Articulator

Abstract

An articulator for dental use includes a first base, a second base coupled to the first base, and an occlusion pin configured to couple the first base and the second base in a closed position. The first base includes a first base body including a first groove configured to receive plaster, a first hinge portion configured to extend outwardly from one end of the first base body, and a plurality of pin holes. The second base includes a second base body including a second groove configured to receive the plaster, a second hinge portion configured to extend outwardly from one end of the second base body, and a plurality of guide pin holes. The second hinge portion is configured to couple to the first hinge portion via the occlusion pin in the closed position.

         17 . An articulator base comprising:
 a base body comprising an inwardly facing groove configured to receive a gypsum or plaster,   a hinge portion coupled to the base body and configured to extend outwardly from one end of the base body, and   a plurality of guide pin holes disposed in the inwardly facing groove of the base body,   wherein the hinge portion is configured to couple to a hinge portion of a second articulator base that is to be coupled to the articulator base, and   wherein the base body of the articulator base includes one or more guide pin markers on a side wall of the base body.   
     
     
         18 . The articulator base according to  claim 17 ,
 wherein the hinge portion of the base body of the articulator base comprises a pair of extension couplers disposed on an extension part coupled to one end of the base body, the pair of extension couplers including a left first extension coupler and a right first extension coupler; and   wherein the left first extension coupler of the hinge portion of the articulator base is configured to couple to a left second extension coupler of a hinge portion of the second articulator base that is to be coupled to the articulator base, and the right first extension coupler of the hinge portion of the articulator base is configured to couple to a right second extension coupler of the hinge portion of the second articulator base that is to be coupled to the articulator base.   
     
     
         19 . The articulator base according to  claim 17 , wherein the groove of the base body of the articulator base further comprises a plurality of protrusions on a bottom surface of the groove. 
     
     
         20 . The articulator base according to  claim 17 , wherein the base body of the articulator base further comprises a plurality of overflow prevention walls surrounding the groove to prevent overflows of the gypsum or plaster that is applied. 
     
     
         21 . The articulator base according to  claim 17 , wherein the base body of the articulator base further comprises an interlocking part configured to receive an occlusion pin. 
     
     
         22 . The articulator base according to  claim 21 , wherein the occlusion pin comprises an elongated body and a protrusion extension point at one end of the elongated body, and wherein the protrusion extension point includes an angle with respect to a center line of the elongated body. 
     
     
         23 . The articulator base according to  claim 22 , wherein the protrusion extension point of the occlusion pin includes a predetermined angle of about 20 to 30 degrees with respect to the elongated body. 
     
     
         24 . The articulator base according to  claim 23 , wherein the occlusion pin includes one or more occlusion guide channels disposed in a longitudinal direction along an elongated body of the occlusion pin, and wherein one or more occlusion guide channels are configured to couple the occlusion pin to interlocking parts of the base body of the articulator base.
