Please read below in order to understand the process of placing veneers on your teeth
Before I start to correct a problem such as these separated and flared teeth, I want to analyze the position of the teeth, lip line and asymmetries are also taken into consideration.
I want to know where I am going with this case, and that in fact I can accomplish what my patient desires and what I promise to do. .
In order to get a preliminary idea of what our patient can look like, I send an image to my lab, to create a "Photoshopped" image of our patient.
This is only a two dimensional rendering of what we hope to accomplish. We design our case on the 3 dimensional impression model.
The sixty-four thousand dollar question, is... Can we do this with the real teeth? In all four dimensions?? Time is important also, it has to last.
Here is an idea of the planning that goes into a relatively simple case. These directions were given to my lab so they would comply with my plans.

OK here is a wax model of what my lab tech came up with. These are the pictures that were sent to me for approval. If I wanted to make any changes in the design, I can nowtell him to make these changes.
I decide now on the shade of the porcelain to use. In this case the patient has relatively light teeth. As we were correcting only four teeth, a major change of shade would look unnatural, and not pleasing.
A word about shade of teeth:
• The position and form of teeth is more important than the shade of the teeth.
• It is important for teeth in an arch to match, upper and lower teeth can be somewhat different in shades withoutlooking strange.
• Porcelain crowns and veneers do not lighten with bleaching procedures, nor do they darken with time.
With a guide made from the wax up model, the teeth are prepared (dentist's euphemism for drilled). The idea is to take away enough tooth structure to make room for the porcelain that will be covering the teeth, and for enough thickness to block out discoloration ( not an issue for this patient).
At this point an impression of the prepared teeth is made, and the case is sent to my laboratory. Temporary veneers are placed over the prepared teeth, and the patient is finished with the preparatory visit.
Ten days later, I am sent pictures of the completed veneers. Again, if there is something I need to change or correct, this is the time.
The Big Day
Finally the big day has arrived. The temporary veneers are removed and the teeth are isolated with a rubber sheet so as not to allow moisture contamination from the mouth during the bonding process.
The teeth are cleaned, desensitized and prepared with special materials for the bonding process.
Immediately after the bonding process, the gums are a little scraped from the removal of the bonding cement.
We are done!
Two weeks later the gums have healed nicely. The gums have accepted the porcelain, as they exhibit no redness or swelling.
I check for any extra cement that may have been left and make sure that the patient is comfortable.
