It cannot, however, fully compensate for the efficiency of the natural dentition because (1) dentures are not fixed in place like teeth are and so have to be actively controlled by the muscles and (2) biting forces are greatly reduced (about 1/6th of the natural dentition) as the dentures are impinging on soft tissues. Due to the fact that the mucosa is uneven in compressibility, however, there will inevitably be an uneven distribution of loads during masticatory function. Consequently, for complete dentures to be retentive and stable, the retentive forces that hold the dentures in place must be greater than the ones aiming to displace it. Patients can, however, learn to control and coordinate their muscles so that the forces exerted are minimised or counter-acted to prevent such displacement. OVD = RVD - FWS = RVD - (2 to 4mm)).
