 This study found that implant supported denture wearers exhibited different masticatory movements and performances depending on whether they chewed on their habitual or non-habitual chewing side. On the habitual chewing side, the masticatory movement was more forceful, resulting in greater opening distances and wider masticatory widths. Additionally, the cycle times were shorter and the masticatory performance was higher than on the non-habitual chewing side. These findings suggest that implant-supported dentures may be better suited for habitual chewers who prefer to chew on one side over the other.
