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.
