What should be done if the margins of the provisional are not adequate?

When the margins of a provisional restoration are not adequate, adding material at the inner aspect of the margin is the appropriate course of action. This technique allows for the restoration to achieve a better fit and seal against the tooth preparation, which is essential for maintaining gum health and minimizing sensitivity. A properly sealed margin helps prevent plaque accumulation and protects the tooth from temperature changes and other irritants.

This adjustment can also enhance the aesthetic appearance of the provisional, creating a more natural-looking tooth and improving the overall comfort for the patient. By selectively adding material, you can refine the provisional without having to discard the entire restoration, saving time and resources.

In contrast, replacing the entire provisional may be unnecessary if a less invasive adjustment can achieve an acceptable outcome. Adjusting the occlusion might correct bite issues but would not address the inadequacy of the margins directly. Leaving the provisional as is would likely compromise the success of the treatment and can lead to further complications down the line, such as discomfort or the failure of the final restoration.
