Numbee: Needle-less Dental Anesthesia Delivery System


The NumbeeThe Numbee Needle-less Dental Anesthesia Delivery System allows practitioners the ability to delivery rapid onset of localized ("single tooth") anesthesia without using a needle or conventional injection techniques. The Numbee system utilizes a patented and innovative designed tip that allows for an atraumatic PDL injection that is comfortable for the patient and prevents any damage to the ligaments or the cementum of the tooth. With Numbee, the numbness for the patient is confined to a single tooth eliminating the common discomfort for patients with numbness to their lips, gums and cheeks. The duration of anesthesia with a PDL injection using NumBee is comparable to an infiltration with a duration of approximately 35-45 minutes.
 
No patients like needle injections, this we know. You've seen the range of emotions in your patients from mild uneasiness to absolute fear. Your patients will generally not tell you the fear or discomfort they experience relating to an injection as it is considered an acceptable aspect of the dentist. However, it is a fact many patients avoid seeing the dentist simply to avoid the "needle." Regardless of how refined your injection technique is, the Numbee is a unique and simple solution that will eliminate your patient's injection anxiety and discomfort as they do not see any use of a needle, which will ultimately lead to happier patients, more frequent visits and increased referrals. You owe it to your patients to provide them ease of mind with this needle-less dental anesthesia delivery system.

Beyond patient comfort, let's face it, this is not a practitioners favorite aspect of their professions and anything that is an adjunct to this process that helps is a positive. Numbee will also allow you the ability to work more efficiently. Numbee allows for rapid onset of anesthesia and dental work can begin immediately after administration. This saves you time and time is money in your practice. With Numbee you will also use a significantly less anesthetic dosage leading to lower chances of toxicity and less material expense.

Numbee is a perfect solution for your pediatric patients or needle phobia patients. Perfect for hygiene scaling, crown prep, filings, etc. For longer or more invasive procedures you will likely still have to use conventional methods based on the duration of the Numbee system.

No. If you can screw a standard dental needle on the device in question, then you can use the NumBee with that device. However, with this said, studies have shown that patients respond more positively when our Numbee intraligamental syringe is utilized as patients associate a conventional looking syringe with a needle. For the most effective patient experience and easier administration using Numbee we recommend using an intraligamental syringe with the Numbee tips, but it is not required or necessary to utilize the Numbee system.
Prior to use, it is advised to explain to the patient the following to alleviate their uneasiness.
  1. There is NO Needle. Explain that you use an innovative injection system in your practice, where no needle is used which they may be accustomed to receiving with past dental experiences so they can relax and not worry about an injection using a needle.
  2. That the Patient Might Not Feel Numbness, but you will of course ensure they are numb prior to starting any procedures (validate with cold-testing the target tooth if necessary).
  3. Post Procedure that the patient should generally not have facial, lip or tongue numbness, which makes the anesthesia technique you utilize more comfortable for the patient and that it lasts for a shorter duration of only around 35-45 minutes.

  1. Remove Numbee From its Pouch. Remove the yellow plastic tube by pulling on it or twisting it out. DO NOT attempt to remove it by snapping it laterally as this will bend the cannula and render the Numbee Tip not usable.

    Note: Numbee Tips are one time use per patient and can be used for multiple applications for the patient at the same visit time.
  2. Loading Syringe & Numbee Tip. Load the syringe with your standard anesthetic carpule. Then insert the metal cannula on the Numbee Tip into the syringe to penetrate the carpule. Securely screw the Numbee Tip onto the syringe.

    Note: The Numbee Tips can be used with any conventional syringe with a standard screw attachment. Please consider using the Numbee intraligamental syringe.

    Note: Numbee works with any anesthetic solution.
  3. Squeeze Plunger on syringe to check and make sure the anesthetic is being expressed. The use of topical is optional and delivering a small amount of anesthesia from the Numbee Tip into the gingival may suffice without topical.
  4. Articulation of Numbee Tip. If you wish to articulate the tip, look at the blue tip and find the side with a slight notch. This is the bottom. The Numbee Tip can only articulate from the top to the bottom. If you force the Numbee Tip in the opposite direction, you may break the cannula inside and render the Numbee Tip not usable. See Diagram A.

  5. Start Buccal PDL Injection. Place the Numbee Tip on top of the gingiva with the tip contacting the tooth at 90 degrees. Dispense a few drops of anesthetic to start numbing the gingiva in the area of entry. See Diagram B.

  6. Rotate the Tip inwards and enter the sulcus, using the tooth as a guide.
  7. Insert Tip Into the Sulcus until you meet resistance from the PDL. Do NOT penetrate or puncture the PDL. See Diagram B.
  8. Using Slight Pressure, create a seal between the tip of the Numbee Tip and the PDL.
  9. Slowly, Exert Pressure on the plunger to infuse tissue with anesthetic. If you are using the Numbee intraligamental syringe each squeeze of the lever delivers approximately 0.06ml of anesthetic and takes 10-15 seconds. Typically, two squeezes of the lever on the Numbee syringe per injection site is sufficient, but more anesthetic may be required for longer or more invasive procedures. If you are using a conventional syringe, dispense approximately 0.12ml of anesthetic per site.

    Caution: Do not attempt to puncture the ligament to deliver a bolus of anesthetic fluid, rather allow the anesthesia to be absorbed slowly by the ligament under pressure.

    Note: If anesthesia will not express, reduce the pressure against the PDL. If anesthesia if leaking from the sulcus, increase pressure on the Numbee Tip to create a better seal against the PDL and reduce the pressure on the syringe plunger for a slower delivery of anesthetic.

    Note: Blanching of the tissue at the target tooth should be visible while feeling back pressure. Partial blanching of the tissue at the adjacent teeth is common.
  10. Repeat Application on Mesial and Distal Papillae.

    Note: Anesthetic can also be placed in the buccal and lingual sulcus as needed. For suggested application locations please see Diagram C.

  11. After Use Dispose of the Numbee Tip and place in sharps disposal container.
