What is LASER?

laser00

A laser is a device that emits light through a process of optical amplification based on the stimulated emission of electromagnetic radiation. The term “laser” originated as an acronym for Light Amplification by Stimulated Emission of Radiation. Lasers differ from other sources of light because they emit light coherently. Its spatial coherence allows a laser to be focused to a tight spot, and this enables applications like laser cutting and laser lithography. Its spatial coherence also keeps a laser beam collimated over long distances, and this enables laser pointers to work. Laser also have high temporal coherence which allows them to have a very narrow spectrum, i.e., they only emit a single color of light. Their temporal coherence also allows them to emit pulses of light that only last a femtosecond.

Lasers have many important applications. They are used in common consumer devices such as DVD players, laser printers, and barcode scanners. They are used in medicine for laser surgery and various skin treatments, and in industry for cutting and welding materials. They are used in military and law enforcement devices for marking targets and measuring range and speed. Laser lighting displays use laser light as an entertainment medium. Lasers also have many important applications in scientific research. Source: Wikipedia.

Nano

Efficient performance – gentle cutting action – innovative design. That’s what modern diode lasers are all about. The elexxion claros nano is based on the use of superior DPL technology, which opens the way to dozens of soft tissue applications. Painless, efficient and gentle.

The patented pulse technology of the elexxion claros nano combines the benefits of high energy output with the safety and simplicity of a conventional compact diode laser. In addition, the ultra-short pulse duration of 16 μs permits thermal relaxation of target tissue, which keeps undesirable tissue damage to a minimum.

The combination of high output power and extremely short pulses makes it possible to achieve exceptional cutting speed and precision. The patented pulse technology also prevents virtually all tissue carbonization and as a result shortens recovery time.

The wavelength of 810 nm ensures outstanding results in terms of coagulation.

Laser Dentistry – Clinical Application

Laser-Dentistry

laser00

Dental lasers are now being used in all fields of dental disciplines from oral surgery , restorative dentistry in caries removal and tooth preparation , cosmetic dentistry in soft tissue contouring and osseous crown lengthening to periodontology and endodontics in bacterial decontamination and associated surgical treatments. Most recently, researchers are looking into the application of lasers in implant dentistry and treatment of peri-implantitis.


Laser in Oral Surgery

Oral Surgery

Surgical procedures with the diode laser are often bloodless and pain free. These are very desirable attributes for both the dentist and patient.

1. Surgery General – the laser is working at its highest power level

2. Treatment of Abscess – A localized periapical or periodontal abscess

3. Apthous Ulcer Therapy

4. Hemostasis – bleeding following any dental surgery procedure.

5. Curettage – Treatment of advanced periodontal disease 6-10mm.

6. Epulides – Epulis Fissurata all biotypes from granulomatous to giant cell, and fibrous.

7. Irritation Fibroma – Fibromas of the tongue, lip, cheek, and gingiva.

9. Gingivectomy prior to impression or cad cam crown – excess tissue needing removal prior to crown impression, cosmetic recontouring.

10. Granuloma – granulomatous tissue present necessitating removal.

11. Hemangioma – hemangiomas of the lip cheek or tongue as well as blue or venous lake lesions

12. Removal of Hyperplastic tissue – any type of hyperplastic tissue.

13. Bacterial Reduction – any surface area needing reduction of bacteria.

14. Flap surgery – any area requiring a bloodless flap where compromised vascularity is not an issue, for example a split thickness flap for a connective tissue graft is not an area where the laser should be used.

15. Excisional biopsy – any tissue requiring removal that is indicated for a pathology report.

16. Retention cyst – any retained cystic tissue.

17. Exposure of Impacted Teeth – removal of impacted teeth or exposure for orthodontic purposes.

18. Edentulous ridge – removal of excess tissue for preprosthetic surgery.

19. Seeping hemorrhage – areas of persistent bleeding.

20. Sulcus preparation – preparing the sulcus for impressions for crowns or for cad cam images for crowns.

21. Verrucae Lesion – Removal of all Verrucae, wart like and papillomatous lesions.

22. Vestibuloplasty – Ill fitting dentures due to high muscle attachments.

23. Root end rescetion – Failed endodontic treatment needing endodontic surgery (apicoectomy/apicesectomy).

 


Laser for Gum Treatment

Periodontology

The diode wavelengths have desirable characteristics for periodontal therapy because of an excellent bacterial decontamination rate of 99.6%

1. Pocket treatment – periodontally generated pain

2. Gingivectomy – excessive gingiva, sufficient attached tissue and biologic width is needed.

3. Internal bevel incision – swollen gingiva, excessive pocket depth that will not resolve with conservative treatiment.

4. Bacterial reduction – mild to advanced periodontal disease accompanied by bleeding and or bone loss.

5. Decontaminate membranes – any surface which is in need of bacteial decontamination.

6. Open curettage – Pocket depth in excess of 7 mm where access and visualization of calculus for removal is
necessasary.

7. Pocket reduction – excessive pocket depth or a need to remodel the gingival architecture to a more favorable state where the attached gingiva is sufficient for removal, ie.the hard palate

 

Laser for Endodontic Treatment

Endodontology

Diode lasers provide excellent bacterial reduction in endodontic canals. The laser offers much better reduction than other means. Investigation of the dentinal tublii shows bacterial contamination up to 1,100μm in depth. Chemical decontamination produces activity up to only 100μm. Diode lasers will produce complete decontamination up to 1,000μm.

 


Laser for Teeth Whitening

Bleaching

A treatment which gets much more famous to every year in aesthetic dentistry is bleaching.

 


Laser in Dental Implant

Implantology

 

Low Lever Laser Therapy

Other

The therapy laser (LLLT – low level laser therapy) is a good instrument for a pain reduction, better wound healing and a bio-stimulation.

 

Special Laser Therapy – Depigmentation

Pigmented gums or lips can be treated with laser.
