A Digital Apex Locator for identifying the exact working length of the root canal.

1. A Digital Apex Locator for identifying the exact working length of the root canal. Implementing digital technology, a maximal indication of the file location is displayed by the easy to read LEDs. Digital technology allows a measuring tolerance of 0.1 mm in the apical region.

2. Innovative technology enables you to improve performance of root canal treatments while controlling the entire process. The device’s high sensitivity to minute movements of the file gives you complete control of the measurement.

3. TheApexNRG-XFR overcomes typical weaknesses in root canal treatments: The uncertainty of the exact file location in the root canal. Concern about perforation of periapical tissue. The patient's exposure to unnecessary and excessive x-rays. Root canal procedure weak points

4. Studies show that a successful root canal treatment is directly dependent on the quality of the cleansing of the root canal. The apical third is also the area which usually has a high concentration of bacteria, in addition to being the most difficult to reach using disinfectants. It is important to clean and shape the apical portion and to use a reliable, high resolution measuring device. Therefore, the accuracy and reliability in pointing the working length in the range of 0.5 - 0.0 mm is of utmost importance. Importance of accuracy and resolution

5. Apical Constriction Gutta Percha Past Apex! Importance of accuracy and resolution Using the ApexNRG-XFR can significantly increase the success rate of root canal treatments, especially when compared with reliance solely on x-rays. In the picture to the left, please see what can happen when an x-ray image determines the file to be at the apex; in truth the file has already perforated the apical tissue, which may lead to an infection and require a re-treatment. As the x-ray is a two-dimensional image, there can be a significant difference between the roentgenical apex and the biological apex – between 0.20 - 3.80 mm(Gutierrez and Aguayo 1995). Same tooth, X-ray and actual: X-ray image is long!

6. Measuring Principle Advanced digital technology based on proprietary firmware decodes the signals returning from the root canal as a result of the electric stimulus sent towards the apical constriction.

7. Advantages of Digital Measurement The proprietary algorithm continuously translates the data received via micro-electrical signals, refreshing the display constantly so that each minute movement of the file is read in real time The innovative Digital Signal Processing allows the data to be processed in hundredths of a second, giving the user high sensitivity and complete control of the measuring process, with a maximal tolerance of 0.1 mm in the apical region.

8. Importance of accuracy and resolution Use of DSP technology continuously calculates new data received from the canal. Due to the increased sensitivity, the LEDs continuously display information. This is especially true when the file is first inserted into the canal. The XFR will calculate the exact location, giving a full LED display until the file’s location is verified. The LEDs then continue to display only the sequential movements of the file. Therefore, the file must be moved in slow, methodical movements, something that is less critical when using other, non-digital devices, which usually have a lower resolution of display.

9. The file’s progress is marked by 8 LEDs distributed every 0.25 millimeter, showing the length of the root canal clearly and directly on the user friendly display. The two-way display enables the user to view the results easily and conveniently from any angle. Xtra Fine Resolution for maximum control of the procedure.

10. Reliability of Display The file reaches the apical constriction. Using the ApexNRG-XFR with digital technology, a maximal indication of the file location is displayed, with a measuring tolerance of 0.1 mm in the apical region. The root canal is optimally cleaned right up to the apical constriction, without fear of perforation of the periapical tissue. Apical Constriction

11. Automatic adjustment of the measuring current to changing conditions Accurate location of the apical constriction in changing canal conditions, including dry, wet and bleeding canals, through unique automatic adjustment of the measuring current. Other devices usually use a precalibrated current, which addresses only the average canal condition. This means that if an extraordinary condition arises, the device’s accuracy may be significantly reduced. Dry Wet Bleeding

12. Audible File Location Warning • When the file reaches the 0.5 mm mark, an audible alarm sounds, changing pitch and frequency as the file approaches the apical constriction. • If the apical constriction is passed, the warning signal reaches the highest pitch and frequency, giving a clear indication the file should be pulled back. • This allows you to keep your eyes on the procedure, without having to continuously watch the device.

13. Automatic Calibration MedicNRG's apex locators automatically calibrate, as opposed to comparable devices which need to be manually recalibrated from time to time. Upon turning on the ApexNRG-XFR, the device will perform a self check; you are ready to go!

14. Minimal Size • This compact instrument (36 grams) is easy to • store and easy to manipulate during treatments. • Placement near patient’s mouth, within your line of vision, allowing you to easily and comfortably follow the progress of the file on-line.

15. Short cables prevent external EMI distortions that are typical in long cables, due to weak and sensitive signals that travel a long distance. Short cables are convenient to use in the dental clinic; no more stepping or tripping on long cables. The short cables are also autoclavable, as opposed to comparable devices whose cables are not autoclavable. Short Cables

16. Fully autoclavable accessories including a double set of cables, lip hooks, apron clasps, as well as a mini sensor probe and exclusive mini file holders. Accessories

17. MedicNRG has designed a new type of file clip. Instead of using the bulky, traditional file clip, use our compact Mini File Holder. Reusable – the mini file holder is suitable for autoclave sterilization! Maximizes the limited space inside the oral cavity. Convenient – especially helpful when working on the molar teeth. Compatible with regular and NiTi files Can be used in conjunction with most existing handpieces. Exclusive Mini File Holder

18. Two Options for Power ON The device can be turned on by simply touching the file to the lip hook – no need to press the “ON” button. This is especially convenient when working in close quarters. Small battery. Long life! Easily replaceable battery, using MedicNRG’s drawer system. Expected battery life: 500-600 treatments. The battery is inexpensive and readily available. No need to recharge or plug in the unit.

19. Guarantee: Do you know of another apex locator with a full 50 month manufacturer’s warranty? The electronics are fully guaranteed for this entire period. Reliability
