Study Notes

Removable Prosthodontics

  • Focuses on replacing teeth and contiguous structures for edentulous or partially edentulous patients using artificial substitutes that are removable.

Partial Denture

  • A dental prosthesis that restores one or more but not all natural teeth and can be either removable or fixed.

RPD (Removable Partial Denture)

  • Defined as any removable prosthesis replacing some teeth in a partially dentate arch, removable by the patient at will.

Patient and Dentist Concerns

  • Patients prioritize aesthetic restoration and mastication.
  • Dentists emphasize preservation and support of remaining teeth and supportive structures.

Major Categories of Partial Tooth Loss

  • Tooth-supported and tooth-and-tissue-supported classifications.

RPD Expectations

  • RPDs should be socially acceptable, comfortable, stable, and maintainable.

Key Concepts of a Well-Functioning RPD

  • Stability, support, and retention are essential for effective performance.

Stability

  • Refers to an RPD's firmness and resilience against functional, horizontal, or rotational stresses.

Support

  • Characterized by maximum tissue coverage to facilitate load distribution.

Retention

  • The capacity of an RPD to resist dislodgement forces along its placement path.

Bone Loss Insights

  • Bone loss is greater posteriorly than anteriorly.
  • Generally produces broader mandibular arches while constricting maxillary arches.

Physiological Purpose of Alveolar Bone

  • To hold natural teeth in place.

Tooth-Supported Prostheses

  • Direct resistance to functional forces provided by natural teeth, with retention from clasps.

Role of the Residual Ridge

  • Assists in functional stability of the prosthesis.

Residual Ridge Movement

  • Typical movement ranges from 1 to 3 mm in a healthy residual ridge.

Distal Extension

  • Provides maximum support in the posterior tissue region of the RPD.

Advantages of RPD Over FPD

  • Cost-effective and quicker fabrication times compared to fixed partial dentures.

Disadvantages of RPD Over FPD

  • Potential strain on abutment teeth, loss of tissue support, and risks of caries beneath clasps.

Kennedy Classification Overview

  • Based on the relationship of edentulous spaces to abutment teeth and the prevalence of each condition in the population.

Applegate's Rules

  • Modifications to Kennedy's original classifications addressing specific factors in determining classifications.

Kennedy Classifications

  • Class I: Bilateral edentulous areas located posterior to remaining teeth.
  • Class II: Unilateral edentulous area located posterior to remaining teeth.
  • Class III: Unilateral edentulous area with natural teeth remaining both anteriorly and posteriorly.
  • Class IV: Anterior tooth-bounded edentulous area crossing the midline.

Applegate's Rules Insights

  • Rule 1: Teeth scheduled for extraction are treated as edentulous spaces in classification.
  • Rule 2: Edentulous spaces not to be restored are excluded from classification.
  • Rule 3: The most posterior space dictates the class of the arch.
  • Rule 4: Additional edentulous areas are treated as modifications and designated by numbers.
  • Rule 5: Only Classes I, II, and III can have modifications, regardless of the length of edentulous spaces.
