Laterotrusive movements were of equal length and similar to the length of protrusion. Twenty-six patients with muscle pain, in many instances, demonstrated asymmetry in the length of laterotrusive movements. Different pathways for moving the mandible away from the intercuspal position and returning to this position could be seen during laterotrusion.


This protrusion stabilises laterotrusion of the condyle and the disk against the articular tubercle in order to spread the masticatory pressure! Dynamics of the temporomandibular joint (TMJ) The maximum isometric contraction force (adductory component) of all jaw-closing muscles is approximately 150 kg.

stated by Rabie et al. in 2002. Laterotrusion and laterognathia need to be differentiated in the patient (if present) at the time of recording of postural rest position. Laterotrusion is manageable through functional appliances while laterognathia is not.

Figure 7-38 illustrates the direction of movement of the masticatory muscles. The functional motions permitted are mandibular depression (mouth opening), mandibular elevation (mouth closing), protrusion (anterior translation; Fig. 13.3) and retrusion (posterior translation; Fig. 13.4), and right and left lateral excursion or laterotrusion (lateral deviation; Fig. 13.5). Maximal contact of the teeth in mouth closing is Additionally, Ingervall18 found no differences in maximum laterotrusion between 10-year-old girls and women aged 20 years, suggesting that in girls, the range of movement of the mandible reaches adult level by 10 years of age. In this study, we found a significant difference in laterotrusion between the children's group and the adult group. mandible (also a rotational axis), whereas the swinging condyle on the right balance side swings forward and inward in a translational movement.

The outward thrust given by the muscles of chewing to the condyle during movement of the mandible. The relation of mandibular laterotrusion with ipsilateral TMJ clicking.

Laterotrusion of mandible

of the mandible in the horizontal plane Protrusion With protrusion, the mandible moves forward. There is ventral and caudal movement of the two condyles. The movement tracks of the maxillary tooth are shown on the mandibular tooth. Mediotrusion and laterotrusion In lateral occlusion, a differentiation is made between laterotrusion on the working

Abstract During movements of the mandible and cervical spine the auriculotemporal nerve and its branches must adjust to the changed surrounding structures in order to maintain functional capability. mandible; laterotrusion, side thrust laterally or outward; lateroprotrusion, outward and forward thrust; lateroresurtrusion, outward, backward, and upward thrust; and mediotrusion, side thrust medially or inward, downward and forward thrust of the nonworking condyle (see Fig 1). Example 1: Maxillary Molar Materials and methods: The sample was comprised of 92 healthy children (7.2-10.6 years old) and 40 adult controls (18-34.7 years old). Examinations included the maximal mouth opening capacity and laterotrusion to the right and to the left. The condylar path inclination angle was calculated at 3 mm and 5 mm protrusion of the mandible. High risks of sustaining malocclusion are preceded by the fracture of nasal bone (OR = 3.067), mandible, condylar neck/base, control the protrusion and laterotrusion of the mandible.

Laterotrusion of mandible

Lateral movement of the mandible is unique owing to the fact that both the condyles do not share the same path. The working condyle rotates at the terminal h The laterotrusion of the mandible is often combined with the clicking of the temporomandibular joint. An optoelectronic measuring method renders it possible to exactly record the clicking and the position of the mandible at this moment. With this method 25 patients with an initial clicking were observed. The outward thrust given by the muscles of chewing to the condyle during movement of the mandible.

the condyle to make a mediotrusive movement, thereby enabling a lateral movement of the mandible on the opposite side 3. The condyle to make a laterotrusive movement, thereby enabling a lateral movement on the same side 4. The condyle to move forward from the articular fossa The mandible is the largest and strongest bone of the face. It creates our lower jaw and holds the lower teeth 🦷. The bone articulates with the temporal bone to form the temporomandibular joint, allowing us to talk, eat, and yawn 😀.

Kinuta et al. [13] used a digital camcorder, a mirror for anteroposterior movement detection summary It has been accepted that the shape of the mandibular base, and especially the gonial angle of the mandible, correlates with the function of the jaw closing muscles. The gonial angles of the mandible and condylar and ramus heights of 30 complete denture wearers (18 women, 12 men, mean age 61 years, range 42–74 years) coming for renewal of their dentures were measured using panoramic 2008-12-20 2012-09-23 Selections from chapter 9: Oral Cavity & Perioral Regions from the Head and Neck Anatomy for Dental Medicine Virtual planning and guided reconstruction of the mandible following ablative surgery have become standard procedures in reconstructive surgery.

The name of the joint is derived from the two bones which form the joint: the upper temporal bone which is part of the cranium, and the lower jawbone or mandible The six components of the TMJ are the (1) the Mandibular condyles, (2) the Articular surface of the temporal bone, (3) the joint Capsule, (4) the Articular disc, (5) the Ligaments and (6) the Lateral pterygoid.

Features of the mandible. Two main parts make up the mandible: The horizontal body ; Two vertical rami This video provides a brief overview of the mandible.Bone: mandibleStructures: body, ramus, mandibular angle, mandibular condyle, mandibular notch, mental fo Lucent lesions of the mandible are not uncommon and may be the result of odontogenic or non-odontogenic processes. Lucency may be conferred by a cystic process (e.g. periapical cyst) or a lytic process (e.g.
