Method for manufacturing the one body abutment of an implant

Abstract

The invention discloses a method for manufacturing the one body abutment of an implant. Particularly, the method of manufacturing an abutment of an artificial tooth, includes an implant fixture installed in a jaw bone and a crown defining a contour thereof. The abutment is fixed to the implant fixture to connect the implant fixture to the crown. A three-dimensional image of an oral cavity of a patient is generated on a computer by 3D scanning of a dental plate of plaster. A virtual tooth is designed using the image of the oral cavity, in consideration of a row of teeth in a region from which a tooth is missing, the height of adjacent teeth and alignment with an upper or lower tooth. The shape of the abutment is designed according to the shape of the designed virtual tooth. Data on the designed abutment are transmitted to a precision machine. The designed abutment is cut using the precision machine to have a one body structure.

Description

technical field [0001] The present invention relates to the manufacturing method of the artificial tooth that is used to replace the natural tooth, relates to a kind of manufacturing method of the artificial tooth that is made of implant fixed body, abutment (abutment) and tooth crown. The present invention particularly relates to a method for manufacturing an abutment for connecting the above-mentioned dental implant fixture and the above-mentioned dental crown. [0002] In the process of manufacturing the above-mentioned abutment, the present invention relates to a method of manufacturing the abutment: since the manufacturing is based on the three-dimensionally designed virtual teeth, the individual characteristics of the patient are considered and the abutment is formed by a precision machining machine. The one-piece abutment thus enables mass production of abutments with high functionality. Background technique [0003] The invention relates to a manufacturing method of...

AI Technical Summary

Problems solved by technology

However, for the abutment with the above-mentioned structure, since the load transmitted to the crown is directly transmitted to the screw connection part, the phenomenon of loose connection of the screw frequently occurs, and in severe cases, the screw itself may be damaged and the screw connection may be damaged. danger of exodus

Also, if a continuous load is applied to the abutment, that is, the process of chewing food with the teeth is repeated, the micro vibrations that occur during this process will naturally loosen the screws fixed to the implant fixture

In this way, the operation needs to be performed again with a new implant, thus causing a lot of pain and inconvenience to the patient

[0009] In order to prevent such a problem, the patient needs to regularly check the connection state of the screw, which is very troublesome for the treating doctor and the patient, and the resulting economic burden cannot be ignored
