Provisional restorations for veneers.

Provisionals for veneers can be a difficult and sometimes time-consuming procedure for both dentist and patient and the result may require repair andlor replacement. Generally, fewer visits with fewer problems usually leads to a better dentist-patient relationship. The author has used all of the veneer provisional placement techniques cited in this column and has enjoyed the most success when making a preoperative impression with a bis-acrylic material. If the case involves multiple units, no etch is used most often, but if there are only one or two veneers, a small amount of etch and bonding agent are placed prior to the bis-acrylic.
