D2750 — Crown — porcelain fused to high noble metal

What D2750 specifies

Material — porcelain fired over a high noble, gold-rich core. The core here is a high noble alloy — at least 60% noble metal with a minimum of 40% gold — with porcelain fired over it. Gold-rich alloys are prized for a practical reason rather than a sentimental one: they are chemically inert in the mouth, so the margins do not corrode, and they are ductile enough to be burnished to a very close fit against the tooth. The alloy alone can account for $150–$300 of the laboratory bill, which is why this is the most expensive crown in the porcelain-fused family. The material is part of the code rather than a choice made afterwards, so D2750 is only the right code if that is what was actually used.

The nearby codes and how they differ

D2751 — Crown — porcelain fused to base metal: It specifies porcelain fired over a base-metal core rather than porcelain fired over a high noble, gold-rich core.

D2752 — Crown — porcelain fused to noble metal: It specifies porcelain fired over a noble-alloy core rather than porcelain fired over a high noble, gold-rich core.

D2753 — Crown — porcelain fused to titanium: It specifies porcelain fired over a titanium core rather than porcelain fired over a high noble, gold-rich core.

D2722 — Crown — resin with noble metal: It specifies resin veneered over a noble alloy rather than porcelain fired over a high noble, gold-rich core.

D2750 sits in a group of 15 codes in total; the remainder are linked at the foot of this page. If an estimate lists D2750 and the treatment that follows matches a neighbouring code instead, the office has to resubmit — which delays the payment rather than increasing it.
