Patent ID: 8347517

Claim:
A measuring device of transparent flexible material for determining parameters characteristic of a person's mouth cavity, jaw and oral configuration for the production of dental prostheses, comprising a circular section (1) having a diameter representing the distance between the outside surfaces of the right side and left side molars, an interproximal gauge rule (2) forming a first measuring arm; the circle section (1) transitions and forms a single section with the interproximal gauge rule (2); the interproximal gauge rule (2) tapers distally, starting from the circular section (1) and includes two straight longitudinal sides, forming a first scale and a second scale; the first scale represents a graduated scale (3) for measuring length on a graduated scale; the second scale (4) represents a graduated scale (4) for measuring the distance of tooth gaps with distance indications between the two longitudinal sides at corresponding locations, the extension of one of the two straight longitudinal sides dividing the circular section into two halves in the form of a visible straight line.
