Overview: This guide provides material specifications, preparation requirements, and billing codes for Dandy’s full metal (alloy) restorations. Use this information to determine the best material for posterior molar cases.
Full Metal Restoration Characteristics
Full metal restorations use biocompatible alloys that offer high strength for posterior molar applications. While these restorations are not highly aesthetic, full metal crowns are recognized for long-term durability.
| Feature | Specification |
|---|---|
| Compressive Strength | 3,000 MPa |
| Tensile Strength | 1,100 MPa |
| Construction Methods | Cast, milled, or 3D-printed selective laser melting (SLM) |
| Material Shades | Gold or Monochromatic |
| Indicated Use | Single unit molars |
| Primary Features | Biocompatibility and high strength |
Full Metal Preparation Guidelines
Follow these reduction and margin guidelines to ensure a proper fit for full metal units. Proper preparation prevents material failure and ensures adequate clearance for the alloy.
Margin Type: Shoulder or Chamfer
Occlusal Clearance: 2.0 mm
Axial Wall Reduction: 1.5 mm
Margin Thickness: 1.0 mm
Material Thickness: 0.5 mm
Full Metal Material Composition Options
Dandy offers four distinct alloy options based on noble metal content. A higher gold percentage results in a more traditional gold appearance for the crown.
High-Noble Rich Yellow (Precious): Composition of 58% Gold (Au), 14 karat.
Noble Yellow (Semi-Precious): Composition of 40% Gold (Au), 10 karat.
Noble White (Semi-Precious): Composition of 24.97% Palladium (Pd) and 70% Silver (Ag).
Non-Precious: Base metal alloy with no noble metal content.
Insurance and ADA Codes
Use the following American Dental Association (ADA) codes for billing and insurance claims related to full metal restorations.
D2790: Crown: full-cast high-noble metal; Pontic: full-cast high-noble metal.
D2791: Crown: full-cast, predominantly base metal.
D2792: Crown: full-cast noble metal.
