Purpose: The purpose of this study was to estimate the influence of the inter-coronal freeway of lingualized occlusion on masticatory function.<BR>Methods: Two male and 4 female edentulous subjects were studied. The masticatory performance, masticatory movement, and subjective chewing sensation were studied using complete dentures that could be changed to 0.5, 1.0, 1.5and2.0mm of the inter-coronal freeway. The masticatory performance on chewing each test food of boiled fish-paste, peanuts, and raw carrot was measured, using the sieve method. The masticatory movement on chewing each test food of boiled fish-paste, peanuts, raw carrot and pickled Japanese radish was measured, using the MKG (Mandibular kinesiograph). The subjective chewing sensation of each test food of boiled fish-paste, peanuts, raw carrots, and pickled Japanese radish, and general foods in daily life, was evaluated by a visual analogue scale (VAS).<BR>Results: On 10, 20, and 30 repetitions of the chewing test of boiled fish-paste and peanuts, the masticatory performance was highest with 0.5mm of inter-coronal freeway. A higher inter-coronal freeway tended to have a slower closing time and cycle time. In the subjective chewing sensation of each test food and general foods in daily life, the values of a VAS were highest with 0.5mm of inter-coronal freeway.<BR>Conclusions: From these results, it was demonstrated that the masticatory function is most effective in 0.5mm of the inter-coronal freeway.
