Fixed prosthetics

There are many ways to replace lost teeth and the technology and research have allowed us to offer our patients the best!

Fixed prosthetics combines the most recent knowledge from the fields of aesthetic, function and comfort giving the patients the most important thing: safety. As the name itself says fixed restorations replace lost teeth while being permanently cemented (fixed) on the teeth or on implants that support them. Mobile prosthetics comes with a number of problems starting with "My denture will fall out when I sneeze or laugh” leading to the fear that your spouse might see you without your teeth. Although fixed prosthetic substitutes aren't always possible, nowadays the number of cases in which it is recommended is higher than ever. However, tooth replacement isn't the only reason to make a fixed prosthetic substitute. In this day and age when people are, from very different reasons (both personal and professional), very much aware of the importance of a beautiful smile, different reasons can induce them to get a crown, a bridge or veneers and some of the reasons are:

big fillings/ cracked tooth

teeth where a large part of dental tissue had to be removed during the treatment

teeth which are inclined, uneven in colour, tarnished or unevenly shaped

There are several kinds of substitutes that we can make in order for you to get teeth with which you will be completely pleased: veneers, crowns (metal-ceramic, zirconium-ceramic or all ceramic) and the bridges which can be both on natural teeth and implants. For each case we will first make an analysis of the situation in the mouth, as well as x.-ray analysis in order to suggest you the right type of prosthetic rehabilitation which will solve your problems. Well, what kind of prosthetics do you need?

When a large part of the tooth is destroyed by trauma, caries, treatment of the root canal or a combination of the above, and in the case of back teeth or implants, dental crowns and bridges are the solution.

Today in dentistry we have four different ways to make crowns or bridges

  1. Metal-ceramic crown
    The base structure is cast from metal alloy which gives the crown its solidity and resilience to masticatory forces, and the whole crown is covered by ceramics. That way despite the presence of metal we can achieve great aesthetic results.

  2. Gold-ceramic crown
    The main advantages are better aesthetics, bio-compatibility and greater precision in making this kind of substitutes. Many bridges made in gold perform their function well even after 20 years. Today, the gold base is completely covered in ceramics in the making of the construction. That means that the famous "golden tooth” belongs to the past while great properties of gold are combined with premium aesthetic of modern ceramics.

  3. CERCON SMART CERAMICS – high tech all ceramic material
    There are not many materials, such as natural diamond, which combine the outstanding beauty and the firmness. In dental prosthetics ceramic materials combined with metals have been used for years now. Nowadays a high-tech ceramics made of zirconium-oxide is available to us, it has already proved its extraordinary firmness in many extreme conditions, i.e. in heat protection plates on spaceships, disc brakes of sport cars, articulating surfaces of artificial hip joints... The treated zirconium-oxide is white in colour which provides a great advantage from aesthetic viewpoint. The treated material is further moulded and covered in Cercon Cream S ceramics in order to be adapted both in colour and shape to the surrounding teeth and to the natural shape of your mouth. Working with Cercon smart ceramics provides a natural appearance of the tooth as well as extraordinary firmness and bio-compatibility.

  4. Veneers (laminates) are absolutely the youngest members in the family of fixed prosthetics and their primary use is in the correction of aesthetic irregularities in colour and shape, they are used in correcting the position of front teeth less often. They are made of pure ceramics, which is 0,8-1 mm wide, and are cemented with cements which have to correspond in colour to the base, that is to your natural teeth. Only the front of the tooth is sanded, so the removing of the tooth substance is minimal.

One of the most common questions asked by patients are which type of prosthesis is the best and how much does it cost. Firstly patients think that if they pay more, for example for the making of a Cercon ceramic prosthesis, they automatically get a higher quality and a better looking work. Well, that is only partly true. Each of the materials listed above has its advantages and disadvantages, as it is with everything else in life. It is up to your dentist to recommend the type of work which is optimal for you. This is not just a phrase, it is the truth . For example, if front teeth are very damaged with fillings, if their colour has changed or they are devitalized and then restored using posts, it is better to make Cercon crowns rather than veneers. And if a single crown is being placed on an implant in the distal region there is no need for a zirconium upgrade and the crown, etc. Every work is really individual.

After we have decided the type of prosthetics we take into consideration the tooth colour, your wishes, what we can achieve and how. What is the natural shape of your tooth? How did your teeth look before and where you happy with them? What is your awareness on maintaining oral hygiene? Only after we have answered all these questions we can move on to the preparation of the tooth for sanding, sanitation of caries lesions, change old fillings and place composite posts in root canals, then we finally move to the preparation of the tooth itself, which means that we remove as much dental substance as needed to create the space for the prosthetic substitute and to secure its smooth insertion. The modern dental medicine is more inclined towards stair-step chamfer preparation which gives very precise edges and preserves maximally periodontal tissues (the gums and tissues which connect the tooth and the bone). In order to get a precise and quality work it is necessary to take a good impression of the sanded teeth and surrounding structures. The use of retraction thread which retracts the gums away from the edges of the preparation is mandatory, and the impression materials fall in the category of the most modern addition silicones and polyethers.

What happens next? Today it is unimaginable to send you back in the public with bare sanded teeth! The teeth are covered and protected with temporary acrylic crowns which allow you to talk, chew and laugh normally during the short period until the definite completion of the prosthetic work. Finally, the prosthetic work will be permanently cemented (fixed) in your mouth, you will be able to express your satisfaction with it, and maybe it will even give you a new start...

However you should know that...

...fixed prosthetic substitutes aren't eternal, they too have an expiration date, just as the teeth that support the prosthesis. Don't forget that a 20 year-old bridge was placed on teeth that were 20 years younger than they are today.

...fixed prosthetic substitutes demand regular controls and perfect oral hygiene.

...if you suffer from periodontitis you have to take even greater care of your hygiene and controls have to be more often.

...the teeth that are underneath the bridges and crowns are not immune to caries, granuloma or cysts, underneath old bridges you might find all of the above! well made prosthesis can successfully solve your problems with temporomandibular joints and prevent the undesired tooth movement which occurs after the extraction of some teeth!
