Australasian Dentist Issue 89

50 AustrAlAsiAn Dentist selecting either mist or jet spray at the flick of a switch with the world’s first two- way spray technology. On trial the majority of dentist who have not converted to electric motor handpieces, Fitzgibbon states, are those who have yet to trial and experience the system for themselves. He believes the portability of the nsK nlZ-e unit presents a unique opportunity for dentists in this category. “it is very easy to temporarily install the compact nlZ-e into a dental practice for a trial period,” he says. “it gives dentists a chance to test the much talked about red-band technology and see the advantages for themselves.” Dentists can catch the nlZ-e in action at the ADA training Centre, where two units have recently been installed. “the nlZ-e is ideal for pre-clinical training and may be retrofitted into any existing training facility. it works with almost any dental handpiece on the market, delivering precise and constant speeds to ensure everyone is working to the same training standards,” Fitzgibbon adds. W hile air-powered handpieces are still commonly used in our dental offices, dentistry is trending towards the electric variety. the tangible benefits of using an electric handpiece, with its consistent torque that delivers quiet and efficient cutting, have certainly not gone unnoticed. For those contemplating a conversion, handpiece manufacturer nsK has launched their latest nlZ range of electric micromotors, which makes it easier for users of air driven handpieces to board the electric bandwagon. Game-changing technology the nlZ-e electric micromotor was unveiled during the ADX Melbourne show in May. the “e” stands for endodontics, meaning the nlZ-e motor system can be used across a variety of dental restorations, prophylaxis and endodontic rotary and reciprocating procedures. According to Phil Fitzgibbon, Managing Director of nsK Oceania, the nlZ-e represents convenience, versatility and game-changing technology. “it gives you the flexibility to change a standard air operated piece of dental equipment like a dental chair and dental cart into a fully functional electric unit,” he says. the nlZ-e can be connected to a dental unit with isO 9168-compliant chair line type 2 Midwest 4 holes or type 3 Midwest 4 holes with optics. “if you have a basic air motor on your existing dental chair, it can be removed with a very simple installation process and upgraded to a state-of-the art, brushless electric motor system.” A typical installation takes roughly about 30 minutes to an hour, he adds, depending on whether a technician does it or dentists were to set it up themselves. the small footprint and lightweight design makes the nlZ-e highly configurable to suit your clinical environment. no matter your preferred style of installation, it takes up very little room – sitting on your instrument or operatory tray or mounted to an extended arm. The cutting edge Don’t let its compact size fool you though, because this electric micromotor packs a punch. touting high-speed rotations from 100-40,000 rpm and a maximum torque of 4.2ncm – one of the highest in the market – the high-end nlZ-e is compatible for use with all contra-angle handpieces. “the high end speed is compatible with all red-band 1:5 speed increasing handpieces – especially with the nsK ti-Max Z95lsW with aerosol spray adjustment,” Fitzgibbon adds. Considered the Ferrari of handpieces, red-band handpieces deliver notably smoother and quieter cutting action. According to Phil, the 1:5 speed increasing handpieces can be used in conjunction with the nlZ-e running at 200,000 rpm. the nsK ti-Max Z95lsW red band handpiece lets users control aerosols by Need for speed HanDpIeCe teCHnology NSK’s latest electric micromotor promises high-speed rotations and massive torque for efficient cutting, not to mention, quick conversion for air driven systems.
