e) VLC urethane dimethacrylate (Triad) Answer: Q: What materials
are used for provisional materials,
especially if the patient is allergic to PMMA?
◉ a) Crown/root ratio- optimal 2:3, minimum- 1:1
, b) Root configuration
c) Periodontal ligament area
d) No mobility Answer: Factors in evaluation of abutment tooth and
supporting tissues:
◉ a) RPD- 25 lbs
b) FPD- 50 lbs
c) Teeth- 150 lbs Answer: Opposing forces applied:
◉ The root surface area of the abutment teeth had to equal or
surpass that of the teeth being replaced with pontics. Used as a
clinical guideline.
The observation that the combined pericemental area of all
abutment teeth supporting a fixed dental prosthesis should be equal
to or greater in pericemental area than the tooth or teeth to be
replaced; as formulated for removable dental prosthodontics, the
combined pericemental area of the abutment teeth plus the mucosa
area of the denture base should be equal to or greater than the
pericemental area of the missing teeth. Answer: Ante's law: (Irwin H
Ante)
◉ a) Viscoelastic cushion
b) Sensory organ
c) Accommodates adaptive tooth movements
