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.

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.

Conclusion

Dr. Arshin Hotchandani. Poster No.3 Slide No. 6

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.
