PORCELAINE LAMINATE VENEERS Flashcards
WHAT IS A VENEER ?
DEFINITION:
▸ GPT8: It is a thin bonded ceramic
restorations that restore the facial surface
and part of the proximal surfaces of the
teeth requiring aesthetic restoration.
▸ — is the key for the long term
success of the restoration.
Enamel Bond
ADVANTAGES OF PORCELAIN VENEERS:
(5)
▸ Conservative approach
▸ Biocompatible
▸ Esthetics and patient satisfaction
▸ Color stable
▸ Resistance to abrasion
DISADVANTAGES
▸ Technique sensitive “—”
▸ — chairside (temporizing and cementation)
▸ Requires skillful —
▸ — is difficult to be modified after fabrication
▸ Hard, if not impossible, to —
▸ — to handle
▸ — v/s composite veneers

HOW LONG DO VENEERS LAST?
▸ 10-years estimated cumulative rate of Porcelaine Laminate Veneers (PLVs) was
95.5%
(4) were
considered as reasons for restoration failure
Fracture, debonding, occurrence of secondary caries, and need of endodontic treatment
— seems to be most common complication of PLVs, followed by —, both more
commonly happening within the first years after PLV cementation
Fracture
debonding
PLVs with incisal coverage and non-feldspathic PLVs presented lower failure rates than
PLVs
without incisal coverage and feldspathic PLVs, respectively.
ESTHETIC CONSIDERATIONS AND CASE SELECTION
(4)
▸ Smile analysis
▸ Teeth shape and proportions
▸ Occlusion
▸ Color and shade selection
SHADE SELECTION SHOULD INCLUDE:
(5)
▸ Check lighting condition, use natural light.
▸ Remove destructive color such as lip stick from shade taking field.
▸ Take tooth shade before procedure, keep tooth wet, do not dehydrate.
▸ Remember to take the stump shade.
▸ From straight angle to the tooth, quickly select several possible shade tabs then
select one.
