Abutment for Implant

Abstract

An abutment connecting a crown that forms an external form of an artificial tooth to a fixture embedded in a gum of a human, and comprising a body, a combination portion formed at an end of the body and combined with the fixture, a threaded portion formed at the body and penetrating through the body, a fixing screw being inserted into the threaded portion to couple the body to a processing device or a jig, a coupling hole formed at the body and penetrating through the body, a coupling unit being inserted into the coupling hole to connect the body and the fixture, and a sectional surface formed at an opposite portion to the combination portion and connected to the processing device or the jig, to position the body in the processing device or in the jig when the body is coupled to the processing device or the jig.

1 . An abutment for implant comprising:
 a body;   a combination portion formed at an end of the body and combined with the fixture;   a threaded portion formed at the body and penetrating through the body, a fixing screw being inserted into the threaded portion to couple the body to a processing device or a jig;   a coupling hole formed at the body and penetrating through the body, a coupling unit being inserted into the coupling hole to connect the body and the fixture; and   a sectional surface formed at an opposite portion to the combination portion and connected to the processing device or the jig, to position the body in the processing device or in the jig when the body is coupled to the processing device or the jig.   
     
     
         2 . The abutment of  claim 1 , further comprising an installation portion formed at another end of the body and installing the body in the processing device or the jig, and
 the sectional surface is formed at the installation portion.   
     
     
         3 . The abutment of  claim 2 , wherein the installation portion is taped as the sectional surface is far from the body. 
     
     
         4 . The abutment of  claim 2 , further comprising a recess portion formed between the body and the installation portion. 
     
     
         5 . The abutment of  claim 4 , wherein the installation portion has an outer diameter smaller than an outer diameter of the body. 
     
     
         6 . The abutment of  claim 2 , wherein the installation portion has a surface of a D shape or a polygonal shape. 
     
     
         7 . The abutment of  claim 4 , wherein the sectional surface is formed at a portion of a side of the body. 
     
     
         8 . The abutment according to  claim 7 , wherein the body has a surface of a letter D shape or a polygonal shape, which is in contact with the sectional surface.
