PFM Multi-Unit Bridge

 

PFM Multi-Unit Bridge (Porcelain Fused to Metal Multi-Unit Bridge) is a fixed dental prosthetic restoration fabricated in dental laboratories for cases with multiple consecutive missing teeth. It consists of a precision cast metal substructure (coping/frame), layered with sintered dental porcelain on the visible surface. The bridge is cemented onto prepared abutment teeth or implant abutments to replace a span of several missing teeth in one integrated unit. Common alloy options include cobalt-chrome and high noble alloys, with shade customized following the VITA shade guide for natural aesthetic outcomes.

 

 

High mechanical strength The rigid metal framework delivers outstanding fracture resistance and load-bearing capacity, ideal for posterior multi-unit spans under heavy masticatory force. It shows reliable performance even for patients with moderate bruxism.

Balanced aesthetics & durability Veneered porcelain mimics natural tooth translucency and shade, while the underlying metal provides structural support. Compared with all-ceramic multi-unit bridges, PFM multi-unit bridge is less prone to chipping or breakage for long-span restorations.

Proven clinical reliability It is a time-tested fixed partial denture solution with decades of clinical data. Dentists widely choose it for full-mouth rehabilitation and long-span tooth replacement.

Cost-effective fixed restoration It offers robust fixed prosthetic function at a more competitive price than full-contour zirconia or implant-supported multi-unit restorations.

Good marginal adaptation Precision casting enables tight margin fit, helping reduce secondary caries and periodontal irritation when properly cemented.

Q1: What is a PFM multi-unit bridge?

A PFM multi-unit bridge is an integrated fixed metal-ceramic restoration used to replace 3 or more adjacent missing teeth. It combines a cast metal substructure with outer porcelain veneer and is retained by natural prepared teeth or implant abutments.

 

Q2: What alloys are available for PFM multi-unit bridges?

The most popular option is cobalt-chrome (base metal alloy). High noble and semi-precious alloys are also available upon request, with lower metal allergy risk.

 

Q3: Where can PFM multi-unit bridges be applied, anterior or posterior?

It works for both anterior and posterior spans. For posterior areas with heavy chewing load, PFM multi-unit bridge is frequently preferred for its superior strength.

 

Q4: What are the limitations of PFM multi-unit bridges?

A thin dark metal collar may be visible at the gingival margin in the anterior zone. In rare cases, patients may have mild metal allergy to base alloy. Gingival discoloration could occur over time adjacent to the metal framework.

 

Q5: How long is the service life of a PFM multi-unit bridge?

With proper oral hygiene and regular dental check-ups, it can serve 8–15 years. The porcelain veneer may chip under extreme heavy occlusal force.

 

Q6: Can you make implant borne PFM multi-unit bridges?

Yes. Our lab fabricates implant-supported PFM multi-unit bridges, following the scan body data and abutment specifications from clinics.
