Question

Quizplus · Accepted Answer

Laboratory-fabricated coverage is typically used when several teeth have been prepared, such as in a multiunit bridge. This allows for a more precise and accurate fit, as well as better aesthetics, than a chairside provisional restoration. Option A is not sufficient since the size and shape of the teeth may also be addressed with direct restorations. Option C is not necessary since a patient may be given a pre-fabricated provisional restoration. Option D is also not a typical reason to use laboratory-fabricated coverage, as there are other materials that can be used to avoid allergic reactions.
