DMLS PFM (Direct Metal Laser Sintering System) PFM

A budget friendly option for PFM crowns and bridges.

Laser sintering is the newest technology in metal manufacturing. DMLS is a manufacturing process for producing complex 3D components directly from 3D CAD data without using any machining.

Laser sintering is also referred to as “3D printing” because it builds up framework in a series of successively thin layers. A high powered laser beam is focused onto a bed of powdered metal and these areas fuse into a thin solid layer. Another layer of powder is then laid down and the next slice of the framework is produced and fused with the first. When all the layers have been built up, the solid copings and bridge frameworks are taken from the machine, sand blasted, polished, inspected and ultrasonically cleaned.

Advantages of DLMS Crown And Bridge

DMLS crowns and bridges are made of a particle size of 3–14 μm.  This combined with very fine point laser (0.1 mm) results in a density of 99.9 %, resulting in stronger copings. The densely sintered crowns have practically no voids. The process results in highly accurate, well detailed restorations. Marginal fitting is excellent with the restoration possessing consistent quality and strength. DLMS is a clean alternative to casting.

Coping thickness, pontic design and cement thickness can all be standardized with this method.

Laser sintering is a computer-controlled, precise process that ensures consistent work quality. The possibilities of inclusions or defects that are commonly introduced in the manual casting methods are dispensed with. Multiple unit frameworks usually suffers from distortion in the conventional technique, DMLS is more predictable with improved marginal fit.
