Laser Melting bars

Laser melting technology makes it possible to produce bars that, by connecting the abutments (stump pins or implants), create a removable, but firmly placed, extended prosthesis. The bar, which is custom made, is fixed to the implants and supports the prosthesis allowing to discharge the load even on the mucosa: thus achieving maximum mechanical stability and a full chewing ability combined with a quality esthetic result.

Toronto bridge made via laser melting

There are different types of bars (square, trapezoidal and also Toronto Bridge with a reduced dental anatomy) that allow different insertions and anchors to mobile prostheses; all types of bars are easily made in laser melting because they are present in the libraries of the most popular design software.

Why choose laser melting

Bars made via laser melting

The creation of bars by laser melting is the optimal choice whether you opt for a wire bar, or if you decide to follow the anatomy of the mucosa: in this case it will be possible to assess the optimal reproduction of the ridge. Morpho-functional characteristics will be adapted to the intended use but there will be a significant reduction in production times.

Laser melting also offers consistent, repeatable results, with a high standard of quality. The tolerances achieved by laser melting stratification are perfectly suited to the type of machining.

If we compare a bar in laser melting with one obtained from solid material, we note how these are interchangeable: the level of finishing, surface quality, sturdiness, functionality and possible applications are identical.

Upon designing, however, laser melting bars require a different connection setting.

Design of bars in laser melting

During the design of bars that will be made from solid material, the implant connection is reproduced directly in mathematic algorithms and then it will be possible to insert any type of connection.
The choice of laser melting, on the other hand, leads to a compromise because the use of anti-rotational connections or the insertion of particular geometries are not recommended.

Layers, naturally present in laser melting manufacturing, can create interference in connections; for this reason, it is suggested to be careful and use rotational connections, also suitable for the use of T-base.

Highlights

Custom prosthesis reinforcement bars and meshes

Laser Melting replaces the melting activities that normally engage the dental technician who is preparing to make their prostheses more resistant. Avoiding the equipment necessary for melting, being able to easily and digitally modify the reinforcement before printing, and saving overall time are the main advantages that 3D metal printing offers to reinforcement bars and meshes.
