Extraoral Cheek Retractors
Cheek retractors should be cleaned with an enzymatic cleaner in an ultrasonic bath. An instrument washer can be used for the cleaning process provided the temperature does not exceed 135°C (275°F). Ensure retractors are thoroughly rinsed and fully dried prior to packaging for sterilization. Improper rinsing can leave a chemical residue from the cleaning agent and cause a reaction with the high heat from sterilization.
Cheek retractors can be heat sterilized in an autoclave sterilizer up to 135°C (275°F). After sterilization, cheek retractors are to remain in their sealed package and opened only at point of use.
