Injex: Needleless local Anaesthesia
The use of Injex for dental procedures has been gaining popularity in recent years, giving dental practitioners the ability to administer local anaesthesia and other medication without using needles.
How does it work?
Injex works by using a short burst of high pressure to deliver the medication uniformly in a spray-like manner, rather than inserting a needle into the gums.
Why is it better for patients?
The strongest motivating factor for patients is the painlessness of this process – it takes a fraction of a second with virtually no discomfort. In addition to making dental procedures relatively painless, using such technologies for local anaesthesia has several other benefits as well. Drugs administered through Injex have a much shorter uptake time, with rapid diffusion of the medication in the region. This means that the chemicals reach effective concentration levels much quicker, and effects of the anaesthesia are noticeable immediately. With this technology, lower doses need to be delivered to observe a similar level of effect, and the risk of side effects of any medication is substantially reduced. While all of these are hugely beneficial for people of any age, Injex is great for children in particular, who not only have a greater fear of dentists and needles but also lower dosage limits for medication.
Is it safe?
Firstly, needleless injectors are safer and more hygienic as compared to traditional anaesthetic delivery systems. This is especially helpful if patients are worried about needles being reused and spreading infections. Using Injex also completely eliminates any risk of intramuscular injections. What this means is that the pain and discomfort felt in the region after the anaesthesia wears off is extremely minimal.
How does it work?
The Wand is essentially a computerised anaesthetic delivery system, offering control over the pressure, volume and precise rate of flow of the medication being delivered.
Why is it better for patients?
The most common misconception among patients is that the pain felt during injections is caused by the needle pricking the skin. However, it’s actually the uneven delivery of the medication into the tissues that causes most discomfort. Because it’s entirely computerised, the Wand eliminates this by delivering the medication appropriately at a constant pressure to automatically compensate for differences in tissue densities.
Is it safe?
Administering injections with a computerised delivery system like the Wand is highly popular because of the precise control and reliable injections it offers dental practitioners, even in difficult areas. Using the Wand also removes any “human error” with safety features such as a self-retracting needle, so even the most anxious patients can rest easy.
Painless and practical
