Porcelain Veneer

7.Isolate teeth to be veneered with interproximal strips to protect adjacent teeth (not being
veneered) from the etchant.

8.See next step if using a self-etching system such as SE Bond or Prelude SE. Otherwise etch
tooth, wash and dry (assuming Photo Bond is being used).

9.Place a thin coat of Photo Bond on the etched tooth.

If the prep is all or mostly all dentin and the veneer is fully light curable, then you may use self-etching
SE Prime, then SE Bond, rather than etch and Photo Bond. Also Prelude SE works well. Note that with
SE Bond, everything must be cured at once; no pre-curing of the SE Bond is permitted since it
thickness would preclude proper veneer adaptation to the tooth. Prelude SE, being much thinner, may
be light cured in advance of placing the veneer if care is taken to prevent pooling (air thin before curing).

10.Remove matrix strips prior to placing veneers on teeth. This step assures complete and passive
seating of the veneers, even in multiples.

11.Gently place the veneers on the tooth, preferably all at the same time, and tack in center
with small curing light perpendicular to facial surface, avoiding the margins. (The 3 mm
diameter Demetron tip is ideal and takes 2-3 sec to spot cure.) After tack has fully cured, cure
the other margins for about 1-2 seconds. Remove the resulting "jello" using a curette. Slide a
metal matrix band mesial and distal of one tooth at a time and cure. The metal bands should be
placed at the mesial and distal contacts of each tooth individually, preventing difficulty due to
additive thickness of more than two bands at a time.

To be avoided is placing a matrix prior to placing the veneer on the tooth. Pressure from the matrix
will push on the veneer, forcing compensating seating pressure which results in broken veneers.
If absolutely necessary, plumber’s teflon tape makes a good matrix.

12.Cure the entire veneer fully (slowly at first) with the matrix bands removed. Avoid high
intensity lights such as PAC lights unless you desire the look of "characterized", cracked veneers.

13.Finish gingival margin resin flash with a "new" twelve fluted carbide bur (usually a 7901),
if necessary, and finish interproximal with G-C New Metal strips 600 grit (GC Dental). For the
gingival margin areas, Danville’s Stainbuster (Flashbuster) also works very well to remove any
excess composite with no risk of damage to the veneer.

14.Polish exposed margins using thin, flexible polishing discs. Diamond "Flexis" disks (Vident)
work well when it is necessary to trim or reshape the porcelain. Use rubber porcelain

polishing cups/points such as Brasseler's "Dialite" cup and wheel to polish the porcelain.
