PFM crowns (porcelain fused to metal)
MARS USA Dental Lab produces porcelain-fused-to-metal crowns on your choice of alloy — non-precious, high noble, white high noble, yellow gold, or BiO 24-karat gold. PFMs remain a proven, versatile restoration with decades of clinical history. Fast turnaround times on every case.
PFM crowns still earn their place in modern dentistry: proven longevity, forgiving cementation, and an alloy for every clinical (and financial) situation. We also handle the finishing touches PFM cases often need — porcelain labial margins, diagnostic wax-ups and temporary crowns.

Common questions
Which PFM alloy should I pick?
Non-precious for economy; high noble and yellow gold for the classic balance; BiO 24-karat gold for maximum biocompatibility. Note your preference on the Rx or leave it to us with the clinical picture.
What prep does a porcelain labial margin need?
A 90° shoulder — note it on the Rx and we'll finish the facial margin in porcelain for a metal-free look at the gumline.
How long does a PFM crown take?
Fast — the coping is cast and veneered in-house, and we confirm the schedule with you when the case ships.
