ing from three nerves from the mandibular division of the trigeminal nerve (CN mandible moves in laterotrusion on the working side and in medio- trusion on Mar 14, 2018 maximum mandibular opening decreases 60% -70% immediately after orthognathic surgery (OS) and other variables, including laterotrusion, Deflective Occlusal Contacts. 5. Mandibular Deflection: Right___ Canine Guidance – Laterotrusion. 3. Group Function– Laterotrusion.
The results indicate that the movements of the working side condyle were affected functionally by the laterotrusion, but not by either the mesial or the distal type of canine guidance. are shown on the mandibular tooth. Mediotrusion and laterotrusion In lateral occlusion, a differentiation is made between laterotrusion on the working side and mediotrusion on the non-working side. The connection between the beginning and end point of the condyle moved inwards on the mediotrusive path forms the Bennett 2021-02-28 · Ipsilateral laterotrusion improved from 4.3 mm before operation to 7.9 mm after operation (p < 0.05), while maximum mandibular protrusion changed from 2.8 mm to 7.4 mm (p < 0.05). Twelve months after surgery, all bony fragments healed normally, and no severe bone resorption occurred according to the postoperative CT examination. The mandibular advancement is either done in single advancement or stepwise. Single advancement more than 5mm causes unnecessary strain as stated by Rabie et al.
Yellow arrow indicates In particular, during maximum jaw laterotrusion, lower incisor movement strongly reflected condylar movement, and the influence of craniofacial morphology on mandibular border movement was minimal.

The purpose of this study was to investigate the association of temporomandibular joint (TMJ) clicking with the types of canine guidance, the tracing patterns of mandibular laterotrusion and, espec 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.

[L. lateralis, to the side, + L. trudo, pp. trusus, to thrust] Medical Dictionary for the Health Professions and Nursing © Farlex 2012 In a young subject group, the movements of left and right mandibular laterotrusion were measured at the incisal and the lateral pole point of the working side condyle. All samples were divided into one of two groups according to the mesial (M) or distal (D) canine guidance. 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.

Based on the distribution of the measurements in the population (lowest decentile), the mandibular mobility of subjects with a maximum opening of < 43 mm and laterotrusive movements < 8 mm or protrusive movements < 5 mm might be considered as being limited. However, these limitations do not necessarily require treatment. In particular, during maximum jaw laterotrusion, lower incisor movement strongly reflected condylar movement, and the influence of craniofacial morphology on mandibular border movement was minimal. Therefore, lower incisor movement during maximum jaw laterotrusion appears suitable to evaluate condylar movement. 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).

Protrusion = Mandibula bewegt sich translatorisch ventral. The 3D articulated system with spherical head is simply printed with the models of the upper and lower jaw to precisely simulate physiological mandibular movements (protrusion, mediotrusion and laterotrusion).
