What does the face bow do?

6mm
What is the 3rd point of reference on the DENAR facebow?
43mm from incisal edge
The bite-fork of the facebow should go on what structure of the face?
the MIDLINE
CLINIC: What do we do AFTER recording the facebow?
get the VDR and VDO!!
________: is in an upright position and the involved muscles, particularly the elevator and depressor groups, are in equilibrium in tonic contraction, and the condyles are in a neutral, unstrained position

Closest Speaking Space…1-2mm
VDR - _____ = Freeway Space (__-__mm)
VDR - VDO = Freeway Space (2-3mm)
Clicking of the teeth is a result of ________ inter-occlusal space.
INADEQUATE
Facial distortion, tense strained appearance are results of ________ inter-occlusal space.
INADEQUATE
Difficulty closing lips and difficultly swallowing are results of _______ inter-occlusal space.
INADEQUATE
BOTH soreness and discomfort under the denture AND increased ridge resorption due to trauma are results of _______ inter-occlusal space.
INADEQUATE
INADEQUATE INTER-OCCLUSAL REST SPACE = EXCESSIVE _____
VDO
overclosure is potentially damaging to the ____ and is a result ______ inter-occlusal rest space.
TMJ….EXCESSIVE
With EXCESSIVE interocclusal rest space the Pt will have _______ inter arch distance when the teeth are in occlusion.
REDUCED
When normal tongue space is limited, it is most likely a result of _______ interocclusal space
EXCESSIVE
Excessive Interocclusal Rest Space= Inadequate ____
VDO
angular _______ is sometimes attributed to overclosure and therefore _______ interocclusal rest space
cheilitis…Excessive
with excessive interocclusal rest space muscles of facial expression lose their ______
TONE
Centric Relation is a when the condyles are in their most ______ and ______ position in the articular eminences.
ANTERIOR AND SUPERIOR
The key with a CR record is that it is a ________ positon
repeatable
in a complete denture the goal is to have CR = ____ = MIP
CO (centric occlusion)
What two things must the clinician do when taking the CR?
1.hold the mand plate in place 2. Pt tongue to back of mouth
The maxillary incisors contact the _______ of the lower lip during speech production of f and v sounds.
wet-dry line
When setting the max ant teeth, they should be __-__ mm from the center of the incisive papilla
5-7mm
if the lips are not supported properly by the teeth _______
sounds may be defective: “__,__”
labial…“p,b”
_________ are produced by contact between the maxillary incisors
and the wet-dry line of the lower lip
labiodental…“f,v”
_______ are made by contact between the tip of the tongue and the palate at the rugae area with a small space for the escape of air
linguopalatal..”s,sh”
