Prosthodontics and Crown & Bridge flashcards for NEET MDS

24 of 50 cards from the Prosthodontics and Crown & Bridge deck — real questions with worked answers.

1. In complete denture prosthodontics, what does the term "prosthodontics" mean and what are its four recognized subdivisions?

   Prosthodontics is the dental specialty concerned with diagnosis, treatment planning, rehabilitation and maintenance of oral function, comfort, appearance and health of patients with missing/deficient teeth and oral/maxillofacial tissues. Its four subdivisions are: complete (removable) denture prosthodontics, partial (removable) denture prosthodontics, fixed prosthodontics (crown & bridge), and maxillofacial prosthetics.

2. Who is regarded as the "Father of Prosthodontics" and what key contribution is associated with him?

   Pierre Fauchard (1678-1761) is called the Father of Modern Dentistry/Prosthodontics. His 1728 book "Le Chirurgien Dentiste" described denture construction, and he introduced retention of full dentures using steel springs.

3. What is the difference between the "scope" goals of removable versus fixed prosthodontics?

   Removable prosthodontics replaces missing teeth and supporting structures with appliances the patient can remove (complete/partial dentures). Fixed prosthodontics (crown & bridge) restores or replaces teeth with restorations cemented/luted permanently that the patient cannot remove.

4. During complete denture patient examination, what is the significance of a Class I vs Class III ridge relationship (House classification of jaw relation)?

   Class I is normal/orthognathic ridge relation; Class II is retrognathic (maxilla forward, mandible back); Class III is prognathic (mandible forward). The ridge relation guides tooth arrangement, occlusal scheme and prognosis, with Class III often requiring crossbite arrangement of posteriors.

5. What diagnostic tool is used to record and reproduce the path of the condyle, and what does it measure?

   The pantograph (and simpler face-bow/protrusive records) records condylar movements. A pantograph traces mandibular border movements to program a fully adjustable articulator, measuring condylar inclination and Bennett (lateral) movement.

6. In treatment planning, what does Kennedy's classification describe and list the four classes.

   Kennedy's classification describes partially edentulous arches by location of edentulous spaces. Class I: bilateral edentulous areas posterior to natural teeth; Class II: unilateral posterior edentulous area; Class III: unilateral edentulous area bounded by teeth anteriorly and posteriorly; Class IV: single edentulous area anterior to (crossing) the midline.

7. What are Applegate's rules for applying the Kennedy classification (state two key rules)?

   Key rules: (1) The most posterior edentulous area always determines the classification. (2) Any edentulous area other than the one determining the class is termed a modification space, designated by number (e.g., Class II mod 1). Class IV has no modifications.

8. Differentiate between mucostatic and mucocompressive (selective pressure) impression techniques for complete dentures.

   Mucostatic (minimal pressure) records tissues at rest using free-flowing material for even pressure distribution. Mucocompressive records tissues under functional load, increasing retention under masticatory force. Selective pressure combines both—loading stress-bearing areas while relieving non-stress-bearing areas.

9. What is the purpose of a "border molding" procedure during complete denture impressions, and what materials are commonly used?

   Border molding (muscle trimming) shapes the impression borders to record the functional width and length of the vestibule/sulcus for a peripheral seal. Materials: low-fusing impression compound (green stick) or heavy-body/putty addition silicone.

10. Define centric relation (CR) as used in jaw relation records.

    Centric relation is the maxillo-mandibular relationship in which the condyles articulate in the anterosuperior position against the posterior slopes of the articular eminences, with the discs properly interposed—independent of tooth contact. It is a reproducible, retruded reference position.

11. What is the difference between centric relation (CR) and centric occlusion (CO/maximum intercuspation)?

    Centric relation is a bone-to-bone (condyle-fossa) jaw position independent of teeth. Centric occlusion (maximum intercuspation, MIP) is the relationship of teeth in maximum intercuspal contact. When CO coincides with CR it is called "centric relation occlusion"; a discrepancy is a CR-CO slide.

12. In jaw relation records, what is the average value of the freeway space (interocclusal rest space) and how is vertical dimension of occlusion derived from it?

    Freeway space averages about 2-4 mm. Vertical Dimension of Occlusion (VDO) = Vertical Dimension at Rest (VDR) minus the freeway space. VDR is measured at physiologic rest position; subtracting ~2-4 mm gives the occluding vertical dimension.

13. What are the three types of articulators classified by adjustability, with an example of each?

    Non-adjustable/simple hinge (e.g., barn-door hinge articulator); semi-adjustable—Arcon (e.g., Whip Mix, Hanau Wide-Vue) and Non-arcon (e.g., Hanau H2/Dentatus); fully adjustable (e.g., Stuart, Denar D5A) which reproduces all mandibular border movements.

14. What is the difference between an Arcon and a Non-arcon semi-adjustable articulator?

    In an Arcon articulator the condylar elements are attached to the lower member and the condylar guidance (fossa) to the upper member—mimicking natural anatomy. In a Non-arcon articulator this is reversed (condyle on upper, guidance on lower).

15. At the try-in stage of a complete denture, name three things that are verified before processing.

    At wax try-in verify: (1) esthetics—tooth shade, mould, midline, lip support, smile line; (2) phonetics—speech (s, f, v sounds); (3) occlusion and jaw relations (centric, vertical dimension), plus retention, stability and posterior palatal seal.

16. What is selective grinding (occlusal correction) performed at denture insertion and what rule guides it for working/non-working interferences?

    Selective grinding refines occlusion to achieve balanced contacts. The BULL rule guides eccentric grinding: reduce Buccal cusps of Upper and Lingual cusps of Lower (the non-supporting cusps) on the working side to remove interferences, preserving supporting cusps and vertical dimension.

17. State Hanau's Quint (the five factors of balanced occlusion).

    Hanau's Quint: (1) condylar guidance (incline), (2) incisal guidance, (3) occlusal plane orientation, (4) compensating curve, and (5) cusp angulation (cusp height). These factors are interdependent in achieving balanced articulation.

18. What is balanced occlusion in complete dentures and why is it desirable?

    Balanced occlusion is simultaneous, harmonious contact of maxillary and mandibular teeth bilaterally in centric and all eccentric positions. It stabilizes the dentures during function and parafunction, preventing tipping/dislodgement.

19. Differentiate between immediate denture and overdenture as denture design concepts.

    An immediate denture is inserted right after extraction of remaining natural teeth so the patient is never without teeth. An overdenture is a removable denture supported partly by retained tooth roots or implants beneath it, preserving alveolar bone and proprioception.

20. In fixed prosthodontics, what is the difference between a retainer, a pontic, and an abutment in a fixed partial denture (bridge)?

    An abutment is the natural tooth (or implant) that supports the prosthesis. A retainer is the restoration (e.g., crown) cemented onto the abutment. A pontic is the artificial tooth that replaces the missing natural tooth and spans the edentulous space.

21. State Ante's Law as applied to fixed partial denture abutment selection.

    Ante's Law: the combined periodontal (root) surface area of the abutment teeth should be equal to or greater than the periodontal surface area of the teeth being replaced by the pontics. It guides whether abutments can support the bridge load.

22. What is the recommended total occlusal convergence (taper) for a tooth preparation receiving a full crown, and why?

    The ideal total occlusal convergence is about 6 degrees (roughly 2-3 degrees per wall). This taper provides adequate retention and resistance form while allowing a single path of insertion and complete seating; excessive taper reduces retention.

23. List the principles of tooth preparation for a cast restoration (name at least four).

    Principles: (1) preservation of tooth structure, (2) retention and resistance form, (3) structural durability (adequate material bulk—occlusal reduction, functional cusp bevel), (4) marginal integrity (proper finish line), and (5) preservation of the periodontium.

24. Compare the chamfer, shoulder, and knife-edge finish lines used in crown preparation.

    Chamfer: distinct curved margin, good for cast metal/metal margins of PFM—conservative, easy to read. Shoulder: 90-degree butt margin giving bulk for all-ceramic/PFM porcelain margin but removes most tooth. Knife-edge/feather: minimal reduction but produces over-contoured, hard-to-read margins—generally avoided.
