A dental prosthesis is a complex biochemical
construction that must replace a lost tooth and copy to the maximum
extent the possible the parameters of a living tooth. The main task
facing the doctors at our centre is to select a replacement design
that not only replaces the missing teeth but also keeps the remaining
teeth for as long as possible.
The
quality of a prosthesis is conditioned by the qualification of the
doctor, the dental technician and equipment of the dental centre. The
prostheses available at the DENTALCENTER are at a high level of
quality and available across the entire range of prostheses, and the
methods and materials used are constantly being improved.
After
the removal of a tooth or several teeth, many patients postpone the
replacement of missing teeth indefinitely, without considering the
consequences. The more time passes from their removal, the more
complicated it becomes to resolve the problem.
In
case of significant deformities of the teeth, the preparation of
prostheses may include orthodontic treatment with preliminary
surgical steps.
Micro-prosthesis
A
micro-prosthesis is a modern and promising method of restoring teeth.
The essence of the method is to recreate the missing part of the
tooth from a ceramic material and to restore the colours, shape,
transparency, gloss and resistance to abrasion.
Microprostheses
include:
Ceramic
fillings
In
the past, aesthetics and functionality competed with one another, and
one of them had to be sacrificed in the process of restoring teeth.
Today,
it is possible to achieve both aims if the tooth restoration is done
with the help of ceramic fillings.
It
is not necessary to grind healthy dental tissues, as is sometimes the
case with a dental prosthesis, such as a crown. The doctor will only
remove the old filling and the tissues attacked by the caries and
will then make a cast or scan the tooth.
The
doctor will insert a temporary filling to wear while the production
of the permanent ceramic filling is taking place. So that the filling
is a natural continuation of the tooth, the colour and degree of
lucidity must be set during its production.
Metal
ceramics are used in the case of a
long-term temporary prosthesis when implants are used. They are less
often used with permanent prostheses, when the degree of damage to
the tooth is so high that ensuring the strength of the structure is
possible only with the help of a solid cast iron frame. The metal and
ceramic materials are chosen according to the specific situation.
Constructions made from alloys of precious metals (gold and platinum,
gold and palladium) or titanium are especially of high quality.
The use of ceramics enables the metal frame to be left out, thanks to the application of solid and lucid the materials made of special ceramics (Empress, Zircon, Emasc).
If
the tooth is very damaged and its root canals have already been
treated, a crown needs to be inserted into such a tooth. In the past,
metal-ceramic crowns were the only aesthetic way to insert a
prosthesis. Their main disadvantage is the reflection of scattered
light, which causes metal-ceramic crowns to look brighter than
natural teeth.
Another
big drawback of metal-ceramics is the formation of a grey shadow on
the edge of the gums.
The
optical properties of non-metallic all-ceramic materials enable
whiteness to be achieved, as in the case of natural teeth, thanks to
the absence of a metal frame, which is particularly desirable in the
prostheses of crowns for the front teeth. Metal-free replacements are
made of bioinert materials and thus do not cause allergic reactions.
