The effect of the wearing of complete dentures on facial morphology has been the object of a series of longitudinal studies by the present author.1-4 The resorption of the residual alveolar ridges during a seven-year period of denture wear was found to have caused a pronounced reduction of the pre-extraction morphologic face height and an accompanying although less marked reduction in the rest face height.2 In subjects provided with complete upper and partial lower free-end dentures, the decrease in facial height was, on the average, only half that noted in the complete denture group. The adaptive changes in the rest face height to the alterations in the morphologic face height have been confirmed in several other studies.5-10
