PFM Crowns
Material Profile
Porcelain-fused-to-metal crowns combine a strong metal coping with a layered ceramic exterior. They remain a reliable option for posterior stress zones and long-span treatment planning where durability is essential.
Design options include shoulder or chamfer margins, metal collar choices, and customized occlusal contact intensity based on the clinician's preference.
Indications
- Posterior crowns with heavy bite force
- Cases requiring stable long-term support
- Patients prioritizing value and function
Clinical Advantages
✓ Proven framework strength and predictable seating.
✓ Flexible design for pontic and occlusion adjustment.
✓ Balanced esthetics and cost for routine fixed cases.
Technical Specifications
Manufacturing Excellence
- Digital waxing or CAD coping design for consistent fit
- Opaque layering optimized for metal masking and shade base
- Multi-bake porcelain technique with natural translucency
- Individual glaze and characterization to match adjacent dentition
- Final quality check: marginal integrity, occlusal contacts, and proximal fit
Extended Indications
Relative Contraindications
- Patients with known metal allergy (alternative: zirconia or Emax)
- High esthetic demand in anterior zones (opaque metal substructure may show grey line)
- Extremely limited interocclusal space (<1.5 mm total)
PFM vs. Alternative Materials
| Criteria | PFM Crowns | Full Zirconia | Emax (Lithium Disilicate) |
|---|---|---|---|
| Fracture Resistance | Very High (metal coping) | Extremely High | High (monolithic) |
| Esthetics | Good (opaque core) | Moderate (can be layered) | Excellent translucency |
| Tooth reduction | ~1.5–2.0 mm | ~1.0–1.5 mm | ~1.2–1.8 mm |
| Cost Efficiency | Most affordable | Mid-range | Higher premium |
PFM Fabrication Workflow
1. Model & Die
Digitized or conventional die spacer & margin marking
2. Wax / CAD Pattern
Metal coping design, precision fit
3. Ceramic Layering
Opaque, dentin, enamel & glaze
4. Finishing & QC
Occlusion, contacts, polish & delivery
Clinical Cases & Outcomes
PFM restorations deliver reliable function and natural integration
Case #2411: Severe occlusal wear & fractured amalgam
Pre-operative condition
PFM crowns #18, #19, #30 – excellent contour & occlusion
6‑month follow‑up: stable margins, no sensitivity
Long‑Term Track Record
PFM crowns have decades of clinical data with survival rates >94% at 10 years in posterior segments.
Flexible Margin Design
Supports supragingival, equigingival, or subgingival preparation based on esthetic priority.
Cost‑Predictable Solution
Ideal for insurance-based cases and large-volume prosthetic planning without compromising strength.
Frequently Asked Questions — PFM Crowns
Everything you need to know about porcelain-fused-to-metal restorations
Are PFM crowns still a good choice compared to full ceramic?
Yes, PFM crowns remain the gold standard for posterior high-load cases. They offer exceptional longevity and are more cost-effective, although full ceramic may be preferred for anterior esthetic zones.
What is the typical turnaround time?
Standard delivery is 5–7 business days from case receipt. Expedited services (3–4 days) can be arranged for urgent clinical needs.
Can I request a specific metal type?
Absolutely. We offer high-noble, noble, and non-precious alloys. Indicate your preference on the prescription form or during case planning.
How is shade matching managed?
We follow VITA classical 3D-Master shade guides. Submit high-quality photos or a custom shade tab, and our ceramists layer porcelain to achieve lifelike esthetics.
What warranty do you offer on PFM crowns?
Deyu Dental Lab provides a 5‑year limited warranty against porcelain fracture or manufacturing defects under normal function. Remakes due to fit or shade are coordinated promptly.
How to send impressions or digital scans?
We accept PVS impressions, 3M™ True Definition, iTero, and CEREC files. Ship via prepaid label or upload digital scans through our lab portal.
