substantially interpolated into the fastening portion and fixed by a fixing means, the prosthesis may be installed in the oral cavity.

On the other hand, in the portion corresponding to the anterior teeth of the gum, the fixture is substantially placed in a vertical direction corresponding to the forming direction of the fastening portion. On the other hand, in the part corresponding to the posterior side of the gum, especially in the mandible, when the fixture is placed in the vertical direction as the lower alveolar nerve passes on both sides of the jaw, the end of the fixture is connected to the lower alveolar nerve. There is a serious problem that the nerve is paralyzed by touching it.

Accordingly, the fixture is installed to be inclined at a predetermined angle in a portion corresponding to the posterior side of the gum, so that the fastening part formed in the prosthesis and the fastening angle of the fixture are different from each other. Accordingly, some inclined abutments capable of mediating by simultaneously satisfying the installation angle of the fixture and the formation angle of the fastening part have been disclosed.

In detail, the conventional inclined abutment includes a coupling protrusion coupled to the upper end of the fixture, a margin portion provided on the upper side of the coupling portion and provided inside the soft tissue of the gum, and an inclined upward side of the margin portion provided to the coupling portion It includes a coupling portion to be coupled.

At this time, a second fastening pipe portion is formed corresponding to the first extending direction of the coupling protrusion so that the first fixing means for fastening with the fixture is inserted. In addition, the first fastening tube portion corresponding to the second extending direction of the coupling portion is inclined at a different angle from the second fastening tube portion so that a second fixing means for fastening with the fastening portion is inserted.

Conventionally, the inclined abutment is gripped through tweezers so that the sterilized or antibacterial-treated surface is not contaminated and moved to the upper end of the fixture, and then the first fixing means inserted into the inclined abutment is attached to the fixture. It is fixed inside by fastening.

However, when gripping using tweezers, there is a problem in that the slanted abutment is easily separated from the tweezers during movement because the fixing force to the inclined abutment is insufficient and the slanted abutment is easily separated from the tweezers and is contaminated by falling to the floor. In addition, since it was difficult for the operator to move the inclined abutment to an accurate implantation position, and it was difficult to provide a pressing force for closely supporting the inclined abutment toward the fixture, there was a problem in that the precision of implantation was reduced.

Moreover, when fastening with the fixture, since the driver for rotating the fixing means is inserted at an inclined angle corresponding to the first extension direction, it is difficult to support and fasten the inclined abutment at an accurate inclination angle.

For this reason, when the angle of fastening with the fixture is twisted, the first fixing means may be separated from the fixture or the fastening part may be damaged. In addition, when the inclined abutment or the fixing means is separated from the fastening part by the operator's mistake in the oral cavity during the fastening process of the inclined abutment, the prosthetic subject swallows it or is inserted into the airway, resulting in a serious human accident. there was a problem with
