When are custom provisional crowns typically utilized over prefabricated crowns?

Custom provisional crowns are typically utilized when a better fit is required because they are specifically designed and fabricated to match the unique contours and dimensions of an individual's tooth. This tailored approach ensures that the provisional crown can provide optimal aesthetics, functionality, and comfort, which is particularly important during the interim period before the final restoration is placed.

In scenarios where the anatomy of the prepared tooth is complex or when there are significant aesthetic concerns, a custom provisional crown can serve to maintain proper occlusion and protect the tooth structure while also preserving the patient's smile. Conversely, prefabricated crowns, while convenient and time-saving, may not offer the same level of precision and comfort due to their generic sizing and shape. Therefore, they are not the ideal choice in situations demanding a higher level of customization.
