Effect of treatment dentures on denture space in edentulous patients and its clinical evaluation

Abstract

Objective To investigate the effect of treatment dentures on changes in denture space in edentulous patients and to evaluate its clinical effect. Methods Twenty patients with treatment dentures were investigated with a questionnaire and Oral Health Impact Profile (OHIP-14) before and after treatment. The denture space, denture tissue surface, occlusal points, Gothic arch images, mucosal condition, lateral occlusal condition, bite force, retention and stability, patient mastication ability, denture satisfaction, and OHIP-14 score were collected for statistical analysis. Results After wearing treatment dentures, the denture space significantly improved, the tissue conditioners on the treatment denture gradually began to be distributed, and the occlusal points gradually became symmetrical. The gothic arch images showed that the joints, nerves, and muscles gradually stabilized. The mucosal condition changed to a healthy state. The lateral occlusal conditions were improved. There were also significant differences in the bite force, retention and stability, subjective and objective chewing ability, satisfaction with the denture and OHIP-14 score before and after treatment (P < 0.05). The objective chewing ability was positively correlated with the retention stability of the denture, the subjective chewing ability and the satisfaction of the denture, and it was negatively correlated with OHIP-14. Conclusion Treatment dentures could help to restore denture space to an ideal condition and improve the oral health of patients. This treatment could also improve the retention and stability of the denture and the chewing ability to improve patient satisfaction. This treatment has clinical application value and promotion potential.
