Lasers have become an indispensable part of modern medicine. Laser systems are also becoming increasingly important in dentistry. The non-contact work is gentle on tissue, biostimulating, reduces bleeding, pain and germs, in short, it is less invasive.
In order to meet the specific application possibilities, 4 different lasers are used in our dental office.
Why are different types of lasers useful?
There are different types of tissue in the mouth. These include the gums (gingiva), bones and the tooth. The latter, in turn, consists of different layers. The visible and at the same time hardest substance of the entire body is the enamel. The underlying dentin is much softer. The nerve (pulp) is found in the inner part of the tooth. Each laser has a specific wavelength. This must be chosen in relation to the tissue to be treated. There is no one dental laser, but rather various types of lasers. These differ in their mode of action and absorption behaviour.
Soft lasers are used, for example, to accelerate wound healing and for wound healing disorders. They cause bio stimulation, which strengthens the self-healing powers.
Diode laser 670nm wavelength
- The low level laser is used for bio stimulation, e.g. after tooth removal, gum pocket treatment, vital preservation of weakened tooth nerves, and surgery. This results in better, quicker wound healing, and painless, complication-free ingrowth of implants, without swelling.
- Another application is the antimicrobial photodynamic therapy for bone loss (periodontosis). This is also painless and, more than almost any other method, guarantees a clear and, above all, lasting removal of the germs in the pockets. The bacteria responsible for the inflammation are marked with methylene blue and made harmless by the laser. At the same time, surrounding tissue is biostimulated. This therapy contributes to the reconstruction of a healthy retaining apparatus (bone) overall. Antibiotic administration can thus be dispensed with.
- Laser acupuncture prevents fracture irritation during impression taking.
Hard lasers achieve extensive tissue modification, removal, decontamination and sterilization due to their energy and wavelength.
Er:yag laser 2940nm
- This laser is used in conservative filling therapy. Caries is removed selectively and gently. Exposed dentin and enamel are decontaminated and sterilized. Plastic fillings are given better adhesive strength and thus have less tendency for secondary caries. The use of abrasive diamonds is minimized or eliminated. Unpleasant vibrations are eliminated due to non-contact working. Fewer anesthetics are needed, and in the best case no anesthetics are needed at all. The treatment time, especially for cervical fillings, is shortened.
- The erbium yag laser enables immediate implantation, despite chronically inflamed tissue, directly after tooth extraction. Bone is also selectively decontaminated and sterilized after mechanical cyst or granuloma removal. This property makes it the favorite of our dental office.
Co2 laser 10600nm
- Its application is in the treatment of the “soft parts” and the reduction of germs. The remaining wound surface normally does not need to be sutured. Thus, needles and sutures can be dispensed with. There is significantly less subsequent inflammation and pain. The treatment is virtually free of bleeding. The wound is also largely insensitive to touch and there are smaller scars.
- We try to keep the teeth vital whenever possible. In the case of deep caries near the nerve, the surface is treated with the co2 laser (indirect capping), thus avoiding root canal treatment.
- Cold-sensitive tooth necks are desensitized in the long term.
- The practitioner has the advantage of maximum precision control during guidance in all 3 dimensions.
Diode laser 810mm
- We use this laser to shorten the often lengthy root canal treatments: If the nerve in the tooth is inflamed or necrotic, it is removed and the canal is cleansed. The purpose of this is to remove the bacteria-infested tissue to the extent that a tight filling of the root canal becomes possible. Most of the time, the bacteria cannot be removed in one session. Therefore, a drug is introduced into the root canal. This process may be repeated before the treatment is finally completed. The diode laser saves treatment steps. The laser light kills off the bacteria. This eliminates the need for second or third appointments. The tooth can be sealed immediately.
- In the case of gingivitis, the resulting gingival pockets and the root surfaces must be thoroughly cleaned. The use of the diode laser also eliminates the bacteria (biofilm) here. The healing process is faster, with no bleeding, as the blood vessels are closed off. Pain after the treatment is usually eliminated.
