PFM dental crowns and bridges combine a metal framework with an outer layer of porcelain. Choosing a design starts with the clinical goal, the restoration site, its support type, and the requirements sent to the laboratory. A useful prescription gives the dental team and laboratory the same practical details to work from.

PFM Dental Crowns and Bridges: Choosing for a Clinical Case
Start with the job the restoration needs to do. Is the plan for a single crown or a bridge? Will it be supported by natural teeth or implants? Where will it sit, how much restorative space is available, and what does the patient expect the visible portion to look like? These details shape the design request.
Before sending the case to the laboratory, use a short checklist to catch missing information:
- Identify the teeth or implant sites the restoration will cover or replace.
- Record the available space and relevant bite contacts.
- Describe the patient’s expectations for the visible area.
- State the support type and any design requirements the laboratory should follow.
Record the required contour, metal framework, porcelain coverage, and support type. Send the laboratory the restoration site, support type, available space, bite contacts, and appearance requirements. Those details give the lab a concrete basis for reviewing the prescription and raising questions before fabrication.
Use this table to check the prescription before fabrication.
| Decision factor | What to confirm | Why it matters |
|---|---|---|
| Restoration type | Crown or bridge | Identifies the requested design |
| Support | Tooth- or implant-supported | Provides the case context |
| Available space | Space for the planned restoration | Informs the design discussion |
| Appearance | Patient’s expectations for the visible area | Guides porcelain planning |
Evaluate the Metal Framework and Porcelain Design
A PFM restoration has two main parts: a metal framework that supports it and porcelain that forms the visible outer surface. The prescription should identify the requested framework, the alloy, and where porcelain should cover the metal. If those details matter to the treatment plan, write them down rather than leaving them open to interpretation.
Blue Sky Dental Lab offers high-noble metal alloys and cobalt-chromium frameworks for PFM restorations. Ask the laboratory which alloy meets the case’s material requirements. Name the alloy and framework design on the prescription, and confirm both before fabrication if the treatment plan specifies a material.
Specify fit requirements and visible porcelain coverage in the same prescription. The lab catalog describes CAD/CAM marginal precision and digital internal fit as capabilities, but the laboratory still needs the case information and the intended design. Include details about the preparation or supporting structure, the areas that should receive porcelain, and the patient’s appearance expectations. For PFM dental crowns and bridges, specify framework and porcelain requirements together on the prescription.
Planning PFM Restorations for Implant-Supported Cases
For an implant-supported restoration, identify the type of restoration and the implant details relevant to its design. State whether the request is for a crown or bridge, which implant sites are involved, and how much restorative space is available. Use those details to confirm whether the proposed design fits the case.
Include the records and instructions the laboratory needs to understand how the restoration relates to the implant and the rest of the case. List the implant sites, restorative space, and clinician’s design requirements on the prescription. If there are specific requirements for the support or connection, state them directly so the laboratory can review the request and ask about anything that is unclear.
Dentists reviewing options can consider Co - Cr Pfm Dental Crowns And Bridge as one available PFM restoration. Confirm the intended material and design with the laboratory, and describe the case’s support and restorative requirements on the prescription. Name the person responsible for confirming the prescription when several team members are involved.
Common PFM Case-Planning Mistakes to Avoid
A prescription that omits the restoration type, alloy, or porcelain coverage leaves those choices unresolved. A general request for a PFM restoration may not tell the laboratory whether the case calls for a crown or bridge, which material to use, or where porcelain should cover the framework. Include the information that affects the planned design, along with any requirements the lab should confirm before fabrication.
Restorative space and bite contacts are easy to overlook when the prescription focuses only on the restoration itself. Record the available space and share the bite information relevant to the design. If a requirement is uncertain, raise the question early. Resolve design questions before fabrication.
Record the patient’s visible-area expectations and the relevant tooth or implant support. Then review the proposed design against the case details, material request, and clinical goals. Confirm the material, support, and design against the prescription before fabrication.
PFM Crowns and Bridges: Frequently Asked Questions
Review case-specific questions with the treating clinician and laboratory. The answers below cover common questions, but the details of a particular treatment plan should guide decisions about an individual restoration.
For a treatment-specific answer, consult the case records and clinician’s instructions. Confirm the requested restoration and next steps with the clinical team.
What does PFM mean in a dental restoration?
PFM means porcelain fused to metal. The restoration combines a metal framework with a porcelain covering. The dentist and laboratory should specify the framework, material option, porcelain coverage, and planned appearance for the case. The treating team can explain how those choices fit the clinical request.
Can PFM be used for both crowns and bridges?
Yes. PFM restorations are available as crowns and bridges. The treatment plan and clinician’s assessment determine which type is being requested. The prescription should identify the restoration and explain its intended support and design so the laboratory can review the request.
What should a patient do if they have a concern about a PFM restoration?
Contact the treating dental professional and describe the concern. The clinician can examine the restoration and recommend follow-up based on the patient’s situation. Follow the care instructions provided by the dental team, since they are specific to the restoration and treatment plan.
For PFM dental crowns and bridges, send Blue Sky Dental Lab the case requirements and review material options with your dental team. Before fabrication, make sure the prescription identifies the restoration type, support, material, available space, and appearance requirements. Contact the laboratory with any design questions that remain.
