Question: 1 / 400

Which procedure requires the patient chair to be placed upright?

Maxillary impressions

When performing maxillary impressions, it is essential for the patient chair to be placed upright to ensure an accurate impression and the patient's comfort. An upright position allows for better visualization of the maxillary arch and helps the dental professional properly align the impression tray with the patient's mouth. This position also aids in minimizing the risk of gagging and discomfort that a patient may experience when the chair is reclined.

In contrast, certain procedures like mandibular impressions can be taken when the chair is slightly reclined, and procedures such as root canal treatment or extractions often require the chair to be positioned in a way that provides optimal access and visibility for the clinician, which may differ from the upright position. Each dental procedure has specific requirements regarding patient positioning to ensure both efficacy and patient comfort.
