2. If the provisional restoration itself is too high, the results
may be those associated with:: trauma from occlusion
3. If the surfaces of a provisional restoration are
______________, the process of chewing will excessively
force food directly into the gingiva. An ___________
restoration may trap plaque by not allowing for any self-
cleansing or gingival stimulation from the chewing process.:
undercontoured; overcontoured
4. Which of the following provisional materials is limited to
intracoronal placement?: Provisional cement
5. Which of the following is the most durable of the pre-
formed crowns?: Stainless steel crown
6. A/An ___________________ provisional crown is crimped
and contoured at the contact and margins with crimping and
, contouring pliers.: stainless steel 7. Which of the following is
true of pre-formed polycarbonate provisional crowns?: The
primary advantage is their esthetics for replacement of anterior
teeth.
8. Pre-formed celluloid forms and polymer crowns are filled
with:: acrylic resins or composites
9. Why are one or two small holes usually placed in the
occlusal portion of the pre-formed celluloid or polymer crown
form?: To allow excess resin or composite material to flow out
when the crown form is seated
10. Which of the following is the most common choice of
matrix or template material for multi-unit and indirect
provisional techniques?: Vacuum-formed plastic
11. Which of the following is true of the direct technique for
provisional coverage?: A template of the tooth before preparation
