Description

Dental implant procedure kit {Dental implant procedure kit}

The present invention relates to a dental implant treatment kit, and more particularly, to a dental implant treatment kit used for flapless surgery.

Medical implant refers to a replacement that restores when the original human tissue is lost, but in dentistry, it refers to a series of procedures for implanting artificial teeth.

To replace the lost root (root), a fixture, which is a root made of titanium that does not react to the human body, is planted in the alveolar bone from which the tooth has been pulled out, and then the prosthesis is fixed to restore the function of the tooth. It is a procedure to do.

In the case of a general prosthesis or denture, the surrounding teeth and bones are damaged over time, but the implant does not damage the surrounding dental tissue, and it has the advantage that it can be used semi-permanently because it has the same function or shape as a natural tooth and does not cause caries.

Implant procedures vary depending on the type of fixture, but after drilling the placement position using a predetermined drill, the fixture is placed in the alveolar bone and bone fused to the bone, and then the abutment is joined to the fixture, and then abutment It is usually done by placing the final prosthesis on the wall.

Dental implants improve the function of dentures in patients with partial and complete dentition, as well as single defective tooth restorations, improve the aesthetic aspect of dental prosthetic restorations, and further disperse excessive stress applied to the surrounding supporting bone tissue. In addition to shikim, it helps stabilize the dentition.

In general, these dental implants include a fixture that is placed as an artificial tooth root, an abutment that is bonded to the fixture, an abutment screw that fixes the abutment to the fixture, and the abutment. Includes a crown that becomes. Here, before the abutment is bonded to the fixture, that is, during the period until the fixture is bone-fused to the alveolar bone, the temporary abutment is coupled to the fixture to maintain the bonded state.

A fixture, which is a component of a dental implant, plays a role of an artificial tooth root as a part that is inserted into a perforated groove formed in an alveolar bone using a drill or the like at a location where the implant is performed. Therefore, the fixture must be firmly placed in the alveolar bone.

Accordingly, a threaded portion (screw thread) is formed on the outer surface of the fixture so that it can be firmly coupled to the inner wall portion of the alveolar bone forming the perforated groove. These threads are inserted into the alveolar bone and not only allow the fixture and the alveolar bone to be firmly coupled, but also increase the contact area between the fixture and the alveolar bone, thereby reinforcing the fixation force of the fixture to the alveolar bone, especially the initial stability. do.

In this way, in the dental implant procedure, a hole is drilled in the alveolar bone using a drill, a fixture is placed in the hole, and when bone fusion proceeds, the abutment is bonded to the fixture, and the artificial tooth (prosthesis) is finally covered. It proceeds to steps.

On the other hand, it is known that the success rate of implantation in the maxillary posterior region during the above-described dental implant implantation procedure is relatively low compared to the success rate in other regions, for example, the mandibular posterior region. ), so it is not easy to place the fixture.

The upper part of the maxillary posterior region, more precisely, the sinus, which exists between the upper molars and the nose, is an empty space surrounded by mucous membranes and expands as it descends and expands when a tooth is lost. The amount of bone that can be used to place the fixture becomes insufficient, and this makes it difficult to place the fixture in the maxillary posterior teeth.

Therefore, after forming a space by elevating the sinus membrane, a bone graft material is implanted in the secured space and a fixture is implanted therein, and thus the method of elevating the sinus membrane There are two approaches: a crestal approach and a lateral approach.

The lateral approach is a method used when the remaining bone at the site of implantation is very insufficient. A hole is formed on the side of the maxillary sinus to elevate the inner membrane of the maxillary sinus, and then a bone graft is transplanted through the hole. This lateral approach takes a lot of time to perform the procedure compared to the dental adjustment approach, and swelling may occur at the treatment site.

The crestal approach is a method used when a certain amount of remaining bone is secured in the implant site. After forming a guide groove of a certain depth toward the sinus membrane in the alveolar bone of the maxilla, After positioning the osteotom, the osteotom is hit with a hammer to allow the osteotom to penetrate the remaining alveolar bone to form a through hole in the alveolar bone, and then the maxillary sinus membrane through the osteotom. After lifting the (sinus membrane), the bone graft material is supplied little by little between the alveolar bone and the sinus membrane through the through hole.

However, the osteotome used in this crestal approach receives the impact force from the hammer and advances, so the impact is applied to the surrounding alveolar bone where the impact force is applied during the striking process, causing the alveolar bone to fall into a large area in the process of piercing the alveolar bone. I can.

If the alveolar bone falls to a large area in this way, great pain is involved for the recipient (patient), and many cracks may occur in the surrounding alveolar bone, and the recovery time for the fusion of the fixture and the alveolar bone may be lengthened, and the hammer hits As a result, there is a problem that side effects such as the patient complaining of dizziness occur.

In addition, there is a problem in that the sinus membrane may be damaged due to the rapid movement of the osteotome when the operator transmits excessive impact force to the osteotome during the procedure.
