Changing a material you have used for ten years: the risk is not the product, it is the quantity

Almost every practice has at least one product it keeps using without being convinced by it. Not out of blind habit, but because of a calculation made at some point and never made again.

The calculation is simple: changing carries a risk, staying put does not. And as long as the current product performs acceptably, the risk is not worth it.

What is interesting is where that risk comes from, because it is usually not clinical.

The real risk is quantity. If trying a material means buying six months' worth, and two weeks in you discover you do not like how it handles, you have a problem in the cupboard that will look at you every day.

It is not the failure of the trial that puts people off, it is its duration. A fifty-euro mistake is forgotten; an eight-hundred-euro mistake stays on the shelf.

This produces an effect worth recognising: you are not choosing the best product, you are choosing the one you already chose. And the original decision may date back to a rep who has not called in for years.

Meanwhile the market has moved. New materials have appeared, prices have shifted, and suppliers that did not exist back then are around today.

The condition that makes reopening the choice possible is being able to buy small. One pack, not a case.

This is what makes a catalogue where each seller sets their own terms worth using: the minimum quantity is not a single platform-wide rule, and in many cases you can take a single pack to see how it handles.

The right way to run the trial, though, is not simply to buy. It is to use the product on enough cases, in exactly the same steps where you use your usual one, and note what genuinely changes chairside.

Many trials fail for a banal reason: the product is tried once, on a bad day, and written off. A new material needs a few appointments purely to get used to the feel of it.

If after those appointments the product is equivalent and costs less, you have found a recurring saving. If it is better, you have improved a procedure. If it is worse, you have spent the price of one pack to find out.

In summary: the brake on change is quantitative rather than clinical, a mistake that stays in the cupboard weighs more than it costs, standing still means working from a choice made years ago in a different market, being able to buy a single pack reopens the assessment, and a trial needs several appointments to get past the habit effect.
