A patient is in the office for a dental examination and has expressed concern over his gold crown on tooth #28. Although the tooth is not causing any problems for the patient, he has said that he does not like the way it looks when he smiles. He had the gold crown placed many years ago and didn’t realize at the time how much it would affect his appearance. What type of fixed prosthesis could the dental assistant recommend to the patient for the replacement of the gold crown on tooth #28?

The patient is a good candidate for a porcelain fused to metal (PFM) crown. Lab technicians fabricate these by adding a thin layer of porcelain over a metal crown. This type of crown is very durable and can withstand forces of mastification. The color or shade of the crown can be customized to the patient's adjacent tooth shade, making it an esthetically pleasing restoration for the patient.

The type of fixed prosthesis that the dentist could recommend to the patient for changing the gold crown of tooth 28 would be the porcelain crown with zirconia, whose advantages are high durability, resistance to bite and corrosion.

Another advantage of the porcelain crown with zirconia is also related to aesthetic factors, as this technique guarantees greater naturalness with the possibility of matching the color of the patient's natural teeth.

Without the use of metal, the porcelain crown with zirconia brings greater biological compatibility and less inflammatory risk, being a good option for restoration and dental rehabilitation.
