Dental restorations created by a master's hand

A glimpse into the creation of dental masterpieces

Just like regular medicine, dentistry is a broad field nowadays. To show you what we create in our laboratory and how, here is a small summary.

What we do

We have a clear concept of modern dentistry — the combination of the finest handcraft, digital computer aided design (CAD) and computer aided manufacturing (CAM) technology. We have uncompromising standards in our laboratory and work to the same quality control as in our dental procedures. Producing the perfect restoration for your mouth is as important to us as the preparation and fitting procedure. 

The foundation of all dental works are models — copies of a set of teeth. To begin with an impression of your teeth and gums is taken and cast. In the gallery below you can see models prior to any procedures but after the grinding, which is done as preparation for dental crowns and bridges.

A wax up is the diagnostic visualisation of the planned treatment, and it is done before beginning the procedure. The wax up allows the dentist and the patient to decide on the desired form of dentures. It also shows which measures must be undertaken to reach the desired result, such as additional implants, bone augmentation and gum corrections.

Partial crowns are a therapeutic option if the destroyed area of the tooth is too large for a filling or an onlay, but too small for a dental crown. This way we can save tooth substance when grinding the tooth, as we have to replace only the defective parts of the tooth. Modern partial crowns are made of milled or pressed ceramic.

Fixed implant supported single tooth crowns are usually full ceramic crowns. The soft tissue has contact only with biologically compatible materials such as lithium disilicate or zirconium oxide ceramics. The secure connection between the tooth and the implant is achieved with a titanium base. Single tooth crowns can be screwed into the implant or cemented onto an intermediate structure (abutment). If you are interested in seeing some of our cases please go to our video library.

What materials do we use?

Fixed restorations

Partial crowns, full crowns, implant supported restorations and dental bridges are made from "full ceramic", which means the restorations are completely metal free. This allows a natural aesthetic that meets the highest standards. We choose the type of ceramic on a case by case basis.

Advantages of all-ceramic restorations:

  • The light can pass through them as through a natural tooth. Through the ceramic light is transmitted to the tooth core and the surrounding gums. Even the crown edge is invisible.
  • Ceramic is colour-resistant, so no discoloration occurs in the long term.
  • Ceramic is a material from nature and fits the biological structure of the human body. This is why ceramics are highly compatible with the mouth and are allergen-neutral — in short, they are biocompatible.
  • Since ceramics are highly glazed, plaque does not adhere. This is a great advantage for the health of teeth and gums.
  • Ceramic is resistant to abrasion and acids.
  • Ceramics can be adhesively bonded and force-locked to the residual tooth so that the restoration protects the tooth substance.

 

Removable restorations

Dentures that have both fixed (crowns, bridges, implants) and removable parts are called combined dentures. Connecting elements between the parts may, for example, be so-called telescopes (also called "telescopic crowns", "double crowns" or "conical crowns"). The wearing comfort is very high in the combined dentures — the denture sits securely and firmly, and the aesthetics are very appealing.

With the help of telescopes, removable bridges and partial dentures can be safely fixed in the mouth. The prepared tooth stumps next to the tooth gap are given a full ceramic crown, which consists of two parts. The primary crown (inner, primary telescope) is cemented to the prepared tooth stump and sits tight and fixed. Then the natural-looking, removable secondary crown (external, secondary telescope) is set, onto which the additional dentures (bridges or partial dentures) are attached. The secondary crown holding the removable denture slides over the primary crown and sits securely and firmly in place after insertion. It keeps the removable dentures reliably safe. This connection between fixed and removable dentures is easy to handle, very durable and highly expandable. The telescoping bridges and prostheses are absolutely indistiguishable from a natural dentition — nothing indicates when laughing or talking that you have dentures.

We make the telescopic work with the help of full ceramic and in most cases the framework is made out of metal free PEKK (polyethylene-keton-keton).

Allergies

Allergies and so-called environmental problems are increasing. We encounter many patients who are allegic to metal prosthetic materials, so one of our services is the production of biocompatible fixed and removable restorations. A material is biocompatible if it behaves neutrally in the body.

Biocompatibility in dental work depends on several factors:

  • the composition of the material
  • the manufacturing process
  • the correct processing by dental technician and dentist
  • the oral flora, especially the salivary composition.

Very good biocompatible dentures made of all-ceramic are an aesthetically pleasing and very well-tolerated solution. As we generally do not use metal any more for dental restorations, all-ceramic materials dominate the daily manufacturing process.


Clarifying some dental nomenclature

A veneer is a thin ceramic shell used on front teeth to fix aesthetic and functional problems. The veneer is glued onto the tooth to transform its colour, form and apparent position.

Tooth-supported full ceramic bridges are used when one or more teeth are missing. Small bridges can be pressed out of lithium disilicate ceramic to replace a single tooth and, if multiple teeth are missing, bridges with zirconium oxide ceramics or metal frameworks can be fitted, where the ceramic base frame is blended with the other materials. Alternatively a complete denture can be milled out of one block of zirconium oxide ceramic. This type of full ceramic bridge is more stable and is suitable for patients who suffer from extreme teeth grinding or clenching (bruxism).

Permanent implant supported single crowns are usually made of full ceramics. This means the soft tissue is only in contact with biologically compatible materials such as lithium disilicate ceramic or zirconium oxide ceramic. The titanium base guarantees that the implant will be securely kept in place. Single crowns may be screwed into the implant. Alternatively they may be cemented onto an intermediate structure (abutment).

Fixed implant supported dental bridges are used to replace several missing teeth. Full ceramic bridges made of lithium disilicate or zirconium oxide are used for front teeth to guarantee beautiful aesthetics. For back teeth we use bridges with an inner metal framework that are resilient to chewing forces to achieve the maximum service life.

A special type of an implant supported bridge is the screw retained full arch bridge. This type of denture allows a fixed tooth replacement with only four implants in each of the upper and the lower jaws, used in cases of complete toothlessness (edentulism). With a special surgical method we can insert this type of denture on the same day as the implants are placed, for immediate functionality. 

In the early 90s fully ceramic adhesive bridges were introduced as a minimally invasive prosthetic therapeutic method. This enables us to replace lost back and front teeth without losing large amounts of tooth substance due to grinding during preparation. They have become an established treatment option for the aesthetic replacement of back teeth in the upper and lower jaw. Adolescents who are missing teeth may especially benefit from this method. Adhesive bridges are a cheaper alternative to implants or conventional dental bridges.


Metal vs all-ceramic: which bridge should it be?


Bridge restorations are a common way to close tooth gaps. Anyone who has opted for this type of restoration is faced with the next question: which material should it be? Metal ceramic bridges or all-ceramic bridges?

High quality bridges should...
Be made of a stable material and be designed to last as long as possible. At the same time they should have an abrasion-resistant surface, be biocompatible and look appealing. Most bridge materials meet these criteria with appropriate processing. Nevertheless, the materials differ in the details.

Pure metal bridges 
Pure solid metal bridges are stable and cheap, but not tooth colored. Because they can catch your eye, conduct heat and cause a metallic taste, they are barely used today. Even bridges made of gold are rarely used. However, full metal bridges are suitable from the fifth tooth in the upper jaw and the fourth tooth in the lower jaw.

The 'gold' standard: pros and cons of metal-ceramic bridges
Metal ceramic bridges consist of a metal framework, which is veneered with ceramic. It has been used in dentistry for over 50 years, so dentists have gained a lot of experience with these materials. Because the metal framework is very stable, this denture can also close larger gaps. Due to the tooth-coloured appearance, metal-ceramic bridges are also aesthetically pleasing. In addition, they are less thermally conductive than full cast bridges.

After five to ten years, however, the gums may discolour because metal ions dissolve. In addition, the aesthetic appearance may suffer because deeper layers may shimmer through or the metal rim may become visible as the gums recede over the years. 

All-ceramic bridges made of lithium disilicate
For a long time there were only metal and metal ceramic bridges, but the search for better aesthetics eventually led to the development of all-ceramic bridges. They are almost indistinguishable from natural teeth. All-ceramic is also considered to be biocompatible.

Lithium disilicate bridges hold as long as metal-based bridges, but can only be used for individual tooth gaps in the area of ​​the small molars and anterior teeth. Like normal teeth, they can break when hard food needs to be crushed.

High performance ceramic zirconia
More and more zirconium bridges are being used, which work like full ceramic bridges without metals. Zirconium oxide is very resilient, therefore zirconium oxide ceramics are also used for several missing teeth in the posterior region. However, this extreme stability also has disadvantages, because the opposite tooth can be worn down if the bridge has not been sufficiently polished after grinding in the bite. The bridges fit seamlessly into the teeth like full ceramic restorations. However, it should be ensured that the zirconia veneering ceramic is applied only on the outside, since the veneering otherwise often splinters.

Since zirconium bridges can be manufactured by computer-controlled systems, they impress with their high accuracy of fit and material purity.

Which bridge is the right one?
Ask yourself the following questions: ss a tooth-colored restoration necessary, for example because the gap is in the visible range? Do you prefer metal-free materials? In these cases, a full ceramic or a zirconia bridge could be the right choice. If the edge of the bridge is not visible, a metal-ceramic bridge can also be considered.
