What is lateral excursion?
Lateral excursion is the second key step when we chew our food. Once the mouth opens and the food enters the oral cavity, the jaw moves sideways and grinds the food, closes gradually and finally the teeth meet each other before the mouth comes back in a state of rest. Lateral excursion might be hampered due to problems in the gnathic system.
Dynamic occlusion: lateral excursion
Dynamic occlusion: lateral excursion The dynamic occlusion is the contact that teeth make during movements of the mandible - when the jaw moves side to side, forward, backward or at an angle. In dynamic occlusion, the contacts of the teeth are not points as in static occlusion, but they are described with lines. ...

Dental Occlusion
Lateral excursion. Lateral excursions are a form of dynamic occlusion which occurs when the mandible moves left or right with teeth in contact. They can be described as: Canine guidance: canine protected articulation. The canines on the working side are the only occluding teeth whilst all other teeth become discluded when carrying out lateral ...
Range of Motion: Temporomandibular (TMJ) Lateral Excursion
Learn the proper technique to measure lateral excursion range of motion for the temporomandibular (TMJ) joint using a ruler.
Occlusion Static Occlusion, Dynamic Occlusion and Guidance
Canine Guidance If you slide you teeth to your right, and only your right canines contact during this lateral excursion, then you have canine guidance. This is reckoned to be a good thing, as canines are excellent at coping with lateral forces. If this happens, you are said to have a canine-protected occlusion.
Introduction to Occlusion
Canine guidance - this means during lateral excursion of the mandible the canines are the teeth which guide the mandibles movement and the last to disclude ; Group function - this means during lateral excursion of the mandible, the tooth contact which guides the movement is shared between multiple teeth on the working side.
6: OCCLUSION
The teeth on the right should not be contacting or not working (Figure 6.1.3), which is why this side is termed the non-working side. ... In these lateral excursions, only the canines contact and take the occlusal load, while the other teeth are separated. The canines are better suited than the posterior teeth to distribute these sideways ...

The temporomandibular joint (TMJ), pain, and how to fix it
The lateral excursion is the movement to the left and right of the zero position of the jaw. The medial excursion is the movement back to the zero position of the jaw (Saladin, pg. 291). ... This can be brought on by teeth grinding, excessive chewing (think gum), or chewing of harder food. There are many different treatment options for a person ...

Functional Occlusal Patterns and Their Relationship to Static Occlusion
There are three main concepts regarding tooth contact during the lateral excursion of mandibular movement: (1) balanced occlusion, which was developed from the work of Bonwill, 3 (2) canine guidance, described by D'Amico, 4 and (3) group function, as discussed by Beyron. 5. The relationship between static and dynamic occlusion is one of the ...
What Is Occlusion?
Group Function. In this type of anterior guidance, the contacts are shared between several teeth on the working side during a lateral excursion. To qualify for the term 'group function', the contacts within the group that are towards the front of the mouth should be the earliest and/or hardest contacts.
TMJ Movements
TMJ Movements. Normal movements of the jaw during function, such as chewing, are known as excursions. There are two lateral excursions ( left and right ) and the forward excursion, known as protrusion, the reversal of which is retrusion. When the jaw is moved into protrusion, the lower incisors or front teeth are moved so that they first come ...

Occlusion and malocclusion
• An immediate and permanent posterior disclusion in lateral and protrusive contact with no associated non-working side interferences (tooth contacts); this is achieved by the presence of canine guidance or group function in lateral excursion and incisal guidance in protrusion. Thus, the anterior teeth protect the posteriors;
Effect of Lateral Excursive Movements on the Progression of Abfraction
The current study primarily investigated the hypothesis that reducing excursive occlusal loads on a tooth in lateral excursion would lead to a reduction in the rate of progression of abfraction lesions. The study was carried out in a primary care setting, in this case, a predominantly private general dental practice, with most of the subjects ...
Lingualized occlusion revisited

A Clinical Study to Determine the Pattern of Occlusal Contacts in
Group function is a contact pattern on two or more working side teeth throughout lateral excursion. The only problem with these definitions is the absence of a description for the position of mandible.

Occlusal contact area of mandibular teeth during lateral excursion
Results: At the intercuspal position, estimated occlusal contact areas of the first and second mandibular molars were on average 12.6 mm2 and 9.0 mm2, respectively. However, after 3.0 mm of lateral excursion, their areas were sharply reduced to 2.2 mm2 and 1.5 mm2 on the working side, and 0.4 mm2 and 1.1 mm2 on the nonworking side, respectively.
Pattern of Occlusal Contacts in Eccentric Mandibular Positions in
Only the red marks on teeth were considered to indicate occlusal contact. To prevent movement with mandibular opening or movement without occlusal contact and lateral-protrusive excursion, the movement was observed closely, and occasionally the subject was instructed to correct the movement.
