Description

A temporary abutment for bone augmentation

The present invention relates to a temporary abutment for bone augmentation surgery, more specifically, the installation of the temporary abutment and the bone augmentation technique can be performed at the same time, the bone augmentation technique of the alveolar bone is used, crushed bone is simplified, The present invention relates to a temporary abutment for bone distension surgery in which the bone distension procedure can be performed more precisely.

In general, the implant system (dental implant system) is a fixture that is implanted in the alveolar bone in place of the root of the damaged tooth removed from the alveolar bone (fixture), and coupled to the media to fix the artificial tooth (crown) Prostheses, such as abutments, are provided, and assistive devices such as mounts, cover screws, healing abutments, positioning cylinders, etc., until the implant is completed. Is used.

In connection with such an implant system, the applicant has registered Korean Patent Publication No. 10-0310318 "Dental Prosthetics", No. 10-0394071 "Artificial Teeth Fixture and Manufacturing Method", No. 10-0545853 "Crown Implant" Abutments ", 10-0545852" Abutments for bridge implants ", 10-0539415" Abutments for dental implants and aesthetic surface treatment methods thereof, "10-0540447 Crown type implants and the Korean Utility Model Publication No. 20-0383249, "Dental implant carcass" and the like have been proposed.

On the other hand, the implanted body constituting the implant system must be stable and firmly placed in the alveolar bone so that the artificial tooth can hold the position and perform the function that the permanent tooth of the body performs. By the way, in the alveolar bone where the media is placed, bone resorption progresses due to extraction, or bone resorption due to bone aging due to aging of the body and other reasons is insufficient. When the width is smaller than the thickness or width for embedding the planting body, the implantation of the planting body cannot be made stable and firmly, and thus, the bone expansion technique is performed to supplement the planting body.

Bone augmentation is performed to compensate for the lack of residual bone in the alveolar bone, and there are crushed bone grafts and block bone grafts, which are mainly performed to form alveolar bone at the localized area. The procedure is performed when there is little remaining bone of alveolar bone or when the thickness of alveolar bone where the media can be placed is less than 5 mm. The bone is extracted from cartilage tissue of the body as a block and fixed to the site of implantation. This is how you do it.

Here, the crushed bone graft, which is performed when there is vertical bone absorption in the tongue or the lateral direction of the alveolar bone, is filled with a fine-thickness membrane after filling a predetermined amount of the crushed bone in the alveolar bone where the bone is absorbed. The procedure was performed by covering a certain portion of the alveolar bone including the clavicle to maintain the shape of the bone dilation site. As described above, the process of covering the alveolar bone with a micro-thick film included a problem that the bone dilation technique was troublesome. In addition, in the case of implanting the media into the alveolar bone and performing the crushed bone graft, the prosthetic teeth could not be prosthetic as the alveolar bone was covered with the crushed bone and the micro-thickness membrane. There was a hassle to re-open the alveolar bone for the prosthesis.

In contrast, block bone graft is performed by fastening the block bone to the site where vertical / horizontal bone absorption occurs using a fastener such as a screw, and removing the fastener such as a screw once the bone fusion is completed according to the block bone. It was necessary to prepare a separate block bone as described above, there was a problem that the bone expansion technique is complicated and cumbersome as the work to join the block bone using a screw is required.

Therefore, the present invention is to improve the problems of the prior art, by having an abutment having a stick-shaped skeletal piece having the property of bending deformation so that the skeletal piece serves as an external skeleton of the alveolar bone is not enough bone tissue The bone expansion procedure of the alveolar bone using crushed bone is simplified, and the operation is simplified as the abutment is installed or removed at the same time as fastening or detaching the abutment to the media placed in the alveolar bone and the bone expansion is performed. The purpose of the present invention is to provide a temporary abutment for a new type of bone augmentation technique in which the bone augmentation technique can be performed more precisely as the skeletal piece can be easily bent and deformed according to the bone augmentation technique.
