Description

Dental implant component recognition and inspection system and method {Dental implant component recognition system and method}

The present invention relates to a system and method for both recognition and inspection of dental implant components, and more particularly, it is possible to accurately recognize a dental implant component used in a dental implant procedure and inspect the state of the dental implant component. It relates to a system and method for both recognition and inspection of dental implant components that can be used.

An implant originally refers to a substitute that restores human tissue when it is lost, but in dentistry, it refers to a series of procedures that implant artificial teeth.

To replace the lost root (root), a fixture made of titanium, etc., which does not have a negative reaction to the human body, is planted in the alveolar bone from which the tooth has escaped, and then the artificial tooth is fixed to restore the function of the tooth. It is a procedure to do.

In the case of general prostheses or dentures, the surrounding teeth and bones are damaged over time, but implants do not damage the surrounding tooth tissue.

Artificial teeth treatment (also referred to as implant or implant treatment) varies depending on the type of fixture, but after drilling an implantation location using a predetermined drill, the fixture is placed in the alveolar bone to osseointegrate into the bone, and then the abutment is placed on the fixture. After joining the abutment, it is usually completed by placing the final prosthesis on the abutment.

Dental implants improve the function of dentures for partially and completely edentulous patients as well as single missing tooth restorations, improve the aesthetics of dental prosthetic restorations, and further dissipate excessive stress on the surrounding supporting bone tissue. It also helps to stabilize the dentition.

These dental implants generally include a fixture to be placed as an artificial tooth root, an abutment coupled to the fixture, and an abutment screw for fixing the abutment to the fixture, and the abutment is coupled to the abutment. including artificial teeth. Here, before the abutment is coupled to the fixture, that is, during the period until the fixture is osseointegrated to the alveolar bone, the abutment is coupled to the fixture to maintain the coupled state.

A fixture, which is a component of a dental implant, is placed in a drill hole formed in the alveolar bone by using a drill or the like at a position where the implant is operated, and plays the role of an artificial tooth root. Therefore, the fixture must be firmly implanted in the alveolar bone.

On the other hand, the components of the dental implant are very small in size, so even if the components of the dental implant of different sizes are provided during the procedure, there is a problem in that it is difficult for the operator to easily recognize them. For example, in the case of a fixture, it is divided into several types depending on the length and diameter. Since the difference between the length and the diameter is divided in millimeters (mm), even if a fixture other than the fixture planned in advance is provided during the procedure, the operator is difficult to perceive with the naked eye.
