Twin-Stage Procedure. Part 2: A clinical evaluation test.

The Twin-Stage Procedure was used to measure the amount of disocclusion reproduced on the articulator (in vitro) and in the mouth (in vivo). The results almost coincided, even without measurement of the condylar path By using this new procedure, quantitative control of the amount of disocclusion, which was previously impossible, has become a reality in daily clinical procedures. The amount of disocclusion occurring on an articulator coincided with the amount of disocclusion intraorally; therefore, the Twin-Stage Procedure is considered to be highly reliable.
