What is required prior to the preparation of a tooth for making a custom provisional?

Preliminary impression
Final impression
Dental cleaning
Tooth extraction

The correct answer is: Preliminary impression

Prior to preparing a tooth for a custom provisional, a preliminary impression is required. This is because a preliminary impression is used to create a replica of the teeth and surrounding tissues, which can then be used to create a temporary crown or bridge. Final impressions are not needed at this stage, as they are used for creating a permanent restoration. Dental cleaning is important for overall oral health, but it is not directly related to the preparation of a tooth for a provisional. Tooth extraction would not be necessary in this scenario, as the tooth is being preserved and temporarily restored.
