DMLS PFM (Direct Metal Laser Sintering System) PFM

 

DIRECT METAL LASER SINTERING (DMLS) is latest technology for manufacturing dental crown and bridges.  This system uses Computer Aided Design (CAD) data to fabricate the desired frame by selectively sintering the alloy powder layer by layer. This machine uses special based alloy, which is highly bio-compatible. It offers a high tensile strength of 1350mpa and has an excellent bonding strength.

 

DMLS PFM is a PFM material with 10 years warranty.

Dental technology is undergoing advancements at a fast pace and technology is being imported from various other fields. One such imported technology is direct metal laser sintering technology for casting metal crowns.

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.

 

DLMS requires three inputs: material, energy and CAD model.

The material used is powder-based working material. DMLS crowns have a primary composition of chrome cobalt alloy, molybdenum, tungsten, silicon, cerium,  manganese and carbon are the other ingredients used. They are nickel and beryllium free. The material is a mix of particles of the size of 3–14 μm.

 

Energy used is a high powered laser beam (200 W Ytterbium fiber optic laser). This energy is used to melt the alloy powder.

 

CAD model is the machine reads in data from a CAD drawing and lays down successive layers of alloy powder and in this way builds up the model from a series of cross sections. These layers, correspond to the virtual cross section from the CAD model and are joined together to create the final shape.

 

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.
