Obturation cartridges are intended for singlepatient use.Prime the obturation cartridge by expressing a small amount of material before taking it to the tooth.It is constructed of a soft metal and can break or kink. Do not bend or put heavy pressure on the tip of the obturation cartridge.Pre-bend the plugger tip to conform to the curve of the canal.One hundred percent of the consultants would recommend and switch to the Elements Obturation Unit. A slight rotation of the wrist allows the operator to see the gauge that indicates the amount of obturation material remaining in the cartridge. The extruder handpiece is larger and heavier than the System B handpiece due to the integrated motor, but rests comfortably in the hand. Handpiece temperatures remain comfortable to handle during use, and the plugger tips cool almost instantly, preventing accidental injury. The autoclavable aluminum shields are well insulated and durable after repeated sterilization. Cartridges contain enough material to fill an average of 2-3 canals. The medium 23-gauge tips were the most popular size overall. Consultants found the small 25–gauge tips especially useful for filling narrow molar canals. Tip diameters are adequate for all canals. The disposable gutta percha/ RealSeal cartridges are easy to load and heat quickly – 45 seconds or less. The unit is easy to use and provides accurate, dense filling of root canals. The Elements Obturation Unit is well constructed and compact, taking up less counter space than two separate units would. This equipment received a 96% clinical rating. The Elements Obturation Unit was evaluated by eleven consultants and used in over 50 clinical cases. The extruder has two speeds and when extrusion is halted, the plunger retracts automatically to prevent excess material from being extruded. Precise temperature control produces the correct viscosity for material delivery with the touch of a button. Cartridge needles are bent at a 45° angle and are available with 20-, 23-, and 25-gauge tip diameters. The extruder accepts disposable cartridges of gutta percha or RealSeal, a thermoplastic, polymeric obturation material that handles like gutta percha, yet flows at a lower temperature. The five supplied plugger tips, sizes 0.04 to 0.12, fit the original System B. Digital temperature readout of the System B plugger tip is continuously displayed. Each function has pre-set temperatures and durations. The System B handpiece accepts tips for down-packing, hot-pulp testing and cauterizing. The shields may be removed and autoclaved. The handpieces have silicone-covered aluminum shields that help maintain a comfortable temperature to grip. The System B and extruder handpieces are held in hangers mounted on opposite sides of the display unit. The compact unit consists of a tilting polarized liquid crystal display with icons that indicate which of the functions is active. It may be used for filling root canals using the “Continuous Wave of Condensation” or other warm gutta percha techniques. The Elements Obturation Unit is a portable endodontic unit combining the System B heat source with a motorized extruder handpiece. “On three occasions the plastic cap on the GP cartridge became lodged in the unit.”.“It cuts the time to fill a tooth in half.”.
