Double-blind study for evaluation of complete dentures made by two techniques with and without face-bow.

The aim of this article was to compare complete dentures made by two techniques: with and without face-bow. Five edentulous subjects were selected and each one received two pairs of complete dentures. Dentures were made from duplicated casts and each one followed different techniques. One technique used face-bow and artificial teeth. Teeth were set using individualized wax ridges as guides. The other technique used an articulator, which avoids face-bow and teeth were set by the cast-analysis method. The number of occlusal contacts in centric relation and excursive movements were registered, as well as the opinion of patients regarding denture bearing during oral functions. Both groups presented balanced dentures, but the technique that avoids face-bow presented better results regarding to esthetics, comfort and stability. Balanced occlusion was provided even without face-bow and could be an alternative to obtain adequate complete dentures.
