What is Crown?
Crown is the only part of teeth that we can see from the outside anatomically. Even though it’s known as a way of crowning, it actually stands for a part of teeth. The crown’s shape gives us information about the function of the teeth. For example, incisor teeth are for disrupting the food and for that they’re in scalpriform, as for molar teeth, they have flat surfaces for grinding up.
What is Crowning?
Crowning is a way of treatment used for covering teeth which are broken, deformed or discolored for various reasons. It has a very durable structure and that’s why it gives the nearest results against high biting pressures compared to original teeth. The crown is more likely to lose its visual and functional qualities as it’s the first part of teeth to contact with food. That is why crowning is an ideal way to make this visible part retrieve its functions.
What are the kinds of Crowning?
Porcelain Crowning are stable prosthetics prepared and pasted in a laboratory environment as a bridge with shrinking adjacent and supporting teeth, or to remove cavities or discolorations in a single or a few teeth. Even though these prosthetics that are applied to the visible part of teeth and unremovable by the patient itself are more useful than removable ones, there are some conditions that are looked for in a patient. The patient gets informed of those conditions by the dentist.
Procedure can take place in 3-4 sessions which is spent with measuring and preparing the teeth, in other words, a week.
In which situations can Porcelain Crowning take place?
• Excessive matter loss on teeth and cavities,
• On discolored and irreversibly discolored teeth,
• On deformed teeth
• On weak teeth which got a root canal treatment
• On implant procedures,
• To repair broken teeth
What are the functions of Porcelain Crowning?
Besides empowering the damaged teeth, Porcelain Crowning can also be used to fix the shape, proportion and alignment. In old-style treatments, porcelain crowning that have metal infrastructure were also used to make sure that porcelain crown with the original color of the teeth was strong. As for today, ‘full porcelain’ and ‘laminate’ which reflect light better are used in frontal parts to provide an aesthetic smile and porcelain which have zircon supported metal infrastructure are used in rear teeth.
What are the types of Porcelain Crowning?
The type of porcelain that is going to be used in the treatment is determined by the doctor suitable to the patient’s mouth structure and the damage on its teeth. In these crowning, the durability of metals was used as infrastructure and the aesthetic of porcelain was used as superstructure. Even
though porcelain crowning produced with this method are still used, stable prosthetic applications made from very particular materials which can imitate the natural outlook of the teeth are among treatment procedures that are used.
These treatments below can take place according to their location in the mouth, number of lost teeth, the patients’ needs and the dentist’s procedure techniques;
• Metal supported porcelain crowning,
• Zirconium supported porcelain crowning,
• Full ceramic crowning,
• Full ceramic or composite laminate crowning,
• Metal Supported Porcelain Crowning
The inner part of the infrastructure of metal supported porcelain crowning is metal. Metal gets shaped into teeth and gets covered with durable porcelain. However, these aesthetically high-quality product can cause compliance and naturality problems related to its luminous transmittance.
• Zirconium Supported Porcelain Crowning
Zirconium supported porcelain crowning is one of the most aesthetically advantageous procedures by having the proximate luminous transmittance to the natural teeth. Zirconium crowning, destroys the risk of allergies, forms a healthy harmony with gum and is a much more aesthetic solution than metal supported ceramic crowning with these features. Moreover, it doesn’t cause a luminous transmittance problem like metal supported crowning thanks to its white color.
• Full Ceramic Crowning
Full ceramic crowning is aesthetically the best crowning and used particularly on foreteeth. It’s nearly impossible for them to leave natural teeth. As for its luminous transmittance, it is rather high because it doesn’t consist of a non-transparent structure like metal or zirconium crowning. The amount of matter getting removed from the teeth surface decreases related to these crowning being less thick than others. This is another advantage of ceramic crowning.
• Ceramic or Composite Laminate Crowning
Ceramic or composite laminate crowning are aesthetic procedures which take place by etching teeth a fair amount from only their visible frontal surfaces, in short, as thick as 0.3-0.7mm. While composite laminates can take place in a single session on the patient chair, ceramic laminates get prepared in a laboratory environment by technicians before the session after the measurement process, just like other crowning. Ceramic laminates are much more aesthetically successful compared to composite ones because they are made from porcelain.
