WHAT ARE PORCELAIN VENEERS

• Porcelain veneers are extremely thin porcelain
  shells that have the thickness of 0.5 mm, and
  which are applied on the tooth in order to attain
  aesthetically satisfactory smile.
• They are used to cover labial surfaces of chipped
  or discolored teeth.

ARE YOU A PORCELAIN VENEER CANDIDATE?

• Patients who would like to have veneers applied
  have to have healthy and strong teeth.
• Porcelain veneers are mostly used in cases of
• Discolored teeth (ex. Tetracycline teeth)
• Unshapely teeth
• Lightly misaligned teeth
• Small gaps in-between teeth
• Worn and chipped teeth

APPLICATION PROCEDURE

• Three visits to the dentist are required
• During the first visit, the dentist should
  explain the patient the nature of veneers and the
  procedure for their application, including all
  benefits and disadvantages.
• The second visit is used for preparation
  activities, i.e. taking impression of the teeth.
  This activity requires the use of long, thin and
  cylindrical burs.

5

• The preparation procedure involves elimination of
  the vestibular part of the tooth in depth of 0.6
  1 mm.
• Approximate points are not to be scraped, but
  provided they are, then scraping should be
  extended obliquely.
• Provided that scraping is painful to the patient,
  it may be done with the help of local anesthesia.
• As soon as preparation activities are completed,
  teeth impressions may be taken.

• Since only a small part of the labial area of the
  tooth is scraped off, most cases dont require
  temporary restoration.
• The impression is then taken to the laboratory,
  where the veneers are made in a period of several
  days to a week. Veneers are made of metal-free
  ceramics (Empress-2 on Ivoclar- Vivadent )

• The veneers are applied on the third visit to the
  office. After the initial fitting they are
  cemented to the teeth. The teeth are first
  cleaned with polishing paste and then brushed.
  Cementing is carried out by using cement with the
  same color of the teeth. It may be regular or
  photopolymerisation one. (Ivoclar- Vivadent)
• The applied veneers are durable and resistant to
  the pressure caused by mastication.

• Still, patients should avoid chewing bones and
  taking big bites of hard food, since this may
  cause damage to the veneers or even dislocate
  them.
• Patients should take care for the veneers as if
  they were their natural teeth.

ADVANTAGES OF PORCELAIN VENEERS

• Veneers are the newest alternative for patients
  in search for a perfect smile. Since they are
  strong, they can last for a very long period of
  time with the proper care. Veneers allow patients
  to get white teeth without the fear of
  discoloration.
• The short period of creation and application is a
  great advantage.
• Veneers require no special or greater care other
  than that of natural teeth.
• A beautiful smile is very attractive.

14
DISADVANTAGES OF PORCELAIN VENEERS

• Patients need a period of one to two weeks in
  order to adapt to the new color, shape or size of
  their teeth.
• Sometimes there is a need for a fourth visit to
  the office in order to control the reaction of
  the teeth and gums to the veneers.
• Reaction to changes in temperature is plausible,
  but it fades away within a week.

15
EXAMPLE

• A 30 year old patient, who had a strong teeth
  discoloration as a result of tetracycline
  therapy, desired a better appearance of his
  teeth. A decision was made that porcelain veneers
  are the solution to his problem. The challenge
  that this case brings is to cover tetracycline
  teeth and acquire a beautiful smile.
