Description

Dental implant guide device, Dental implant guide device manufacturing system, and its manufacturing method

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dental implant guide apparatus, a dental implant guide apparatus manufacturing system, and a manufacturing method thereof, and more particularly, to a dental implant guide apparatus, An implant treatment guide device, a manufacturing system for manufacturing the dental implant guide device, and a manufacturing method thereof.

A dental implant is a substitute that restores when the original tissue is lost, but in dentists it refers to a series of procedures for implanting an artificial tooth.

In order to replace the missing root (root), a tooth fixture, made of titanium or the like, which has no rejection to the human body, is planted in the alveolar bone that has exited the tooth, and then the artificial tooth is fixed to restore the function of the tooth .

In general prostheses or dentures, the surrounding teeth and bones are damaged over time, but the implants do not injure the surrounding dental tissue, and they have the same function and shape as the natural teeth, but do not have cavities. Therefore, they can be used semi-permanently.

The artificial tooth procedure (also referred to as an implant or implant procedure) varies depending on the type of fixture, but after a predetermined drill is used to puncture the fixation position, the fixture is placed on the alveolar bone to perform an artificial fusion to the bone, After the abutments are combined, it is common to finish the abutment with a final prosthesis.

Dental implants enhance the function of dentures in single-tooth restorations, as well as in partial and total toothless patients, improve the aesthetic aspects of dental prosthesis restoration, and further dissipate excessive stresses on the surrounding supporting bone tissue It helps to stabilize the dentition as well as sikim.

On the other hand, in order to improve the accuracy of the implant procedure during the implant procedure, simulation and treatment planning are accompanied. Accurate data on the oral area of the subject is essential for these simulated and planned procedures.

Generally, a method of acquiring stereoscopic image data by capturing an image of a mouth area of a subject by using a computed tomography (CT) apparatus is used to acquire data on the mouth area of the subject.

However, the CT data obtained from the computed tomography (CT) apparatus has advantages in that it can accurately grasp the shape of the bones of the patient, and it is difficult to grasp the shape of the gums accurately and various types of restorations And the image may be distorted by the implant.

Therefore, after obtaining the model data by scanning the gypsum board made of the internal shape of the patient's body obtained using the impression body with a three-dimensional scanner or the like, the CT data and the model data are superimposed, Hybrid data that replaces the area with model data is used in simulation.

However, since the dental implant guide prepared according to the result of the post-mock procedure is delivered to the practitioner (dentist) in the mock procedure, the tooth plaster bone guide and the dental implant guide are manufactured.
