Prosthodontics Practice Exam Questions and Verified Answers, 100% Guarantee Pass (Latest 2025) (2010)Which of the following is the primary cause of patient complaints of fullness, soreness and lack of retention in a maxillary complete denture?

• Flange borders that are too thick
• Overextended labial flange borders
• A deep labial notch
• Overextended posterior border - Correct Answers ✅B.

Overextended labial flange borders will cause the denture to dislodge when peri-oral muscle activity ensues. This is why accurate border molding is so critical to proper denture construction. In addition, it is common to see vesibular ulceration secondary to the overextension. And finally, the additional material may convey a sense of fullness. Properly located, but excessively thick, flanges may also mimic this symptom, but usually without the soreness/displacement issues. Zarb, et al., 12th ed., p 420 - 421 (2010)Which of the following MOST COMMONLY causes cheek biting in denture patients?

• Using 0 degree teeth

• Lack of horizontal overlap in the posterior teeth - Correct

Answers ✅D. Lack of Horizontal overlap in the posterior teeth Small lesions on the Buccal mucosa of the cheek in line with the occlusal plane indicate that the patient is biting the cheek during mastication. This problem usually can be corrected by reducing the buccal surface of the offending mandibular tooth to create additional horizontal overlap, thus providing an escape for the Buccal mucosa. Zarb et al., 12th ed., p 420 (2010)Construction of a fixed partial denture, replacing the maxillary first molar (#3) and both premolars (#4 and 5) using only the canine (#6) and second molar (#2) as abutments violates Ante's law. Still, it should be considered as a treatment option.

• Both statements are TRUE
• Both statements are FALSE
• The first statement is TRUE; the second is FALSE
• The first statement is FALSE the second is TRUE - Correct

Answers ✅C. The first statement is TRUE, the second statement is FALSE It is unwise to provide a FPD when the root surface area of the abutment was less than the root surface area of the teeth being replaced. If the first molar and both premolars are 2 / 4

Prosthodontics Practice Exam Questions and Verified Answers, 100% Guarantee Pass (Latest 2025) missing; however, the FPD is not considered a good risk because the missing teeth have a greater total root surface area than the potential abutments. Rosenstiel et al., 3rd ed., p 69 - 71 (2010)Preparation of the functional cusp is an integral part of the occlusal reduction phase for either a full- or partial-veneer

restoration. The purpose of "beveling" the cusp is to:

• Relieve the functional cusp from additional stresses when

the restoration is loaded in the long axis of the tooth

• Provide space for an adequate thickness of restorative

material in an area of heavy occlusal contact

• Enhance resistance form when Buccal to lingual forces are

applied to the casting

• Serve as a positive stop when the casting is seated during

cementation - Correct Answers ✅B. Provide space for an adequate thickness of restorative material in an area of heavy occlusal contact An integral part of the occlusal reduction is the functional cusp bevel. A wide bevel on the lingual inclines of the maxillary lingual cusps and the Buccal inclines of mandibular Buccal cusps provides space for an adequate bulk of metal in an area of heavy occlusal contact. Shillingburg, et al., 3rd ed., p 127 3 / 4

Prosthodontics Practice Exam Questions and Verified Answers, 100% Guarantee Pass (Latest 2025) (2010)When placing a 5-unite FPD where the maxillary first premolar and first molar are missing, leaving the second premolar as a pier abutment, and the cuspid and second molar as abutments, a non-rigid key/keyway connector would

be best placed on the:

• Distal side of the retainer on the middle abutment (pier

abutment)

• Mesial side of the middle abutment
• Mesial of the second molar
• Distal of the cuspid - Correct Answers ✅a. Distal side of

the retainer on the middle abutment (pier abutment) A 5-unit FPD replacing the maxillary 1st molar and 1st premolar, the middle abutment can act as a fulcrum during function, with possible unseating of one of the other abutments. One approach is a nonrigid dovetail connector between the molar pontic and the second premolar.Rosenstiel, et al., 3rd ed., p 69-70 (2010)A patient selects the option of a 5-unit ceramometal fixed bridge in order to replace a molar and a premolar. She also prefers a PFM for a tooth that requires full coverage. How should the preparations or the long span bridge abutments differ from that of the single crown in order to increase retention?
