All resin crowns
All resin crowns are comparatively less expensive but they undergo wear and tear with time and are vulnerable to fractures.
They are constructed from composite material which is similar to the one used for normal color fillings in the mouth. They are the most natural looking crowns as compared to others.
These are best suitable for restoring front teeth. They also do not wear down the tooth opposing them.
Long back in 1839, the first resin that was used for tooth restoration was vulcanized rubber. After that, technology has progressed and many other types of resins have been discovered which can easily be used for dental applications.
Presently in dentistry, acrylic polymer resins are most commonly used in crowns and dentures. Another common variety that is used is Polymethyl Methacrylate. This particular variety of resin is prepared by blending chemical units known as monomers along with activating chemicals. This enables the monomers to link together and react in order to form long chain polymers. With the reaction in progress, these resins may harden at room temperature. Other types may need ultraviolet light or heat to catalyze the required change.
These crowns are the ideal option for a perfect smile. It is a silicon dioxide mixture filled with tooth colored plastic matter, which is very helpful in restoring the health and look of a tooth.
Since these crowns are not made of metals they can easily be mixed in to a number of shades to match the shade of an individual’s natural teeth.
It also protects the remaining part of the tooth from breakage and temperature changes.
The resin crowns are aesthetically very appealing as they represent the natural look and color of a tooth. In addition, they are metal free. A major disadvantage is that a large part of the tooth structure is removed for placing this crown. Gingival inflammation is more common with this type of crown.
Procedure for fitting a resin crown
It generally is a matter of two visits to the dentist for placing a resin crown. This is so because it takes time as the crown which suits your tooth perfectly has to be hand crafted or custom made in the laboratory which requires skill and expertise.
Initially the tooth under treatment is numbed with local and topical anesthetic. After that, any kind of decay on the tooth is removed. Next, the tooth is reshaped with the help of a hand piece. Then a precise impression of the tooth is taken and a temporary crown is fitted on the tooth.
In the meantime, the permanent crown is manufactured in the laboratory. When the final resin crown is ready, again, the tooth is numbed and the new crown is fitted on it.
Personal care has to be taken when the temporary crown is placed on the tooth. The success of the treatment and the health of the gums all depend on this care.
