3. Advantages of Veneers Include:
   1. • Minimal tooth preparation required
   2. • Porcelain veneers are stronger and more durable than composite veneers
   3. • Alternative to full coverage restoration in case of incisal fractures or tooth discoloration
   4. • Color stability
4. Disadvantages of Veneers Include:
   1. • Potential for over-contouring
   2. • Requires laboratory procedures
   3. • Porcelain enamel margins may be thin and difficult to finish
   4. • Brittle margins
   5. • Pitting by acidulated fluoride treatment
   6. • Cannot be repaired easily
   7. • Can sometimes be difficult to temporize
   8. • Color cannot be altered substantially after placement
   9. • Placement is difficult and time-consuming
5. Clinical Procedure
   1. Treatment Plan Phase
      1. 1. Check for contraindications
      2. 2. Mount study casts
      3. 3. Check posterior occlusion (anterior teeth do not function alone)
      4. 4. Confirm that there is no protrusive or lateral interference
      5. 5. Check centric anterior lingual contacts
      6. 6. Consider three key elements of esthetics: contour, position and color
