[Results of mechanical stresses from removable dentures on ridge mucosa and bone]

247 human cadaver jaws (obtained from 115 complete denture-wearers, 98 partial denture-wearers, 34 control persons) were examined histopathologically to determine if there is a correlation between tissue response and type of prosthetic management. The pathohistological changes of tissue and bone were evaluated statistically according to sex, age and topography of maxilla and mandible. The highest number of pathological findings was associated with those complete dentures and partial dentures where the biomechanical principles of construction had not been observed. Age, sex and topography, however, do not reveal any significant influence on tissue and bone.
