Abstract:
An intra-oral simultaneous bilateral inter arch isolation appliance features a generally W-shaped body having first and second cheek retractor wings, and first and second transitions respectively joining the cheek retractor wings to a tongue crib of generally U-shaped configuration with an open posterior end. In a patient worn position, each cheek retractor wing runs buccally along a respective half of a patient's dental arches to retract and isolate buccal mucosa, while the transitions curve posteriorly around the rear molars between the maxillary tuberosity and retromolar pad to carry the tongue crib inside the dental arches, where it shields and isolates the tongue. Commissure cradles at anterior ends of the cheek retractor wings hook around the patient's oral commissures at terminal ends of the appliance. Inner passageways within the body accommodate fluid extraction and/or light transmission through the appliance.

Claim (Index 1):
An intra-oral simultaneous bilateral inter arch isolation appliance comprising:\n a body having, in superior plan view, a generally W-shaped configuration bisected by a medial plane, said body having a singular, unitary seamlessly integral construction defining:\n a tongue crib of generally U-shaped configuration in superior plan view and bisected by said medial plane, said U-shaped configuration being closed at an anterior end thereof and open at a posterior end thereof to receive a patient's tongue through the open posterior end and shield said tongue behind the closed anterior end thereof; \n a first cheek retractor wing spaced laterally of the medial plane to a first side thereof and reaching anteriorly-posteriorly therealong; \n a second cheek retractor wing spaced laterally of the medial plane to an opposing second side thereof and reaching anteriorly-posteriorly therealong; and \n first and second transitions respectively joining the first and second cheek retractor wings to respective halves of the tongue-crib on the opposing sides of the medial plane at the open posterior end of the tongue crib such that the tongue crib projects anteriorly from the transitions within a space bound between the cheek retractor wings; \n whereby in a patient worn position of said appliance, each cheek retractor wing runs buccally along a respective left or right half of a patient's mandibular and maxillary dental arches to retract and isolate buccal mucosa from said dental arches, the transitions curve posteriorly around molars of the dental arches between the patient's maxillary tuberosity and retromolar pad, and the tongue crib accommodates and shields the patient's tongue between said halves of the dental arches, thereby isolating the tongue from said dental arches.
