    Bite force in patients with functional disturbances of the masticatory system.

    Journal of oral rehabilitation·2012

    Complete dentures offer limited improvement in oral function for edentulous individuals. Even with new dentures, bite force remains significantly lower than in natural teeth wearers, highlighting functional handicaps.

    Area of Science:

    • Dentistry
    • Prosthodontics
    • Oral Health

    Background:

    • Complete denture wearers often experience reduced oral function compared to individuals with natural teeth.
    • Assessing the efficacy of complete dentures in restoring masticatory function is crucial for improving patient quality of life.

    Purpose of the Study:

    • To evaluate and compare oral function in complete denture wearers with satisfactory and unsatisfactory dentures.
    • To assess changes in oral function after replacement of dentures.
    • To compare the bite force of denture wearers with that of dentate individuals.

    Main Methods:

    • Utilized questionnaires, clinical examinations, and bite force measurements to assess oral function.
    • Studied two groups of complete denture wearers: one with satisfactory dentures (n=10) and one with unsatisfactory dentures (n=10).

  • Re-examined six patients from the unsatisfactory group after 1 year of wearing new dentures and compared results with ten dentate controls.

    • Main Results:

    • No significant difference in bite force was observed between satisfactory and unsatisfactory denture groups.
    • Patients reported improved chewing sensation with new dentures, but bite force measurements did not show significant increases.
    • Maximal bite force in dentate subjects was 5-6 times greater than in complete denture wearers.

    Conclusions:

    • Complete dentures, even when clinically satisfactory, provide a poor substitute for natural teeth regarding masticatory function.
    • Edentulous individuals face significant handicaps in oral function, which are not fully overcome by current complete denture technology.
