Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dental implant load applying device,

The present invention relates to a dental implant load applying apparatus.

Implant is an artificial tooth, which is a dental treatment method that restores the function of the natural teeth through surgery to the defect of the tooth. It can be used semi-permanently, and it is firmly fixed to the gum bone, so it does not interfere with food intake because it has excellent masticatory power. In addition, when the implant is placed, it is possible to prevent the tooth from moving into the hollow space of the gum after loss of the tooth, and it is possible to maintain the health and the preservation of the gum like a natural tooth. Dental implant technology has grown rapidly after the concept of the 1960s has been established and has become a representative technology of dental restorative treatment nowadays, and it has become so common that it is designated as a salary item of National Health Insurance.

When chewing food with implantable artificial teeth, such as implants (chewing), the artificial teeth are subjected to considerable force, such as applying a load to the screws that hold the tooth and the pedestal to the implant root , And in the worst case, one or more of the screws that make up the implant are bent to cause a micro gap between the components. In this case, when the oral fluid reaches the inside of the dental implant system through such a micro gap, there is a risk of various infections. In addition, due to the movement of the components of the implant, the screw is repeatedly elongated. It may be loose or broken. Therefore, in order to prevent this, a fatigue test is generally required to find out how long an implant can withstand a similar situation where the actual masticatory force acts.

The additional load of the currently used test equipment is loaded through the hemispherical load body in a state of being attached or resting on the end of the dental implant. The center of the hemisphere, ie, the center of the load, must be on the long axis of the dental implant. Such load force should be applied in a plane contact with the hemispherical load body according to the direction of the load force of the equipment, and it should be possible to apply the load at a rate of 14Hz per second without decreasing the load without restraint in the horizontal direction. A load applying device with a conventional plane does not have a restraining force in the horizontal direction, thereby reducing the additional load, resulting in poor test reliability and does not satisfy the ISO 14801: 2007 standard.

U.S. Patent Application Publication No. 2014-0053655 discloses a fatigue testing apparatus for dental implants using a fatigue testing apparatus that applies a load without reducing the additional load in a horizontal direction by using a ring- .

Considering these problems, there is a need for an apparatus for testing an implant fatigue load capable of imparting a fluid load in a similar manner to the temporomandibular joint.

A problem to be solved by the present invention is to improve the accuracy of a load application test on an implant specimen.

The problems of the present invention are not limited to the above-mentioned problems, and other problems not mentioned can be clearly understood by those skilled in the art from the following description.

According to an aspect of the present invention, there is provided a dental implant load applying unit including: a jig for fixing an implant specimen; A load applying unit arranged to be movable up and down from above the jig; And a load transmitting portion disposed in the load applying portion, applying a load to the implant specimen, and changing the angle depending on a contact position with the implant specimen.

The details of other embodiments are included in the detailed description and drawings.

According to the present invention, the accuracy of the load application test for the implant specimen can be improved.

The effects of the present invention are not limited to the effects mentioned above, and other effects not mentioned can be clearly understood by those skilled in the art from the description of the claims.
