UNLABELLED The inferior head of lateral pterygoid (IHLP) is thought to play a critical role in the generation and control of lateral jaw movements. AIM The aim was to test the hypothesis that a change to the lateral tooth guidance (working-side occlusal alteration, OA) results in a significant change in the electromyographic (EMG) activity of the IHLP during standardised lateral jaw movements (laterotrusion) tracked by a jaw-tracking system. METHODS Ten trials of right laterotrusion were… Expand
The Lateral Pterygoid Muscle: Function and Dysfunction
The lack of studies of these issues means that there is no definitive evidence in humans for the "lateral pterygoid hypothesis," and there is also little reliable information as to the effect of occlusal variables on the activity of the lateral pteryGoid muscle. Expand
Influence of Occlusal Interference on the Mandibular Condylar Position.
Occlusal interference leads to immediate change of the condylar position within the temporomandibular joint, and average values of determined superior condylars position confirm occurrence of lever within dental arches. Expand
The difficult relationship between occlusal interferences and temporomandibular disorder - insights from animal and human experimental studies.
Individual differences in vulnerability to occlusal interferences do exist, and psychological factors appear meaningful for symptomatic responses to artificial interferences in subjects with a history of TMD. Expand
The difficult relationship between occlusal interferences and temporomandibular disorder – insights from animal and human experimental studies
The aetiology of temporomandibular disorder (TMD) is multifactorial, and numerous studies have addressed that occlusion may be of great importance. However, whether occlusion plays a crucial role inExpand
Effect of facet inclination and location on TMJ loading during bruxism: An in-silico study
Abstract Introduction Functional impairment of the masticatory region can have significant consequences that range from a loss of quality of life to severe health issues. Increased temporomandibularExpand
Injury responses of Sprague-Dawley rat jaw muscles to an experimental unilateral anterior crossbite prosthesis.
UAC causes injury and very limited inflammatory and fibrosis adaption in the masseter and LPM and alterations were partially recovered by the cessation of dental stimulation at an early stage. Expand
An Objective Registration Method for Mandible Alignment
This chapter introduces a computer-controlled method for mandible alignment using the DIR®System, a final method of measurement which gives objective, reproducible and documentable results. Expand
A Comparative Study to Evaluate the Occlusal Contacts among the Tribal and Urban Population during Lateral Eccentric Mandibular Movements
The canine protected occlusal scheme seems to be more suitable for Orthodontic and Prosthodontic rehabilitation planned in younger patients, while the Group function occlusion may be a suitable pattern for middle age and older patients, especially for people with coarse dietary habits. Expand

Ipsilateral interferences and working-side condylar movements.
A working-side interference has an immediate, significant effect on working- side condylar movement. Expand
Activity of inferior head of human lateral pterygoid muscle during standardized lateral jaw movements.
The data suggest that the IHLP is one of the principal jaw muscles involved in a lateral jaw movement with the teeth together while the other jaw muscles may play a contributory or facilitatory role. Expand
The role of the inferior head of the human lateral pterygoid muscle in the generation and control of horizontal mandibular force.
It is suggested that the IHLP is important in the generation and fine control of contralaterally directed, horizontal jaw forces. Expand
The effect of posterior tooth guidance on non-working side arbitrary condylar point movement.
The data suggest that, for the same magnitude of mandibular displacement during lateral excursion, the introduction of a posterior tooth guidance limits condylar displacement on the non-working side. Expand
Relationship between occlusal contacts and jaw-closing muscle activity during tooth clenching: Part II.
Electromyographic recordings used to study the effects of changing the location, size, and direction of effort on specific contact points during maximal clenching tasks in human subjects confirm their specific associations with the activity of muscle groups. Expand
Activity in the inferior head of the human lateral pterygoid muscle with different directions of isometric force.
The data suggest that the inferior head of the human lateral pterygoid is involved in the creation and fine control of mandibular forces in different horizontal directions. Expand
Influence of experimental occlusal discrepancy on masticatory muscle activity during clenching.
Clenching on the experimental interferences resulted in distinct patterns in the jaw elevator muscles, and the most characteristic change was observed when clenching effort was exerted on theimental non-working side interference. Expand
The influence of altered working-side occlusal guidance on masticatory muscles and related jaw movement.
It is suggested that non-working side contacts dramatically alter the distribution of muscle activity during parafunctional clenching, and that this redistribution may affect the nature of reaction forces at the temporomandibular joints. Expand
Immediate effect of occlusal contact pattern in lateral jaw position on the EMG activity in jaw-elevator muscles in humans.
Clenching in a lateral mandibular position under natural conditions induced an activity pattern with a clear dominance of the anterior and posterior temporalis muscles on the working side, suggesting that the nonworking-side occlusal contacts have a significant effect on clenching-induced temporalis muscle activity. Expand
Effect of altered canine guidance on condylar movement during laterotrusion.
The results of this study suggest that there is a relationship between the steepness of canine guidance and the pattern of the working-side condylar movement. Expand
