The Wand

It doesn't look like a syringe. It doesn't feel like a syringe. And it works better than a syringe, resulting in a more pleasant experience. Milestone Scientifics' computer controlled local anaesthetic delivery systems, which feature the Wand, a lightweight handpiece that looks like a pen, eliminates the pain you can feel from an injection.

The CompuDent™ system features state-of-the-art technology that makes painful injections a thing of the past. This revolutionary system, consisting of two main elements, the CompuDent™ computer and the Wand handpiece, features a pain-free approach to delivering local anaesthetic.

The traditional dental syringe has changed very little since its introduction in 1853. It is a difficult-to-handle item and its use frequently causes unnecessary pain due to the amount of pressure needed to inject anaesthetic. In the era of modern dentistry it would seem fitting to use computers to deliver painless dental anaesthesia.

It has been our experience that patients are amazed to feel no pain, even in those areas of the mouth which might have been expected to be sensitive.

It has been remarkable in demonstrating that the injection is still what causes most phobia and when this is painless, the rest of the treatment proceeds in a very relaxed fashion. The wand is being constantly evaluated and monitored in various clinical trials, one of which is at the "Q Clinic" in London.

The Method

Topical anaesthetic is first applied to freeze the gum and then a tiny needle is gently introduced through the already-numb tissue to anaesthetise the surrounding area. The controlled flow also eliminates the "bee sting" effect, which is descriptive of the pain associated with a surge of fluids into tissue

What our PATIENTS say

Technical Details

With the microprocessor-controlled CompuDent™ delivery system and the revolutionary Wand® handpiece, giving local anesthetic injections of all types has never been easier. Because less penetration force is required, needle advancement is almost effortless. The flow rate of the anesthetic is controlled by a microprocessor instead of the pressure of the clinicians' thumb, making it more precise. The Wand can make giving a painless injection one of the easiest tasks in the day.

Think of the palm-thumb grasp and pressing movement required to inject with a traditional syringe. Then picture the precise movements you can make when holding a pen - to write, to draw. No wonder the Wand enables such accuracy. The pen-like grasp allows bi-directional rotation during injection, which prevents needle deflection that can occur with a traditional syringe. A straighter path results in a more accurate injection, meaning fewer missed blocks, and a more rapid onset of anesthesia.

Injection Dynamics

There are three basic stages of a dental injection and, therefore, three opportunities for a patient to feel discomfort: the initial needle Puncture, the Penetration of the needle to the injection site, and the Delivery of the anesthetic solution. The CompuDent™'s controlled flow and pressure technology and related techniques will allow you to give an easier, consistently more comfortable injection, even in the dense tissue of the palate.

A Pre-Puncture technique has been developed for the initial tissue Puncture; an Anesthetic Pathway is used to Penetrate the needle through the tissue; and the Delivery of the anesthetic is below the patient's Pain Threshold. The design of the Wand® handpiece also allows easy rotation, reducing the force necessary to penetrate tissue and canceling needle deflection.
