D6093 Dental Code: Crown Repair – Porcelain/Ceramic Substrate
Dental crowns are a crucial restorative solution for damaged or weakened teeth. However, even the most durable crowns—especially those made of porcelain or ceramic—can sustain damage over time. The D6093 dental code specifically refers to the repair of a porcelain or ceramic crown, a common procedure in restorative dentistry.
This comprehensive guide explores everything you need to know about the D6093 procedure, including its applications, techniques, materials, costs, and preventive measures. Whether you’re a dental professional, a patient, or a curious reader, this article provides in-depth insights into crown repairs.
2. Understanding the D6093 Dental Code
Definition and Scope
The D6093 code is defined by the American Dental Association (ADA) as:
“Repair of prosthetic crown – porcelain/ceramic substrate.”
This means it applies only to repairs involving porcelain or ceramic-based crowns, not metal or composite crowns.
When Is D6093 Used?
-
Chipped or fractured porcelain
-
Worn-down ceramic surfaces
-
Debonding or minor cracks
If the damage is extensive, a full crown replacement (D2740) may be necessary instead.
