F.A.Q

DENTAL CROWNS AND PROSTHESES

Production of an individual dental crown, bridges for the replacement of several teeth, partial tooth replacement or full tooth row replacement dentures of the upper of lower jaw is a medical procedure of highly aesthetic value and precision.

The most important factor is the appearance of the tooth or tooth aesthetics, which, apart from high technical knowledge, requires every prosthodontist to possess an artistic talent to ensure that your new smile or part thereof is in harmony with the current situation, or, in the event of more extensive prosthetic work, - in harmony with your facial contours and personality.


Jaw muscles are very strong, since they are intended for chewing food. As research conducted in 1994 demonstrates, the average strength of bite of a male jaw fluctuates from 43 kilograms per 1 tooth in the front teeth to 120 kilograms per 1 tooth in the back teeth (https://pubmed.ncbi.nlm.nih.gov/7744385/), which means that the slightest imprecision in the process of dental crown, bridge or denture production may result in damage to the crown as well as harm to the oral cavity health of the patient.


In general, 2 basic types of tooth prosthetics can be identified:

  • Dental crown prosthesis that replaces 1 tooth;
  • Dental bridge, in daily life also called a dental prosthesis, which is used to replace several natural teeth in cases where the production of a dental crown prosthesis of each individual tooth is impossible;


Meanwhile, dental bridges (prostheses) can be classified as follows:

  • Removable dental bridges (prostheses);
  • Fixed dental bridges (prostheses).

Removable dental prosthesis that replaces a large number of teeth and can be removed independently:

  • Fixed dental prosthesis that replaces a large number of teeth and cannot be removed independently.


Dental prosthetics is an individualised and complex process; however, the following basic phases can be identified:

  • During one or two initial consultations, your wishes are discussed with you, an X-Ray examination and photographs are taken, the therapy plan is discussed and costs are calculated;
  • During the next visit, the polishing of the tooth surface, if the construction of the prosthesis is based on the natural tooth, and three-dimensional scanning or obtaining of a spatial impression by using impression material specially designed for these purposes is performed, as well as the determination of the occlusion is performed, if required. The next visit is scheduled to fit and commission the prosthesis, if it complies with your needs and the outcomes planned by your physician. If the prosthesis is based on dental implants, at least 2 intermediate visits will be required to perform the implantation procedure;
  • Then your prosthodontics specialist performs the analysis of the obtained data and forwards them together with additional indications to the dental technical laboratory for three dimensional modelling and production of the crown, which is then followed by communication of your prosthodontics specialist with the dental technical laboratory to produce the prosthesis;
  • When the prosthesis is ready, the fitting of the produced prosthesis will be performed at a prescheduled visit and if the prosthesis complies with your idea and that of your physician, the prosthesis will be fixed and the procedure shall be completed.


Temporary dental crown
In most cases, temporary dental crowns are made of plastic or a composite material to temporarily replace the missing natural teeth, while the dental prosthetic procedures are being performed.

Dental crown prosthesis
The dental crown is produced for 1 tooth; it can be fixed on the existing natural tooth or an inserted tooth implant, which performs the function of the dental crown.

Implant is a recommended option for the support of a dental crown in the event of tooth loss, since, being constantly loaded it will considerably reduce the risk of jaw regression; furthermore, it is functionally and aesthetically more suitable.

Most commonly, dental crown prosthesis is made of the following materials:

  • Porcelain. This material ensures the best aesthetic outcome. Porcelain crown is practically indiscernible from a natural tooth, because, like a natural tooth, it is translucent. The drawback of porcelain crowns is lower durability of the crown;
  • Zirconium oxide. To resolve the problem of low durability of porcelain crowns, computerised milling of durable aluminium oxide or zirconium oxide crown frames is performed, which are then covered with a porcelain coating. Zirconium dental crowns ensure as high an aesthetic result as porcelain crowns, while providing high durability, because the zirconium oxide frame is equivalent to metal in terms of durability, while its aesthetic result is much better thanks to the translucency of zirconium ceramic. Currently this is the most popular material in prosthodontics;
  • Metal (metal ceramic). The core of the crown consists of a thin layer of metal, which is covered with porcelain. Currently they are primarily used for the prosthetics of the lateral and posterior teeth;
  • Plastic or composite material. These crowns are characterised by the early appearance of cracks and change in colour. They are mainly used as temporary crowns;
  • Metal composite or metal acrylate. These crowns are similar to plastic or composite material crowns, except for a thin layer of metal inside the crown to ensure its durability, which is covered with composite material, which is a light material that has the colour of a tooth;
  • Cast metal. These crowns are durable, but their main drawback is their metallic glow, which reduces aesthetic properties, which is why they are commonly used for the restoration of lateral teeth.

Dental bridge or prosthesis
This is a type of dental prosthesis that is used in the following cases:

  • When one or several adjacent natural teeth are missing and they cannot be replaced with individual tooth crowns that are supported by implants;
  • When none of your natural teeth remain in your mandible or maxilla.

The bridge, as well as the crowns can be made from zirconium oxide and metal, which is covered with a layer of porcelain, metal composite or plastic.

Fixed dental bridges (prostheses)

These dental prostheses are either based on the existing teeth or implants, which means that the respective dental prosthesis, after the insertion thereof, is not removable and does not move, which provides psychological and functional comfort, because fixed prostheses best resemble natural teeth in terms of functionality and aesthetics.

Removable dental bridges (prostheses)

The use of removable prostheses can only be recommended in the event, where, due to some reason, the production of fixed dental prostheses is impossible. This means that dental prostheses are not firmly fixed in the mouth and can be constantly removed and replaced again.

The principal drawbacks of this type of prostheses are:

  • Your psychology, due to the sensation of a foreign body in your mouth;
  • Instability of the prosthesis;
  • Loss of jaw bone mass is possible, which is a natural process due to the fact that the removable dental prosthesis does not load the bone sufficiently;
  • When you smile, clamps that are used to fix the removable prosthesis to your natural teeth, are visible.

Removable prostheses are made of special plastic or a combination of metal and plastic. This limited selection of materials is based on the inability of other materials to ensure sufficient mechanical durability.

Removable dental prosthesis on implants

If the removable prosthesis is the only way to replace missing natural teeth, implants are used for fastening them to reduce the drawbacks of removable prostheses, which ensures comfort that is similar to the comfort provided by non-removable prostheses.

These prostheses are mainly used in the cases with a high number of missing natural teeth, or, where all natural teeth in one or both jaws have been lost. Read more on this issue in the FAQ section “Total denture, ALL on 2 and all on 4”.


PORCELAIN PLATES (DENTAL VENEERS)

This is a highly aesthetic restoration that preserves dental tissue. Porcelain plate is a thin layer of ceramic that is used to cover the surface of the tooth in order to improve the colour, shape, size, position of the tooth, etc.

  • Porcelain plates (dental veneers) are produced, if:
  • The tooth has been filled from the visible side;
  • The colour of the tooth has been changed;
  • Pigment defects are visible on the tooth;
  • Natural shape of the tooth has been lost;
  • Larger gaps between the front teeth and other teeth;
  • Uneven tooth rows, etc.

When dental veneers are produced, approximately 0.5 mm of dental tissue is milled off the external (frontal) surface of the tooth. The physician takes an impression of the milled teeth to enable the laboratory to produce porcelain plates of different types. Temporary veneers are produced for use between fitting sessions. The physician fixes the finished veneers to the teeth using special durable cements. Porcelain plates are usually made for the front teeth. The translucency of porcelain plates successfully imitates natural tooth enamel and it can be adjusted to the required/natural colour of the teeth. The porcelain plates do not stain; nicotine, tea or other external factors do not produce stains on them.

TOTAL DENTURE, ALL ON 4 OR ALL ON 2

Total removable prosthesis is used in the cases, where all natural teeth have been lost in your upper jaw, lower jaw, or both jaws.

This type of prosthesis is produced from a metal frame that the gum imitating material - methyl acrylate is fixed to, which is used to fix dental prostheses that are made from special plastic.

Unfortunately, the production of total dentures made of ceramic coated zirconium oxide or metal is currently impossible due to the mechanical properties of the materials.

Traditionally, this prosthesis is fixed to the jawbone and gums. The drawback of this system is the natural loss of jaw bone mass over time, as well as the mobility of the prosthesis.

Therefore, a more modern and sustainable solution is to fix this prosthesis on implants by using a special fixation system.

This prosthetic solution ensures:

  • The feeling of comfort, because the removable prosthesis is stable and functions almost like the fixed prosthesis, ensuring the feeling of natural teeth in your mouth;
  • Better aesthetic appearance;
  • Eliminates the mobility of the prosthesis due to the natural loss of jaw bone mass.

In standard cases, the prosthesis is fixed on 4 implants; however, if due to physiological or financial considerations it is impossible to ensure this type of fixation, the total denture may be fixed on 2 implants. Two implants will not ensure the sensation of natural teeth and stability; however, it will be a much better solution than the production of prosthesis without implant fixation.


The international name of this type of total denture fixation is “All-on-4” and “All-on-2”.

COMPREHENSIVE DENTAL PROSTHETICS AND RESTORATION OF YOUR SMILE

Like in other sectors of medicine, one person cannot specialise in all areas of dentistry. Therefore, upon selecting the dental clinic where you plan to restore your smile, find out whether this clinic contains all the specialists that are required for reaching a therapeutic and aesthetically impeccable result.

In restoring your smile, in addition to the assistance of a prosthetic specialist, you may require:

  • The assistance of an endodontist for the treatment of dental root canal;
  • The assistance of a periodontology specialist for the therapy of gums;
  • The assistance of an orthodontist for the correction of the position of teeth;
  • The assistance of a surgery specialist in order to insert an implant, plastic surgery of the jaw bone and gums;
  • The assistance of a hygienist for the removal of plaque and soft deposits.

Our clinic provides the availability of these specialists in one place.

However, the creation of your smile does not end when your teeth are restored and their position is corrected; therefore, our clinic offers services of a dermatology specialist, who can perform the correction of a gingival smile and reduce bruxism by means of botulinum toxin injections, reducing the need for the use of night mouth-guards. Furthermore, she can also offer medical and aesthetic treatment of the skin of your face (click here to learn more).

Each process of prosthetics consists of the following phases.

Initial prosthetic consultation, during which our prosthetic specialist will:

  • Discuss your desires with you;
  • Perform an initial diagnostic examination;
  • Offer a detailed potential solution to attain your wishes;
  • Prepare your preliminary therapy plan or final therapy plan.

Repeated consultations, in the event of complex prosthetic procedures where the prepared therapy plan is discussed and, if required, the approximate visual solution of the therapy is demonstrated. If you agree to commence the therapy, the therapy plan and the list of specialists of our clinic that you need to visit will be issued to you.

WHY IS IT IMPORTANT TO REPLACE MISSING TEETH WITH IMPLANTS?

In the event of missing teeth, the teeth that surround the empty space start to transform to cover the space, as well as the teeth of the opposite jaw start to grow longer.

These changes may lead to different deformations of your occlusion, which, in turn, can cause problems of a physiological, as well as aesthetic character.
