Abstract
Abstract A hand-operated gauge device used particularly by orthodontists and/or dental technicians for rapidly indicating and/or checking the interincisal angle between the upper and lower central incisors of a patient during or following orthodontic correctional procedures. The gauge device comprises a system of interconnected fixed and movable linkage arms or limbs arranged for temporary attachment to a pair of upper and lower central incisors, and has an angle-indicating scale calibrated to indicate the approximate included (interincisal) angle between the long axes of the teeth when in an occluded position.

An orthodontic gauge device for approximately determining the interincisal angle between a pair of relatively occlUded maxillary and mandibular central incisors comprising: a. a base frame defining a linear guideway; b. a first, elongated rectilinear limb carried by and projecting laterally outwardly from said base frame in perpendicular relation to said guideway; c. an elongated connector arm slidably carried in the guideway of said base frame and having a longitudinal axis disposed in right-angular relation to said first limb; d. a second, elongated rectilinear limb pivotally connected with said connector arm and extending laterally outwardly therefrom in coplanar relation to said first limb, said first and second limbs terminating in relatively spaced apart outer end portions, and one of said limbs being slidably adjustable relative to said base frame and said connector arm to vary the extent of lateral projection of its outer end portion from said base frame and said connector arm; e. tooth-engaging means carried at the outer end portion of each of said limbs for placing the longitudinal axes of the respective limbs in approximately perpendicular relation to planes tangent to the middle third of the labial surfaces of a pair of relatively occluded maxillary and mandibular central incisors; and f. an angle-indicating scale carried on said connector arm adjacent said second limb for indicating the approximate interincisal angle between a pair of relatively occluded maxillary and mandibular central incisors with which said means are engaged.
