A temporary crown is a provisional restoration used in dentistry during permanent crown or implant treatment. It acts as a short-term solution to protect the prepared tooth (or implant site) until the final restoration is ready, typically worn for 1–3 weeks.
Core Functions
Protection: Covers the exposed tooth/implant neck to shield it from food debris, bacteria, and temperature sensitivity, reducing inflammation risk.
Space Maintenance: Prevents adjacent teeth from shifting into the gap or opposing teeth from overerupting, preserving the correct occlusion space.
Function & Aesthetics: Restores basic chewing ability (for posterior teeth) and natural appearance (critical for anterior teeth, e.g., matching tooth shade).
Guidance for Final Restoration: Tests occlusion height and tissue adaptation, providing data to refine the permanent crown's design.
Common Materials
Resins (most widely used): Self-curing acrylic resin (fast, cost-effective for short-term use) and light-curing composite resin (better aesthetics/strength, suitable for longer wear).
Metal-reinforced resins: For posterior teeth with heavy occlusion, adding metal 支架 (framework) to enhance durability.
Clinical Notes
Patients should avoid hard foods (e.g., nuts, bones) to prevent cracking. Maintain oral hygiene by gently brushing; report looseness, pain, or fit issues promptly for adjustments.
