Veneers are a conservative treatment to improve the appearance of teeth. They involve bonding thin facings of tooth-colored material to the front of teeth. Veneers can be made of composite resin, porcelain, or other ceramic materials. They are either bonded directly during a single appointment or indirectly with impressions taken and veneers fabricated by a dental laboratory over two appointments. Veneers can repair damage, close gaps, change the shape or length of teeth, or improve discoloration while minimizing the removal of tooth structure. The choice of material and technique depends on the specific needs and preferences of the patient.

4. Definition
• A veneer is a layer of tooth-colored material that is applied to a tooth to
restore localized or generalized defect and intrinsic discolorations.
(Sturdevant's art & science operative dentistry)
typically, veneers are made of directly applied composite,
processed composite , porcelain, or pressed ceramic materials.
4

5. Indications
• Improve extreme discolorations such as tetracycline staining,
flourosis, devitalized teeth, and teeth darkened from age.
• Repair chipped or fractured teeth.
5

6. • Closing of diastemas between teeth.
• Ability to lengthen anterior teeth.
• Improve the appearance of rotated or misaligned teeth
6

7. Contraindication
• If little or no enamel is present, full crown should be considered.
• Certain tooth-to-tooth habits like bruxing or clenching, or other para-
functional habits such as pencil chewing or ice crushing.
• Teeth that exhibit severe crowding.
• Certain types of occlusal problems such as Class III & end-to-end bites
• Poor oral hygiene.
• High caries rate.
7

8. Types
Based on extent of tooth involved;-
1.Partial veneers
2.Full veneers
• Partial veneers are indicated for the restoration of localized defects
or areas of intrinsic discoloration.
• Full veneers are indicated for the restoration of generalized defects
or areas of intrinsic staining involving most of the facial surface of
the tooth. 8
Window preparation
Butt-joint incisal preparation
Incisal lapping preparation

9. • Two basic preparation designs exists for full veneers:
1. Window preparation:
2. Incisal, lapping preparation
1. Window preparation:
• it is recommended for most direct and indirect composite
veneers.
• This intraenamel design preserves the functional lingual and
incisal surfaces of the maxillary anterior teeth, protecting the
veneers from significant occlusal stress.
• By using a window preparation,the functional surfaces are
better preserved in enamel.
9

10. 2.Incisal-lapping preparation
• It is indicated when the tooth being veneered needs
lengthening or when an incisal defect warrants restoration.
• This design is used frequently with porcelain veneers
because it not only facilitates accurate seating of the veneer
on cementation ,but it also allows for improved esthetics
along the incisal edge.

14. composite veneers
Advantages
•One visit procedure
•Less expensive
•Repair potential
•Chair-side control of the anatomy
•Minimal irreversible loss of tooth structure.
Disadvantages
•Tend to discolor
•Wear out quickly
•Marginal staining
•Shade matching difficulty
•Often require repair and replacement
14

15. • Very conservative.
• Offer better inherent color and natural look.
• Tissue tolerance is excellent.
• Less staining.
• The bond of etched porcelain veneer to
enamel is stronger than other.
• Wear and abrasion resistance is high.
• The aesthetics are better than any other
veneer material.
• Porcelain veneer allow transmission of light.
•Expensive.
•Tooth preparation.
•Highly sensitive technique.
•Sensitivity.
• It has number of limitation
15
Conventional Porcelain Veneers:

16. • When only a few teeth are involved, or
when the entire facial surface is not
faulty (i.e., partial veneers), directly
applied composite veneers can be
completed chair side for the patient in
one appointment.
• Indirect veneers require two
appointments, but typically offer three
advantages over directly placed full
veneers, as follows:
16

17. 1. Indirectly fabricated veneers are much less sensitive to operator
technique. Indirect veneers are made by a laboratory technician
and are typically more esthetic.
2. If multiple teeth are to be veneered, indirect veneers usually can
be placed much more expeditiously.
3. Indirect veneers typically last much longer than direct veneers,
especially if they are made of porcelain or pressed ceramic.
17

18. Direct veneer techniques
• Are indicated for the restoration of localized defects or areas of intrinsic discoloration
• These defect can be restore in one appointment with light-cured
composite.

21. Indirect veneer technique
• Indirect veneer are made of
1. Processed composite
2. Feldspathic porcelain
3. Cast or pressed ceramic
• Two appointment are required

• One visit procedure
• Less expensive
• Repair potential
• Chair-side control of the

• Minimal irreversible loss of tooth

• Porcelain Veneers
• Esthetic stability
• Stain resistant
• Stronger and durable
• Gum tissue tolerates porcelain
well
• The color of a porcelain veneer
can be selected such that it
makes dark teeth appear whiter.
• Veneers offer a conservative
approach to changing a tooth's
color and shape.
22

23. Processed composite veneers
First Appointment
*Window preparation recommended due to limited bond strength.
*Incisal lapping if incisal defect.
*Intraenamel preparation.
*Elastomeric impressions.
*No temporization.
23

24. 24
Second Appointment
Evaluate fit of veneer.
Tooth side of veneer (pre etched) is primed.
Tooth etched, rinsed and dried. Adhesive is applied but not cured.
Adhesive cement applied.
Veneer placed and excess cement removed.
Light cured for 40-60sec facial & lingual.*
 Check for fit with no.2 explorer.

25. Etched porcelain veneer
A Etched porcelain veneer is a thin piece of porcelain that is bonded
to the front of a tooth. Porcelain is a durable, translucent, strong,
natural-looking, and beautiful material.
The only difference in this procedure for porcelain veneers from the
composite veneers is the need to condition the internal surface of
each veneer with a silane primer just before applying the resin-
bonding agent

27. • Labial reduction - Interproximal reduction
• Incisal modification - Cervical definition
• Place a horizontal facial depth cut, it is usually 0.3 mm from
proximal line angle to proximal line angle. Make this depth cut at
the junction of the cervical and middle one-third of the facial
surface of the tooth.*
• Paralleling the entire gingival margin, prepare a definitive
chamfer finish line.
• Continue the definitive chamfer finish line with diamond bur from
the papilla tip toward the incisal edge on both the mesial and
distal proximal surfaces.
• The facial depth cuts are removed with the diamond bur, and
the long axis of the diamond bur is “rolled” into the proximal
chamfer area to eliminate any sharp line angles 27

Apply cement to the
internal aspect of the
veneer, seat the veneer,
clean off excess cement,
light cure
Floss contacts and
adjust occlusion.

33. Lumineer
Difference between Lumineers and standard porcelain veneers
• The main difference is that Lumineers are made from a special
patented cerinate porcelain that is very strong but much thinner
than traditional laboratory-fabricated veneers. Their thickness is
comparable to contact lenses.
33

34. Advantage
• Lumineers can be placed on the teeth without removal of the tooth
structure.
• Patients can receive their veneers quickly, usually within two weeks
from the date that the impressions are made.
• Lumineers bond directly to the tooth, making the bond very strong. They
are also very long-lasting- up to twenty years or longer.
• Lumineers are a reversible procedure.
34

35. The LUMINEERS Minimal
Contouring Technique
• requires slight modification of the enamel but never touches dentin
during LUMINEERS placement. Only0 .3 mm-0.5 mm enamel is
removed, causing no sensitivity for the patient and therefore no
need for any anesthesia.

39. Conclusion
• This procedure is becoming more common in dental offices
because everyone want a great smile.
• It is a great way to change a smile that shows yellowed, stained
teeth into one that make you look fantastic.
• But remember veneers are not for everyone, & if your teeth are
not strong enough you will not be recommended to have the dental
veneers applied.
