What may occur if undercuts are not managed during provisional crown fabrication?

• A. Better adaptation
• B. Locking on to the prepared tooth
• C. More comfort for the patient
• D. Faster laboratory turnaround

Answer: (B)

During the process of provisional crown fabrication, addressing undercuts is crucial to ensure the provisional crown fits properly. If undercuts are not managed, it can result in the provisional crown locking onto the prepared tooth. This occurs because the material used for the crown may become trapped in the undercut areas, making it difficult or impossible to remove the crown without damaging either the crown itself or the tooth structure. Locking onto the prepared tooth can lead to a range of complications, including discomfort for the patient, potential damage to the tooth, and challenges in later stages of treatment, such as final crown placement. A properly managed provisional should allow for easy removal while maintaining the desired fit and aesthetics. Therefore, understanding the implications of undercuts is essential in dental assisting and ensuring successful patient outcomes.
