QUESTIONS SET A+
✔✔Dental caries has destroyed a cusp on a mandibular molar. The dentist doesn't want
to crown the tooth. What alternative prosthesis might be employed? - ✔✔An onlay
✔✔A sports injury has damaged a maxillary central incisor and left it fractured and
darkened. What type of crown might be employed? - ✔✔An all-ceramic crown
✔✔Tooth #18 (mandibular left second molar) is badly decayed and requires a crown.
The patient bruxes and is unconcerned about esthetics. What type of crown might be
employed? - ✔✔A cast-metal crown
✔✔When expense is not an issue, the fixed partial denture, more commonly called a
____________, is preferred. - ✔✔bridge
✔✔Each tooth that is part of the prosthesis is called a ______________. - ✔✔unit
✔✔A three-unit bridge would include how many teeth? - ✔✔Three
✔✔Pontic - ✔✔Artificial tooth that replaces a missing natural tooth.
✔✔Resin-bonded bridge - ✔✔Fixed dental prosthesis with wings that are bonded to the
lingual surfaces of adjacent teeth; also known as Maryland bridge
✔✔____________-______________ ____________ was introduced in the 1970s as a
way to replace missing teeth without stripping healthy adjacent teeth of all of their
enamel. Rather than the standard crown preparation for the abutments, a minimal
preparation was performed such that wings on either side of the pontic could be bonded
to etched enamel on the abutments. - ✔✔resin-bonded bridge
✔✔Retraction cord - ✔✔This material is tucked into the gingival sulcus to retract the
gingival margin so that a complete impression can be made of the prepared tooth.
, ✔✔Cord-Packing instrument - ✔✔This instrument resembles a plastic instrument and is
used to tuck retraction cord into the sulcus.
✔✔Electrosurgery unit - ✔✔This instrument resembles a plastic instrument and is used
to tuck retraction cord into the sulcus.
✔✔True or False: An abutment is a tooth (or teeth) located adjacent to a missing tooth
that is used to support a prosthesis. - ✔✔True
✔✔True or False: Retraction of the gingiva is important so that the margin of the crown
preparation can be captured in the final impression. - ✔✔True
✔✔True or False: Onlays can be cast from metal or made from a ceramic material such
as porcelain. - ✔✔True
✔✔True or False: A resin-bonded bridge requires the removal of more tooth from the
abutment, which is why dentists resist using them. - ✔✔False
✔✔Which of the following fixed prostheses does not cover the crowns of the teeth? -
✔✔Inlay
✔✔True or False: Resin-bonded bridges are used to preserve tooth structure of the
abutment teeth. - ✔✔True
✔✔What is the use of electrosurgery in fixed prosthetics? - ✔✔To remove gingival
tissue for an impression
✔✔What is the term given to a prosthetic tooth replacement? - ✔✔Pontic
✔✔What are some of the main problems with all-ceramic crowns? - ✔✔Poor fit at the
margin, and breakage
✔✔Ms. Jones has internally stained anterior teeth that have been bothering her for her
whole life. They are not decayed and their shape and alignment are good. What might
be a good treatment for her to correct this esthetic problem? - ✔✔Veneers on stained
teeth
✔✔What are the five steps that are followed to create and, with minor modifications, to
create inlays, onlays, veneers, and bridges as well? - ✔✔Preliminary treatment
