Abstract

Abstract: PURPOSE: To investigate the effect of biological functional complete denture in the repair of middle-aged and elderly patients with missing dentition. METHODS: One hundred and one middle-aged and elderly patients with complete denture loss from February 2021 to March 2024 were retrospectively analyzed.They were divided into the control group (traditional complete denture, n=52) and the experimental group (biological functional complete denture, n=49) according to different restoration methods. Masticatory function, EMG activity of masticatory muscle, clinical efficacy, comfort level, oral health and patient satisfaction were compared between the two groups. RESULTS: Three months after treatment, the masticatory efficiency and absorbance of masticatory substances were significantly increased in 2 groups (P<0.05), and those in the experimental group were higher (P<0.05). Surface electromyography and asymmetry index (AI) of anterior temporal tract and masseter muscle in the experimental group were significantly lower than those in the control group(P<0.05), and the total effective rate was significantly higher than that in the control group(P<0.05). Three months after treatment, the scores of general comfort questionnaire(GCQ) in 2 groups were significantly increased (P<0.05), and those in the experimental group were higher (P<0.05); the score of oral health impact profile-14(OHIP-14) was decreased in both groups(P<0.05), and was lower in the experimental group (P<0.05). Satisfaction rate of patients in the experimental group was significantly higher than the control group (P<0.05). CONCLUSIONS: Biofunctional complete denture restoration can improve the comfort and oral health status of middle-aged and elderly patients with denture loss, enhance the masticatory function and the myoelectric activity of masticatory muscle, and improve patient satisfaction.
