Claim 7

The mouth prop of claim 1 wherein: said cheek deflectors are formed from a flexible material which bends away from said upper and lower U-shaped sections upon inward bending of said connecting sections during closing of the patient'mouth.

Claim 8

Claim 11

A dental mouth prop comprising: a. a support constructed from a flexible tubular member having an upper U-shaped section with first and second ends, a lower U-shaped section with first and second ends, a first curved connecting section joining the first end of said upper U-shaped section to the first end of said lower U-shaped section, a second curved connecting section joining the second end of upper U-shaped section to the second end of said lower U-shaped section; b. first and second cheek deflectors respectively secured to different sides of said upper and lower U-shaped sections, said cheek deflectors being curved generally to a contour approximating the cheek surface of the mouth, said cheek deflectors holding the patient's cheeks away from the dental arches when said mouth prop is inserted into the patient's mouth; c. a tongue deflector secured to said support at the front of said lower U-shaped section, said tongue deflector holding the patients's tongue in the lower portion of the patient's mouth when said mouth prop is inserted into the patient's mouth; d. upper and lower lip deflectors respectively secured to the front of said upper and lower U-shaped sections of said support, said lip deflectors engaging the upper and lower lips of the patient's mouth when said mouth prop is inserted into the patient's mouth; e. said tubular member having a plurality of orifices which drain saliva from the patient's mouth when said mouth prop is inserted into the patient's mouth; and f. a section of tubing coupled to said tubular member for draining the saliva within said tubular member.

Claim 12

The mouth prop of claim 9 wherein: a. said cheek deflectors are formed from a flexible material which bends away from said upper and lower U-shaped sections upon inward bending of said connecting sections during closing of the patient's mouth; b. a plurality of apertures are disposed along the sides of said upper and lower U-shaped sections; c. a plurality of fasteners are attached to said cheek deflectors for removably securing said cheek deflectors to the sides of said U-shaped sections by insertion of said fasteners into said apertures, said cheek deflectors being removably securable to said upper and lower U-shaped sections in more than one position disposed along the sides of said U-shaped sections; d. said upper and lower lip deflectors are removably secured to apertures in the front of said U-shaped sections by fasteners; and e. said tongue deflector is removably secured to an aperture in said lower U-shaped section by a fastener.
