The modern dental field is actively developing, and therefore the latest methods and means of treatment appear. A popular trend in dental prosthetics is the use of metal-free ceramics. Technology has become a prerequisite for the development of aesthetic dentistry. Products made from this material are durable and harmless. Their varieties and uses are described in the article.
Features
There is no metal in metal-free ceramics. Only ceramics are used in the manufacture of prostheses. This allows you to make the design light and reduce the load when chewing food on adjacent teeth. With the help of metal-free ceramics, it will be possible to eliminate the allergy of the mucous membranes of the mouth, which appears when using metal.
Porcelain is considered a fragile material, but thanks to modern processing methods, it will be possible to make products durable due to the use of zirconium or aluminum oxide as the basis for the frame. Therefore, prostheses can be installed both on the front incisors and on the chewing teeth. Due to the transmission of light and the possibility of selecting the shade of ceramics, such prostheses imitate the hard tissues of natural teeth, giving themnatural shine. Therefore, ceramic teeth are difficult to distinguish from real ones, and besides, they do not change color throughout their life.
Ceramics differ from other products by the period of use - over 15 years. The duration of the term is due to the fact that such teeth are resistant to food dyes, liquids and are unable to absorb odors. These are all the features of metal-free ceramics, allowing them to be used in solving various dental problems.
Types of products
Ceramics are used in the creation of the following fixtures due to their strength and reliability:
- crowns or inlays;
- veneers or laminates;
- dentures.
The crowns of metal-free ceramics are presented in the form of frameless porcelain products, which are distinguished by aesthetic properties. They are ideal for restoring central incisors and canines. Sometimes products allow you to save the rest of a living tooth.
Ceramic inlays are used to completely or partially restore a filling, crown or tooth. Ceramics is recognized as a versatile material that is used in the creation of onlays and veneers. Metal-free ceramics on the front teeth allows you to hide imperfections. With a complete loss of a tooth, orthopedic products are used that are connected with hooks and bridges to adjacent teeth or are installed on implants implanted in the maxillofacial bone.
Benefits
Metal-free ceramic with zirconium hasthe following virtues:
- Obtaining an excellent appearance due to the property of light transmission, the ability to adjust the color of the product and the identity of the size of the lost tooth.
- No noticeable gum-crown border.
- Having a perfectly white tooth surface that reduces the risk of caries and plaque.
- Color fastness that cannot change and stain over time.
- Products cannot react with liquids and oxidize.
- We use safe materials that do not lead to allergies.
- Can be mounted on anterior incisors and posterior teeth.
- Strength of products, surpassing metal.
- The lightness of the prosthesis allows you to reduce the load when chewing food on nearby teeth.
- Ceramic products have good thermal insulation properties, so you can drink drinks of different temperatures without feeling discomfort.
- No need to remove the nerve due to the small thickness of the crown.
- There are a variety of onlays, veneers and prostheses of various shapes and thicknesses.
- This is a gentle way to prepare teeth.
- High-tech methods are used, which, thanks to computer methods, make it possible to create a solid foundation for the ceramic framework.
- Ease of use and quick adaptation to the prosthesis due to its lightness.
- Durable with aesthetic properties and excellent marginal fit.
- Availability of the procedure due to the low cost of ceramic implants.
Thanks to suchadvantages metal-free ceramics is used in many modern clinics. When the work is done by a professional, you can not be afraid of negative consequences.
Production Features
When using metal-free ceramics on teeth, it is assumed that the desired product is individually manufactured. It is carried out according to the following technology:
- An impression is being taken, laser scanning and computer modeling of the jaw on the finished impression.
- Creating a ceramic framework using a milling machine.
- Then the frame is baked in a special oven.
- Ceramic is layered on the frame.
- Required polishing and glazing.
This sequence must be followed in every case. Moreover, this does not affect whether metal-free ceramics will be used on the front teeth or on the back. Only in this case a quality product will be made.
Installation rules
Before installing inlays, lumineers, veneers or crowns, the specialist examines the damaged tooth, takes measures to eliminate poor-quality fillings, grinds the tooth to the desired thickness and performs treatment.
If you need to completely restore the tooth, then the procedure for implanting the implant with the preparation of the base is carried out. A feature of the use of false teeth made of ceramics is that this method of prosthetics does notprocessing and loading of neighboring teeth is expected. To do this, the implant is placed in the gum. When using almost the entire dentition, a bar construction or removable dentures can be used.
After that, an impression is taken, and on the basis of a special scale, the color of the product is selected, corresponding to the natural shade of the teeth. The turned tooth during the manufacture of the permanent crown is covered with a plastic analogue. After creating the crown, the dentist removes the temporary prosthesis and installs the desired element with chemical curing cement.
Indications
According to reviews, many people like metal-free ceramics because of their effectiveness and safety. These products can be used for:
- tooth restoration and correction;
- alignment of the dentition;
- allergies to metal tools;
- correction of defects and damage to teeth.
Even in the presence of such problems, you should first consult with your dentist. It is worth considering all the nuances of using ceramics, as well as reading the reviews of those who have already performed such procedures.
Contraindications
Do not install pottery at:
- deep bite;
- bruxism;
- weak immune system;
- bone diseases;
- presence of inflammation in the mouth;
- pregnancy.
In these cases, you should also consult a doctor. There are probably the mostthe appropriate way to solve the problem based on the patient's he alth condition.
Complications
After installing ceramic products, there is a risk of the following problems:
- color does not match real teeth;
- marginal fit of poor quality;
- inaccurate creation of the anatomical shape of the tooth;
- pain due to the wrong size of the product.
Complications appear if the dental technician in the creation of prostheses took into account only the cast, but did not consult with the dentist. Therefore, it is worth contacting trusted companies for such services. Thanks to a competent approach, it will be possible to prevent complications.
Cost
Prices for prosthetics in each clinic are different. The cost of services is affected by manufacturing technology, the complexity of the work and the cost of materials for their implementation. Find out the exact price after the work.
It should be borne in mind that the cost of metal-free ceramics is high. It can be in the range of 6000-21000 rubles. Moreover, this method of prosthetics is considered one of the most advanced compared to the rest. With the help of lightweight and reliable products, you can achieve an aesthetic effect and preserve the integrity of the remaining teeth.
