SLM orthodontic appliances – metal sintering

SLM orthodontic appliances – metal sintering

SLM (Selective Laser Melting) technology enables the manufacturing of metal orthodontic appliances with a level of precision unattainable using conventional soldering or casting methods. Metal sintering allows for the design and production of individual constructions ideally adapted to the patient’s anatomy and the biomechanical assumptions of orthodontic treatment.

Design of SLM orthodontic appliances

The process begins with a digital case analysis based on intraoral scans (STL). The appliances are designed in a CAD environment with consideration given to:

• precise adaptation to tooth surfaces,

• control of the thickness and geometry of individual components,

• the planned direction and magnitude of orthodontic forces,

• the possibility of integration with other appliance elements.

Each design is created individually, exclusively for specific orthodontic indications.

SLM metal sintering in orthodontics

Production is carried out using selective laser melting (SLM) technology, which involves layer-by-layer fusion of metal powder using a laser. This process provides:

• high dimensional accuracy,

• a homogeneous material structure,

• high mechanical strength,

• consistent quality while maintaining the individual character of each appliance.

SLM metal sintering eliminates many of the limitations associated with traditional laboratory techniques.

Applications of SLM orthodontic appliances

SLM technology is used, among others, in the production of:

• custom orthodontic bands,

• soldered components and skeletal constructions,

• appliances supporting orthodontic treatment requiring high stability,

• advanced hybrid solutions combined with other techniques.
