    Study Notes

    Classification System for Complete Edentulism

    • Diagnostic classifications aid in assessing treatment difficulty and planning.
    • Class I includes favorable conditions: residual bone height ≥ 21 mm, stable ridge morphology, and conducive muscle attachment location (Type A).
    • Class II shows early signs of systemic disease interactions: residual bone height 16-20 mm, limited denture stability (Type A/B), and psychosocial factors present.
    • Class III requires surgical revision for effective function: residual bone height 11-15 mm, Type C ridge morphology, and conditions demanding minor surgeries.
    • Class IV represents severe edentulous condition needing almost always surgical interventions, with residual bone height ≤ 10 mm and no resistance to denture movement (Type D).

    Purpose of Classification System

    • Establishes diagnostic and treatment procedural foundation.
    • Justifies treatment methods and associated costs to patients.
    • Facilitates patient assignment for educational purposes within dental faculties.
    • Aids in reviewing treatment outcomes.
    • Enhances communication about treatment with patients and fellow professionals.

    Patient Class Characteristics

    • Class I: Requires novice skill level for treatment; Type A muscle locations enhance retention.
    • Class II: Characterized by early systemic disease and localized oral health concerns; average residual bone height of 16-20 mm; relationships are usually Class I.
    • Class III: Needs surgical interventions; average bone height of 11-15 mm; relationships can be Class I, II, or III.
    • Class IV: Always requires complex surgical solutions; Type D maxilla presents no resistance against denture movement.

    Preprosthetic Surgery Requirements

    • Minor and major soft/hard tissue procedures may be necessary.
    • Simple implant placements and extractions leading to complete edentulism for immediate denture placement require careful planning.
    • Conditions like limited interarch space (18-20 mm), moderate psychosocial issues, and TMD symptoms may necessitate surgical intervention.
    • Acquired defects and hyperactivity of the tongue can complicate patient treatment plans.

    Understanding Refractory Patients

    • Refractory patients exhibit persistent complaints after receiving appropriate treatment.
    • They struggle to meet treatment expectations, indicating a need for tailored therapeutic approaches.
