Abstract:
The invention relates to a blank for the production of a dental shaped body, wherein the blank has a corpus (2) of tooth restoration material, from which the shaped part to be fabricated is carved by means of a tool (4) by removal of material. The blank has coding means (1) formed on part of the surface (6) of the blank corpus (2), which coding means (1) has at least one structure (8, 9) for identification of the blank. The coding means (1) consists of a plurality of panels (5.1) at the level of the surface (6) of the corpus (2) and a plurality of panels (5.2, 5.3) incorporating a flat structure (8, 9) at a level (h1, h2) which is distinguishable from at least the level of the surface (6) of the corpus (2).The invention further relates to a method for identifying a blank with the aid of coding means (1).

Abstract:
The document proposes a diagnostic chewing gum for identifying the presence of pathogens detectable via the mouth, in particular residing in nasal, oropharyngeal, laryngeal, oesophageal, ocular and/or pulmonal tissue of a user, comprising a base material or particles (3) embedded and/or attached to said base material; an element (1, 5-7), like e.g. a releasable flavor molecule, attached to said base material and/or said particles, for the generation of a change in the chewing gum directly detectable by the user; wherein said pathogen is selected from the group consisting of virus, bacterium, protozoa, prion, fungus or a combination thereof; and wherein the element (1, 5-7) generates the change upon direct or indirect contact with a marker (4) which is released by said pathogens, or, in case of a virus or prion, by the cellular structure hosting it.
Abstract:
The brushhead/handle interface includes a brushhead assembly (20) which has a brush member (26) for cleaning teeth. A driveshaft (14) extends from a handle portion (12) of the toothbrush (10), which is driven in an oscillating manner through a selected rotational angle. The driveshaft includes one or more contact regions (49). The coupling member includes an interface portion or portions (46) which are forced against the contact regions of the driveshaft by a single spring member when the driveshaft is inserted into the coupling member. The single spring (34) exerts a sufficient force on the interface portions of the coupling member against the contact regions of the driveshaft to produce both a reliable torque transfer between the driveshaft and the brushhead assembly and to maintain axial retention of the brushhead assembly on the driveshaft during operation of the toothbrush.
Abstract:
An applicator principally for use in the dental profession, for the placement of different materials as may be required. The applicator includes an elongated handle having an applicating end portion formed at the opposed ends thereof which may be either of like or unlike construction, i.e. formed as a brush and/or a flocked applicating end portion. The flock may extend from the distal end a predetermined longitudinal distance over an extended portion. Intermediate the opposed applicating end portion, the elongated handle is provided with a circumscribing groove to define a frangible area by which the user, at his or her option, can cleanly sever the applicator handle to form two separate and distinct applicators. The applicator is also provided with a hinging arrangement adjacent the opposed applicating end portions whereby the applicating end portions may be angularly bent relative to the elongated handle at the option of the user.
Abstract:
A device and method for applying dental composite matter to dental surfaces, such as cavities in teeth, gaps in teeth, or other deformations in tooth surfaces, or other applications to teeth, or appliances and devices used with teeth, such as crowns or inlays/onlays. A hand held powered tool provides oscillation of the composite material after the composite material is grossly applied to the dental surface. The oscillation is at a frequency and amplitude that facilitates uniform spreading of the composite material over the dental surface in a desired pattern, while retarding the tendency of the material to stick to the tool.
Abstract:
In order to select the ultrasonic wave power and amplitude range that matches an ultrasonic tip (130) for mounting on a surgical handpiece (120), the tip (130) includes a cavity (131) forming a housing for an identifier element (140). The identifier element is made of an elastic material presenting a melting temperature higher than 130° C. enabling it to withstand both vibration and sterilization temperatures. The identifier element (140) presents a color or a pattern corresponding to the ultrasonic wave power and amplitude range appropriate for use with the tip.
Abstract:
A handle for a medical instrument includes an elongate structure with a longitudinal axis, a central portion, and at least one end portion configured to receive a working element. The end portion includes a rigid core and a sleeve configured to fit over the rigid core, and the sleeve includes a rounded gripping surface having a substantially circular cross-sectional configuration and an anti-roll structure having a substantially non-circular cross-sectional configuration. The sleeve may further include a groove extending around its periphery and configured to receive a replaceable identifying element, such as a color-coded band or o-ring. The sleeve may also include a slot that intersects the groove and is configured to receive the tip of a tool used to remove the replaceable identifying element from the groove.
Abstract:
The present invention is directed to selection of individual patient archwires by examining the patients inner arch rather than the patients teeth. In particular, a method of archwire selection comprises (a) obtaining a representation of a patient's inner arch curve (a “PIAC”); (b) selecting an archwire shape based at least partially on the PIAC representation; (c) making an initial selection of an archwire size based at least partially on the PIAC representation; (d) selecting a final archwire size after considering something other than the PIAC representation; and (e) selecting an archwire to be used based on the selected archwire shape and selected final archwire size. Using the PIAC rather than the occlusal or labial and buccal surfaces of the teeth for archwire shape selection promotes shaping the teeth to the shape of the jaw bone and gives consistent facial esthetics plus better retention of the treatment correction. Use of a patients PIAC/jaw bone structure also facilitates automating the process of archwire selection.
Abstract:
A dental wedge for use in a dental medical treatment and restoration of hollow spaces associated with caries between neighboring teeth. The dental wedge has a triangular cross-section and a free end running out to a rounded tip. The dental wedge (1) is bent upwardly like a saber. The base face (3) and the side faces (4) of the dental wedge (1) are arched concavely inwardly. The impact edges (5) of the base face (3) and of the side faces (4) of the dental wedge (1) are rounded. The dental wedge (1) exhibits a first, longer wedge section (1a) and a second, shorter wedge section (1b), wherein the impact edges (5) between the base face (3) and the side faces (4) in the first wedge section (1a) are running parallel to each other. The impact edges (5) in the second wedge section (1b) run toward each other toward the free upwardly bent tip (2) of the dental wedge (1).
