VCU - NL9000 Handpieces

  1. 1. Brasseler USA and VCU School of Dentistry Handpieces Ian Pryor – Key Account Manager
  2. 2. NL9000 Introduction <ul><li>High speed handpiece </li></ul><ul><li>Solid titanium </li></ul><ul><li>Swivel quick-disconnect </li></ul><ul><li>Fiber optic </li></ul>
  3. 3. <ul><li>The Features: </li></ul><ul><ul><ul><li>Four Port Water Spray </li></ul></ul></ul><ul><ul><ul><li>New Air Pressure Regulating Valve </li></ul></ul></ul><ul><ul><ul><li>Ceramic Ball Bearings </li></ul></ul></ul><ul><ul><ul><li>Clean Head System </li></ul></ul></ul><ul><ul><ul><li>Cellular Glass Optics </li></ul></ul></ul>
  4. 4. Ceramic Ball Bearings <ul><li>About 50% lighter than Stainless steel ball. </li></ul><ul><li>Less centrifugal force upon the Retainer Ring. </li></ul><ul><li>About 25% harder than Stainless steel ball. </li></ul><ul><li>Higher tolerance for scarring and deformation. </li></ul><ul><li>This provides for a smoother rotation, which results in quietness, accuracy, and longer life. </li></ul>Weight comparison (Stainless steel vs. ceramic) Hardness comparison (Stainless steel vs. ceramic)
  5. 5. Clean Head System <ul><li>Why is the Clean Head system Needed? </li></ul><ul><li>When the foot pedal/rheostat is released and air supply is terminated, the bur in a handpiece will spin to a stop (not instantaneously). </li></ul><ul><li>The turbine rotation under no air supply </li></ul><ul><li>generates negative pressure (vacuum) and draws </li></ul><ul><li>foreign matter (fluid, debris) upwards into handpiece head. </li></ul><ul><li>Benefits of the Clean Head System </li></ul><ul><li>Distributes such foreign matter away from the head of the handpiece. </li></ul><ul><li>Reduces post-operative contaminants in a handpiece and extends turbine and cartridge life. </li></ul>
  6. 6. Cellular Glass Optics <ul><li>Cellular Glass Rods offer: </li></ul><ul><li>Brilliant Illumination </li></ul><ul><li>Highly Durable </li></ul><ul><li>Longer Lasting Under Repeated Autoclaving </li></ul>
  7. 7. How the NL9000 Measures Up <ul><li>Power – The highest torque in a turbine handpiece. </li></ul><ul><li>Lightweight - One of the lightest weight handpieces ever. </li></ul><ul><li>Low Noise - Extremely low noise in a turbine handpiece. </li></ul><ul><li>Brand K – KaVo </li></ul><ul><li>Brand W – W&H/Adec </li></ul><ul><li>Brand M - Midwest </li></ul>
  8. 8. Powerful 17 watts - Mini Head 21 watts - Standard Head 22 watts - Torque Head <ul><li>Innovative twin nozzle drive air system </li></ul><ul><li>Uniquely designed rotor </li></ul><ul><li>Open style turbine </li></ul>
  9. 9. Lightweight <ul><li>Milled from Solid Titanium </li></ul><ul><ul><li>Titanium has the highest strength-to-weight ratio of any metal </li></ul></ul><ul><ul><li>As strong as steel but 45% lighter </li></ul></ul>
  10. 10. Low Noise <ul><li>Turbine Designed to maximize power while minimizing noise </li></ul><ul><li>Pressure regulating valve maintains consistent pressure eliminating excessive speed fluctuations. </li></ul>
  11. 11. Basic Set up <ul><li>Connects to Standard 5 and 6 hole tubing using a quick disconnect coupler </li></ul><ul><li>42 psi is the optimal air pressure to achieve peak performance </li></ul>Optic Drive air Spray water Exhaust air Spray air Optic Drive air Spray water Exhaust air Spray air 6-pin 5-hole
  12. 12. Basic NL9000 Manual Maintenance <ul><li>Remove bur from the NL9000 </li></ul><ul><li>Run under warm water and clean softly with a toothbrush. </li></ul><ul><li>Attach proper nozzle to PANA spray can (this nozzle came in the package with your handpiece). </li></ul><ul><li>With nozzle attached insert into the rear of the NL9000 and spray for approximately 2-3 seconds or spray until lubrication comes out of the head. </li></ul><ul><li>Purge the NL9000 of excess spray either via an air station or by returning to the operatory and placing the handpiece back on its coupler. </li></ul><ul><li>Bag and Autoclave. </li></ul>
  13. 13. NL9000 Automatic Maintenance Remove bur from the NL9000 and wash handpiece down to remove external debris Place theNL9000 in a Care3 Plus system and close the door Select “S” or Short Cycle and Press Start Care3 Plus automatically cleans and lubricates handpiece Bag and then autoclave
  14. 14. Seating and Removing the Bur <ul><li>Seating the Bur </li></ul><ul><li>Place the bur into the chuck. Press the push button and insert the bur into the chuck until it is secure. </li></ul><ul><li>Make sure that the bur is secure by </li></ul><ul><li>pushing and pulling the bur. This can also increase the chucking power. </li></ul><ul><li>Removing the Bur </li></ul><ul><li>Press the push-button firmly and remove the bur. </li></ul><ul><li>Make certain the bur has stopped rotating before attempting to remove. </li></ul>
  15. 15. Changing the O-Rings <ul><li>Over a period of time it is possible for water to leak from the coupler joint. If this occurs replace the o-rings as a complete set. </li></ul><ul><li>Simple Steps </li></ul><ul><li>Remove the handpiece from the coupling, loosen and remove the taper ring. </li></ul><ul><li>Push out the worn O-ring with your thumb. Insert new O-ring in the O-ring groove. </li></ul><ul><li>Securely tighten the taper ring. </li></ul>
  16. 16. <ul><li>If fiber optic light is less intense debris may be blocking the glass rod. </li></ul><ul><li>Simply wipe clean the Cellular Glass optic face with alcohol-immersed cotton swab </li></ul><ul><li>Do not use any abrasive as it may damage the cellular glass rod </li></ul>Cleaning the Glass Rod
