[The stability of complete dentures in the construction of functional movement patterns].

In a cross-sectional study involving 185 full denture wearers, the stability of upper and lower dentures was determined by means of active test movements according to Herbst. The percentages of instable dentures and their confidence intervals were calculated. It was found that all sections of upper full dentures can be regarded as equal with regard to stability, whereas the sections of lower full dentures showed considerable differences. Finally, practice-relevant conclusions are drawn from the results of the present study.
