Placement of a preformed metallic crown with significant tooth preparation becomes necessary when a tooth requires extensive restoration due to severe decay, trauma, or structural compromise. This approach involves reshaping the tooth to accommodate the crown, ensuring proper retention and stability. Metallic crowns are particularly durable and can withstand heavy occlusal forces, making them ideal for posterior teeth.
Restoring function and durability protects the remaining tooth structure, preventing further damage or fractures. The metallic crown provides a long-lasting solution, allowing the patient to chew comfortably and maintain oral health. Additionally, the procedure reduces the risk of complications such as pulp exposure or infection, ensuring the tooth remains viable for years to come.
Ensure proper preparation and fit to avoid marginal discrepancies or failure. Pay close attention to the depth and angulation of the preparation to ensure the crown seats securely without interfering with the patient’s bite. Use radiographic guidance to verify the fit and margins of the crown, and educate the patient on proper care to extend the lifespan of the restoration.
