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.
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.
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.
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.
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.
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.
Associated Terms: Temporary cement, provisional bridges, interim restorations, temporary crowns for pediatric dentistry.
Recent Developments: Advances in digital dentistry have allowed for faster and more accurate fabrication of provisional crowns using CAD/CAM technology. These digital workflows improve precision and patient satisfaction.
Regulations: Dentists should follow manufacturer guidelines for the use of temporary materials, ensure proper sterilization of instruments, and educate patients on the temporary nature of the provisional crown.
