The Impact of Occlusal Support Patterns in Right-Handed Denture Wearers on Oral Function and Oral Health-Related Quality of Life
Background
Denture treatment for unilateral distal extension defects can cause organic and functional asymmetry in the oral cavity, which may be influenced by physical laterality and the preferred chewing side (PCS). However, existing classification systems for dental defects overlook left–right defect distribution, and individual laterality is rarely considered in treatment planning.
Objective
This study investigated the relationship between dental defect location and laterality.
Methods
This was a cross-sectional study of 176 right-handed elderly participants divided into five groups by denture type: control (n = 87), right distal extension (n = 9), left distal extension (n = 13), bilateral distal extension (n = 43), and complete denture (n = 24). Primary outcomes included masticatory efficiency, bite force, oral health-related quality of life (OHRQoL), and PCS assessed through interviews.
Results
The right distal extension group demonstrated significantly reduced masticatory efficiency, bite force and OHRQoL compared to the control group, indicating diminished oral function and quality of life. The left distal extension group showed significant left–right differences in function, with reduced performance on the distal extension defect side. The right side was the PCS in all groups, with no significant differences in distribution observed between the control and denture groups.
Conclusion
In elderly individuals with unilateral distal extension dentures, right-handed individuals demonstrate different masticatory functions based on whether the defect is on the right or left side. Additionally, when occlusal support is bilaterally maintained through prosthodontic treatment, including dentures, the impact of structural asymmetry on the PCS is limited.
期刊介绍：
Journal of Oral Rehabilitation aims to be the most prestigious journal of dental research within all aspects of oral rehabilitation and applied oral physiology. It covers all diagnostic and clinical management aspects necessary to re-establish a subjective and objective harmonious oral function.
Oral rehabilitation may become necessary as a result of developmental or acquired disturbances in the orofacial region, orofacial traumas, or a variety of dental and oral diseases (primarily dental caries and periodontal diseases) and orofacial pain conditions. As such, oral rehabilitation in the twenty-first century is a matter of skilful diagnosis and minimal, appropriate intervention, the nature of which is intimately linked to a profound knowledge of oral physiology, oral biology, and dental and oral pathology.
The scientific content of the journal therefore strives to reflect the best of evidence-based clinical dentistry. Modern clinical management should be based on solid scientific evidence gathered about diagnostic procedures and the properties and efficacy of the chosen intervention (e.g. material science, biological, toxicological, pharmacological or psychological aspects). The content of the journal also reflects documentation of the possible side-effects of rehabilitation, and includes prognostic perspectives of the treatment modalities chosen.
