Sectional dentures with electronic strain gauges attached were used as a means of evaluating the influence of posterior tooth position on the stability of a maxillary denture. The teeth were first arranged in normal relation for a series of chewing tests. The posterior teeth were then repositioned in crossbite relation for repetition of the tests. It could not be determined from this test that denture stability was improved by placing the posterior teeth in crossbite relation; many similar tests will be required before conclusions can be drawn.
