Effect of occlusal splint thickness on electrical masticatory muscle activity during rest and clenching.

The extent of separation between the maxillary and mandibular teeth in the fabrication of interocclusal splints designed to achieve efficiency and muscle relaxation is controversial and undefined in the literature. Based on this premise, the aim of this study was to evaluate the effect of interocclusal splint thicknesses of 3 and 6 millimeters on the electrical activity of the anterior temporal...

[Control ability to coordination pattern of masticatory muscle activities during maximal clenching in centric occlusal position].

The control ability which changes the coordination pattern of masticatory muscles in the Maximal voluntary clenching was investigated in the correlativity, using the electromyogram and the Dental-Prescale system on ten normal subjects. Even the insignificant correlative Activity index to the balancing point of occlusal force was shown, though the anteroposterior control index (CA/P) marked slig...

Immediate Effect of Occlusal Errors on Masticatory Muscle Activity in Denture Wearers: A Pilot Study

Over the past three decades, little scientific progress has been made relative to occlusion in conventional complete dentures. Equal distribution of functional load throughout the residual denture foundation is likely an important factor in prosthesis stability and patient acceptance of dentures. A better understanding the relationship between denture occlusion and the physiologic behavior of m...

Influence of occlusal stabilization splint on the asymmetric activity of masticatory muscles in patients with temporomandibular dysfunction.

The aim of present study was to evaluate the symmetry of masticatory muscles' activity at various clenching levels in the intercuspal position in patients with functional disorders and in healthy subjects. The purpose was also to determine the effect of full-arch maxillary stabilization splint on the asymmetry of masticatory muscle activity in patients with temporomandibular dysfunction. In thi...

Medial pterygoid muscle activity during chewing and clenching.

Specific activity of the human medial pterygoid muscle in relation to jaw movements and occlusion during mastication and clenching tasks is unclear. EMG activity of the medial pterygoid, masseter, anterior, and posterior temporal muscles was recorded simultaneously with three dimensional incisor point movement of the mandible. Data were sampled and analyzed by an on-line computer system. Patter...
