Abstract: A direct resin veneer (2) for creating a veneer on a tooth surface comprising a thin planar expanse of an uncured restorative material, or direct resin veneer (4). The veneer (4) has a generally tooth configuration that is generously sized to permit adequate coverage for any tooth. Adhered to at least one side of the restorative material is a flexible pliant non-sticky planar sheath (6). The sheath (6) material has a curved gingival arch contour (10) for gum line alignment and various tab-like protrusions that permit placement upon a tooth. An inferior peeling tab (12) allows for sheath to be separated from the resin veneer (4) subsequent to tooth surface placement. And the lateral grasping tabs (16) permit delivery to a tooth's surface.
Abstract: There is disclosed a medical handpiece, in particular a dental handpiece, having a lighting device which includes at least one optical semiconductor element, whereby the at least one optical semiconductor element is arranged at least partially in the interior of the handpiece and is detachably connected to the handpiece. On account of this design, it is possible for the user to easily connect the handpiece to an optical semiconductor element that is needed for a certain treatment and has, for example, a certain desired power level and/or emits a desired wavelength. The handpiece may thus be used for different applications without requiring any additional components such as switches, etc., that take up space. The outside dimensions of the handpiece remain substantially unchanged in comparison with known handpieces.

Abstract: A dental handpiece having a grip with a head in which a treatment tool may be detachably attached. A front casing portion of the grip is continuous to a rear casing portion at an obtuse angle. A first rotary shaft is rotatably supported in the rear casing portion. A cylindrical jacket extends from the head and is arranged in the front casing portion toward the first rotary shaft. A second rotary shaft is rotatably supported in the jacket, and is operatively connected to the treatment tool at one end and to the first rotary shaft at the other end via a gear. The rotary shafts transmit driving force to the head section to drive the treatment tool. The jacket is provided with an engagement groove on its circumferential surface. An engaging device disposed in the rear casing portion detachably engages the groove, thereby fixing the jacket in the front casing portion.
Abstract: The invention relates to manufacturing a surgical guide to be placed in a patient's mouth. The patient's mouth is scanned to obtain surgical-region scan data at a region where an implant is to be located. The patient's mouth is also scanned in the opened position to acquire dental conditions opposite from the surgical region so as to obtain opposing-condition scan data. A virtual model is developed using the surgical-region scan data and the opposing-condition scan data. Using the virtual model, a surgical plan is developed that includes the location of the implant to be installed in the patient. A virtual surgical guide is also developed based on the surgical plan. The dimensions of instrumentation to be used with the surgical guide are checked to ensure they will fit within the mouth by use of the opposing-condition scan data. After checking, final surgical-guide manufacturing information is obtained for manufacturing the surgical guide.

Abstract: An endodontic probe is used to perform disinfection procedures on target tissues within root canal passages and tubules. The endodontic probe can include an electromagnetic radiation emitting fiber optic tip having a distal end and a radiation emitting region disposed proximally of the distal end. According to one aspect, the endodontic probe can include a porous structure that encompasses a region of the fiber optic tip excluding the radiation emitting region and that is loaded with biologically-active particles, cleaning particles, biologically-active agents, or cleaning agents for delivery from the porous structure onto the target tissues.

Abstract: A standard orthodontic retainer is modified on its surface opposite the palate and facing the patient's tongue with a light, a small battery to provide power for the light means, and a frame beneath the light that allows a template to be removably slid into the frame. The template consists of a design such as a heart, a letter of the alphabet, a symbol, or other design that, when the light is activated, shines the pattern onto the top of the tongue of the user. The template can be made so that the design displayed on the user's tongue is of any desired color or color combination. Alternatively, the color of the displayed design may be created by the color of the light or by an additional template consisting of an optical filter providing the desired color.
Abstract: A method treating a root canal in a tooth by introducing into the pulp chamber of a tooth and pulsing a laser light into the fluid reservoir so as to disintegrate pulp within the root canal without generation of any significant heat in said liquid fluid so as to avoid elevating the temperature of any of the dentin, tooth, or other adjacent tissue more than about 5° C.

Abstract: A laser tip, and method for the use thereof, is described for utilization in medical and dental applications. Specifically, a tip with an increased photoacoustic wave emission capability is formed by beveling the tip and further enhanced by stripping the adjacent sheath. Preferably, this conic and/or stripped tip section is surface modified, for example, by texturing, derivatization or metalization. In the field of endodontics the tip is inserted into a solution that has been introduced into a root canal and the pulsed laser is fired. The resulting generation of an enhanced photoacoustic wave propagates through the solution. These photoacoustic waves turbulently clean the interior of the root and lateral canal systems and/or causes cell lysis and dissolution of inorganics in biotic systems.

Abstract: A method and a device for effecting the cordless retraction of the gingival sulcus tissue that includes a dam shaped to be fitted onto a tooth. In one embodiment, the well of the dam is pre-filled with a predetermined amount of a flowable retraction material having a heavy viscosity or putty consistency. The preloaded tooth dam is fitted to a prepared tooth so that when pressure is applied onto the tooth dam, the retraction material is displaced under pressure and forced into the sulcus, causing the gingival tissue to retract away from the tooth to enlarge the gingival sulcus. In another embodiment the cap is filled with a dilatant material. In another embodiment, the cap is filled with an impregnated compressible porous material. In yet another embodiment, the cap is pre-dosed with an astringent or hemostatic agent.
