Occlusal force, electromyographic activity of masticatory muscles and mandibular flexure of subjects with different facial types
OBJECTIVE The aim of this study was to evaluate whether vertical facial patterns influence maximal occlusal force (MOF), masticatory muscle electromyographic (EMG) activity, and medial mandibular flexure (MMF). MATERIAL AND METHODS Seventy-eight dentate subjects were divided into 3 groups by Ricketts's analysis: brachyfacial, mesofacial and dolychofacial. Maximum occlusal force in the molar r...
متن کاملEffect of jaw opening on masticatory muscle EMG-force characteristics.
This study was designed to evaluate the way in which changes in vertical jaw opening affected the relative contributions of various masticatory muscles to bite force production. EMG activity was recorded simultaneously from the masseter, and anterior, middle, and posterior temporalis muscles, during controlled isometric biting at different force levels and vertical jaw openings. EMG-force chara...
متن کاملThe influence of maxillary and mandibular osteoporosis on maximal bite force and thickness of masticatory muscles.
The aim of this study was to examine the bite force and masseter and temporal muscle thickness in individuals with maxillary and mandibular osteoporosis. 72 individuals were distributed into two equal groups: (1) facial osteoporosis and (2) healthy controls. Bite force on the right and left molar regions was recorded with a dynamometer and the highest value out of three measurements was recorde...
متن کاملMandibular residual ridge shape and the masticatory ability in complete denture wearers.
PURPOSE The purpose of this study was to investigate the influence of mandibular residual ridge shape on the masticatory ability in complete denture wearers. METHODS The subject group consisted of 199 complete denture wearers. The mandibular residual ridge of each subject was evaluated using a replica of the ridge which was obtained with heavy-body silicone impression material. The basal area...
متن کاملFacial dimensions, bite force and masticatory muscle thickness in preschool children with functional posterior crossbite.
Posterior crossbite may affect craniofacial growth and development. Thus, this study aimed to associate facial dimensions (by standardized frontal photographs) to masseter and anterior portion of the temporal muscle thickness (by ultrasonography) and maximal bilateral bite force in 49 children with deciduous and early mixed dentitions. They were distributed in four groups: deciduous-normal occl...
