Description

Prosthesis-mounted healing abutment {PROSTHETIC-MOUNTED TYPE HEALING ABUTMENT}

The present invention relates to a prosthetic-mounted healing abutment.

In more detail, the lower body and the multi-cap are easily combined and separated by the coupling ring, so that the already fixed lower body can be used by simply removing the multi-cap as needed. It's about men.

When natural teeth cannot be used due to various diseases, conventionally, a bridge procedure was performed in which dentures were inserted through dental procedures or the natural teeth were removed, and the missing part was covered with metal using the surrounding teeth as columns.

However, such a procedure has several problems such as poor chewing power of dentures or bridge-treated artificial teeth and adversely affecting surrounding teeth.

Accordingly, an implant procedure has emerged as a method of advanced dental procedures. Such implants can be broadly divided into subdivisions: a fixture that is placed in the alveolar bone as the root of a tooth, a prosthesis that is the head of a tooth, and a column that connects the fixture to the prosthesis, that is, the abutment. It consists of an abutment.

The general implant procedure steps include removing the damaged natural tooth and inserting a fixture into the frame by penetrating the gum in its place, screwing the lower part of the abutment in the center of the fixture where the female thread is formed, and the step of fixing the abutment. It includes the step of fixing the prosthesis (artificial tooth) on the upper part.

However, before the step of screwing the abutment in the center of the fixture, a middle gum healing abutment that penetrates the gum is connected so that the abutment can be well connected to the fixture, which is called a healing abutment. If the alveolar bones and gums are weak, after installing the fixture, wait several months with the gums covered, then incise the gums to connect the healing abutment to the fixture. After connecting and waiting for several months, the healing abutment is removed from the fixture after the gum is fully recovered, and instead, the abutment is fastened and a prosthesis is installed.

As such, the healing abutment of the implant helps to heal the gums so that the abutment is properly installed in place, literally, the fixture is osseointegrated to the alveolar bone, and it is temporarily adopted while the gum is recovering. It plays a role of healing into shape.

In the implant procedure, an implanted groove is formed using a tool such as a drill to embed a fixture in the alveolar bone from which the teeth are missing, and tapping is performed as an optional operation for firmly implanting the fixture inside the implanted groove. . Thereafter, after the fixture is implanted into the implanted groove, a cover screw is fastened to prevent foreign substances from penetrating into the fixture, and the gums are covered and sealed to complete the primary surgery. Thereafter, as a secondary surgery, after about 3 to 6 months have elapsed, the closed gum is incised again and the cover screw is removed from the fixture.After considering the type of abutment to be fastened, a healing abutment is selected. Tighten. The healing abutment at this time is to ensure that the gums are formed cleanly above the fixture before fastening the abutment to the fixture, and after about 2 to 3 weeks after fastening, the gums suitable for the abutment are created, After removing the butt, attach the abutment, perform the impression (making the pattern of the artificial tooth), and then combine the healing abutment again while making the artificial tooth prosthesis. Thereafter, when fabrication of the artificial tooth prosthesis is completed, the healing abutment is removed from the tooth, and then the abutment is recombined, and the artificial tooth prosthesis manufactured on the upper side of the combined abutment is combined to complete the implant procedure.

In this way, in the process of manufacturing an artificial tooth prosthesis in a shape suitable for the patient's oral structure and combining the produced artificial tooth prosthesis with the abutment, the healing abutment for maintaining the gums during the gum recovery period, and impression work There is a problem that the work is very inefficient because the work of fastening and removing the healing abutment is repeatedly performed, such as the removal of the healing abutment for and the fastening of the healing abutment for maintaining the gums during the impression production period.
