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?
