Resumo
The mucosa that covers the residual ridges of edentulous patients may present some distortion or dis-
placement when occlusal loading is applied in complete dentures. This distortion and movement of the denture can re-
sult in acceleration of residual ridge resorption and loss of retention and stability. The aim of this study was to analyze
the pattern of upper complete denture movement related to underlying mucosa displacement. A sample of 10 complete
denture wearers was randomly selected, which had acceptable upper and lower dentures and normal volume and re-
silience of residual ridges. The kinesiographic instrument K6-I Diagnostic System ® was used to measure denture
movements, according to the method proposed by Maeda et al. 7 , 1984. Denture movements were measured under the
following experimental conditions: (A) 3 maximum voluntary clenching cycles and (B) unilateral chewing for 20 sec-
onds. The results showed that under physiological load, oral mucosa distortion has two distinct phases: a fast initial
displacement as load is applied and a slower and incomplete recovery when load is removed. Intermittent loading such
as chewing progressively reduces the magnitude of the denture displacement and the recovery of the mucosa is gradu-
ally more incomplete.
