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 tooth model-shaped 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 tooth model-shaped 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.

         10 . An occlusion correction improvement instrument, wherein a corrected Camper's plane of a patient is used in combination with a Camper's plane-acquiring device which can be acquired at any time, comprising:
 an upper mold-mounting member provided with a plate-shaped member so as to be parallel to the corrected Camper's plane when mounted on a maxillary tooth row of the patient; and   a lower mold-mounting member mountable on a mandible tooth row of the patient, the lower mold-mounting member including
 a pin-shaped projection portion which can be fixed by adjusting a position of the pin-shaped projection portion vertically and laterally with an angle of the pin-shaped projection portion relative to an upper surface of the lower mold-mounting member being kept at a fixed angle; 
 a sliding member, including an upper surface and a lower surface which are both smooth, flat surfaces, attached with the pin-shaped projection portion for smoothly and continuously sliding the position of the pin-shaped projection portion along the smooth, flat surface rightward or leftward relative to a median line of a maxilla, the sliding member configured to continuously adjust the attached pin-shaped projection portion to lie on the median line of the maxilla with the mandible tooth row of the patient kept parallel to the corrected Camper's plane, the pin-shaped projection portion projecting upward from the upper surface of the sliding member of the lower mold-mounting member mounted on the mandible so as to be moved continuously along the smooth, flat surfaces with a tip of the pin-shaped projection portion indicating whether the pin-shaped projection portion is located at the median line of the maxilla with the mandible tooth row of the patient kept parallel to the correct Camper's plane upon occurring a displacement of the mandible of the patient relative to the median line of the maxilla when the upper mold-mounting member is mounted on the maxillary tooth row of the patient and the lower mold-mounting member is mounted on the mandible tooth row of the patient, and 
   a fastening member for fastening the sliding member so as to fix the position of the pin-shaped projection portion, wherein the fastening member can be loosened for the sliding member to slide the position of the pin-shaped projection portion.
