Erbium Yag Laser Device for Oral Surgery

The first introduction of lasers in dentistry occurred a few decades ago when they had a DIODE or CO2 energy source and varying wave lengths. The scope of these devices was restricted to the soft tissues. Many dentists feared causing damage to adjacent tissues due to inconsistent control over the beam.  In addition, its use was not encouraged by the limited indications for lasers in dentistry and oral surgery at the time.

More than a decade ago, a new, innovative type of laser entered the marketplace - the Erbium Yag laser - which has a different wavelength and a beam which is absorbed in water: this makes it more useful in our field, namely for its potential for use on soft tissues (gum tissue) as well as hard tissues (teeth and bone).

The ERYAG laser device has in recent years met with positive findings in numerous research studies: these have provided scientific evidence of its effectiveness in the treatment of periodontal disease by means of its decontaminating properties, enabling complete disinfection of periodontal pockets and infected extraction sites.

The dentist is able to vary the direction and power level of the beam as well as the wavelength frequency, similar to the way a sculptor varies the angulation and force of tools on his sculpture. It can also be used for shaping bone in oral surgery and bone grafting. A possible expanded application for it in general dentistry is the removal of caries by a minimally invasive method.

One of the more important uses of lasers is in the treatment of peri-implantitis (infection of the gums surrounding implants): due to the beam’s ability to clean the infected surface area of implants, the tissues surrounding the implants (gums and bone) are allowed to heal under optimal conditions.

The laser device has become a tool of great importance in present-day surgery as a result of its great precision combined with its minimal involvement of adjacent tissues.

The advantage provided by the laser beam, which functions at different tissue depths, over conventional mechanical methods is even more pronounced when the laser is used in combination with the operating microscope….
