Study Notes

Introduction

Full coverage restorations, also known as full crowns, cover the entire visible portion of a tooth.
These restorations improve the tooth's structural integrity, aesthetics, and function.
They are commonly needed for severely damaged or decayed teeth.

Indications for Full Coverage Restoration

Deep decay or cavities.
Significant trauma or injury.
Large fillings that compromised the tooth's integrity.
Severe abrasion or erosion.
Uncorrectable discoloration.
Strengthening teeth after root canal treatment.
Severe fractures beyond repair with fillings.
To support a dental implant.

Materials Used in Full Coverage Restoration

Metal alloys (e.g., gold, nickel-chromium, titanium alloys):
- Strong and durable, resisting chewing forces.
- May not be as aesthetically pleasing as other options.
Porcelain-fused-to-metal (PFM):
- Combines metal's strength with porcelain's aesthetics.
- More natural-looking than all-metal options.
- Porcelain fused to a metal substructure.
All-ceramic restorations (e.g., zirconia, lithium disilicate):
- Provide a highly aesthetic and natural appearance.
- Available in various colors to match surrounding teeth.
- Generally stronger than PFM, but may require more support in some cases.
All-resin:
- Less durable than other options.
- Best for minimal stress situations or interim restorations.

Procedure of Full Crown Restoration Process:

Diagnosis and Treatment Plan:
- Assess the tooth and surrounding areas.
- Utilize X-rays or other imaging to evaluate damage.
- Discuss restoration options with the patient.
Preparation of the Tooth:
- Remove decayed or damaged tooth structure.
- Create a precise shape for crown fit.
- Performed under local anesthesia.
Impression and Molding:
- Create precise molds of the prepared tooth using impressions.
- These impressions are used to fabricate the restoration.
Fabrication of the Crown:
- The dental lab creates the crown from a mold.
- This stage can take several days or weeks.
Fitting and Cementation:
- Trial fit to ensure proper alignment.
- Adjust tooth preparation and crown alignment if necessary.
- Cement the crown securely to the tooth.
Post-Treatment Care:
- Receive instructions for proper oral hygiene.
- Schedule follow-up appointments.

Post-Operative Considerations

Sensitivity:
- Temporary sensitivity is common and subsides.
Proper Oral Hygiene:
- Maintain exceptional oral hygiene.
Checkups/Follow-up Appointments:
- Regular visits are crucial for crown monitoring.

Potential Complications

Post-operative sensitivity:
- Temporary soreness is common, usually resolving in a few days.
Allergies to materials:
- Allergic reactions to materials are possible.
- Patient sensitivity history is crucial.
Inadequate fit:
- Poor fit leads to discomfort, pain, and complications.
Fracture/Loss of Restoration:
- Improper technique or material compromises the crown.
Damage to adjacent teeth:
- Adjacent teeth may face structural risks and sensitivity.

Aesthetics

Full coverage restorations enhance the appearance of damaged teeth.
Materials offer a natural aesthetic mimicking surrounding teeth.

Considerations for Specific Situations

Health Conditions:
- Patients with underlying health issues may require special care.
Oral Habits:
- Bruxism or clenching can stress the restoration.
Patient Preferences:
- Tailor restorations to the patient's aesthetic and functional needs.
Budget Constraints:
- Discuss material costs with patients.
