Crowns and bridges, colloquially known as caps, can be made of different materials. They can be made on milled teeth or as a replacement on an implant.
Crowns and bridges crafted of metal-ceramics have a metal base and layers of ceramics on it. They yield satisfactory aesthetic and functional results, but because of the metal base, they do not leak light as natural teeth do, so the difference between the crown and natural teeth can be noticeable, which is especially important in the aesthetic region of the upper jaw. It is in this region that is recommended to install metal-free crowns based on zircon, which is white and gives the crowns a natural appearance under natural light. Also, when gums withdraw overtime, no dark lines between the gums and the zirconia crown tooth will appear as it can be the case with metal-ceramic crowns. Due to the good mechanical properties of the zirconium, it is possible to craft crowns even on the side teeth and implants. Crowns, whether metal-ceramic or zirconia crowns, can be attached to implants in two ways – by cementing or by a screw, which is decided by the dentist in collaboration with the dental technician. The part to which the crown is cemented, called abutment, is screwed into the implant and can also be made of zirconium or titanium.
We also recommend Bio HPP (High-Performance Polymer) material as a very good solution for restorations on a large number of implants. What makes it special compared to other materials is its elasticity similar to the one of the bone, which is of paramount importance when we speak of the forces implants receive when chewing, then their biocompatibility, stability, the possibility of high-level polishing preventing plaque accumulation and discoloration of the material as well exceptional aesthetic characteristics.
