VENEERS ( CLASSIFICATION )

Veneers can be basically classified in to two types

1. partial veneers
2. full veneers.

Partial veneers are indicated for the restoration of localized defects or areas of intrinsic discoloration .

 Full veneers are indicated for the restoration of generalized defects or areas of intrinsic staining involving the majority of the facial surface of the tooth.

Full veneers can be further subdivided in to two types based on tooth preparation.

1. Full veneer with window preparation design that extends to gingival crest and terminates at the facioincisal angle.  

2. Full veneer with i ncisal-lapping preparation design extending subgingivally that includes all of incisal surface.

Full veneers can be accomplished by a direct or an indirect technique.
