CDT Partial Dentures Final Exam 2025/2026 Questions
with Verified Answers
1. Which component of a Removable Partial Denture provides retention?: Clasps
2. Which is the purpose of a surveyor?: Identifies height of contour
3. Which is a major connector?: Open or closed horseshoe
4. Which is a minor connector?: Connection between major connector and clasp.
5. Where a properly constructed lingual bar is not possible due to its encroach- ment
on the 4mm distance from the gingival tissues, a is an excellent
alternative.: Ḳennedy Bar
6. A clasp should provide: Retention and Reciprocation
7. Which is a ḳey factor in a successful RPD pattern construction?: Use pliable
preformed parts that readily conform to surfaces of the refractory cast.
8. A general guideline for placing a rest is?: Rests are almost always placed on teeth adjacent to
edentulous spaces because that is where support requirements are greatest.
9. Before processing a denture base: Wax seal the denture base to the cast.

, 10. Tooth-borne: c
11. Bilateral anterior extension: d
12. Unilateral distal extension: b
13. Bilateral distal extension: a
14. Requires tooth and tissue support: a, b, d
15. Requires tooth support only: c
16. How is the Ḳennedy classification determined?: By the most posterior edentulous area.
17. What is a modification to the Ḳennedy classification?: A modification is any edentulous area
anterior to the most posterior edentulous area.
18. How does a Class IV arch differ from a Class III arch?: The anterior edentulous area must cross the
midline to be classified as a Class IV
19. What is a fulcrum line?: It is an imaginary line around which a removable partial denture could rotate.
20. How is rotation around the fulcrum line neutralized?: By using rests, direct retention, and
supporting tissues
21. Describe the type of support needed for Class I, II, III, IV cases.: Ḳennedy Class I, II, and IV
RPD's require tooth and tissue support for stabilization, while Class III requires only tooth support.
22. Why should a cast circumferential clasp never engage the mesiobuccal un- dercut on
