Posterior mediotrusive contacts may interfere with the AG, thus preventing the disengagement of the posterior teeth during mandibular movements. Electromyographic studies show that the elevator muscles on the mediotrusive balancing side decrease in activity in the presence of a balancing contact, which supports the notion of a protective process.

Lateral rotation or laterotrusion (Right and left lateral movement). condyle ( opposite side) is called the non-working or mediotrusive or balancing condyle ( Fig. condyle balancing/orbiting path – Laterotrusion than protrusive path – Medial Mediotrusive Pathway Laterotrusive Pathway angle Mediotrusive Protrusion LATEROTRUSION. MEDIOTRUSION Mediotrusive dynamic contacts on both sides. Additionally mediotrusive and protrusive interferences on both sides.

The laterotrusive (working) and mediotrusive (non-working or balancing) sides reverse when the mandible moves in the opposite direction. Understanding tooth contacts that occur during the various movements is important in most aspects of Dentistry. Removing or lessening mediotrusive (balancing) interferences. Reducing excessive cusp steepness on the laterotrusion (working) contacts.

M.BUSH DepartmentofGeneralDentistry, Virginia Commonwealth University, Richmond, Virginia 23298 The Angle classification ofocclusion, as well as occlusal contacts determined at retrusion, mediotrusion, laterotrusion, and pro- trusion were recorded from 298 dental students.

The maximum possible mediotrusion score for the posterior dentition was 2 premolar and 2 molar zones X 1 facet location X maximum sever- … They were also divided into protrusive laterotrusion (PL) or retrusive laterotrusion (RL) groups according to the tracing patterns. The incidence of clicking was 23·8% in all 84 TMJs. There was no significant difference between the M and the D groups. However, clicking occurrence was significantly higher in the RL than in the PL group (P<0·05). laterotrusion: ( lat'ĕr-ō-trū'zhŭn ), The outward thrust given by the muscles of mastication to the rotating mandibular condyle during movement of the mandible.

In 2006, Onodera et al, in a sample of 86 subjects with and without temporomandibular joint (TMJ) symptoms, and with the help of Bruxchecker®, reported that the dental wear patterns in SB that were most frequently presented in laterotrusion were the incisor-canine-premolar (ICP: 38.9%) with mediotrusive wear or balanced areas (63.9%) in Posterior mediotrusive contacts may interfere with the AG, thus preventing the disengagement of the posterior teeth during mandibular movements. Electromyographic studies show that the elevator muscles on the mediotrusive balancing side decrease in activity in the presence of a balancing contact, which supports the notion of a protective process.

Desde el punto de vista fisiopatológico, se produce un movimiento condilar anómalo con estiramiento y afectación de los tejidos blandos del lado de no trabajo y desvia-ción de la mandíbula que puede traumatizar la arti-culación16. The subjects were divided into M and D groups according to their mesial and distal canine guidance, and were also divided into protrusive laterotrusion (PL) and retrusive laterotrusion (RL) groups according to their laterotrusive tracing patterns.
