Question 1

What is a digital dental impression and how does it work?

Accepted Answer

A digital dental impression is created using an intraoral scanner that scans your teeth without contact. The 3D scanner glides along your teeth and captures a precise digital image of your dental structures within just a few minutes. Unlike traditional impressions, no putty impression material is used.

Question 2

Does the digital dental impression trigger a gag reflex?

Accepted Answer

No, digital dental impressions using an intraoral scanner typically do not trigger a gag reflex. Since no impression material is used and no impression tray needs to be held in the mouth, the procedure is significantly more comfortable. This digital method is particularly pleasant for patients with a sensitive gag reflex.

Question 3

How long does a digital dental impression take?

Accepted Answer

A digital dental impression is completed within just a few minutes. The scanning process itself usually takes only 2-3 minutes per jaw. Compared to traditional impressions, where the material must harden in the mouth for several minutes, the digital method is considerably faster.

Question 4

Is the digital dental impression more accurate than traditional impressions?

Accepted Answer

Yes, digital dental impressions deliver very precise results and capture even the finest dental structures accurately. The 3D scan data is available immediately and can be stored and shared without loss of quality. Traditional impressions, on the other hand, can be subject to errors during setting or transport.

Question 5

Are there any disadvantages to digital dental impressions?

Accepted Answer

Like any technology, digital dental impressions have limitations, such as in very deep areas below the gum line or with excessive salivation. In our Vienna practice, we use digital impressions where they can optimally demonstrate their strengths. For special situations, a traditional impression may still be advisable.
