Dental crowns are fixed dental replacements placed on a single tooth or a tooth implant in order to cover the tooth crown. Due to the use of high-quality materials and premium performance, they provide a completely natural appearance of the tooth, which meets the highest aesthetic criteria.
The tooth is covered with a ceramic crown when the dentist evaluates that the tooth is so damaged that the filling cannot resolve the problem of shape, functionality and aesthetics of the tooth. Crowns can be metal-ceramic, zirconium-ceramic or completely ceramic. They are often used for replacing teeth whose surface was damaged by deep caries, or endodontically treated teeth which may have extensive fillings or discoloration after treatment. In endodontic treatment, before the placement of the crown, the tooth is additionally reinforced by a composite suprastructure in order to achieve the desired strength.
Zirconium-ceramic crowns are intended for clients who strive towards premium quality and aesthetics, and modern technology enables computer scanning and making of a zirconium base, and impeccable precision of crown edge performance. The white colour of its base truly replicates the natural teeth and rectifies any aesthetic defects.
We recommend the use of glass-ceramic crowns to the patients with a special flair for aesthetics, particularly E.max ceramics (manufactured by Ivoclar Vivadent). Since both the placement technique and the manufacture of this ceramic crown are extremely demanding, the dentist and the dental assistant are required to undergo a special training and be very skilled at colour manipulation, and have excellent knowledge of optical properties of teeth and the material itself.
Before you decide on a specific type of material, you have to bear in mind that the crowns made entirely of ceramics are a much prettier and better alternative to classic metal-ceramic varieties. This is because they allow natural translucence and penetration of light through the tooth and the crown, which results in a completely natural appearance of your dental replacement.
Unlike the crown placed on a single tooth, the bridge is the solution for a partially toothless jaw, because it replaces one or more missing teeth, depending on the position of supports in the form of your teeth or implants.
Traditional dentistry uses metal-ceramic crowns made of different materials such as gold-platinum alloy, cobalt-chromium-molybdenum alloy or nickel-titanium covered with aesthetic ceramic coat. These crowns are ideal for covering the back teeth which are largely susceptible to substantial masticatory forces.
A female patient had metal-ceramic bridges in the upper jaw, and wanted to replace them. We opted for zirconium ceramics whose aesthetics is ideal for the frontal region, whereas its strength and resilience support wide span bridges.
A young female patient, who works in a line of business where teeth are extremely important, arrived to our dental office with two prominent metal-ceramic crowns of darker colour and irregular position on the upper left incisors.
The patient needed a fast smile makeover, and we did not have time for orthodontic treatment, so we placed completely ceramic crowns of lighter colour in a regular line on all upper teeth. In order to achieve the red-white aesthetics, which is an indispensable factor in a beautiful smile, we performed gingivectomy.
The patient did not want any changes on the lower jaw teeth, and since there were gaps between them, we shaped the upper crowns to match the lower ones.
A male patient has old completely gold dental crowns, and missing teeth in the upper right segment. We achieved a major change in his appearance by placing metal-ceramic crowns and a bridge to replace the missing teeth on the right side.
Completely ceramic crowns
A male patient is unhappy with his upper and lower front teeth. He is dissatisfied with the colour and the level of abrasion of his upper teeth, whereas he has a provisional fix on his lower teeth due to a large gap between his central incisors.
We used completely ceramic crowns of light colour to enlarge the upper teeth, and we placed a completely ceramic bridge on the lower teeth. The bridge unit has a part of red ceramics due to extensive bone loss in that region.
A female patient has old dental crowns with signs of gum retraction, which disrupted her tooth aesthetics and functionality. Other teeth are covered with worn out amalgam fillings which should be replaced.
We made her new metal-ceramic crowns in the upper jaw, and we replaced all amalgam fillings with composite fillings.
Completely ceramic crowns
A female patient has a bridge in the upper right jaw, whose colour does not match her natural teeth. Her natural teeth are extremely yellow, with many fillings.
In order to achieve the maximum aesthetic effect before performing a dental prosthetic replacement, we had to level the gums - gingivectomy. Later on, we placed completely ceramic crowns of lighter hue on all teeth.
Completely ceramic crowns
A female patient has worn out metal-ceramic on lateral upper teeth. She has old chipped fillings on the front teeth, and her teeth are abraded.
At this stage, we decided to place completely ceramic crowns on her upper teeth, because the patient chose the same treatment for her lower teeth.
A male patient had worn out metal-ceramic crowns on the front which were not aesthetically pleasing. The crowns seemed “too short” because of the uneven level of the gums.
After we surgically levelled the gums, we replaced the old crowns on the upper four incisors with completely ceramic crowns, obtaining thus a completely new smile and a very pleased patient.
A female patient was unhappy with her upper right lateral incisor, the colour of her teeth, and the missing teeth on the left side.
We placed completely ceramic crowns of lighter colour on all upper and lower teeth, achieving thus a more beautiful and younger appearance. We rectified the lack of teeth on the left side by placing a completely ceramic bridge.
