Fabricate Ideal Provisional Crown Before Impression

The permanent crown looks short at #4 buccally (Fig.1), although it is acceptable occlusally (Fig.2).  It appears that there is excess gingiva buccally (Fig.3 *).  A provisional crown needs to remade to press the buccal gingiva so that the buccal contour of the final restoration (Fig.4 curved line) can match that of the neighboring teeth.

In fact the crown is cemented.  Later the patient returns for redo, because of food impaction.  The abutment is changed from 5.8x4(2) to 4.8x5.5(1) mm.  The more critical change is to fabricate a crown with buccal prominence (Fig.5 black curved line).  The patient is satisfied after cementation of the new crown (Fig.6).

Ideally, the provisional should have been modified to an ideal form prior to impression.
