Question: 1 / 400

What is the primary function of Minnesota retractors?

To hold instruments

To retract cheeks

The primary function of Minnesota retractors is to retract cheeks, which facilitates improved access and visibility during dental procedures. These retractors are specifically designed with a curved shape that helps to hold back the soft tissues of the cheeks and lips, allowing the dental professional to work more effectively without obstruction from the patient’s oral cavity. The design of Minnesota retractors enhances the comfort of the patient by minimizing the need for manual retraction, which can cause fatigue or discomfort during longer procedures.

While other instruments may serve different functions—such as stabilizing a patient or isolating teeth—Minnesota retractors are distinctively utilized for their ability to create space in the mouth, ensuring that the dental team can perform their tasks with both precision and safety.
