Porcelain fused to metal (PFM) crowns have a long and tested track record; their ability to provide predictable, lasting results has made it a popular material selection for dentists over the years.
PFM is indicated for teeth that require both high strength and esthetics. PFM crowns are also ideal for patients who need complete coverage to block out a dark Dentin.
TECH TIPS
► Use a metal occlusion if patient is a bruxer.
► If you prefer a porcelain margin, use a shoulder prep.
► If the PFM is part of a precision attachment case, prep guidelines may be different. Call your lab to confirm.
► Prep guidelines indicated here are the minimum for optimal results.
