The tooth to be restored.
By protecting teeth, cheek, and tongue.
When two or more teeth contact on the working side during lateral excursion, ideally involving premolars and canines.
When ensuring appropriate guidance with new restorations, increasing vertical dimension, removing occlusal interferences, or providing an occlusal stabilization appliance.
Contacts in retruded contact position (RCP).
When the occlusal scheme is redesigned in the retruded contact position (RCP) when an ICP cannot be reliably established.
In Class II div 2, upper central incisors are retroclined and overjet is minimal or increased.
The final record should not have any perforations.
To leave the occlusion as it was found, avoiding high restorations.
In ICP (Intercuspal Position) or CR (Centric Relation).
The Michigan splint.
Arc of closure of the mandible with the condyles rotating about the terminal hinge axis.
Cusps that do not occlude with the opposing teeth, usually buccal on upper and lingual on lower.
With or lie immediately below the cingulum plateau.
Various masticatory system disorders.
It defines the range of mandibular movements.
A terminal hinge axis position where condyles articulate with the thinnest, most avascular part of their respective discs.
The direction and magnitude of the slide.
Aid diagnosis of TMJ dysfunction.
Tooth fracture, restoration fracture/failure, tooth movement/drifting, tooth mobility, TMJ/myofacial pain, and dental pain.
Full translation of the condyle over the articular eminence with no teeth in contact.
Axis of rotation of the condyles during the first few millimeters of mandibular opening.
Occlusal surfaces that meet in ICP, usually cusp tips and marginal ridges.
To identify which teeth require adjustment or restoration as part of the treatment plan.
They are the most important tool when mounted on a semi-adjustable articulator.
Static occlusion and dynamic occlusion.
Vaseline.
It may modify the slide, putting stress on the TMJ and changing the IDC.
It could lead to a tooth that was previously not under load becoming stressed.
When there are sufficient teeth and ICP is stable.
