Study Notes

Diagnosis & Treatment Planning in FPD

FPD (Fixed Partial Denture) treatment involves a logical sequence of steps to regain the functionality and aesthetics of a patient's teeth.
Diagnosis involves gathering information from various sources for proper treatment planning.
Elements of Diagnosis are:
- Medical and Dental History
- TMJ (Temporomandibular joint) & Occlusal Evaluation
- Muscle of Mastication Examination
- Intraoral Examination
- Cast Analysis of Teeth
- Full-mouth Radiographic Evaluation
Treatment Planning involves analyzing collected data and formulating a written plan, to be discussed with the patient before irreversible procedures.
Treatment Sequence involves different phases:
- Phase I (Symptomatic Treatment): Addressing immediate pain or issues like fractured teeth, pulpitis, abscesses, or gingivitis, as well as non-acute problems like lost crowns or broken veneers.
- Phase II (Stabilization Phase): Focuses on improving oral hygiene and tackling caries (cavities).
- Phase III (Preparatory Phase): Includes preliminary treatments such as orthodontics, surgery, endodontics, and periodontics.
- Phase IV (Definitive Phase): Consists of restoring missing teeth with occlusal adjustments and dental restorations.
- Phase V (Follow-up Phase): Regular check-ups to monitor treatment outcomes.
Treatment Planning for Single Tooth: Factors influencing restoration selection:
- Tooth Structure Destruction: Amount of tooth structure remaining dictates the choice of material. For extensive damage, cast metal or ceramic may be preferred over amalgam or composite resin.
- Esthetics: If the tooth is in a highly visible area, the cosmetic look of the restoration is important. Partial or full veneers, metal-ceramic or all-ceramic crowns are options.
- Plaque Control: Cements restorations require meticulous plaque control to ensure success.
- Financial Considerations: The cost of treatment is a factor, patients are guided but ultimately make the choice.
- Retention: Full veneer crowns provide maximum retention, but for single-tooth restorations, it's less critical.
Treatment Planning for Missing Tooth: Why replacing missing teeth is crucial:
- Structural Integrity: Loss of a tooth disrupts the arch's integrity, causing other teeth to shift into the space. This can lead to crowding, tilting, or overeruption of opposing teeth.
- Occlusal Balance: Restoring the missing tooth with a prosthetic replacement is necessary to maintain a balanced occlusion.
- Prosthetic Options:
  - Removable Partial Denture: A removable replacement that can be taken out for cleaning.
  - Tooth-Supported Fixed Partial Denture: A non-removable bridge that uses existing teeth as supports.
    - Conventional Type: A bridge with crowns attached to abutment teeth (supporting teeth).
    - Resin Bonded Bridge: A bridge that is bonded to the abutment teeth using adhesive resin.
  - Implant-Supported Fixed Partial Denture: A bridge supported by dental implants placed in the jawbone.
Factors Affecting Prosthesis Type Selection:
- Biomechanical Considerations:
  - Span Length: Longer spans are less rigid and more prone to flexing, increasing stress on the abutment teeth.
  - Double Abutment: Two teeth are used as supports for a bridge.
  - Arch Curvature: The shape of the dental arch can influence the design of the bridge.
- Prospective Abutment: The condition of the supporting teeth, including crown-root ratio, root configuration, and periodontal ligament area, must be evaluated.
- Esthetic Requirements: Front teeth (anterior) require aesthetically pleasing restorations.
- Patient's Desire: The patient's preferences and needs are respected in the treatment plan.
- Financial Factors: The cost of various prosthetic options impacts the decision.
- Clinician's Skill: The dentist's experience and expertise are important.
- Laboratory Support: The quality of the dental lab that fabricates the prosthesis affects the final outcome.
- Patient's Motivation and Cooperation: Patient commitment to oral hygiene and care is essential for treatment success.
Ante's Law: The root surface area of abutment teeth should equal or exceed the root surface area of the teeth being replaced.
