Abstract

Thirty patients were examined, selected and individual impression made. After the impressions made, the casts were mounted in a special apparathus the Gnathothensiometer to measure the differences among three different centric relation techniques. Technique 1 - A bite rim, refined with zinc-oxide-eugenol. Technique 2 - A bite rim, refined with zinc-oxide-eugenol plus a jig. Technique 3 - A bite frame with gauze and zinc-oxide-eugenol. According to the measurements, the technique more accurate, for register the centric relations, seem to be the one using the frame of Jones (Technique nº 3).
