Subjective and objective evaluation of masticatory function in patients with bimaxillary implant‐supported prostheses

Background People perform poorly in masticatory function tests despite well‐functioning prostheses. However, it is unclear whether there is an agreement between subjective and objective measures of mastication. Objectives To investigate the association between subjective and objective measures of masticatory function in patients with bimaxillary implant‐supported prostheses. Materials and Methods An experimental group (n = 25, age = 70.6 ± 7.5 years, eight women) with bimaxillary implant‐supported fixed prostheses and a control group (n = 25, age = 69.0 ± 5.3, 13 women) with natural dentition were recruited. The participants in the experimental group were included if they had been using the prosthesis for at least a year and had no obvious complaints with their prostheses. The control group was people with natural dentition and without any prostheses or complaints related to the masticatory system. The masticatory function was evaluated objectively with food comminution and mixing ability tests, and subjectively with jaw function limitation scale (JLFS) and oral health impact profile (OHIP). Results The experimental group performed poorly in both objective tests (p
