1. A 67-year-old completely edentulous patient presents for
fabrication of a new maxillary complete denture. During
examination, the clinician observes a highly mobile, displaceable
anterior maxillary ridge covered by flabby tissue. Which impression
technique is MOST appropriate for obtaining an accurate definitive
impression?
A. Heavy-body elastomeric impression of the entire ridge with uniform
pressure
B. Mucocompressive impression using zinc oxide-eugenol throughout
C. Selective-pressure impression with relief over the flabby tissue
D. Alginate impression under maximal finger pressure
E. Border molding followed by complete tissue compression during final
impression
Answer: C. Selective-pressure impression with relief over the flabby
tissue
Rationale: The flabby anterior maxillary ridge is easily displaced by
impression pressure. A selective-pressure technique allows stable
supporting tissues to receive controlled pressure while relieving the
mobile tissue, thereby reducing distortion and improving denture
stability. A mucocompressive technique can displace the tissue during
impression making and produce an inaccurate denture base.

,2. A patient with a severely resorbed mandibular ridge requires a
complete denture. Which anatomical factor is MOST important for
maximizing mandibular denture stability?
A. Increasing the vertical dimension substantially
B. Positioning the mandibular teeth directly over the residual ridge
regardless of tongue position
C. Maximizing denture-bearing area and maintaining the neutral zone
relationship
D. Reducing the polished surface area
E. Eliminating all posterior occlusal contacts
Answer: C. Maximizing denture-bearing area and maintaining the
neutral zone relationship
Rationale: Mandibular denture stability is strongly influenced by the
available denture-bearing area, residual ridge anatomy, muscular
forces, and correct positioning within the neutral zone. Proper tooth
placement allows the tongue, lips, and cheeks to stabilize rather than
dislodge the prosthesis.
3. During complete denture fabrication, the clinician determines
that the patient's mandibular occlusal rim is too high. Which
clinical consequence is MOST likely?
A. Increased interocclusal rest space
B. Premature lip support loss and altered phonetics
C. Automatic improvement in mandibular stability
D. Decreased lower facial height
E. Elimination of the need for a facebow
Answer: B. Premature lip support loss and altered phonetics
2
,Rationale: Excessive occlusal-rim height can distort lip support, alter
the relationship of the rim to the lip and tongue, and interfere with
phonetics. Proper rim dimensions are established using facial
proportions, phonetics, occlusal plane orientation, and the patient's
existing anatomy.
4. A patient repeatedly fractures the acrylic base of a maxillary
complete denture along the midline. Which factor should be
investigated FIRST?
A. Tooth shade
B. Denture base thickness and fit
C. Salivary pH alone
D. Gingival shade
E. Posterior palatal seal only
Answer: B. Denture base thickness and fit
Rationale: Midline fracture commonly results from flexure caused by
inadequate base thickness, poor adaptation, excessive occlusal forces,
ridge anatomy, or combinations of these factors. The clinician should
evaluate the fit, occlusion, base thickness, and underlying anatomy
rather than simply repairing the fracture repeatedly.
5. A 58-year-old patient has a severely resorbed mandibular ridge
and poor denture retention despite appropriate impression
technique. Which treatment option provides the MOST predictable
improvement in retention when medically and anatomically
appropriate?
A. Increasing denture tooth size
B. Increasing vertical dimension by 5 mm
C. Implant-retained mandibular overdenture
3
, D. Eliminating the lingual flange
E. Using a harder acrylic resin
Answer: C. Implant-retained mandibular overdenture
Rationale: Implant-supported or implant-retained mandibular
overdentures can substantially improve retention, stability, function,
and patient satisfaction in appropriately selected edentulous patients,
particularly when severe ridge resorption compromises conventional
denture stability.
6. Which statement BEST describes the primary function of the
posterior palatal seal in a maxillary complete denture?
A. It prevents mandibular denture movement
B. It compensates for polymerization shrinkage and helps maintain
posterior border adaptation
C. It determines the patient's centric relation
D. It increases anterior tooth display
E. It eliminates the need for border molding
Answer: B. It compensates for polymerization shrinkage and helps
maintain posterior border adaptation
Rationale: The posterior palatal seal contributes to retention by
maintaining intimate contact between the denture base and posterior
palatal tissues. It also compensates, within limits, for processing
changes and dimensional alterations of the denture base.
7. During fabrication of a complete denture, a patient has difficulty
pronouncing the “S” sound. Which prosthodontic relationship
should receive particular attention?
