Impression materials: why they still deserve a place in your product selection
Featured Products Promotional FeaturesPosted by: Dental Design 2nd December 2021
It goes without saying that intraoral scanners have, in many ways, helped to revolutionise the impression-taking process. But as professionals will be aware, every case provides unique challenges. This means that a fully digital approach may not always be the best option and traditional impression materials are still a viable option in a range of clinical scenarios.
But what are some of the clinical situations where traditional impression materials are better suited to the task at hand?
Dr Kunal Shah, principal dentist at Leo Dental explains certain situations where he uses traditional impression materials and why this is the case:
‘I do a lot of dental implant work in my practice and for many cases I use traditional impressions as they definitely offer an advantage. Although digital scanners are very impressive, they can struggle to capture accurate subgingival detail. I find that physical impressions are a better choice for these cases as they flow into the areas that a scanner can’t reach – this helps ensure that these all-important details are as accurate as possible, giving everyone involved in the treatment process the best information possible.
‘Another type of case where I find physical impressions to be the better choice is when taking impressions for retainers or night guards. I mostly use them for retainer work, and this is simply because they are a more affordable option and can still achieve exceptional detail capture. For retainer work, dental laboratories often incorporate the cost of the impression into the price, meaning that if you use a digital scanner this can effectively double what you would pay for the same outcome as there is a surcharge for them to print models. This may not seem like a huge outgoing, but it can quickly add up!
‘Ultimately, there are a number of benefits to physical impression materials that mean they should definitely remain in a modern dentist’s armamentarium. Digital scanners aren’t always as time-saving as people believe, and often you can achieve a similarly accurate result in less time with an impression material. For subgingival detail impression materials are also invaluable – until digital technology can reliably capture this it means that for such cases, physical impressions can’t be beaten.’
