Fifty-four complete-denture wearers were interviewed one year after they had been fitted with the dentures. Their opinions and reactions were noted and the answers given to standard questions were analysed for inter-correlations and for correlations with findings in earlier series of clinical and roentgenological investigations. Most of the patients were satisfied with the fit, aesthetic effect of the denture and ability to chew and speak. Many of the patients reported oral parafunctions. Roughly every fourth patient used sedatives because they felt restless and nervous.

Generally speaking partial dentures tend to be held in place by the presence of the remaining natural teeth and complete dentures tend to rely on muscular co-ordination and limited suction to stay in place. The maxilla very commonly has more favorable denture bearing anatomy as the ridge tends to be well formed and there is a larger area on the palate for suction to retain the denture. Conversely, the mandible tends to make lower dentures much less retentive due to the displacing presence of the tongue and the higher rate of resorption, frequently leading to significantly resorbed lower ridges. Disto-lingual regions tend to offer retention even in highly resorbed mandibles, and extension of the flange into these regions tends to produce a more retentive lower denture. An implant supported lower denture is another option for improving retention.
