Efficacy and risk factors of traditional denture restoration versus biofunctional complete denture restoration system

Objective: This study was designed to determine the efficacy of a traditional complete denture and a biofunctional prosthetic system of a complete denture, and risk factors affecting their efficacy. Methods: A retrospective analysis was performed on 95 patients with total dentition loss admitted to our hospital from January 2015 to June 2022. Among them, 45 patients who received traditional dentures were assigned to a control group, and the other 50 who received a biofunctional prosthetic system with complete dentures were assigned to an observation group. The clinical efficacy was compared between the two groups before and after treatment, and the masticatory function indexes and comfort scores of the two groups were also compared. Logistics regression analysis was conducted to analyze the risk factors affecting the efficacy of patients. Results: The observation group showed a higher total effective rate than the control group (P<0.05). After treatment, the observation group showed notably higher masticatory efficiency and absorbance of masticatory substances than the control group (P<0.05). In addition, the denture tenderness point in the observation group was notably lower than that in the control group (P<0.05). After treatment, the observation group had notably higher scores in General Comfort Questionnaire than the control group (P<0.05). Moreover, according to Logistics regression analysis, older age, dentition loss caused by tooth defect, smoking history and traditional denture restoration were independent risk factors for ineffective treatment. Conclusion: The biofunctional prosthetic system of complete dentures can better improve the masticatory function and enhance the comfort of patients with total dentition loss, and with good efficacy.

Automated summary

This study compared the efficacy of a traditional complete denture and a biofunctional prosthetic system of a complete denture, and identified risk factors affecting their efficacy. The results showed that the biofunctional prosthetic system had better outcomes in improving masticatory function and patient comfort compared to the traditional denture. Logistic regression analysis revealed that older age, dentition loss caused by tooth defect, smoking history, and traditional denture restoration were independent risk factors for ineffective treatment.
