Glossary Entry: Provisional Crown

Overview

Definition: A provisional crown is a temporary restoration used in dental procedures to protect a prepared tooth while the final crown is being fabricated. It serves as a placeholder to maintain aesthetics, function, and tooth structure integrity.

Detailed Description

Types and Variations

Variations: Provisional crowns can come in different materials such as acrylic or composite resin, with variations in color and transparency. They may be prefabricated or custom-made based on the patient’s needs.

Indications

Common Uses: Provisional crowns are commonly used after tooth preparation for crowns, bridges, or implants. They provide protection, allow for assessment of aesthetics and functionality, and maintain the patient’s comfort until the permanent restoration is ready.

Insertion and Placement

Procedure: The provisional crown is carefully placed over the prepared tooth and secured with temporary cement. It should have a proper fit and occlusion to prevent dislodgement and maintain the patient’s bite. The dentist may need to make adjustments for optimal comfort and function.

Clinical Considerations

Potential Complications

Risks: Improper placement of a provisional crown can lead to issues such as sensitivity, discomfort, or even damage to the prepared tooth. It is essential to check for any signs of infection or poor fit during follow-up appointments.

Care and Maintenance

Maintenance Requirements: Patients should be advised to avoid sticky or hard foods that can dislodge the provisional crown. Regular brushing and flossing should be done gently around the temporary restoration to prevent plaque buildup and maintain oral hygiene.
