Zirconium Dioxide-Based Prosthetics:
the modern standard of aesthetics and reliability
Popularity and relevance of the method
Modern dentistry has made a huge leap forward: if a few decades ago prosthetics were associated with massive metal crowns and discomfort, today it has become a high-tech field. One of the most in-demand solutions is zirconium dioxide-based prosthetics. This material combines aesthetics and strength, making it the number one choice for both front and chewing teeth. According to data from the National Center for Biotechnology Information, zirconia prostheses are used in more than 55% of patients in Europe, and in CIS countries demand for them has doubled over the past 10 years. The reason lies in their high level of biocompatibility, durability, and absence of allergic reactions.
Properties of zirconium dioxide
Zirconium dioxide is a new-generation ceramic material, characterized by strength comparable to metals and aesthetics similar to natural enamel. Its translucency provides a natural appearance, while its low thermal conductivity protects teeth from temperature fluctuations. In studies conducted at Sechenov University (2020), it has been demonstrated that zirconia prostheses last on average 15–20 years without losing functionality, and the risk of allergic reactions is practically nonexistent.
Where zirconia prostheses are used
Based on zirconium dioxide, crowns, dental bridges, and prosthetic structures on implants are produced. Due to their strength, they are installed on molars where the load is greatest. At the same time, their high aesthetics allow them to be used in the front area as well, to create a “Hollywood smile.” Zirconia prostheses are recommended in cases of tooth destruction, enamel defects, hypersensitivity, and the need to restore full dental arches.
CAD/CAM technology
Modern prosthetics is impossible without digital technologies. At Diplomat Med Center, the CAD/CAM method is used, which ensures maximum precision and comfort at every stage.
CAD (Computer-Aided Design) — computer-based design.
First, a three-dimensional model of the dental arch is created with the help of an intraoral scanner. Then, the dentist designs the crown in a specialized program, taking into account the bite and aesthetics.
CAM (Computer-Aided Manufacturing) — computer-based manufacturing.
A milling machine produces the framework from a zirconium block, guaranteeing perfect accuracy of shape. Afterwards, the surface is layered with ceramic to create a natural tooth appearance. Final firing in a specialized furnace gives the prosthesis strength and durability. This sequence eliminates inaccuracies, and the patient receives a perfectly fitted prosthesis fully corresponding to their anatomical features.
Stages of installing a zirconia crown
The procedure is carried out in several steps. First, oral sanitation is performed — treatment of caries, correction of fillings, and elimination of gum inflammation. Then, the tooth is shaped to the thickness of the crown under local anesthesia. A digital impression is taken, on the basis of which the prosthesis is fabricated. During the waiting period, a temporary crown is placed. After fabrication, the zirconia crown is tried in and cemented with dental cement.
Advantages of zirconia prosthetics
The main advantage is the harmonious combination of strength and aesthetics. Unlike metal-ceramic constructions, zirconia does not cause gum darkening and does not provoke allergic reactions. Its hypoallergenic properties are confirmed by the European Academy of Esthetic Dentistry.
Zirconia crowns retain the natural color and shine of enamel, require minimal tooth reduction, and last up to 20 years, which significantly surpasses traditional prosthetic methods. Another advantage is their low thermal conductivity: patients do not feel discomfort when consuming hot or cold food. The light weight of the material reduces the load on the jaw and ensures fast adaptation to the prosthesis.
Who zirconia-based prosthetics are recommended for
Zirconia crowns are suitable for patients of all ages. They are recommended in cases of molar destruction, enamel defects, hypersensitivity, and allergy to metals. Patients who previously wore metal-ceramic prostheses and experienced discomfort note an improvement in both aesthetics and comfort when switching to zirconia. According to international NCBI studies, the satisfaction rate with zirconia crowns exceeds 95%.
Zirconia vs other materials
Compared to metal-ceramic prostheses, zirconia outperforms in aesthetics and hypoallergenicity, while in terms of strength it is not inferior to metallic structures. All-ceramic prostheses without a framework are more fragile and are used mainly in the front zone. Thus, zirconia has become the “gold standard” of prosthetics in the 21st century, combining the strengths of all previous technologies.
Why choose Diplomat Med Center?
At Diplomat Med Center, we use only certified European-level materials and CAD/CAM technologies.
Our prosthodontists select the optimal solution for each patient, whether it is zirconia or ceramic crowns, dental bridges, veneers, or dental implants according to modern All-on-4 and All-on-6 protocols.
Before treatment, a comprehensive diagnostic examination is performed: panoramic X-ray, dental radiographs, which allow for the most accurate assessment of the condition of the teeth and selection of the optimal prosthetic plan. An obligatory step is oral sanitation — caries treatment, gingival therapy, and professional dental cleaning, which ensures the longevity of the future prosthesis.
Diplomat Med Center combines the experience of doctors, innovative technologies, and an individual approach. We help restore not only dental functionality, but also self-confidence, providing a healthy and beautiful smile for many years.
