General operation In KEY Laser, the laser beam is not directed by a rigid articulated mirror arm system, but is passed via a flexible instrument tube with internal fibre to the treatment site. The fibre instrument tube, slim handpiece dimensions, variable laser parameters and the integrated spray supply, enable the user to handle the KaVo KEY Laser in an ergonomic way. Bibliography More than 230 scientific studies confirm the indications for the KaVo KEY Laser (pdf, 58 kB) General information on the diode LASER The diode LASER is minimally invasive and has a series of advantages over conventional treatments (such as electrosurgery):Reduced bleeding during surgery  Fewer sutures  Less postoperative swelling  Less scarring  Bactericidal effect of the LASER  Less need for antibiotics and antiphlogistics  Less pain and controlled wound healing Would you like to learn more about the KEY Laser 3 + ? Or set up an appointment with us? Or participate in a laser seminar? The new KEY Pulse technology The new KEY Pulse technology was developed especially for perfect removal in all indications. Through the short pulses (S-pulses, SP), you achieve double the performance with the same pulse energy. As a result, you can remove hard tissue at very high speeds. When optimising the system, great efforts were made to find the ideal balance of peak pulse performance and therapeutic success. An additional advantage: The lifespan of optical components is significantly increased through KEY Pulse technology. Optimised high performance for all indications. New range of indications in laser treatment A leader in LASER safety as well. With the new, light safety glasses, KaVo sets standards in Laser safety as well Ergonomically shape very light polycarbonate glasses combining high wearing comfort with sporty design optimum fit maximum eye protection   For reduced fatigue and concentrated treatment, even at the end of a long day. All the possibilities of a diode laser High precision surgery and soft tissue managementMinimum bleeding enabling a better view in the surgical fieldMinimised scar formationMinimised postoperative wound pain, scarcely any swelling Decontamination of the irradiated tissueEffective protection from infections Periodontics - closed curettage Removal of subgingival concrement Removal of junctional epithelium Germ reduction Handpiece P2261 Applicators Green wedge Black wedge Blue wedge Blue wedge, short Green cone Yellow periimplantitis - cylinder Yellow periimplantitis cylinder, short Red surgery cylinder The high-speed effect With shortened pulses (S-pulses, SP), you can remove hard tissue very quickly at the same pulse energy. Wavelengths All of the diode LASER’s on the market with wavelengths in the near infrared spectrum (810 to 980 nm) are strongly absorbed by melanin and haemoglobin (oxyhaemoglobin HBO2). They are absorbed to a lesser degree by water. These lasers are therefore absorbed in particular by blood itself. Of all of these specific wavelengths, the wavelength of 980 nm is absorbed the most by water. Its effect is therefore not as dependent on the availability of blood vessels in the irradiated area as with other diode LASER’s.

The built-in autopilot provides continuous feedback about the concrement still present, indicated both visually in the display and by an acoustic signal. The LASER is used only as much as necessary and as little as possible. Features Low-pain treatment The pulse duration of the KaVo KEY Laser 3 + is so short that the reaction threshold of the nerves is not reached. There is generally no need for anaesthetics. No vibrations. No shrill drilling noise. Germ-destroying effect KaVo KEY Laser 3 + kills all germs. Owing to the high energy absorption in water of this laser wavelength, the moisture content of the germ cells is evaporated. The cell membrane bursts and the cells thus die. Faster wound healing Operations with KaVo KEY Laser 3 + are automatic, contactless and necrosis-free. So the result is faster wound healing without postoperative symptoms. Laser handpiece 2061 for periodontics Fibre tip rotatable through 360° Moistening with water Exchangeable optical prisms in different sizes for periodontics, surgery or periimplantitis Mountable on laser tube coupling, freely rotatable through 360°     Positive feedback: Gentle treatment thanks to auto-detection Relaxed patients are happy patients. The intelligent approach of KEY Laser 3 + guarantees patient satisfaction. During treatment for periodontitis, even the smallest concretion is detected and removed - reliably and without residue. With selective auto detection, laser activity is focused on affected areas only. Healthy root cement remains untouched by this extremely gentle treatment, which is in the interests of the patient; and also in the interests of maximum efficiency.

The KaVo KEY Laser 3 + feedback system is a quantum leap for dental laser technology. It means that dental science now, for the first time, has an instrument with which critical procedures can be completed more quickly, more reliably and more thoroughly, with the maximum of comfort and no impact on healthy substance. Thanks to the feedback system, concretion can be detected and de-scaled - completely and selectively, even in hard-to-reach areas.

No need for scalers, Tomkins file and special instruments in periodontal treatment. Working "blind" in gingival pockets may now be confidently accomplished. The built-in autopilot provides continuous feedback about the concrement still present, indicated in the display and by an acoustic signal. The LASER is used only as much as necessary and as little as possible. So " flying blind " in the treatment of dental pockets becomes a precisely controlled process: safe, convenient and effective. Studies Comparison of ER:YAG and ER:YSGG Laser ablation of dental hard tissues(only in English, pdf, 304 kB) Study Split-Mouth Follow-Up 2-Year A Planing. Root and Scaling or Laser YAG ER: with Periodontal Treatment (only in English, pdf, 151 KB) And here's how the feedback system functions The 655 nm excitation light is passed into the inflamed pocket by the periodontics handpiece. The pathological substances there send a fluorescent signal to a receiver. This then sends a control signal to the therapy laser and triggers the removal mechanism. When the receiver no longer receives any fluorescence signals, the laser beam is switched off. Safety regulations In general, the LASER safety guidelines in IEC 60825-1 should be observed. Protective LASER goggles should therefore be worn by everybody near the LASER (such as the dentist, assistant and patient). The LASER safety goggles are delivered with the GENTLEray 980. KaVo offers regular LASER courses that enable you to use the LASER with confidence and skill.   The effect For delicate procedures, longer pulses (LP) are available to optimally protect the remaining or native tissue in conjunction with the feedback system.

Conservative therapy Caries preparation Conditioning of enamel and dentine Sealing of fissures Densensitization of hypersensitive tooth necks Handpiece 2060, E2062, K2063 Applicators Free beam Contact tip Surgery tip 50/10   "Lambda One" model The sporty design of the "Lambda One" model offers excellent eye protection for everyone who does not wear prescription glasses. With a profile adapted to the shape of the face, they securely protect the eye region from scattered Laser radiation. The light plastic temples render the low weight of the glasses (approx. 24 g) hardly noticeable, relieving your temple and neck regions all day long. "Dyna Guard" model The "Dyna Guard" model was developed especially for those who wear prescription glasses. With their innovative design, these glasses fit over all customary shapes and sizes of corrective glasses. Again, very low weight (approx. 39 g) was a design requirement for these glasses. The novel temple shape ensures that the protective glasses do not push on the arms of the corrective glasses, thereby preventing tensions and headaches, even when used for a long periods. KEY Laser 3 with feedback system - the state-of-the-art answer to successful treatment A large number of clinical trials have proved that KaVo KEY Laser 3 is a highly effective periodontological treatment, serving to compound the fact that this KaVo technology is unique.

Comparison with the Key LASER The focus of the GENTLEray 980 diode LASER is on treating oral soft tissue with a positive haemostatic effect, and decontaminating irradiated areas as in endodontics, for example. In contrast, the KEY III is suitable for the treatment of soft tissue and hard tissue (enamel and bone), and in periodontology for gentle calculus removal. It therefore has a wider indication spectrum. Immediately ready for use The KaVo KEY Laser 3 + is a self-contained device and requires neither a water connection nor a compressed air connection - immediately ready for use.
