Abstract: An intraoral device (1) with a pair of dental aligners (10), each aligner having an outer shell (100) of rigid plastic in the shape of a rounded V defining branches joined at the front part (10a) of the outer shell. The front part has a truncated part in the form of an elongate notch (104), which confers flexibility on the outer shell in a plane orthogonal to the median sagittal plane of the aligners by bringing together or spacing apart the branches of the V. The outer shell includes an impression (106) formed in the front part on the outer face of the outer shell and extending on either side of the elongate notch. The notch cooperates with an attached wedge (50) which serves as a mechanical abutment for blocking flexion of the outer shell at a given curvature when the attached wedge (50) is fixed in the impression (106).

Abstract: A stable affixation system for dental implantation includes a fixation tray having, for rapid placement, a housing defining a chamber whose inner surface is configured to house a flowable or malleable material and be placed over one or more teeth during guided dental implantation surgery. A central portion not configured to flex is situated between housing side walls. Each such side wall has an upper side portion and a lower side portion.

The lock reduces or eliminates freedom of movement of the tray. The system allows rapid removal and is sturdy enough to withstand forces including from various angles and leverage. The central portion may hold registration elements.

Abstract: A stable affixation system for dental implantation includes a fixation tray having, for rapid placement, a housing defining a chamber whose inner surface is configured to house a flowable or malleable material and be placed over one or more teeth during guided dental implantation surgery. Housing side walls are joined to a cross member that has a flexion region on each side of the housing, each side wall having an upper side portion and a lower side portion.

Abstract: A dental device has a U-shaped carrier with at least one channel for embracing an arch of teeth. There are recessed insets in the channel. Discrete inserts carrying a beneficial agent can fit into the insets and release the agent gradually. The device may be used in a therapeutic application and as an athletic mouthguard.

Abstract: In an exemplary embodiment, a method of creating an impression of structures of the human oral cavity comprises: preparing impression trays: creating a first, or base, impression; grinding out portions of the base impression; and using the void(s) in the ground out base impression to take a second, or wash, impression.
