A veneer is a thin restoration placed over tooth surfaces to improve aesthetics or protect damage. Veneers have a translucent quality giving a natural look. Tooth preparation is minimal, reducing enamel by 0.3-0.5mm with a close finish line. Impressions are taken and a try-in ensures proper fit before cementing. Follow-up appointments evaluate tissue response and margins while maintaining good oral hygiene protects the veneers. Bonding uses a micromechanical bond with hydrophilic resins to cement the veneers securely in place.

3. A veneer is a thin layer of
restorative material placed over
a tooth surface, either to
improve the aesthetics of a
tooth, or to protect a damaged
tooth surface.
It has a translucent quality
which means that they give a

17. Tooth preparation:

18. Keep in mind…
• Lengthening the tooth
requires special attention
during the preparation stage.
• The occlusion , especially the
anterior guidance, should be
very carefully evaluated.
• Palatally finishing preparation
lines can be applied and in

19. minimal and limited to enamel
of tooth.
-The enamel should be reduced
by 0.3-0.5 mm in a
conservative intraenamel
preparation.
-The finish line should be as
close to the gingiva as possible
, or slightly sub-givgival.
- However, no matter what the
condition is, cervical
preparation is essential to
display the laminate's normal

21. Enamel has different
thicknesses at the
gingival, middle and

facial surface of the

23. There are two basic techniques for the placement
of the incisal finish line;
1)The first terminates the
prepared facial surface
at the incisal edge.
* There is no incisal reduction or
prep of the lingual
surface and it can be in the form
of a window or

24. (2) In the second
technique, the incisal edge is
slightly reduced and the
porcelain overlaps the incisal
edge, terminating on the
lingual surface.
* In a retrospective clinical
evaluation the two techniques

25. -Reduction

- To correct an uneven
finish line,
ensure that the diamond is

26. - Examination of the prepared
teeth is necessary.
-The dentist must be careful to
remove any sharp angles.
-Smooth margins that are fully

28. -The retraction cord should be left
in place if possible during the
impression.
-Use a polysiloxane or polyether
material for the impression
- Or we can use A polyvinyl
siloxane impression material to
take a full arch impression.

29. -The tray is seated and the
material was allowed to set
completely before it’s
removed from the patient’s
mouth
-The opposing arch
impression is also taken in
a polyvinyl material
-A hard-setting occlusal
registration was taken bite

30. The veneers should first be tried-in
before they are
bonded to eliminate unexpected
surprises.
When the patient arrives for the final
appointment.
what to do :
- First anesthetized for the
comfort of the patient.
_ Clean with flouride free

31. -Frist do good isolation.
-Sparated with soft matrix strip.
-Etche 15 to 30 sec with 37%
phosphoric acid.
-Applied Boinding agent.
-Put thin lyer of luting agent.
-Apply veneer slightly without force.
-Excess cement is removed.
-Partial curing for 5 to 10 sce.
-Aemove of all excess.
-Veneer should be cured from
all directions for at least

33. 1.Initial follow-up :
-Scheduled one week postcementation to evaluate tissue
response and margins,
-At 3-4 month intervals.
2.Clean it by brush and floss every
day for good oral hygiene.
3.Avoid using vertical strokes
during scaling,
4.Avoid the use of acidulated

34. Bonding of laminate
