GETTING A UNIFORM SMILE IN SIZE AND COLOUR IS OUR SPECIALITY
Metal-free crowns and bridges are ideal solutions when the teeth suffer significant damage or fracture and cannot be solved with a veneer.
Unlike veneers, crowns only cover a part of the tooth, they can be placed over the entire piece, correcting aesthetic effects.
Metal-free porcelains reflect light in a similar way to natural teeth, so the appearance is totally the same, and the difference between them is not noticeable.
In this way, the grayish edges, close to the gum, so characteristic of crowns that have metal, are eliminated.
Years ago, metal crowns and bridges were used, but they caused side effects such as allergic reactions.
In our dental clinic in Tarragona we are committed to porcelain crowns and bridges without metal components.
At Clínica Curull we try to ensure that all of our prostheses do not have metal, whether we have to change old prosthesesor make new prostheses for very deteriorated teeth. In any case, rather than placing a crown, we prefer to place an inlay, be it ceramic or composite, because it allows us to preserve healthier tooth structure. And rather than placing a bridge to replace missing teeth, we prefer to place an implant, which does not need to touch any neighbouring teeth.
This only happens in prostheses that have metal under the ceramic. They are usually prostheses of an exaggerated thickness that, with the passage of time, cause a retraction of the gum and the unsightly metallic profile is exposed. In addition, the fact that it is made of metal means that the ceramic does not reflect light and its appearance is unnatural, sometimes similar to a piano key.
Currently, we have materials such as zirconia and last generation ceramics that have great resistance to masticatory and occlusion forces. They are materials that are unlikely to fracture. This makes the thickness of this type of prosthesis much thinner and thus we do not have to excessively touch the teeth, as happened in the old prostheses that had metal.
