    摘要: A dental impression tray is made of thermoplastic material which may be heated in order to shape the tray to accommodate the patient's dental arch. The tray includes a channel for receiving impression material, and the channel has a folded section which may be unfolded when the tray is heated in order to increase the height, width or length of the channel. The folded section extends outwardly from the channel and provides convenient gripping structure for removing the tray from the mouth after the impression is taken.

    摘要: A dental impression tray has an outwardly extending flange that is connected to posterior portions of a trough or channel for receiving a quantity of impression materials. The flange permits the tray to be firmly gripped on the sides of the channel in areas adjacent opposite posterior regions of the patient's dental arch, so that the cured impression material may be disengaged from the arch without excessive permanent distortion of the impression. Preferably, the flange extends along the entire perimeter of the channel and adjacent an occlusal portion of the channel.

    摘要: Presently described are curable dental compositions comprising a polymerizable ionic liquid. The polymerizable ionic liquid comprises one or more ethylenically unsaturated (e.g. free-radically polymerizable) groups. Various embodiments of curable dental compositions are described. In some embodiments, the polymerizable ionic liquid is a monofunctional polymerizable ionic liquid comprising an ethylenically unsaturated group. In other embodiments, the polymerizable ionic liquid is a multifunctional polymerizable ionic liquid comprising at least two ethylenically unsaturated groups. The curable dental compositions describe herein can be utilized as dental primers, dental adhesives, dental sealants, and dental composites. In many embodiments, the curable dental compositions further comprise an initiator such as a photoinitiator.
