摘要： An orthodontic workstation stores a library of virtual three-dimensional brackets in a memory. Each of the virtual brackets has a unique three-dimensional configuration and prescription. Typically, the library of bracket comprises a library of commercially available, off-the-shelf brackets. The workstation further includes an interactive treatment planning program that permits a user to move teeth from a virtual model of the dentition to a proposed set-up. In one possible embodiment, the treatment planning program provides the ability to display a virtual bracket placed on a virtual tooth and change the prescription or configuration of the virtual bracket. The treatment program automatically compares the modified prescription with the prescription information of the virtual brackets in the library and selects a bracket from the library that most closely matches the virtual bracket displayed on the tooth. Thus, the user does not have to use customized brackets. Any deviation in tooth position resulting from a discrepancy between the off-the-shelf bracket and the user-defined bracket can be corrected for by changing the position of the bracket on the tooth or by changing the shape of the archwire.

摘要： Optical scan data including a first set of images representing a first portion of a three-dimensional object is received. A processing device receives ultrasound scan data including a second set of three-dimensional images representing a second portion of the three-dimensional object. The processing device performs image stitching between the second set of three-dimensional images using the optical scan data. The processing device then creates a virtual model of the three-dimensional object based on the stitched second set of three-dimensional images. The images may in particular be intraoral images. Further, an intraoral scanner is described, which comprises an optical imaging device and an ultrasound imaging device at a fixed relative position. An inertial measurement device may be provided to determine the probe orientation.

摘要： A process for preparing a water-soluble, radio-opaque paint for marking acrylic resin dental stents includes the steps of preparing a solution comprising 50 ml of ethanol, 6.4 grams of glycerol, 4.0 ml of benzaldehyde; 1.0 ml of glacial acetic acid, and 0.15 grams of hydroxy propyl cellulose. A radio-opaque powder, such as 50 grams of barium sulfate powder having a mean particle diameter of about 10 mu m, is then added to the solution. The solution is then mixed to obtain the paint, wherein the paint has a uniform dispersion of the radio-opaque powder. This paint may be used on dental stents to locate and guide placement of dental implants. The method may include the steps of preparing a water-soluble, radio-opaque paint for marking dental stents comprising the steps of preparing a solution described above; adding a radio-opaque powder, such as 50 grams of barium sulfate powder; and mixing the solution to obtain the paint, wherein the paint has a uniform dispersion of the radio-opaque powder. The uniform dispersion may be obtained by using ultrasound. Further, the method comprises applying the paint to a dental stent; placing the stent in contact with a patient's teeth; taking a radiographic image of the stent and the patient's teeth. The stent then is removed from the patient's teeth, and the paint is removed from the stent.

摘要： The invention relates to an intraoral scanning device (1) for recording ultrasound scan data in the mouth of the patient, the device comprising: a housing (2) having a proximal portion (4) and a distal portion (6), the distal portion (6) being adapted for placement within the patients mouth; a high frequency sonic head (20) comprising at least one transducer (36) for scanning a covered or non-covered tooth region (90) or residual tooth region (92) and mounted within the distal portion (6) of the housing (2), and means for applying excitation signals to the sonic head (20) in order thereby to produce an ultrasonic wave which passes over at least part of the tooth region (90) or residual tooth region (92) such that the sonic head (20) receives ultrasonic waves reflected by the tooth region (90) or residual tooth region (92) to be scanned. The sonic head (20) is movable at least in a first and a second degree of freedom, and by a drive assembly (22) arranged within the proximal portion (4) of the housing (2) for driving the sonic head (20) in the first and second degree of freedom such that the sonic head (20) is movable in a plane for applying the ultrasonic wave to a pre-determined region of the tooth region or residual tooth region.

摘要： The invention relates to a method and system for reconstructing dental structures, such as dents or residual dents which are at least partly covered by soft tissue, such as gingiva, in a region of interest, the method comprising: providing (201) a surface reflection scan of the dental structures, providing (202) a sub-surface reflection scan of the dental structures, fusing (203-208) the surface reflection scan and the sub-surface reflection scan in order to reconstruct the dental structures, wherein the fusing comprises: segmenting (203) dental tissue from non-dental tissue based on the sub-surface reflection scan, generating (203) a dental model based on the segmented dental tissue, and fusing the surface reflection scan (240) and the dental model (260). The system and method allows for a reconstruction of dental structures which does not rely on gingiva management and which provides for a time efficient data acquisition.
