What are dental prostheses?
All the products made in a dental technician laboratory and consequently used by dentists for dental restoration of damaged or missing teeth are called dental prostheses. These include:
- Dental veneers (porcelain veneers)
- Dental onlays
- Dental crowns (ceramic crowns)
- Fixed or removable dentures
Existing Teeth Prosthesis – when a tooth is significantly damaged, decayed or has lost a larger part of the crown, it can be still saved by prosthesis.
Dental prosthesis is performed using veneers, dental on-lays or dental crowns (tooth crowns). It helps to restore the form, color and function of a tooth (or teeth in a row). Prostheses are made of bio-compatible (well tolerated in organism) materials: metal-free ceramics, zirconium ceramics, metal ceramics and other.

Dental prosthesis using veneers could be described as aesthetic front teeth restoration. Read here to find everything you need to know about cosmetic dental restoration with veneers.
If you lost more than 50% of the tooth tissue, dental filling is not enough to restore the damage. In such case, it is recommended to restore a tooth by using dental onlays – micro-prostheses used for restoration of damaged molars. Compared to composite fillings, they are more wear-resistant and last longer. Onlays are very thin, so the teeth are sanded only minimally. The materials used for onlays are normally: ceramic (porcelain), composite or a noble metal.
Ceramic crown – a natural tooth size, shape and color cap, which is put on and surrounds the affected tooth. Dental crowns are used to restore the damaged, worn out or endodontically treated teeth, as well as teeth which have changed their natural color. Crowns look and function as if they were natural – they do not stand out in a row of teeth and are strong enough to withstand the chewing load. Dental crowns are made of porcelain, metal or zirconia ceramics.
Before the prosthetics teeth are normally sanded – part of the surface of the tooth is removed. When the tooth is prepared, a dentist takes the prints of the tooth, according to which a technician manufactures a customized dental crown. The produced crown is then fixed to the sanded tooth.
Prosthesis using ceramic crowns
Can artificial teeth look like natural ones? Today, we say YES. This is so due to a new generation of ceramics. Our partner dental clinic works with dental technicians who ensure the highest quality of dental prosthesis. Your dentist will tell you in detail about all the possibilities, advantages and disadvantages of different materials in order to help you choose the best option. Here you will find information on the most popular types of dental crowns.
Read about Metal-free ceramics
Metal-free ceramic crowns bring the aesthetics to a whole new level. They are produced completely of porcelain, thus heir physical properties are similar to the ones of natural teeth. Such crowns seem very natural as they are permeable to light.
Benefits of a porcelain crown:
- Impeccable aesthetics and transparency (light-permeable crowns, so it seems as if they were natural)
- Crowns are made of a biologically compatible, non-allergic material
- Durability and wear-resistance
- Crowns perfectly fit to the tooth tissue
- The edge of a metal prosthesis is invisible
- Looks like natural gums (no blue colour, which is often the case with metal ceramic prostheses)
- No metallic taste in the mouth
The disadvantages of a porcelain crown:
- Only for the front teeth prosthesis (Metal-free construction is not strong enough to withstand the load of the molars)
- Prosthesis cannot be performed for more than three adjacent teeth
- High price of metal-free porcelain (much higher than metal ceramic)
Read about Zirconia ceramics
Zirconia ceramic crowns – very comfortable and durable porcelain dentures. Its frame is made of zirconium oxide, which is coated with porcelain.
The advantages of zirconia ceramic crowns:
- Especially strong (zirconia oxide is not metal, but very strong and resistant to fractures)
- Durability and wear-resistance
- Made of anti-allergic agents (metal-free construction)
- Aesthetics and transparency (light-permeable crowns, so it looks like natural teeth)
- Suitable for a single tooth replacement, as well as a dental row
- No metallic taste in the mouth
Disadvantages of zirconium ceramic crowns:
- High price of the zirconia ceramic (more than metal ceramic)
Read about Metal ceramics
The frame of metal ceramic crowns is made of metal, which is covered with porcelain coating. Metal ceramics is not transparent and permeable to light, so your teeth do not seem natural. Such prostheses are recommended for molars.
Benefits of metal ceramic crowns:
- Durability – a metal frame is especially strong;
- Prosthesis may be used for a single tooth replacement, as well as dental rows
- Lower cost (in comparison with prosthesis using metal-free porcelain crowns)
Disadvantages of metal ceramic crowns:
- Metal ceramics is not permeable to light, so your teeth do not seem natural
- Metals in the core of the crown can cause allergies
- You can see the metal edges of such crown
- A specific metallic taste can be felt in the mouth
The missing teeth can be restored with the help of the following:
- Fixed dental prosthesis (dental bridges)
- Removable dental prosthesis (partial or full)
- Dental Implants
The procedure of how the dental bridge is used instead of a missing tooth can be seen below:
|Missing a single tooth in esthetic zone|
|Usual bridge held by the adjacent teeth
The fixed dental bridge is used when one or few teeth are missing. Its goal is to stabilise the bite and prevent dental tilt (when a tooth is missing, the adjacent are moving to the empty space). Dental bridge requires the teeth, adjacent to the missing one, to be sanded and used as a support for it. This hurts the enamel of the healthy teeth and thus shortens their lifetime.
However, the procedure has flaws and thus dental implants are often seen as a more preferred option.
The procedure of how conventional removable dentures replace the missing tooth group can be seen in the image below:
|Missing a fewteeth at the end of a row|
|A removable partial denture (2 teeth)
|A removable partial denture (3 teeth)|
Removable partial dentures are used when there are few nearby teeth missing. They help to restore the biting function and aesthetic view of the mouth. The denture requires the teeth, adjacent to the missing one, to be sanded and used as a support for it. This hurts the enamel of the healthy teeth and thus shortens their lifetime. Also, the taste of metal may be felt in the mouth.
An alternative to removable partial dentures are dental implants, which in most cases are considered as more advantageous.
The simple illustration of removable dentures can be seen below:
|Toothless lower jaw|
|Removable dentures – common inflammation|
Such dentures are used when the jaw is toothless (or when the remaining teeth are not strong enough to hold the partial denture). Its goal is to restore the biting function and the aesthetics of the mouth. The pink rubber part holds the prosthesis in place; however does not provide full stability. Because of the little biting load, usage of this kind of dentures leads to the jawbone decay. Removable dentures need to be corrected from time to time, due to changing contour.
A modern and more advantageous alternative to full-arch dentures are dental implants.
