Bonding Agents Cost More Than Rocket Fuel

If you ever needed proof that dentistry operates in a different universe, here it is. Per millilitre, the adhesive you place before a simple composite filling can cost more than rocket fuel. It can even rival high grade printer ink, which already has a reputation for being absurdly expensive.

That probably will not surprise most UK dentists. Bonding agents are one of the most precious fluids in the surgery, yet the way they are dispensed is often the least controlled. A few extra drops here, a bit of waste on the pad there, a slightly heavy handed squeeze, a different technique between team members. Before you know it, a product that is already expensive quietly becomes one of the biggest hidden consumable drains in the practice.

This is exactly why systems like Ivoclar’s Adhese Universal VivaPen often create such a conversation. The adhesive science is solid, but the real shift comes from how the material is delivered. Before we get into workflows and team consistency, let’s look at the maths.

Because the economics matter as much as the chemistry.

Understanding the Real Cost per Application

To talk about value, we first need to talk about numbers in a way that makes sense at practice level. Here is how the cost per application is calculated for both a traditional bottle system and the VivaPen.

Bottle Bond

A standard bottle contains 5 ml at £105. Most clinicians use roughly 0.05 to 0.12 ml per application depending on how they dispense. We have used a realistic mid point based on survey data and clinical usage patterns.

That produces an average cost of about 85 pence per application. This is already more expensive than many realise but it becomes even higher when there is:

• Spillage 

• Over dispensing 

• Evaporation 

• Saturated microbrushes 

• Team variability between clinicians

In other words, 85 pence is often a best case scenario.

VivaPen

The VivaPen is 2 ml at £68. Ivoclar guarantees 120 metered applications per pen

because each click dispenses a fixed volume. The cost becomes very easy to calculate.

£68 divided by 120 equals about 30 pence per application. No over dispensing. No wasted drops. No evaporation on a mixing well.

Already we have a meaningful difference. Now let’s expand this across an average UK practice.

The Average UK Clinic and Its Adhesive Workload

An average sized UK mixed or private practice usually delivers 1,000 to 1,400 direct adhesive restorations per year across the clinical team. It varies by practice, but this is a sensible working range.

To keep the maths clear we will use 1,200 adhesive restorations per year for comparison.

Annual Spend Comparison

Using 1,200 applications:

Bottle system: 1,200 applications at 85 pence equals £1,020 per year.

VivaPen: 1,200 applications at 30 pence equals £360 per year.

Annual difference: 

About £660 saved simply through metered dispensing.

That does not include the soft costs such as repeat applications, discarded microbrushes, contaminated wells, evaporation or inconsistent placement.

Once those are included, the financial gap widens even further.

Why These Numbers Matter More Than Ever

Bonding agents are one of the most expensive fluids used in healthcare. On a per millilitre basis they can cost:

• More than rocket fuel, which sits around £4 to £6 per litre at industrial scale 

• More than printer ink, which is often cited at £2,500 per litre

When a product is this concentrated in value, small inefficiencies become big drains. It is not that the adhesive is expensive for the sake of it. It is that precision chemistry comes at a price, so your delivery system must respect that value.

This is where the VivaPen changes the conversation from chemistry to workflow.

The Value of Metered Dispensing for the Whole Team

One of the biggest hidden challenges in a practice is that bonding steps vary between clinicians and between nurses. Some dispense tiny amounts. Others dispense generously. Some reuse bonding wells multiple times. Others discard after one use. Some follow the manufacturer’s protocol to the letter. Some adapt it in small ways.

These variations feel subtle but they compound over thousands of restorations.

The VivaPen removes most of that variability. Every click is the same amount. Every application is fresh. No wells to mix. No risk of air exposure. No “I think that is enough”. It becomes almost impossible to waste adhesive unless you try very hard.

That consistency supports:

• More predictable clinical outcomes 

• A cleaner, faster bonding workflow 

• More confidence among associates 

• Less training burden for nurses 

• Less variance in consumable usage across the team 

• A smoother experience for patients who get the same protocol regardless of provider

When you reduce variability, you do not just improve efficiency. You improve quality and predictability. That is a universal business benefit.

The ROI Conversation

At first glance, the VivaPen appears more expensive per millilitre because the pen is £68 for 2 ml. Many dentists look at that small figure and assume it is costly. The opposite is true when you look at what we actually pay for a reliable application rather than for the bottle.

Using the corrected figures:

Annual saving: About £660 per year for an average UK clinic.

Five year saving: Around £3,300.

This estimate is conservative and does not include:

• Reduced microbrush waste 

• Reduced assistant time preparing and clearing bonding wells 

• Fewer adhesive related failures due to evaporation 

• Reduced inventory loss 

• Reduced intra team variation

When all factors are considered, the economic advantage becomes even clearer.

So What Can Be Done?

For a material that costs more per drop than rocket fuel and printer ink, the smartest thing we can do is control how it is dispensed. That is the entire logic behind moving from an open bottle to a closed, metered system.

The VivaPen does not just cut costs. It changes the culture of adhesive dentistry within the practice. It makes the adhesive step more predictable, less wasteful and more aligned with how high value materials should be handled.

Most importantly, it removes the guesswork that creates clinical inconsistency. When everyone is using the same click based system, your restorative dentistry becomes more uniform, more efficient and less prone to simple but expensive errors.

Conclusion

Bonding agents will remain one of the most concentrated value items in the surgery. They are powerful, precise and essential to modern adhesive dentistry. The real question is not whether they are expensive. It is whether we are using them in a way that respects their value.

When a single step in the procedure can cost more per millilitre than the fuel that launches rockets into space, it makes sense to use a system that eliminates waste and removes variability between team members.

The VivaPen is not a luxury. It is a control mechanism. It protects margins, improves workflow and brings consistency to the bonding step for the entire clinical team. And when viewed across a full year of adhesive dentistry, the financial and operational difference becomes substantial.
