The impact of a newly constructed removable denture on the objective and subjective masticatory function

Abstract

Purpose: This study investigated the impact of the renewal of a removable prosthesis on the masticatory function by subjective and objective measures and its variation among the types of occlusal support. Methods: Seventy-eight patients who received newly fabricated removable denture patients participated in this study. For the objective assessment, masticatory performance was measured using test gummy jelly. For the subjective assessment, standardized questionnaires about food acceptability and the oral health-related quality of life (OHRQoL) were used. Pre-and post-insertion assessments were performed for each subject. Subjects were divided into three groups according to their posterior occlusion: with posterior occlusion (w/PO), without posterior occlusion (w/o PO) and edentulous. Wilcoxon's signed rank test was used to compare the pre-and post-treatment measurements of each assessment. The analysis of covariance and a multiple comparison were used to assess the effect of new dentures and differences due to occlusal support. Results: The masticatory performance, OHRQoL and food acceptability following prosthodontic treatment were significantly improved by new denture insertion. The masticatory performance among groups varied to a relative degree. The rate of masticatory performance improvement for edentulous subjects was twice that in w/PO subjects. The OHRQoL was significantly lower in the w/o PO and edentulous groups with old denture than patients w/ PO. The food acceptability improved most markedly in the edentulous group. Conclusions: The improvement in the masticatory performance by new denture insertion varied among types of occlusal support. Re-establishing the occlusal support of edentulous patients may help restore their OHRQoL and improve food acceptability.

Lower Masticatory Performance Is a Risk for the Development of the Metabolic Syndrome: The Suita Study

“…A previous study reported that masticatory performance decreases with aging (35). On the other hand, prosthodontic treatment can improve the masticatory performance (36,37) and use of dental services can prevent decreased masticatory performance (38). From the results of the present study, preventing the lower in masticatory performance by prosthodontic treatment and use of dental services may contribute to preventing the development of the MetS.…”

Deterioration of periodontal status affects declines in masticatory performance: The Suita study

“…However, patients in those studies by Pereira et al were young, and the present study is the first large‐scale study of patients in their 50s onwards with progression of chronic periodontitis. Numerous studies to date have shown that dental prosthetic treatment plays a major role in maintaining or improving masticatory performance (Palomares et al, 2018; Yamamoto & Shiga, 2018; Salazar et al, 2020). However, the present results indicate that not only maintenance and restoration of occlusion by prosthetic treatment but also maintenance of good periodontal status through periodontal treatment and self‐care has an important role to play in retaining masticatory performance.…”

Association between the dental occlusion and perceived ability to eat foods of Taiwanese older adults

“…A study by Wallace et al 23 indicated that adhesive bridgework effectively restored 10 occluding pairs of natural and replacement teeth in participants with shortened dental arches and that this procedure significantly improved their masticatory performance. Reconstruction of occlusal support enhances masticatory ability 23,24 ; however, the high cost of oral prostheses is a principal reason that some older adults opt not to undergo dental restoration, preferring instead to have their remaining teeth removed so that the government finances the complete cost of a set of dentures. This phenomenon explains why 1/10th of older adults in Taiwan are edentulous.…”

“…2,3,[16][17][18][19][20][21][22] Oral prostheses can improve masticatory function in older adults with tooth loss. 23,24 However, prosthetic restoration is expensive in Taiwan. Although dental treatment is generally covered under national health insurance, this does not include the cost of fixed or removable partial prostheses.…”
