Everyone once in a lifetime has faced the loss of a tooth. In case of that happening this tooth needs to be replaced as soon as possible. The absence of the tooth may cause adjacent teeth to bend, fall out, making problems for the jaw, the way we bite, loss of other teeth. Luckily prosthetics help us to deal with these problems- It’s an artificial renewal of the lost teeth. If the defect is not limited( teeth are missing at the end of the row), then removable dentures must be made from acrylic (plastic), Valplast flexible dentures or circular dentures.
If the defect is limited ( there are teeth in both sides of missing tooth). Then non-removable denture may be made. It is a bridge that is based on adjacent teeth, only they need to be grinded. Sometimes combined dentures (removable and non-removable) are made. Combined dentures are made when hard and complicated prosthetic operation is necessary. Modern dentistry also allows to replace missing teeth with dental implants! If implants are to be used to replace the missing tooth, other teeth remain untouched. What kind of treatment is necessary is up to dentist to decide.
After careful diagnostics, treatment plan is made and is offered to the patient. Patient chooses what is best for him after dentist explains the different ways situation could be dealt with. Before doing prosthetic manipulations It is recommended to have a healthy oral cavity. So that you gain esthetic, qualitative and lasting result. Oral hygiene is very important because teeth may be damaged if dental hygiene is poor.
Short introduction to different types of prosthetics
Ceramic onlays or inlays are like dental sealants which are made in dental laboratory, based on your teeth. After It’s made dentist glues it to the walls of the tooth. These sealants are much more stronger, do not change in color, do not decay over time and are esthetic. Usually they are made on the side teeth.
Ceramic veneers can be used to make front teeth sealants invisible, make the tooth look more pretty. They are small thin almost transparent plates, which are glued to the front teeth enamel. They surprise with their natural look and great esthetic effect. They are very smooth and do not loose their functional abilities over time and do not change in color.
Dental crowns can be made from different sorts of materials (e.g., Zircon, Ceramic, Gold or other metal alloys). Dental crown is put on an existing tooth, if it is heavily damaged or changed in color, or it is the basis of a bridge.
Dental plate- type of prosthetics which is applied when there is no teeth in jaw or there is a non-limited defect. Plastic teeth look so natural that It is really hard to tell that one has fake teeth. Plastic base fits the gums perfectly. Only disadvantage to these dentures is the uncomfortable feeling, when one starts to wear them and the need to adapt to this change.
Circular dentures- they unlike dental plates contain metallic frame and clasps. It allows to minimize prosthetic base. Some time ago it was not possible to cover the clasps for dentures. Now there are different fixation elements that satisfy esthetic needs.
Pressed ceramic crowns
If patient has high esthetic requirements for a crown, which does not have a huge load, then pressed ceramic crowns can be used . It is nearly impossible to see the difference between this crown and a natural tooth. Ceramic is bioinert material, that does not harm the human body. Any needed color can be chosen for this crown. Ceramic is good at catching light and reflecting it, that is why It looks natural. In addition it is very durable, because of the modern technology used to make these crowns.
Advantages of pressed ceramic crowns:
✔ They look great
✔ The color and the crowns themselves are very durable
✔ The gums do not color as in cases with different crowns
Exclusive ceramic on Zircon oxide base – in modern dentistry is popular in America and Europe.
The popularity of Zircon alloy is easy to understand:
✔ It has the natural color of teeth
✔ Great esthetic result (veneers)
✔ Absolute safety and durability ( especially side teeth)
Zircon dioxide- new technology material, which is used in space ships and in medicine.
Uses in dentistry:
✔ Separate crowns
✔ Bridge type dentures
✔ Prosthetics on dental implants
Unique Zircon properties
Zircon oxide ceramics have high esthetic quality because:
Cirkonija oksīda keramikai piemīt augsta estētiska kvalitāte pateicoties šādiem faktoriem:
✔ For the first time a color can be chosen not only for ceramic overlay but also for the crown itself. Which makes it possible to avoid transparency effect of metal.
✔ It allows light to easily shine on teeth making them look very natural, like a perfect copy of a natural tooth.
These factors help to make crowns which look the same as natural teeth. And there is no blue gum effect, which usually appears after using metal-ceramic crowns.
High durability is achieved by microstructural change using Yttrium oxide.
High durability gives the chance to:
✔ Create crowns and bridges for up to 4 units in frontal or side teeth.
✔ Make crowns on dental implants.
✔ Zircon oxide crowns are lighter and need lesser grinding than metal-ceramic crowns
✔ Exclude galvanization effect completely because there is no metal elements in mouth
✔ Crowns protect the teeth from hot and cold and It is not that sensitive
✔ Crowns are not allergic, they are bio-compatible
Zircon oxide crowns are truly safe and esthetic!
To renew the form of the tooth, to strengthen the tooth or make it look better. Usually crowns are put on broken, damaged teeth. First thing that must be done is taking the dental impression of the tooth. Later It is sent to dental lab to make a crown trough a complicated process.
Metal-ceramic crown- it is the combination of a metallic frame with ceramic overlay. These crowns are usually put on heavily damaged side teeth, rarely on the front teeth. To make such a crown first metallic frame must be made, which precisely fits the tooth. Frame- the most important part in the construction, that is why to achieve maximum quality , it can be made from precious metal alloys ( e.g., gold, platinum, Zircon oxide or Aluminum oxide) or titan alloys or Chrome-Cobalt alloys. Making a crown is hard work it is hand-made and requires a lot of specific knowledge. This kind of crown has high durability and it is esthetic.
