The body includes a proximal end and a distal end having a dispensing orifice. The wall comprises a polymeric material, and a time-temperature indicating material and/or a temperature indicating material. The capsule includes one or more composite resins positioned in the interior space of the body.

The invention provides a dentition movement track indicator and a tracing method. The device includes an intra-oral fixation assembly and an extra-oral movement indicating assembly, wherein the intra-oral fixation assembly includes a lower denture base, a left side retention steel wire, a right side retention steel wire and a positioning steel wire. The lower denture base is arranged on the lingual side of the lower dentition and respectively extends from a lower incisor to the far center of the last tooth on the left side and the right side and clings to the lingual mucous membrane. The left side retention steel wire and the right side retention steel wire are distributed in a left-right symmetry mode. The extra-oral movement indicating assembly includes a connecting rod, an arc rod, an indicating plate and a plurality of rectangular parallelepiped thin rods. According to the dentition movement track indicator, an intra-oral fixation assembly.

An endodontic file, for manual or motor driven use by an endodontist, includes a color-coded handle, a shank, and a serrated cutting edge. The cutting edge of the endodontic file is side-cutting with pyramidal teeth and ends in a pointed tip. The endodontic file is used manually inside the root canal in an up and down axially aligned motion and these pyramidal teeth will provide a ripping action. A second type of endodontic file has a curved cross section and a sharpened tip. with pyramidal teeth lining the edges of curved blade section. A third type of endodontic file has a flat debriding side which tapers to a point; with a series of adjacent 3-D pyramids emerging from this surface for removing loose material or in urging already loosened material from a root canal.

The present disclosure relates to ornamental indicia carrier and method of producing the same. In some embodiments, the ornamental indicia carrier comprises an ultraviolet light (UV) cured ink printed on a thin flexible film and combined with an adhesive layer. The ornamental indicia carrier is capable of enduring the conditions inside the mouth for an extended period of time and can be used in conjunction with a dental appliance.

A shaft for a dental screwdriver configured to be inserted into a bore cavity of a dental prosthetic. The shaft has a drive tip for driving a dental screw used to fix the dental prosthetic to the dental implant when the shaft is inserted into the bore cavity of the dental prosthetic. The drive tip is made of a shape memory smart alloy. The shaft also has an axial shaft portion made of a shape memory smart alloy with different material characteristics than the shape memory smart alloy of the drive tip. The axial shaft portion is configured to elastically bend from an original shape to a bent shape along the axial shaft portion without imparting a bending action and torqueing forces along the drive tip when the dental screwdriver is inserted into the bore cavity of the dental prosthetic.

A patient support apparatus includes a plurality of primary sensors adapted to measure different parameters used in the control of the patient support apparatus. One or more suites of secondary sensors are added to the patient support apparatus to provide data about the primary sensors. The secondary sensors may be used to detect errors in the primary sensors, to modify outputs from the primary sensors, and/or to provide usage and/or diagnostic data about the use of the patient support apparatus. The suite(s) of secondary sensors may measure parameters that affect the outputs of one or more of the primary sensors. In some embodiments, the suite(s) of secondary sensors include one or more dormant sensors that are not used on the patient support apparatus until a code modification is received from one or more external sources instructing the control system of the patient support apparatus to begin using the dormant sensor(s).

Non-sliding orthodontic appliances may include an archwire having male fasteners for locking in place with brackets in a non-sliding manner and interproximal loops for exerting forces on the brackets. Appropriate forces may be calculated according to vectors between initial and ideal tooth positions. The brackets may be transferred to a patient's teeth using indirect bonding trays which contain slots for holding and aligning each bracket. The trays may include integrated handles for facilitating handling, may be sectioned into smaller pieces for easier application, and/or may be labeled for facilitating proper registration. Superposition of a digital placement plan and clinical model after bonding may illustrate the accuracy of bracket placement. The archwire may comprise atraumatic ends to avoid patient discomfort. A color registration system can be used to facilitate the attachment of the archwire to the brackets. The archwire may be locked into place with the brackets using crimpable stops.

[Object] To provide, for a composite resin (CR) having a wide range of applicable colors (shades) (wide-ranging color applicable CR), such as a CR having light diffusion properties and a CR that produces color by means of a structural color, a technology with which an excellent effect, specifically, an increased breadth (number) of applicable shades in comparison to an existing CR other than a wide-ranging color applicable CR, can be achieved.

[Solving Means] For example, in a demonstration instrument, a plurality of samples is prepared, a single wide-ranging color applicable CR has been used to restore a cavity in artificial teeth each having a different shade, the cavity being formed at a predetermined position of the artificial teeth, and the plurality of samples is disposed side by side and fixed on a display surface of a display plate, thereby making it possible to compare/contrast conditions of restored portions of the samples to each other and the color tone applicability thereof to those of a teeth to be restored.
