Full Ceramic Crown

Full ceramic coatings, also known as full porcelain,empress, and emax, are made entirely of porcelain and lack any infrastructuremade of metal or zirconium. They are formed from a single type of material. Bystacking glass ceramics on the crystal core structure, which is strengthened bycompression with high pressure, desired color transitions and aesthetics areachieved. With light refractions and transparency values that are very similarto the tooth, a look that is nearly identical to actual teeth is achieved.

Advantages and disadvantages?

-Since there is no underlying material underneath, it offersexceptional aesthetic qualities. Color selection and light transmittance(transparent) level can be done in great detail. If the tooth that needscoating is dark in color, the color can be concealed by lowering thetransparency level, while the transparency level can be raised if the tooth'scolor should be reflected.

-Thanks to stronger glass crystals, it is shiny and smooth.

-It has no residue due to the enhanced surfacecharacteristics.

-Over time, color does not alter.

-It is in harmony with the tissues of the mouth. On the stateof the gingiva, it has no detrimental effects.

-The degree of tooth abrasion Laminate Although it is lessthan zirconium veneers, it is more than veneer (leaf porcelain).

-It is made in accordance with the patient's expectations aswell as the smile design that is appropriate for the patient's facialstructure.

-It is not advised to be utilized as a bridge for teeth inthe back.

-If it is used on patients who are clenching and grindingtheir teeth, it is fragile and hazardous.

What Circumstances Can It Be Used In?

-Full ceramic coatings with exceptional aestheticcharacteristics can be created in order to achieve the most appropriate colorand shape harmony in anterior tooth restorations where aesthetic concerns andexpectations are strong.

-Correction of a small amount of dental crowding andpositioning issues, such as the closure of a gap (diastema) between the teeth.

-When tooth lengths or curves need to be altered due to old,discolored, or malformed teeth, full ceramic coatings can improve grinaesthetics.

-In cases of developing morphology and discolouration, fullceramic coatings may be used.

-Teeth that cannot be veneered can have full ceramic veneersplaced on them to give them a fresh, attractive appearance since leaf porcelain(Laminate) does not have enough natural surface area.

-To address single tooth defects in the anterior region, itcan be employed in the fabrication of bridges.

What Circumstances Does It Not Apply To?

-Full ceramic crowns cannot be used for bridge building ifthe missing tooth is in the posterior position. Zirconium or metal-based crownswith greater durability ought to be used in these circumstances.

-People with parafunctional habits like clenching (bruxism)or biting a pencil should get metal- or zirconium-based crowns since they aremore force-resistance

-Post- or pin-supported restorations because it could showthe color of the metal.

-In general, zirconium crowns are preferred for implantcrowns because they are more resistant to chewing pressures. 

Stages of treatment

First, the patient's aesthetic aspirations, parafunctionalhabits, jaw relationships, and dental health are assessed. If necessary, wax-upand mock-up studies can be used to illustrate the patient how their teeth wouldlook after treatment. To enable the appropriate alterations to be made in thedesign of the upcoming restoration, the patient's opinion regarding the shape,color, and size characteristics of the teeth is obtained in the interim. Afterthat, the temporary teeth that the patient will wear up until the completion ofthe procedure are produced and the teeth that will be covered are engravedwhile the patient is under local anaesthetic. Using unique resin adhesives, thewhole ceramic covering is bonded to the tooth following the impression and proofingphases.

Treatment Period?

It can be finished in 4 to 10 days (including the rehearsalstages) once the teeth and gums are entirely healthy.
