Observation of horizontal mandibular positions in an edentulous patient using a digital gothic arch tracer: a clinical report.

Dentures were fabricated for a 73-year-old woman using porcelain 20-degree maxillary posterior teeth and acrylic resin flat planes in the mandibular posterior region. A digital gothic arch tracing device was used to observe the horizontal mandibular positions before insertion and to evaluate the therapeutic effect of the diagnostic dentures at 1 and 3 months after insertion.
