Clinical Case Management and Treatment Planning Guidelines
This document outlines the clinical considerations for managing complex cases within the scope of a DMD student, focusing on restorative strategies, patient communication, and long-term care planning.
1. Managing Complex Occlusal Cases
When presented with a patient requiring front teeth restoration but exhibiting a collapsed bite or complex occlusion, practitioners must evaluate the feasibility of treatment within their professional scope.
Scope of Practice and Vertical Dimension
- Full Mouth Rehabilitation: This is generally considered beyond the scope of a student/general practitioner and requires specialist referral.
- Habitual Bite: If a patient has a functional habitual bite, avoid attempting to find Centric Relation (CR) unless necessary, as CR is a reference point primarily used when teeth are absent or a total reconstruction is planned.
- Raising the Vertical Dimension (OVD): If a patient is biting on only a few teeth (e.g., four lower teeth), the bite may need to be raised to create restorative space.
Restorative Options for Increasing OVD
| Option | Pros | Cons |
|---|---|---|
| Composite Buildups | Conservative, immediate. | High risk of fracture if tripodization is not achieved; lacks long-term durability under heavy loads. |
| Injection Molding | Aesthetic, uses composite. | Often considered temporary; may not withstand heavy bruxism. |
| Chrome Overlay Denture | Thinner than acrylic, durable, reversible. | Requires specific design to overlay the 2–4 points of contact. |
| Acrylic Partial/Overlay | Easy to adjust and add to. | High risk of snapping/fracture; requires at least 2mm of thickness for strength. |
Recommendation: For patients with financial constraints, a chrome partial denture with extensions to overlay specific teeth can raise the bite effectively without the permanence or fragility of full-composite buildups.
2. Patient Communication and Informed Consent
Effective communication is the cornerstone of managing patient expectations, especially in “Class 2, Division 2” cases where high overbites and heavy stresses increase the risk of restoration failure.
- Identifying Barriers: Clearly explain the physical limitations of the patient’s mouth (e.g., proclined teeth or bruxism) that may cause dentures to fracture.
- Liability and Warnings: Ensure the patient understands that while a more affordable option (like an acrylic denture) is being provided, the risk of breakage is higher due to their specific bite.
- Value Proposition: Frame crowns and high-end restorations as “luxurious yet beneficial” investments in their long-term health, rather than just “practicing” a requirement.
3. Proactive Treatment Planning (The 011 Examination)
Students are encouraged to look beyond the immediate chief complaint during initial checkups (011s) to identify preventative and strengthening opportunities.
Key Areas of Focus:
- Abutment Teeth: Before designing a chrome denture, evaluate the health of the abutment teeth. Large amalgam fillings with leaking margins or subgingival extensions should be considered for crowns to ensure the denture fits a stable foundation.
- Replacing Old Restorations: Do not leave semi-cracked fillings, marginal creep, or leaking composites in the mouth if a chrome denture is planned. If these fillings fail later, the denture will no longer fit.
- Conservative vs. Proactive: While being conservative is important, do not wait for a cusp to break before suggesting a crown. Aim to strengthen the tooth before catastrophic failure occurs.
4. Long-term Care and Specialist Referrals
Referring a patient to a specialist (Prosthodontics, Periodontics, or Endodontics) does not end the student’s responsibility.
- Maintenance: Due to long waiting lists for specialist care, students must keep these patients in their books for six-monthly recalls.
- Stabilization: Ensure the patient’s oral health is maintained so their condition does not deteriorate while waiting for advanced treatment.
5. Clinical Mentorship
To maximize learning and patient outcomes, students should:
- Consult Tutors Early: Speak with tutors before the patient arrives to discuss potential “out-of-the-box” solutions.
- Request Guidance: Specifically ask tutors to help identify areas where teeth can be strengthened or where indirect restorations may be beneficial.
- Document Everything: Even if a patient declines a crown, include it in the treatment plan to demonstrate that the need was identified and the risks of non-treatment were explained.
