Injecting anesthetic in the standard inferior alveolar nerve block is a classical practice for dentists. But in numerous cases, the lack of clear anatomical landmarks makes the injection uneasy.
Dentalgic has developped and patented EZ-Block®, an angulator which relies on extra-oral landmarks, easy to identify. It positions the needle at the theoretical spot to realize an IANB anesthesia with a success rate close to 100 %.
Benefits for you:
- Reproductibility of injections: the needle is ideally positionned, whatever the morphology of your patient;
- Control of height, deepth and axis of the injection to enhance efficiency and security;
- Optimal protection: your fingers remain at distance from the injection point, which reduces the risk of accidental stings and blood exposure.
Benefits for your patients:
- Reduction of the injected dose: your patient receives a reduced quantity of anesthesic product;
- Reduction of injection stress: the length of the needle is hidden from your patient.
Avantages: security, patient’s comfort, time savings, simplicity
EZ-Block® is easy to use
Preparation of EZ-Block
DENTALGIC is a company created by Dr. Nicolas Caillieux, dental surgeon, who invented and patented the concept of EZ-Block®. Through his experience in Hospitals and Universities, he gathered anatomical inputs to create these new products.
EZ-Block® has been developed and patented between 2005 and 2014.

During my studies at the university, 3 years ago, I only practiced few times the IANB anaestesia, and without much success. Today, when I have to practice a deep treatment, or to work on a mandibular molar, I automatically do a loco-regional anaestesia, but moreover, I use the device imagined by Dentalgic. This tool requires some training at start, but it really helped me to demystify this anaesthesia. I continue to use it (with 35 mm needles) but I don't practice aspiration test.
The Quicksleeper tool was also tempting but many times but at such price... ouch ouch... For this reason, I will never thank enough Nicolas Caillieux.
Docteur David D.
I am happy to hear about you again, Docteur Caillieux, to tell you that I am very satisfied with your product, and that I use it nearly every day.
I will sadly not be n Köln [IDS 2019], but we will stay in contact in the future.
Docteur Enrico T.
I am satisfiee with the use of my device to guide syringes.
I don't use it every day, but pretty often.
Possibly you can think about an extension for biggger people!!!
Dr Catherine A.
I use "EZ-Block" for every spix, I am satisfied with the product, my success rate is higher.
I first inject some anesthedic product with an syringe in para-apical mode, and then I do a spix with the "EZ-Block" system.
Dr Olivier G.
Easy, comfortable, I use your product for all injections in the standard inferior alveolar nerve block.
Dr Jérôme B.
I reply to your letter.
I am very satisfied with your product. I don't use it very frequently because I don't do a lot of injections in the standard inferior alveolar nerve block, but I must admit the success rate is 100%.
I would need a short YouTube video to rememeber how to use it. Possibly I did not see it...

Good evening Dr CAILLIEUX,
I answer to your letter regarding my purchase of your guiding device.
I smiled when I received your letter, because I thought about calling you just after the purchase.
Indeed, I have been overwhelmed by the efficiency of this device, which enables me to deal with pulpites with serenity. The device is well engineered, easy to use, and very efficient.
I am really happy with it, and I use it systematically for all avulsions and canal obturation on the mandibular molars and premolars, as well as for multiple care.
This device deserves to be popular!
Thank you very much!
Dr Jean-Philippe B.
Dear Dr CAILLEUX
I thank you for your letter, and I will share with you my experience about your guiding device.
To make it short, this fantastic tool changed my professional life!
I must admit I was really not very good at Spix. Over 75% of miss rate after first injection! I tried again and again to take anatomy courses, to read again and again my practical bood about dental anesthesia, nothing could help! Whatever the method I used to get references, I constantly cought the mouth nerve, or the toungue nerve, or even (yes, believe me!) the face nerve, but never this f*** mandibular neve. Extracting a mandibular tooth was always a nightmare, with some attempts to use infitrations through ligaments, but it constantly ended up in dry alveolite.
And then I discovered your tool, whilst moving around the booths during the ADF trade show (in 2011 if I remember well).
When I was expalined how to use it, it was like seing the light at the end of the tunnel.
Back at my office, I did not wait, and I tested it on the fist mandibular spine of the day, and in less than one minute, half of the lower jaw of my patient was alseep. You can not imagine the relief of all fears related to mandible acts, the sense of liberation that gave me the use of super-gadget. It's a pity you have not won the Innovation Award in the ADF because this tool is truly life-changing, and greatly facilitates the practice. No need to ask ideological and metaphysical questions, take a Xanax before (!), to use a voodoo sorcerer (!!!), to twist the wrist to find the thing ligament, the concavity branch etc ... I can practice almost blindly thanks to this tool.
The few times I have failed are related to the fact that I have not positioned the ball at the earlobe. I advised my best friend and colleague who also encountered some difficulties in placing this anesthesia.
Sorry for all that spiel, but I wanted to share my personal story with infiltration in the mandibular nerve, so that you understand all the good things of the guidance system, which I systematically use when I have such anesthesia to practice.
And needless to say, I would recommend it to 100% of practitioners who have difficulties with mandible anesthesia, and who would ask questions about its reliability. It is extremely reliable.
From a practical point of view, there is an additional security, because the size of the guiding sheath requires the patient to keep the mouth open, and tongue naturally remains aloof.
Thank you so much for having developed this tool, I would say it gives to mandibular anesthesia the same advantages as WAMkey for loosening crowns.
