Study Notes

Treatment Planning and Treatment Sequence for Crowns and Fixed Partial Dentures

  • This presentation details the planning and execution of dental crown and fixed partial denture (FPD) procedures.
  • Essential aspects of treatment planning include patient assessment, oral hygiene evaluation, and tooth-specific considerations.
  • The overall approach emphasizes a holistic approach, considering the patient's needs, the status of the entire mouth, and the unique characteristics of each tooth.

Planning and Making Crowns

  • History and Examination:
    • Patient attitude and informed consent are crucial.
    • Evaluating factors such as patient age, sex, and social history is vital.
    • The cost of treatment should be discussed.
  • Considering the Whole Mouth:
    • Oral hygiene should be assessed.
    • The condition of remaining teeth influences treatment.
  • Considering the Individual Tooth:
    • Evaluate the value of each tooth.
    • Include appearance, condition of the tooth's crown, pulp, periodontium, occlusion, and root length.
    • The need for a core restoration is essential to assess.

Designing and Planning Bridges

  • Factors Affecting Bridge Design:
    • Support from existing teeth.
    • Conservation of surrounding tooth structure.
    • Ease of cleaning/maintenance.
    • Aesthetic appearance is also a consideration.
  • Assessment of Abutment Teeth:
    • Radiographic examinations are necessary for diagnosis and planning of abutment teeth.
    • Assess pulp condition.
    • Existing restorations, cavity liners, and residual caries should be removed.
    • Consider endodontically treated, unrestored teeth, root surface area, root shape and angulation, periodontal disease status, and biomechanical considerations.

Special Problems in Designing and Planning Fixed Partial Dentures (FPD)

  • Replacing a single missing tooth
  • Designing cantilever FPDs
  • Dealing with mesially tilted molar abutments
  • Using pier abutments
  • Replacing multiple anterior teeth (canines and others).

Sequence of Treatment

  • Treatment of Symptoms: Address immediate concerns.
  • Stabilization of Deteriorating Conditions: Deal with underlying issues and concerns.
  • Definitive Therapy: Involves final treatments and the chosen course of restorative procedures.

Additional Topics

  • Age Considerations: Upper age limits are not a consideration, as long as patients are otherwise healthy and eligible for care. This is not applicable to all. Lower age limits for crowns and bridges vary.

  • Sex Considerations: Patients should be evaluated individually based on their concerns, regardless of sex.

  • Oral Hygiene: Necessary for supporting the planning of any crowns or bridges.

  • Cost vs. Care: Balancing the cost of treatment with the desired outcome of the procedure.

  • Important considerations for the clinical decision making process for an ideal restorative approach.

  • Understanding of tooth structure: Analyze the shape, size, and complexity of missing teeth.

  • Occlusion Assessment: Important factors to assess in tooth and treatment planning.

  • The value of teeth: Teeth are valuable for their function, appearance, and position.

  • Considerations for special patient cases: Teenagers in puberty

  • Importance of treatment planning before treatment: Important for a successful outcome

  • Assessment of Abutment Teeth: Specific procedures to be evaluated and assessed.

  • Treatment Decision Making: Making an informed decision supported by data.
