摘要： An apparatus for obtaining an image of a tooth having at least one light source providing incident light having a first spectral range for obtaining a reflectance image from the tooth and a second spectral range for exciting a fluorescence image from the tooth. A polarizing beamsplitter in the path of the incident light from both sources directs light having a first polarization state toward the tooth and directs light from the tooth having a second polarization state along a return path toward a sensor, wherein the second polarization state is orthogonal to the first polarization state. A first lens in the return path directs image-bearing light from the tooth toward the sensor, and obtains image data from the portion of the light having the second polarization state. A long-pass filter in the return path attenuates light in the second spectral range.

摘要： A dental light comprises at least one light emitting diode light source configured to produce a light beam and at least one collimating lens system situated to receive the light beam. The collimating lens system is configured to collect and collimate the light beam. The collimating lens system can additionally modify the beam through controlled diffusion or shape the beam using an aperture.

摘要： A dental laser treatment system includes a treatment laser beam and a pilot (e.g., aiming/marking) laser beam sharing a collinear beam path, where the beam path is guided by a guidance system through a handpiece/main chamber assembly having a beam exit. A laser beam presence detector is removably affixed to or within the handpiece/main chamber assembly. The laser beam presence detector provides feedback to a computer which can control actuation of the treatment laser beam and the pilot laser beam, and the beam guidance system. The computer performs a search for determining the center location of the beam exit based on the feedback and controls the beam guidance system to guide the beam path approximately to the center of the beam exit, thereby providing automatic alignment of the laser beam with the beam exit or an optional hollow waveguide.

摘要： Drills for dentistry, which, in a dental implant treatment, enables two or more holes to be bored at a predetermined angle and interval in a minute space in which a single tooth grows and enables treatment to be performed precisely and rapidly regardless of a skill level of a dentist, wherein an arrangement is provided where a first member provided with a drill body and a second member provided with a fixing needle intersect slid-ably at a predetermined angle, the drill body is installed in a direction perpendicular to an axial direction of the first member with its tip facing a direction in which the fixing needle is provided, the fixing needle is installed in a direction perpendicular to an axial direction of the second member with its tip facing a direction in which the drill body is provided, the drill body bores a first hole, bored obliquely with respect to a natural tooth growing direction, and a second hole facing the first hole mutually at a predetermined angle, and the second hole is bored by the drill body upon inserting the fixing needle in the first hole, fixing the second member to the jawbone, and sliding the first member with respect to the second member, fixed to the jawbone, as a reference.

摘要： A device for guiding a dental-surgical hollow bur during a bone extraction, having a template that can be fixed in the region of a extraction point and having at least one guiding means arranged on the template, wherein the guiding means guides the hollow bur such that only a portion of the distal edge of the hollow bur can be brought into contact with the bone. Furthermore, a method for producing such a device is specified.

摘要： A system for dental tissue treatment includes a system for directing a laser beam to an area of dental tissue to be treated, and a fluid-delivery system for directing and controlling a flow of a fluid. The fluid is directed to at least a portion of the area to be treated and the fluid flow is controlled to substantially prevent both a change in laser energy absorption by the dental tissue and attenuation of treatment efficiency due to fluid interference with the laser beam. The fluid present in at least a portion of the area to be treated may prevent or reduce the likelihood of melting of enamel in that area.

摘要： A method for planning a root canal treatment of a tooth which includes a cavity of a patient. The method includes measuring a surface of the cavity with an optical three-dimensional method to generate three-dimensional measurement data of the cavity. A 3D-model of a guide template is planned based on the generated three-dimensional measurement data. The 3-D model is designed in its dimensions as a counterpart to the cavity. Three-dimensional volume data of the tooth is displayed. A position and an orientation of a root canal of the tooth is determined based on the three-dimensional volume data of the tooth. A guide opening for a tool is planned to expose the root canal. The guide opening is arranged within the guide template so that the guide opening points at an entry point of the root canal and in an entry direction of the root canal.

摘要： A method of implementing a splint device, and associated splint device, are provided for a guidance system of a surgical robot. A splint body includes first and second stabilizing portions extending from opposed lateral sides of a medial portion, and defines a U channel. The medial portion, or the medial portion and one of the stabilizing portions, defines a bridge portion extending along the U channel. A partition member, received by the bridge portion, extends into and longitudinally along the U channel. An adhesive material is engaged with the splint body, within the U channel. The U channel is engaged about a tooth or jaw of a patient, and urged toward the tooth or jaw, such that the partition member engages the tooth or jaw and separates the adhesive material into a first portion engaged with the first stabilizing portion and a second portion engaged with the second stabilizing portion.
