About

The objective of this study is to compare the canine guidance (CG) and bilateral balanced occlusion (BBO) on denture satisfaction and kinesiographic parameters of complete denture wearers, by means of a cross-over trial. Edentulous patients will receive new maxillary and mandibular complete dentures and, after the intraoral adjustments and adaptation period, will randomly receive a sequence of occlusal schemes: BBO followed by CG, or CG followed by BBO.
