Dental prosthetics

Dental crowns

According to the needed load, aesthetical requirements, and the economic abilities the following types of dental crowns can be produced:

Procedure description

• Once the patient and the dentist have agreed upon the appropriate treatment, the treatment process is started.
• If needed, anaesthesia is applied.
• An imprint is made to produce a temporary crown.
• A tooth gets grinded by the special tools to make application of a temporary crown of appropriate thickness and later the true dental crown possible.
• Once the tooth has been grinded, an imprint and also the occlusion register are developed. A temporary crown with temporary cement is placed.
• During the following visits first the crown base, then also the completed crown is to be fitted. The crown is fitted in occlusion and all the needed corrections are made. If the colour and shape fits, the crown is to be sent back to the laboratory in order to be enamelled.
• At the last visit the crown gets fixed with special cement.

Dental bridges

According to the needed load, aesthetical requirements, and the economic abilities the following types of dental bridges can be produced:

Procedure description

• Once the patient and the dentist have agreed upon the appropriate treatment, the treatment process is started.
• If needed, anaesthesia is applied.
• An imprint is made to produce a temporary bridge.
• The support teeth get grinded by the special tools to make application of a temporary bridge of appropriate thickness and later the true dental bridge possible.
• Once the tooth has been grinded, an imprint and also the occlusion register are developed. A temporary bridge with temporary cement is placed.
• During the following visits first the bridge base, then also the completed bridge is to be fitted. The bridge is fitted in occlusion and all the needed corrections are made. If the colour and shape fits, the bridge is to be sent back to the laboratory in order to be enamelled.
• At the last visit the bridge gets fixed with special cement.

Recommendation!

• In order to make a dental bridge, two support teeth are to be grinded. Make sure whether a dental implant would not result in better treatment of the defected area.
• A dental bridge needs special care, so do not forget to floss it with a special floss threader for flossing under the dental bridges as well as schedule regular visits to the hygienist.

Root inlays

In case a tooth has lost most of its crown tissue it needs a root inlay to be put in. A root inlay is placed in the dental root and a crown of artificial coating is to be cemented upon it.
A root inlay can be made both of metal (if metal ceramic crowns are used) and zirconium (for no-metal crowns). These do not differ functionally but aesthetically – when applying no-metal crowns, a metallic inlay may show through.

Procedure description

• A root inlay is paced in a tooth that has received endodontic treatment, shows no sign of inflammation and the crown part of which has been lost so that the tooth can be restored by application of a root inlay.
• The crown part of the tooth gets prepared for a root inlay as well as the endodontic filling gets partially removed from the root part of the tooth. The dentist shapes a plastic sample of the inlay that is to be moulded or cut of zirconium at the laboratory. A temporary crown is applied to the tooth.
• In the following session the inlay is to be fixed with special cement and a new temporary crown is made.
• The tooth is prepared for further prosthetics.

Dental veneers

Porcelain plates or veneers are used in order to improve the aesthetics of the incisive teeth for instance to treat dental discolouring, to even the dental row or to strengthen the teeth.

The porcelain plates are from 0.2 to 2 mm thick, so just a little gets grinded from the natural tooth and the tooth does not lose its functionality and durability.
If the teeth are carefully maintained and protected (from bruxism for example), the average term of service for veneers is 10 years.

Procedure description

• At the first visit an imprint is taken so that temporary plates may be made. In the laboratory a wax-up with a sample of future porcelain plates is made.
• During the following visit the teeth get grinded and temporary veneers are made of special plastic.
• An imprint for the true porcelain veneers is taken.
• At the first fitting session the base of the plates is adjusted, at the following time the veneers are to be fitted to ensure their colour are shape are correct and they fit the occlusion.
• If everything concords the requirements, the plates are fixed with special cement.

Removable dental restorations

Removable dental restorations are used in case of partial or complete loss of teeth. Removable prosthetics are used when they may not be replaced with irremovable dental restorations as well as a temporary solution before the implants have been placed. Dental prosthetics are financially more accessible than irremovable dental restoration and it is also a simpler prosthetics method as it does not involve any invasive interference in the oral tissue.

Procedure description

• When the patient and the dentist have agreed upon the most appropriate method, the treatment process is started. The first imprint is to be taken. If the patient has lost the lateral teeth, the laboratory uses the first imprint to make a special individual imprint spoon so that the true imprint can be taken with maximum precision.
• During the following visit the height of occlusion is determined by a laboratory-made wax preparation so that the respective denture fit the height of the patient’s occlusion. The colour of the new denture is also determined during this visit. The wax try-in is to be sent to the dental laboratory. In case a metal denture is to be made, the metallic base is adjusted at this time.
• During the following visit the teeth that have been placed in a wax try-in are fitted to the patient. The patient can visually assess the appearance and the size of the denture and its compliance with the occlusion.
• If the previous visits have been successful, the new denture is handed to the patient.

Recommendation!

• Once the removable denture has been handed to the patient it happens that it weighs on the soft tissue of the oral cavity. It is absolutely normal as the oral mucous membrane is not used to such a burden. In such a case you should bay all means contact your dentist and schedule for the denture correction.
• The denture should be kept clean but it should not be excessively rubbed – it must not be rubbed by sharp brushes or abrasive pastes. Using special tablets for marinating the denture clean is the best option.
• The patient should not forget also to take care of the existing teeth and the oral mucous membrane.

Night splint

Nowadays a term of bruxism is becoming more widespread. Bruxism or teeth grinding is contractions of chewing muscles which results in grinding the teeth against each other with quite a force. Teeth grinding often happens at night still it is widespread also during the daytime when one is highly concentrating for instance when working at the computer or during a physical load.

What does it do to our teeth?

The teeth are wearing out; the occlusion key – an eye tooth – gets worn out first and then gradually also the surface of other teeth gets uneven until total deterioration has developed over entire occlusion – the teeth have lost their vertical height, they have shortened.
People mostly do not feel and do not notice this as the process is gradual, so both the joint and the muscles adjust to the new height of the teeth. It often happens that the patients do not believe it when told they have bruxism, but teeth grinding takes place during sleep or while concentrating at some other activity therefore it goes unnoticed.
As the reason of teeth grinding is found in the activity of the central nervous system, there is no medicine available to prevent it. However, we can prevent further wear of the teeth – the people who suffer from bruxism should use a night splint every night. It is an individually shaped rubber splint that is placed on the bottom (more seldom the upper) teeth in order to amortise the mutual contact of the teeth so that they do not touch each other and stop wearing out.

Procedure description

• An imprint of the patient’s teeth is taken and sent to the laboratory for producing a night splint.
• During the following visit the patient is given a night splint and advised to use it every night.
