This can occur during phases of rapid structural loss on the functional surfaces of
teeth Correct Answer: Compensatory eruption or alveolar extrusion
True or false, only the dental complex erupts to compensate for progressive loss
of vertical dimension in compensatory eruption Correct Answer: False
The dento-alveolar complex erupts to compensate
True or false, compensatory eruption/alveolar extrusion does not occur in
segments, it occurs along the entire arch Correct Answer: False
It can also occur in segments
True or false, if you have segmental compensatory eruption/alveolar extrusion,
the facial gingival margins of the teeth will not move in a coronal direction Correct
Answer: False
They will be positioned more occlusal/incisal along with the eruption
What is a tongue pillow? Correct Answer: When the tongue occupies the new
inter-occlusal space that develops after loss of tooth structure
What is a cheek pillow? Correct Answer: When the cheek occupies the new inter-
occlusal space that develops after loss of tooth structure
True or false, altered passive eruption and compensatory eruption are the same
thing Correct Answer: False
This is failure of the dento-gingival complex to migrate apically and gives the
appearance of short clinical crowns Correct Answer: Altered passive eruption
True or false, altered passive eruption is not usually associated with wear or loss
of tooth structure Correct Answer: True
, True or false, attrition can eliminate excursive interferences Correct Answer:
False
Severe attrition can only occur if the upper teeth are.... Correct Answer: in the
way of the lower teeth during mandibular movement
True or false, teeth cannot wear if they cannot touch Correct Answer: True
True or false, even with stable anterior guidance, posterior teeth still can
experience attrition? Correct Answer: False
True or false, physiologic tooth wear occurs on the incisal, occlusal, inter
proximal, facial, and lingual surfaces of teeth Correct Answer: False
Only the incisal, occlusal, and inter proximal surfaces
What is the pre-requisite to any definitive treatment for pathologic tooth wear?
Correct Answer: Accurate determination of the etiology
What are the 4 main possible etiology of tooth wear? Correct Answer:
Neuromuscular
Drug-induced
Structural
Dietary
Of the 4 main etiologies of tooth wear, what are the ones we have no control
over? Correct Answer: Neuromuscular
Drug-induced
What are the 2 main classes of drugs that cause drug-induced bruxism? Correct
Answer: Benzodiazepines - anti-anxiety - valium, xanax, ativan
Phenothiazines - anti-psychotic - end in -zine or -zin
Where teeth ___ determines how they will ___ Correct Answer: touch; wear
What are the determinants of occlusion? Correct Answer: Condylar inclination
