Denture adhesives - their effect on the mobility of full upper dentures during chewing. A cineradiographic study.

Using cineradiographic technique an assessment is made of the denture mobility during function in the upper jaw for full denture wearers without and using two types of denture adhesives. One of them with a new formula. Ten randomly selected edentulous patients with moderate alveolar ridge resorption took part in the study. They were rehabilitated with dentures of conventional design in the upper jaw. Cineradiographic registrations were performed in lateral projection without and with the two types of adhesives supplied to the denture base. The analysis of the cineradiographic films disclosed no significant differences for the denture mobility. Neither between the situation without and with denture adhesive nor between the two adhesives. This indicates an obvious limited effect of the denture adhesives, at least for denture wearers with moderate resorption of their alveolar ridges. The only positive effect of the adhesives discovered was a limited number of vertical loosening drops of the distal parts of the denture when the seal was broken.
