Tooth surgery Anaesthesia without pain The Wand©

The Wand STA (STA stands for Single Tooth Anaesthesia) is a computer-controlled anaesthesia system that is increasingly replacing the classic anaesthetic injection in modern dentistry. The system was specially developed to minimise or completely eliminate the most common fear of dental patients - the pain of the anaesthetic injection.

With a conventional anaesthetic injection, the pain of the injection depends on two factors: the pain of the needle insertion and the pressure pain that occurs when the anaesthetic is pressed into the tissue too quickly. It is precisely the pressure pain - the unpleasant burning and pressing sensation - that many patients find painful and unpleasant, especially in the sensitive palate area.

The Wand STA solves this problem with two technical innovations: Firstly, it uses a wafer-thin, micro-fine needle that is significantly thinner than conventional dental needles. This significantly reduces the pain of the puncture. Secondly, the anaesthetic is not injected by hand, but is delivered by a computer-controlled microprocessor in a precisely controlled, constantly slow and even flow.

This constant low pressure is the decisive difference: the tissue can gently absorb the anaesthetic without being overstretched or irritated. The result: no or barely noticeable pain during the injection - even in particularly sensitive areas such as the palate or between the teeth.

Externally, the device looks like a small white pen (hence the name "The Wand"), which is pleasant and less threatening than a conventional syringe. This psychological aspect is particularly important for children and anxious patients who feel fear at the very sight of a syringe.

The question of what anaesthesia with The Wand STA feels like is one of the most important for patients who are new to the system and wonder whether the promises of painlessness really hold true. The answer is pleasantly surprising for most patients.

Before The Wand STA is inserted, the dentist usually applies a surface anaesthetic (an anaesthetic gel) to the mucous membrane that is to be pierced. This gel anaesthetises the uppermost layers of tissue and further reduces the pain of the needle insertion. Even the fine needles of The Wand are practically imperceptible.

The Wand system automatically controls the actual injection process - the introduction of the anaesthetic into the tissue - so slowly and evenly that the tissue does not react to pressure. Many patients report that they feel nothing at all during the entire injection or at most a minimal feeling of pressure that is not perceived as pain.

In particularly sensitive areas - especially the palate, which is often perceived as very painful with conventional injections - the difference to The Wand is particularly impressive. What used to be a burning, intense pain is reduced to a barely perceptible tingling sensation in most cases with The Wand.

Another pleasant aspect: because the anaesthetic is applied more precisely, the onset of anaesthesia is often quicker and more even than with conventional techniques. The feeling of waiting for the anaesthetic to take full effect is shorter.

The scientific literature confirms these patient experiences: Studies show that patients treated with The Wand rated the anaesthetic as significantly less painful than with conventional syringes - especially in anatomically difficult areas such as the hard palate.

The Wand STA is basically suitable for all patients who require local anaesthesia at the dentist - but there are certain groups for whom the system is particularly valuable.

Children are probably the most obvious target group. Children's fear of the anaesthetic injection is often greater than their fear of the actual treatment - and a painful first bite can shape their fear of the dentist for life. The Wand, with its pen-like, non-threatening appearance and low-pain injection, is ideal for giving children a positive first experience with local anaesthesia.

Anxious patients and people with dental phobia also benefit enormously: it is often the injection that triggers the worst panic reaction. Those who know that the anaesthetic is painless can engage much better with the treatment - and for some patients, The Wand enables them to attend regular visits to the dentist, which they would otherwise have avoided out of fear.

Patients who require anaesthesia in particularly sensitive areas - especially on the palate, between the teeth (intraligamentary anaesthesia) or in the frontal region - benefit from the precise and pressure-controlled delivery, which is much gentler in these regions than the conventional technique.

People with severe gag reflexes also often experience relief from The Wand, as the shorter, finer needle and faster onset of anaesthesia reduce treatment time and stress.

The Wand is also a gentle and precise alternative to conventional injections for older patients with sensitive tissue or altered anatomical conditions.

An important question for patients considering The Wand STA is: Does the anaesthetic work just as effectively as the classic injection - or do they have to compromise on pain relief during treatment?

The clear answer: Yes, The Wand STA is just as effective as conventional anaesthetic injections - in some clinical situations even more effective and precise. The Wand system uses the same proven local anaesthetics (e.g. articaine or lidocaine) as conventional injections. The difference lies solely in the method of administration - not in the medication itself.

A particular advantage of The Wand STA is intraligamentary anaesthesia (also known as periodontal ligament anaesthesia): This involves injecting the anaesthetic directly into the gap between the tooth and the bone, which enables very precise anaesthesia limited to a single tooth. This technique is almost impossible to control with a conventional syringe, as the high pressure can damage the tissue. The Wand, on the other hand, can fill this narrow gap with millimetre precision and controlled pressure - resulting in fast, effective anaesthesia of the individual tooth without numbing the lip or tongue.

The duration of anaesthesia is comparable to that of a conventional injection - depending on the anaesthetic used, the effect lasts for one to several hours.

Scientific comparative studies confirm this: When used correctly by an experienced dentist, The Wand STA achieves equivalent or better anaesthetic results than conventional methods - with the decisive advantage of a significantly more pleasant injection experience.

The question of how long the anaesthetic lasts after The Wand STA is of interest to many patients - especially those who find the numb feeling in the face after a visit to the dentist annoying and wonder whether The Wand offers an advantage here.

The duration of anaesthesia depends primarily on the local anaesthetic used - not the injection system itself. As The Wand STA uses the same medication as conventional injections, the anaesthetic duration is basically comparable: Articaine (the most common local anaesthetic in Switzerland) anaesthetises for one to three hours, depending on the dosage and region.

However, where The Wand STA can offer a real advantage is in intraligamentary anaesthesia (periodontal ligament anaesthesia): This technique specifically anaesthetises a single tooth without affecting the surrounding muscles, lip or tongue. This means that the lip, cheek and tongue feel completely normal after treatment - there is no numb face, no involuntary biting of the cheek and no restriction on speaking or drinking.

This precise, limited-tooth anaesthesia is a significant comfort benefit, especially for patients who need to return to work after a dental visit or for children who might otherwise accidentally bite their numb lip.

Your dentist will assess whether intraligamentary anaesthesia with The Wand is suitable for your treatment on an individual basis - not every procedure and not every tooth position allows this technique. In such cases, a classic conduction anaesthetic is used, with the numb feeling lasting a few hours as usual.

The question of the cost of The Wand STA and whether the surcharge is worth it compared to normal anaesthesia is relevant for many patients - especially in Switzerland, where dental costs are high anyway and every additional item in the cost estimate is critically scrutinised.

At CITYDENTAL, local anaesthesia with the Wand system costs CHF 35 more than the conventional injection. At first glance, this amount appears to be a small but noticeable additional charge - but it is quickly put into perspective when you consider the added value.

For patients with a fear of injections, a strong gag reflex or a low pain threshold, a pleasant, stress-free anaesthetic can make all the difference - between a treatment that can be endured relatively calmly and a highly stressful experience that increases dental anxiety.

For parents taking their child to be anaesthetised for the first time, the investment of CHF 35 can prevent much more expensive consequences in the long term: A child traumatised by a painful initial anaesthetic may avoid the dentist for years - with consequential costs from untreated tooth decay and other conditions.

Another financial aspect: The Wand can reduce the need for anaesthetics in certain situations - for example through more precise intraligamentary anaesthesia - and shorten the treatment time, which indirectly contributes to better cost efficiency of the overall treatment.

The question of whether CHF 35 extra costs are worthwhile can therefore be answered with a clear yes for most patients - especially when you consider that a pleasant treatment experience increases the willingness to visit the dentist regularly and without delay.

The question of whether The Wand STA is covered by health insurance in Switzerland is understandable - and the answer unfortunately corresponds to the general picture of Swiss dental insurance.

Compulsory basic insurance (KVG) does not generally cover dental treatment - and this also applies to additional services such as The Wand STA. As the Wand system is a comfort service that goes beyond medically necessary anaesthesia, basic insurance does not generally cover the costs.

Interestingly, however, there is one exception that is rarely known in practice: if The Wand STA is used in patients for whom conventional anaesthesia is not possible or risky for medical reasons - for example, in the case of a proven allergy to certain preservatives in standard anaesthetics or in patients with certain neurological diseases - coverage by basic insurance can be argued in individual cases. However, this must be applied for individually and in writing to the health insurance company.

Depending on the policy,supplementary dental insurance can pay contributions towards dental treatment - some tariffs also include or at least partially cover additional services such as The Wand. It is worth checking your own supplementary insurance.

However, given the low surcharge of CHF 35, for most patients The Wand STA is an affordable personal benefit that does not require insurance cover to be worthwhile. For most patients, the added value in terms of comfort, stress reduction and a pleasant treatment experience clearly outweighs the modest financial outlay - and is therefore one of the most favourable quality improvements you can choose when visiting a dentist.
