An oral appliance as swallow training auxiliary device with open occlusal surface includes an open fixing frame and a palate pad. The open fixing frame is first made from cast by elastic material, or other elastic material done by 3D printed technology, and the palate pad uses an unsetting soft material to make a palate pad. After placement of the open fixing frame with the palate pad template on the upper dental arch of a patient, the patient does swallowing and uses tongue to press up on and cause the palate pad template to mold the shape of the palate pad to match tongue elevation position during swallowing and palate side in the oral cavity of the patient.

A compact, portable, self-contained dental trauma kit for on-site treatment and repair of dental avulsion, luxation and, subluxation in remote, non-dental and other emergent settings consists of a dental splinting material (the BAND-AID), dental resins (the glue), and a dental curing light (the glue hardener). This is everything necessary for the user to stabilize the traumatically involved teeth according to proper dental protocol in remote locations, without the need for any additional materials or other accessories. The use of the kit allows the patient to be treated rapidly, in less than thirty minutes, which drastically increases the survival rate of re-implanted or repositioned tooth or teeth.

A hemostatic paste comprising: a hemostatic component; and a light-curable component; wherein the hemostatic component comprises (2-hydroxypropyl)-Y-cyclodextrin.

The invention relates to a kit of parts for preparing a glass ionomer composition for dental use, the kit comprising a Paste A and a Paste B, Paste A comprising water, acid-reactive inorganic filler A, phyllo silicate(s), Paste B comprising water, poly-acid, non acid-reactive filler B, optionally chelating agent. The invention also relates to a hardenable composition obtainable by combining the pastes of the kit or parts and to the use of such a composition as or for preparing a dental cement, dental filling material, dental core build up material or dental root channel filling material.

Various methods and apparatus for processing audio signals are disclosed herein. The assembly may be attached, adhered, or otherwise embedded into or upon a removable oral appliance to form a hearing aid assembly. Such an oral appliance may be a custom-made device which can enhance and/or optimize received audio signals for vibrational conduction to the user. Received audio signals may be processed to cancel acoustic echo such that undesired sounds received by one or more intra-buccal and/or extra-buccal microphones are eliminated or mitigated. Additionally, a multiband actuation system may be used where two or more transducers each deliver sounds within certain frequencies. Also, the assembly may also utilize the sensation of directionality via the conducted vibrations to emulate directional perception of audio signals received by the user. Another feature may include the ability to vibrationally conduct ancillary audio signals to the user along with primary audio signals.

A method of treating a tooth of a user. Initially, a tooth is cut to have an opening of at least 1 to 4 mm in the direction along an occlusal surface of the tooth, or a tooth already cut to have such an opening is located. Following ensuring that the opening is dry, powdered selenite is inserted into the opening. Subsequently, the powdered selenite is covered with a dental composite, thereby sealing the powdered selenite in the tooth.

A retainer cooperating with a plurality of teeth and configured to stabilize the plurality of teeth, the retainer including at least one elongated arc which is shaped overall adapted to a natural curvature of a lower jaw or an upper jaw, wherein the at least one elongated arc is locally adapted individually to a surface contour of respective abutting teeth, wherein the retainer is machined from a sheet metal plate and includes two mutually parallel surfaces, wherein the sheet metal plate is made from a nickel titanium alloy, preferably a nitinol, wherein the retainer contacts a tooth surface in an installed condition of the retainer, wherein a machined surface of the retainer faces the tooth surface in the installed condition of the retainer, and wherein an upper side or a lower side of the retainer corresponds to an original surface plane of the sheet metal plate.

Cheek and lip expansion devices including an upper frame portion configured to extend about an upper dental arch, and a lower frame portion configured to extend about a lower dental arch. The upper and lower frame portions may each include first and second side members, each with anterior and posterior regions. An upper connecting member may extend between the anterior regions of the upper side members. A lower connecting member may extend between the anterior regions of the lower side members. The posterior regions of the upper and lower side members on respective sides of the frame are joined to one another to form a bendable radius that resists bending at a distinct point. The bendable radius on opposed sides permits the frame to be collapsed top to bottom. The frame may be collapsible side-to-side. A posterior crossbar may be provided extending between the posterior regions of the side members.

A dental veneer made from a composite comprising at least one organic binder, preferably with methacrylate, and inorganic solid particles as fillers. Methods for manufacturing the dental veneer include curing the composite with heat and light under pressure followed by laser treating the facial surface of the veneer to form a smoother facial surface. Filler particles at the facial surface of the veneer can be melted and/or coalesced together to form a continuous glass surface, which is more natural looking and better resembles natural tooth material as compared to ceramic veneers or other composited veneers lacking surface treatment.
