It serves as a disposable hygienic barrier, preventing direct contact between the bite block and the patient's oral cavity. The use of the hygienic protective bite cover is recommended but not mandatory to reduce the risk of cross-contamination, as the bite block is positioned intraorally. The bite block may be used with or without hygienic protective bite cover, as it is designed to be reusable and can be reprocessed in accordance with validated cleaning, sterilization and disinfection procedures (as described in the instruction for use). 2 {6} DÜRR DENTAL ### 8.
