Description

Dental scan body holder {DENTAL SCAN BODY HOLDER}

The present disclosure (Disclosure) relates generally to a dental scan body holder and a scan body holding assembly including the same, and more particularly, a dental scan body holder capable of easily holding the scan body, and a scan body holding assembly including the same is about

In general, an implant is made of titanium and consists of a fixture to be placed in the jawbone, an abutment inserted and fixed to the fixture, and a prosthesis that is adhered to surround the upper portion of the abutment.

The fixture is placed in the jawbone and acts as a root, the prosthesis is manufactured in a shape similar to a tooth to form the appearance of an artificial tooth, and the abutment fixes the prosthesis to the fixture and transfers the load acting on the prosthesis to the fixture and jawbone. plays a role

On the other hand, the CAD cam system in dentistry manages all processes from design to product manufacturing with a computer. Since the reproducibility of the prosthesis used is so high that it is almost perfect, the production of prostheses using the CAD cam system is gradually increasing for accurate treatment.

Scanbody is a tool for displaying the position of the implant fixture on the computer screen through the implant/scanbody library during CAD work for implant prosthesis. After taking an impression in a conventional way, model scanning can be performed by connecting the scan body, or three-dimensional data can be obtained through oral scanning by directly connecting the scan body to the oral cavity.

On the other hand, implants are largely classified into a hexa type or a non-hexa type according to the assembly structure of the structure. The hexa type is a structure in which the assembly part of the fixture and the abutment is formed to correspond to each other in a polygonal shape, and the insertion direction of the abutment is specified. It is a structure in which the abutment is forcibly inserted into the fixture and assembled without directionality.

Since the direction in which the abutment is assembled is specified for the hexa type, when the scan body structure is assembled in a specific direction like the abutment, scan data is extracted and information between the scan body and the abutment is compared to the library (scan With the body as a reference point, all data information for prosthesis production) has the advantage of being able to design a prosthesis with the CAD CAM system.

On the other hand, when inserting at least a part of the dental scan body into the fixture and fixing it with a screw, there is a problem in that it is difficult to directly hold the scan body by hand and insert it into the fixture if the interdental space is narrow inside the posterior part. In addition, there is a problem in that it is difficult to tighten the screw by inserting the screwdriver into the posterior part after inserting the scan body into the fixture.

Also, even when moving the dental scan body into the oral cavity, it may be difficult to hold the scan body by hand and move it into the oral cavity.
