ARCH WIRE, PREPARATION THEREFOR AND SPHERICAL PLATE THEREFOR

摘要

PROBLEM TO BE SOLVED: To provide a Monson spherical plate where an arch chart for arch wire preparation is plotted capable of obstructing a Christensen phenomenon, smoothing muscles around the jaw and obstructing the change of an occlusion plane, an arch wire provided with a curve corresponding to an occlusion plane curve and the preparation method. SOLUTION: On the Monson spherical plate, an upper jaw dental arch curve 1 on a concave surface and a lower jaw dental arch curve on a convex surface are plotted and this arch wire for which a Monson curve is made along the arch is prepared.
