Not only meeting the esthetic expectations of the patient but also long term structural, functional and biological success is very important for both your dentist and technician. Making teeth that will look natural is not only about the color. They are made taking color tone, saturation, brightness and translucence into consideration. Pale and opaque looking the teeth make patients think translucence of the teeth is insufficient. The dentist pays attention to several parameters. The cutting edges of the teeth and their structures are very important. It is very important to conduct a color analysis for both porcelain teeth and partly laminated teeth. First we choose a primary color. Color saturation, brightness and translucence of the teeth are evaluated afterwards. If the color value of the teeth is not compatible with the other natural teeth, it will be easy to see they are artificial. Inconsistencies in other areas can only be distinguished by a dentist. There are some differences in porcelain laminated teeth. The most important point to consider is to avoid excessive corrosion and leaving even a little enamel tissue under the lamination. This is important to get a more natural look as the enamel reflects light.
Porcelain Laminate Veneers
Laminate porcelains are very thin ceramic materials we especially use on anterior teeth. They are largely used for patients that are not satisfied with the color of their teeth or have broken, abraded, overlapped teeth, as well as patients with diastema. The most essential property of the application is the preparation of the teeth by abrading approximately 0.5mm of the surface. How can such a thin and fragile slice of porcelain have such a strong structure? laminate porcelains show the same physical characteristics as tooth enamel after it is laminated onto teeth. Practices such as the abrasion of the teeth, taking measurements, production and the application process of the laminates are prepared and carried out very meticulously. If not, patients may experience negative outcomes.
Laminate Porcelains Are Suitable For
Your teeth are whitened via one of two methods although these methods can sometimes be used together in some cases.
Plasma (Light) Bleaching
The bleaching procedure conducted under the supervision of your dentist in a clinical environment is called office bleaching. In this procedure, a transparent bleaching gel is applied to the surface of your teeth and the crystals in the bleaching gel are activated with the use of an intense source of light. The crystals in the transparent bleaching gel absorb the light's energy and penetrate into the enamel. This is how the bleaching process begins. The bleaching gel used in office bleaching contains hydrogen peroxide. In office bleaching, light is used to activate the hydrogen peroxide rapidly.
Prepared according to the measures taken from the patient, plates are used at home for approximately 2 hours a day. You apply the amount of bleaching gel your doctor recommends onto the front surfaces of your teeth and position the plate in your mouth. After 5 or 6 daily uses, you get the intended result. With the home bleaching method, you may not be able to bleach lifeless teeth darkened by root canal treatment. You may not get results for tetracycline stains because of the concentration of the bleaching gel is low in order to protect your teeth or gums. The active ingredient of the bleaching gel used in home bleaching is 10-16-22 % carbamide peroxide (CH4N2O2). Carbamide peroxide is found in white crystals that produce hydrogen peroxide when they come into contact with water.
Dental composites are made of silicon dioxide, quartz particles and synthetic resin fillers. Composite bondings are made to different forms, solidities, translucencies and colors. They are ideal for repairing broken anterior teeth. They are also used for filling gaps between teeth, filling eroded tooth surfaces and extending the tooth length.
Non-Metal porcelain crowns
There are many non-metal porcelains in current use made from zirconium or alumina. Your dentist decides on which non-metal porcelain to use after your examination. Zirconium teeth are prefered for the posterior teeth as they are durable and provide an esthetic look whereas other non-metal porcelain structures are prefered for the anterior teeth. Zirconiums have a durability degree of 900-1400 MPa whereas metal porcelains are durable approximately up to 800 MPa or less. The use of zirconium is also common for 3-4 unit bridges. As they have the same color as your teeth, you will not see gray reflections in the gum area.
Metal porcelain crowns
These crowns are used if there is tooth decay under the gums, too much enamel loss or if your teeth are broken. There are two types of crowns; metal and non-metal. Metal crowns are used largely on the posterior teeth due to grey reflections that can be seen on the gum line and their opacity. Non-metal porcelain restorations are mainly called esthetic porcelains. Metal crowns reflect light shattering the feeling of depth and vitality. However, dentists have been able to make very thin metal porcelains via the spray process recently. Metal porcelains are more affordable compared to other porcelains.
