Minimal preparation porcelain veneers were developed to combine esthetics and function while preserving enamel. They were initially recommended by Christensen and Quinn. The document describes a case where diastemas in the maxillary anteriors were treated with minimal preparation veneers after old composite restorations were removed. The veneers were bonded using etching, silane, and bonding agent. The result enhanced the patient's smile without aggressive tooth reduction.

1. Minimal Preparation Veneers
Increasing esthetic demands have led to the
development of ceramic systems that wed
esthetics with function with preservation of
sound enamel.
Noninvasive porcelain veneers were initially
recommended by Christensen and Quinn et al.

Patient presented with a complaint of diastemas in
her maxillary anteriors which was treated using
composites but not to the patients satisfaction.The
dental health was evaluated and was good with no
periodontal problems.

3. Diagnosis and Treatment plan
Retracted view Occlusal view
Tooth preparation included removal of the old
composite restoration and providing a subtle chamfer
as a margin extending linguo-proximally.The incisal
margin was planned as a butt joint.

4. Bonding procedure:
1)Etching of veneers 2)Application of silane 3)Acid etching the tooth
coupling agent surface
4)Application of bonding 5)Placement of veneers using 6)Removal of excess
agent luting cement and curing cement;finishing and polishing

6. Conclusion
By using minimal preparation of natural tooth
structure and ultrathin porcelain veneers, we can
enhance the patient’s smile without aggressive tooth
reduction.The lamination effect of the bonding
process allows for strengthening of the thin ceramic
material, and the ceramist can achieve excellent
esthetics through layering of the stacked porcelain.
