[Gerber registration with functional impressions--a significant alternative in fabrication of complete denture?]

Gross occlusal discrepancies are noted frequently in complete dentures following registration which often necessities a new set up of posterior teeth. An examination was carried out to determine the extent to which these inaccuracies could be eliminated when a Gerber's registration was carried out with the help of functional impressions. It was found that occlusal relationships in dentures fabricated after registration with functional impressions and TMJ orientated mounting of the models to an articulator, could only slightly be improved as compared to the occlusal conditions observed in dentures fabricated after a manually assisted check bite. However, with regard to the attainment of an accurate and bilaterally balanced articulation, the described method proved significantly superior to an average set up resulting from a check bite.
