Maxillo-Mandibular Relationships Flashcards
____ is horizontal and reproducible; tissues at rest
Centric relation
The vertical occlusal dimension is about ____ mm
3mm
Physiologic resting position subtracted by interocclusal distance equals
Vertical dimension of occlusion
____ relationships include: occlusal vertical relations, rest vertical position
Vertical relationships
____ relationships include: centric relation (CR), protrusive, R and L lateral
Horizontal relationships
____ is defined as the distance between 2 points measured when the occluding members are in contact
Occlusal vertical dimension
_____ position is defined as a postural position the mandible assumes when all muscles that close the jaws and all muscle that open the jaws are in a state of minimal contraction sufficient only to maintain posture; no teeth are contacting
Physiologic rest position
____ is defined as the distance between 2 selected points measured when the mandible is in its physiologic rest position
Rest Vertical dimension
____ is defined as space between the teeth or occluding members when the mandible is in the physiologic rest position
Interocclusal distance
_______ = occlusal vertical dimension plus interocclusal distance
Rest vertical dimension
Is there one specific way to establish occlusal vertical dimension?
No
The following methods are used to establish _____; patient’s old dentures, swallowing threshold, closest speaking space, phonetics (“s” sounds), esthetics, tactile sense, paralleling posterior ridges, pre-existing records, facial measurements
occlusal vertical dimension
____ is the closest relationship of the occlusal surfaces and incisal edges of the mandibular teeth to the maxillary teeth during function and rapid speech
Closest speaking space
Which measurement should be greater: PRP or OVD?
PRP
____ is a horizontal mandibular position at an established vertical dimension; reproducible posterior hinge position of the mandible
Centric Relation
