Laser PFM (DMLS)

DMLS, Titanium, PFM & Metal-Ceramic Restorations

Laser PFM (DMLS)

Laser PFM restorations use Direct Metal Laser Sintering (DMLS) technology to build the metal coping layer by layer from a digital file. This advanced process eliminates the distortion associated with conventional casting, resulting in superior marginal fit and biocompatibility.

The laser―sintered metal framework is then layered with high―quality feldspathic porcelain by skilled ceramists to achieve excellent aesthetic results. Laser PFM is ideal for cases requiring the highest level of fit accuracy and for patients with metal sensitivities to conventional casting alloys.

Key Benefits

✓ Superior marginal fit vs traditional casting
✓ DMLS technology for accuracy
✓ Reduced porosity in metal framework
✓ Excellent biocompatibility
✓ Ideal for complex bridge cases
✓ Digital workflow precision

Questions & Answers

Frequently Asked Questions

What is DMLS technology? +

Direct Metal Laser Sintering (DMLS) is an additive manufacturing process that builds the metal coping layer-by-layer from a fine metal powder using a precision laser guided by a digital (CAD) file. Unlike traditional casting, DMLS eliminates shrinkage and distortion during solidification, resulting in a coping with exceptional dimensional accuracy.

How does Laser PFM compare to a conventionally cast PFM? +

The primary advantage of Laser PFM is superior marginal fit. Conventional casting introduces controlled distortion during the cooling phase. DMLS builds the coping digitally to exact specifications, consistently achieving marginal gaps below 50 microns. This translates to less chairside adjustment, better long-term sealing, and reduced risk of secondary decay.

Does Laser PFM require a digital impression? +

No. We can work from both conventional impressions (from which we scan a working model) and digital STL impression files sent directly. If you are already using an intraoral scanner, sending an STL file directly streamlines the workflow.

Is Laser PFM more expensive than Regular PFM? +

Laser PFM is priced slightly higher than Regular PFM due to the digital workflow and DMLS technology involved. However, the improved fit typically results in reduced chairside adjustment time and delivers a better long-term clinical outcome, making it highly cost-effective in practice.

Is DMLS metal biocompatible? +

Yes. The cobalt-chromium alloys used in DMLS are medical-grade and widely accepted as biocompatible. They contain no beryllium and comply with ISO 22674 standards for dental casting alloys. For patients with known cobalt or chromium sensitivities, please consult with us about alternative alloy options.
