Preformed laminate resin veneers should be adapted closely to the teeth to reduce the thickness of the composite layer. Minimal voids at the composite, veneer, and tooth junctional margin will result. Composite resins are difficult to finish, but laminate veneer can be highly polished. Poorly finished veneer surfaces appear to abrade to a smoother surface with toothbrushing while poorly finished composite surfaces remain rough. To reduce material loss from abrasion, the veneer restoration should be highly polished. Polishing the veneer at the gingival margin is particularly important to gingival health. Only rough veneer surfaces will be improved by toothbrushing abrasion. Special instructions should be given to patients with laminated veneers to reinforce proper oral hygiene and to discourage use of highly abrasive dentifrices. Continued monitoring of plaque accumulation should minimize problems related to oral hygiene.
