Implementation of laminate is a very successful technique that is used to modify some problems of front (anterior) teeth. Laminate is fundamentally different from crowning.  Dentists make a crown when most part of tooth has been destroyed. The most common case is after root canal therapy, but it's not the same when laminating. Laminate is a very thin layer like artificial nail that is placed on the tooth. Dentists have to reduce the tooth about 2 mm when crowning  to provide enough space for crown. However, when implementing laminate, the tooth structure is not reduced and this point is of great importance for dental health.


1. Direct (with composite structure)

2. indirect (with a structure made of porcelain)

Both methods have their advocates and dentists choose one of them based on individual conditions.

Type one- direct (with composite structure), this method can be done in one session and the used substance is called composite.

This substance is added layer after layer on the teeth to establish the proper form of tooth. The advantage of this method is

modifying  problems immediately in the office.

Type two- indirect (with a structure made of porcelain). This method is implemented in 3 sessions. The first session is reducing and

casting; the second session, laminate test; and the third session, cementation. Of advantages of laboratory type is spending short

time for each person in the office. But the entire process from casting to delivering takes one week. The structure of the second

type is of porcelain, made in the lab and applied on the tooth.

In the second type, modifying of laminate problems is performed in the lab. the first one has a lot of advocates because it will be

done in one session.


Performed samples in Dr. Mehdizadeh's office:

1. Modifying front teeth crowding ( in one session without reduction and crowning)

2. Modifying height of teeth in relation to each other (in one session without reduction and crowning)

3. Modifying the distance between the front teeth (in one session without reduction and crowning)

4. Modifying front teeth discoloration (in one session without reduction and crowning)

5. Modifying upper and lower teeth relation (in one session without reduction and crowning)

6. Applying missing teeth (in one session using FCR)

7. Changing the shape of tooth to another (in one session without reduction and crowning

The above image is an approximately 35-year old patient who didn't miss his right milk tooth which is marked with a red dot and in

the opposite side after central incisor tooth is the canine tooth (black dot) and the lateral incisor tooth has been removed. In the

right image, milk tooth (red dot) and canine (black dot) have been become lateral incisors.
