US Patent 10314672 Cheek and tongue retractor

The retractor is a generally U-shaped device for protecting the cheek and tongue from instruments used during dental and prosthodontic procedures. The retractor has a planar base defined by two spaced arms, a pair of upright shields extending from the arms, and a posterior connector connecting the shields. The base is contoured to grip the tooth adjacent to the tooth to be treated, and thereby, secure the retractor within the patient's mouth.
