Digital dental impressions: how scanning works and how it differs from a conventional impression

Welcome to the era of dental impressions without trays and paste! Modern technology is changing the patient experience at the dentist, reducing the familiar discomfort of conventional impressions and providing highly precise results.

The 3Shape intraoral scanner allows a detailed digital impression to be created quickly, without unpleasant tastes or gagging, making your visit more comfortable and efficient. This technology is suitable for a range of dental treatments, from prosthodontics and implants to braces and cosmetic dentistry procedures.

How 3Shape digital scanning works

The 3Shape intraoral scanner is a high-precision device that captures 3D images of the teeth and gums without the need for conventional impression material.

The main benefits include:

No trays or paste – it avoids the unpleasant sensations associated with traditional impressions.

Speed – scanning each dental arch takes only a few minutes.

High precision – detailed 3D images allow crowns or veneers to be made with a precise fit.

Patient comfort – it reduces the discomfort, nausea or stress associated with conventional impressions.

This modern method is suitable for patients of all ages, including those who have had unpleasant experiences with traditional impressions.

Treatments that benefit from digital scanning

3Shape digital scanning is used in several types of treatment:

Prosthodontics – crowns and bridges made quickly and with a precise fit.

Dental implants – accurate planning and a precise fit for implant-supported restorations.

Braces – a digital model for planning orthodontic treatment with aligners or fixed braces.

Cosmetic dentistry – designing veneers and cosmetic restorations, or simulating your smile.

The advantages of digital scanning over conventional impressions

Less time in the dental chair – taking the impression is much quicker.

Results visible straight away – the dentist can check on the spot that the scan is correct.

Better communication with the laboratory – the digital files are sent to the technician instantly, avoiding the risk of impressions becoming distorted.

Greater comfort – patients avoid unpleasant tastes and feelings of nausea.

Accurate records – 3D scans can be kept to monitor how treatment progresses.

The patient experience

Many patients describe the experience of a digital impression as:

  • “Much more comfortable than a traditional impression”
  • “Quick and comfortable”
  • “Interesting to see the 3D model of my teeth on screen”

Even sensitive patients, or those with a strong gag reflex who used to avoid impressions, can now have complex treatment with less stress.

How to prepare for digital scanning

Brush your teeth before your visit to remove any food debris.

Tell your dentist if you have removable dentures or temporary restorations.

Relaxing and breathing calmly helps make the scan quicker and more accurate.
