15 Questions
What does the term 'Jaw Relations' refer to?
Any spatial relationship of the maxilla to the mandible
What maintains the vertical dimension (VD) according to the text?
Occlusion of the teeth or balanced tonic contraction of opening and closing muscles
What are the two important guides for deciding vertical relation mentioned in the text?
Vertical dimension of rest or physiologic rest position (VDR) and Vertical dimension of occlusion (VDO)
What happens if the vertical dimension (VD) is not measured accurately?
The joint will be strained
What is referred to as 'Vertical dimension of rest or physiologic rest position' according to the text?
Vertical separation of the jaws when opening and closing muscles are in minimal tonic contraction
What is responsible for maintaining vertical dimension (VD) as per the text?
Tooth acting as a vertical stop
What does altering the Vertical Dimension (VD) lead to, according to the text?
Severe discomfort in both TMJ and muscles of mastication occurs
What is related to patient's esthetical appearance according to the text?
Vertical dimension (VD)
What does 'Vertical dimension of occlusion' refer to as mentioned in the text?
The length maintained by occlusion or musculature
What is responsible for maintaining posture according to the text?
Vertical separation maintained by opening and closing muscles
What is the physiologic rest position of the mandible?
Position when the head is upright, muscles are in tonic contraction, and condyles are in a neutral unstrained position
What is the purpose of recording centric relation?
It is a bone to bone relation and serves as a reliable guide for developing centric occlusion in complete dentures
What happens with an increase in vertical dimension of occlusion (VDO)?
Chin-nose distance increases and patients may have an appearance of open mouth
What is the interocclusal distance (IOD) frequently referred to as?
"Free way space"
What is centric relation?
The most retruded relation of the mandible to the maxilla when the condyles are in the most posterior unrestrained position
