US Patent 12290418 (US12290418B2)

• Title: Intraoral device
• Assignee: Solmetex LLC
• Inventors: Thien Nguyen, Tam Thanh Pham
• Filing Date: 2024-09-04
• Issue Date: 2025-05-06
• Abstract: 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 a 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 a high heat-resistant and autoclavable material, such a mouthpiece may be reusable.

Plain-Language Overview of Independent Claims:

• Independent Claim 1: This claim describes an isolation mouthpiece for dental procedures. It features a main body with two walls (first and second) that are spaced apart and connected by a third wall, forming an enclosed pocket. The second wall has perforations along its edges and an internal wave-like structure with crests that contact the first wall to keep the walls separated during suction, and troughs that form gaps for fluid suction. The main body tapers from a wider first end to a narrower second end. Extending from the first end is a suction connector portion with a tubular conduit for vacuum attachment, including a cutout for interlocking with a suction system. The suction connector also features a mouth prop with inwardly tapered sides and ridges. A cheek retractor portion, with rounded edges, is coupled to the narrower second end of the main body.
• Independent Claim 11: This claim is similar to Claim 1, describing an isolation mouthpiece with a main body, suction connector, and cheek retractor. Key features include the main body's first and second walls with perforations and an internal wave-like structure (crests for contact with the first wall, troughs for fluid suction), and a tapering shape. The suction connector has a tubular conduit for vacuum, and a mouth prop with inwardly tapered, ridged sides. The cheek retractor has rounded ends, and critically, the first and second walls of the main body that transition into the cheek retractor portion remain spaced apart for a distance before connecting within the cheek retractor portion.
• Independent Claim 20: This claim describes a mouthpiece with a main body that has a wider first end and a narrower second end. The main body comprises a first wall and a second wall, which together define an interior space. The second wall has internal crests that contact the first wall to create contact points and troughs that form gaps for fluid passage, and these contact points are not attached to the first wall. A third wall connects the edges of the first and second walls. A cheek retractor portion extends from the narrower second end and is connected to both the first and second walls of the main body.
