Patent number: 11589970Abstract: A dental mouthpiece is provided that may be attached to a high-suction dental adapter for the purpose of assisting the dental staff during dental procedures through chair-side, hands-free suction, and isolation. Such mouthpiece may include a main body portion, a cheek retractor portion, and a suction connector portion. In some embodiments, the main body portion, cheek retractor portion, and suction connector portion (and sub-portions thereof) may be molded in one piece, preferably by injection molding. In an exemplary embodiment, the mouthpiece may be made of a material that is flexible, translucent, conducive to injection molding, high heat-resistant, and autoclavable. Such a material may include silicone. Because the mouthpiece may be made of high heat-resistant and autoclavable material, such a mouthpiece may be reusable.Type: GrantFiled: March 27, 2014Date of Patent: February 28, 2023Assignee: SOLMETEX, LLCInventors: Thien Nguyen, Tam Thanh Pham
