dental isolation Mouthpiece: Sizing and Placement
Placing the Mouthpiece
Prior to placing the Mouthpiece within the patient’s oral cavity, moisten the Mouthpiece and the patient’s lips.
Hold the sides of the Control Head with your index finger and thumb. With your other hand, fold the Cheek Shield onto the Tongue Retractor. Gently slide the folded mouthpiece into the buccal vestibule on the side to receive treatment. Angle the mouthpiece to allow the lower edge of the Tongue Retractor to move along the buccal edge of the teeth.
Move the bite block onto the occlusal surface of the teeth, just distal to the mandibular cuspid. Instruct the patient to “rest gently” on the bite block to secure.
Place the Cheek Shield into the buccal vestibule. Move the Isthmus onto the retromolar pad behind the maxillary tuberosity. Adjust the Tongue Retractor in the lingual vestibule as needed. Move the bite block distally to provide more vertical working room.
