Occlusion correction improvement instrument and correction improvement method using the instrument

Abstract

An occlusion correction improvement instrument includes an upper mold-mounting member provided with a plate-shaped member that is parallel to a Camper's plane of an upper model having a makeup surface of a maxillary tooth row and with a plane parallel to the Camper's plane when the upper mold-mounting member has been mounted on the upper model; and a lower mold-mounting member mountable on a lower model having a makeup surface of a mandible tooth row and provided with a pin-shaped projection portion that can be fixed, with a position thereof adjusted from side to side and up and down, and with an adjustment member that can adjust a position of the lower mold-mounting member relative to the upper mold-mounting member on the plane parallel to the Camper's plane, with the projection portion abut on the plate-shaped member of the upper mold-mounting member.

       5 . An occlusion correction improvement instrument according to  claim 1 , wherein the projection has a distal end formed into a semi-circular shape in cross section.  
   
   
       6 . An occlusion correction improvement instrument according to  claim 2 , wherein the projection has a distal end formed into a semi-circular shape in cross section.  
   
   
       7 . An occlusion correction improvement instrument according to  claim 3 , wherein the projection has a distal end formed into a semi-circular shape in cross section.  
   
   
       8 . An occlusion correction improvement instrument according to  claim 4 , wherein the projection has a distal end formed into a semi-circular shape in cross section.  
   
   
       9 . An occlusion correction improvement method comprising: 
 a step of acquiring a plane parallel to a Camper's plane of an upper model having a makeup surface of a maxillary tooth row;    a step of forming an upper mold-mounting member that comprises an upper frame mountable on the upper model and a plate-shaped member attached to the upper frame in parallel to the parallel plane;    a step of forming a lower mold-mounting member that comprises a lower frame mountable on a lower model having a makeup surface of a mandible tooth row and an adjustment member attached to the lower model and provided with a pin-shaped projection portion that is movable side to side and up and down relative to the lower frame and capable of abutting on the plate-shaped member of the upper mold-mounting member; and    a step of correction including adjustment of a position of the projection portion, adjustment of a position of the lower mold-mounting member relative to the upper mold-mounting member in the presence of a change of the relative position from a state wherein the projection portion is abut on the plate-shaped member in a neighborhood of a center portion thereof and a pretreatment of excavation or prosthesis.    
   
   
       10 . An occlusion correction improvement method according to  claim 9 , wherein the plate-shaped member is mounted on the upper mold-mounting member using a jig for acquiring a plane parallel to the Camper's plane of the upper model at the step of forming the upper mold-mounting member.  
   
   
       11 . An occlusion correction improvement method according to  claim 9 , wherein the lower mold-mounting member is provided with a plate member having a frame body, and the projection portion has a proximal part helically engaged with the plate member so as to be movable vertically relative to the plate member and horizontally relative to the frame body at the step of forming the lower mold-mounting member.
