The purpose of this study was to investigate the physiological recovery for distorted tissues with tissue conditioners. The changes of pressure-displacement in the denture-supporting tissues were measured using a new device with strain gauges placed on the cantilever during tissue conditioning. To deform the underlying soft tissues, experimental dentures were fitted to six subjects with missing maxillary or mandibular first molar. Recovery of the distorted tissues was performed by one of two methods. In the first method, experimental dentures were removed from the mouth. In the second, a tissue conditioning treatment was used. Then the recovery effectiveness of the two methods was compared with measurement of pressure-displacement. The conclusions were as follows: 1. By the calibration tests using the new device, it was confirmed that pressure-displacement could be accurately measured. 2. The effectiveness of tissue conditioning could be quantitatively estimated using the new device. 3. Distorted tissues were recovered with tissue conditioning, and the pressure-displacement became uniform. 4. There were no significant differences (p>0.05) of pressure-displacement between the tissue conditioning and removal of the experimental dentures.
