Oral Stereognosis in Patients with Completely Edentulous Jaws

Abstract

Thirty patients with completely edentulous jaws (the main group) and 30 patients without denture defects and treated oral cavity (the control group) were examined in order to study oral stereognosis. Standard Н. Landt sets were used. The rate of tactile assessment of the objects shape in the oral cavity of the patients with completely edentulous jaws was established to decrease by 2.6 times on average in comparison with the control group, and the percentage of correctness of the sample determination decreased by 44.4%. After one month of prosthodontic treatment of the patients with completely edentulous jaws with the use of complete laminar dentures, the rate of tactile assessment of the objects’ shape increased by 18.3% and the index of the correctness of the sample determination increased by 31.5%. The results of the oral stereognosis study showed that the duration of collecting and analysis of receptor signals of oral mucosa in the patients with completely edentulous jaws was longer than in the patients without denture defects. However, the tactile sensitivity of the oral mucosa had the ability to recover in one month after prosthodontic treatment with complete laminar dentures.
