Uses in dentistry
Since 1995 ALPHA LASER welding machines have been successfully applied in dental technology. The newest models VL 50 and ALS 100 are the result of constant technical developments.
Among other applications, ALPHA LASER welding machines are used for manufacture and repair of implant constructions, in crown and bridge technology, in orthodontics, in combined work as well as in partial denture.
The laser reduces the working time in dental restorations by up to 80% in comparison to alternative methods of soldering. The pin point accuracy of the laser beam even makes weldings possible that have to be performed directly next to ceramic facings or plastic teeth. Since the heat-affected-zone is limited in laser welding, intensive finishing work is reduced.
The application of ALPHA LASER welding machines makes efficient joining possible, without the use of solder, thus retaining the corrosion resistance of the basis material.
The result is a stable and biocompatible welding joint.
Examples of applications

Biocompatible dentures thanks to electroplating.
Laser welding guarantees a reliable joint between crown and cast-bridge-members.

Repairs and widening in model castings are performed easily and quickly by means of efficient use of laser technology.
Facings and saddle bridges can remain attached while carrying out weldings, due to the pin-point precision and limited heat-affected-zone. Thus valuable time for the dental technician is saved.

By changes in the occlusion or if contact is not achieved on all points, the laser helps to add missing material quickly and securely. After this process no color difference will be noticeable. The filler wire used for this application is made of the same alloy as the crown itself.

If crown edge extensions are required, laser is the proper tool for a high quality solution without needing to start manufacture from scratch again.

Titanium implant posts can be welded tension-free, using an optimum shielding gas.
The new Argon nozzle ensures the best possible delivery of shielding gas to the area being welded.
