What does “Taking a dental impression” mean?
Taking a dental impression records the shape of the teeth and surrounding gum. Impression material in a tray or an intraoral scanner can provide the record used for diagnosis and for making restorations or appliances.
Original spelling: 본뜨기
Material or a surface scan can provide the record
In the traditional method, a tray containing impression material is placed over the teeth and removed once the material sets. Digital methods scan the surfaces inside the mouth from several directions to produce a three-dimensional record. Both aim to capture the shape of the required area.
Tooth shape and the bite may both be needed
Making a restoration or appliance can require not just the shapes of the upper and lower arches, but also how the upper and lower teeth meet. A bite record may therefore be taken in addition to the upper and lower shapes. Records for diagnosis and those for final manufacture also have different purposes.
Tell the team beforehand if you gag easily
The tray and impression material can feel bulky or trigger a gag reflex. Describing previous difficulties or gagging beforehand allows you to discuss ways to reduce discomfort. A digital scan, which does not put impression material in the mouth, may help; its suitability for the treatment should be checked. Manufacture and a try-in may follow after recording.
Frequently Asked Questions
Does an impression show decay inside a tooth?
An impression mainly records the surfaces of teeth and gums. Its purpose differs from X-rays used to assess the inside of teeth, roots or bone.
Does a digital scan complete all the records needed?
The necessary records depend on the treatment and may include both arches and the bite. Having a scan does not by itself establish that every record required for the final restoration is complete.
