The primary difference between Soan and SleeperOne is their power sources. Soan is a wireless device whereas Sleeperone is a corded device. In addition, Soan offers two injection speeds, high and low, while Sleeperone has three speed options: slow, medium, and fast. The only difference between these settings is that for the SleeperOne the medium speed is indicated for intraligamental injections whereas for the Soan these injections can be performed under the "low" setting. While SleeperOne's only setting adjustment is the injection speed, Soan offers the following additional customizable settings: sound management (on/off), time before shutdown, and mode of operation of injection pedal (cruise vs drive).
It is possible to perform intraosseous anesthesia with SOAN (in children, same with SleeperOne). With SleeperOne⑤ and Soan, it is not possible to deliver an intraosseous anesthesia for adult patients. However, many dental professionals use it for delivering intraosseous anesthesia in primary and mixed dentition. Since children’s cortical plates are softer, SleeperOne⑤ and Soan can easily manually penetrate the cancellous bone in order to deliver the anesthetic very close to the apices.
All metric-style dental needles can be used with the devices. For maximum efficiency, it is recommended to use Effitec Needles®. Their unique scalpel bevel edge, incises the tissues without tearing them, making the penetration easier for the dental professional and painless for the patient.
SleeperOne⑤ and Soan are electronic injection pens designed to effectively replace your manual syringe. With these devices, your protocols will not change and you will perform all of your anesthesia injections painlessly and with greater comfort thanks to the progressive diffusion of the anesthetic solution into the tissues.
The wireless pedal allows the dental professional to initiate the injection. This remote control enables a real pen grip and better support points for maximum precision when holding the needle.
Intraosseous anesthesia techniques have existed since 1906, evolved in 1997 thanks to Dr Alain VILLETTE, and were perfected in 2007 by Dr Eric Pasquier.
The Intraosseous protocol is made up of 3 steps, after initially delivering an anesthesia in the attached gingival tissues (periosteum), a perforation is performed, via the septum, towards the apices. The bone is not innervated, the perforation is therefore completely painless. Once the needle has penetrated to 3/4 of its length, the injection can be delivered in the highly vascularized cancellous bone close to the apices. One can deliver a complete cartridge of anesthetic with highly concentrated vasoconstrictor, without any risk of ischemia / necrosis. The anesthesia is immediate (proximity to the apices) and without the risk of failures (in the center of the cancellous bone, close to the apices). The solution diffuses in the bone, anesthetizing up to 8 teeth depending on the volume injected, and eliminates collateral numbness.
Electronic injections can be performed on children with the use of a shorter Effitec Needle®. The advantages are the same as for adults: effectiveness, immediate action, and painless. Thanks to the pen grip of the devices and Effitec Needles®, in the majority of cases, only slight pressure is required to penetrate the cancellous bone. The absence of collateral soft tissue numbness is an additional feature that eliminates the risk of self-biting for children assuring the safety of your younger patients.
Our devices adapt the speed of injection for better control and therefore less pain. Various injection modes are available on our devices, for optimal patient comfort.
A selection of needles of different sizes and diameters were selected to match your needs and are included with your device. All Effitec Needles® have a patented scalpel bevel blade design to incise the mucosal surface painlessly. They are made of a siliconized stainless-steel tube that effortlessly slides into the tissues.
Depending on how it is used, the needle design will influence whether the injection is painless or not as well as the success or failure of the anesthesia itself. For every injection, the dental professional’s first consideration is avoiding pain upon needle penetration. Standard dental anesthesia needles (triple bevel) penetrate the tissues by stretching and tearing them and thereby creating tensions that generate pain. The most recent generations of needle (double bevel) incise the tissues, like a scalpel. They liberate the tensions and therefore, can be painless. However, these needles must be used correctly [7] the double bevel which renders a blade enables the needle to penetrate deeper into the ligament to solve the problem of recurrent leakages with intraligamentary anesthesia. The double bevel, combined with the thicker lining of the needle, eliminates needle deflection, which is the main reason for the failure of ID nerve blocks.
For each anesthesia technique, a specific needle is available which reduces the pain and improves the results.

As with any type of dental needle and anesthesia technique, the needle can break if the instructions for use are not followed (cf. user guide).
All Effitec Needles® are single use. It is recommended to change the needle between injections to ensure top performance of the needle and the safety of the patient.
