Features of implantation of ceramic-based dental prostheses

The loss of teeth in the smile area requires a quick and aesthetic restoration of the dentition. Classical metal-ceramic crowns often create a dark stripe at the edge of the gum due to the gradual oxidation of the metal base.
Dentistry solves this problem by using metal-free structures made of zirconium dioxide and solid ceramics. These materials have biocompatibility and optical properties similar to natural tooth enamel.
Advantages of metal-free structures
Ceramic crowns and veneers based on zirconium dioxide can withstand high chewing loads without the risk of chipping. This material is stronger than metal in strength, but does not cause galvanic syndrome in the oral cavity. The absence of metal components eliminates allergic reactions in patients with high sensitivity.
The light transmittance of solid ceramics is the same as that of natural dentine. The design allows light to penetrate deep into the crown, recreating the natural depth of color and texture of the tooth.
High aesthetic performance is achieved due to the following factors:
- accurate computer modeling of the frame using CAD-CAM technology;
- the absence of a metal substrate under the light-permeable layer;
- the possibility of individual selection of the shade on the Vita scale;
- the minimum thickness of preparation of hard tooth tissues.
The precision of the edge fit prevents plaque accumulation under the gum. This eliminates the development of marginal gingivitis and guarantees a stable condition of the soft tissues around the implant. The transition to the surgical intervention stage requires detailed planning of bone grafting.
Surgical stage and implant integration
The installation of a titanium screw into the bone tissue serves as the foundation for future ceramic restoration. If there is a lack of volume of the alveolar process, sinus lifting or targeted bone regeneration is performed. The ceramic crown requires a stable base so that the chewing pressure is distributed physiologically correctly.
The period of osseointegration in the lower jaw takes three months, and in the upper jaw it takes about six months. At this time, the patient wears a temporary prosthesis made of composite materials to preserve aesthetics and chewing function.
The process of engraftment of the structure is monitored using diagnostic methods:
- dental computed tomography;
- assessment of the stability of the implant by the Osstell device;
- visual examination of the condition of the mucous membrane;
- control of oral hygiene in the posterior zone.
The stable fixation of the titanium support eliminates the micro-mobility of the structure under load. After the osseointegration is completed, the orthopedic dentist proceeds to form the gingival contour before permanent prosthetics.
Features of the orthopedic stage and crown fixation
Creating a beautiful gingival edge around a ceramic crown requires the use of an individual zirconium dioxide abutment. A standard titanium abutment can shine through a thin gum, giving it a bluish tinge. The zirconium support merges with the color of the tooth, preserving the natural appearance of the soft tissues.
The finished structure is fixed on a special double-cured composite cement. This material provides a strong connection between the ceramic and the abutment, eliminating cementation under load. The patient is advised to avoid pinpoint loads on the crown, such as cracking nuts or solid household objects.
The durability of metal-free prostheses ranges from 10 to 15 years, subject to regular hygiene. The use of an irrigator and professional cleaning in the clinic twice a year preserve the original shine of ceramics and the health of surrounding tissues.
