This study compares a new technique (Dental Prescale System) using pressure-sensitive foils for recording of maximal jaw closing force with a conventional clinical measurement using a miniature force transducer in 17 students. For assessment of load distribution the "pressure" image was superimposed on digitiZed images of dental casts and compared with(More)
The aim of this study was to investigate the bite force and its distribution over the maxillary dentition in completely dentate subjects. Twenty-three dental students (14 Danish, 9 Japanese) with complete dentitions, but without occlusal contact on the third molars participated and their maximal bite forces were measured using the Dental Prescale System(More)
PURPOSE The purpose of this study was to clarify the influence of changes of occlusal contacts on adjacent tooth displacement during articulation. MATERIALS AND METHODS The amount and direction of displacement of the maxillary left first molar and adjacent teeth were measured using a displacement transducer, Type M-3. Seven subjects were included in this(More)
This study describes a new method to apply bite force measurement as an objective evaluation prosthodontic treatment. The occlusal load centre, i.e. the centre of balance of distributed occlusal force on the dentition is used as an index of bite force. The digitised image of the occlusal load centre was superimposed on the digitised image of a standardised(More)
We have reported that the analysis of the maximal bite force distribution over dentition was available for objective evaluation of prosthodontic treatment. The purpose of this study was to investigate the reproducibility of occlusal force distribution in maximal voluntary clenching. The maximal bite forces of 10 normal subjects with complete dentition were(More)
The aim of this study is to clarify the normal relationship between jaw elevator muscle activity and occlusal contact in lateral positions in order to assess the appropriate anterior guidance of lateral jaw movements for occlusal reconstruction and treatment. The EMG-activity of the right and left masseter, anterior temporal, and posterior temporal muscles(More)
a) Angle of frontal and horizontal inclination b) position c) numbers and d) area of the contact points at several lateral occlusions which have different distances from the intercuspal position (ICP) were examined on 12 normal subjects to suggest the normal form of lateral occlusion. Each lateral contact point was different due to the LED jaw tracing(More)
14 natural dentitioned subjects with no signs of TMJ disorders, aged 19-58, were used in this study. They were divided into three groups according to their occlusal guidance. One is canine guidance group (CG group), the other is group function group (GF group), and the last is group having non-working side contacts (FB group). All subjects were asked to(More)
