A computer is used to create a plan for repositioning an orthodontic patient's teeth. The computer receives an initial digital data set representing the patient's teeth at their initial positions and a final digital data set representing the teeth at their final positions. The computer then uses the data sets to generate treatment paths along which the teeth will move from the initial positions to the final positions. | ||||||

The invention relates to a method and a device for measuring of the shape of an object being measured, in order to provide a supplementary object connected to the shape of the object being measured, wherein the object being measured is provided on its surface with a pattern of fluorescent substances. The surface of the object with the pattern is illuminated with a first type of light (13a, 13b) with a wavelength which excites the fluorescent paint substance used. The pattern is registered by means of optical reading units sensitive to the excited fluorescent light with registration of the same parts of pattern from mutually different directions. The surface of the object is illuminated with a second type of light (15a-15d). The registration of the appearance of the surface of the object is performed during illumination with the second type of light. Calculation of position and shape of the parts of the pattern are made from the registrations of the pattern, and the position for the gradient changes in the surface shape of the object calculated from the registrations of the appearance of the surface, and a three-dimensional shape with interfaces, connected to the object being measured, at the gradient changes is calculated for the supplementary object. | ||||||

A method for manufacturing a dental prosthesis, wherein the shape of the prepared part of the teeth in question is established by scanning at least a part of the teeth, or a replica thereof, by means of a three-dimensional scanner. In order to be able to determine the desired shape of the prosthesis, it is necessary to know not only the shape of the part of the teeth in question, but also the circumferential edge of the preparation, i.e. that part of the teeth which has been prepared for receiving the dental prosthesis. The preparation line is made visible to the scanner by providing the teeth at one side of this preparation line with a coating which the scanner is capable of recognizing. |

For use in making dental restorations, a model is prepared by taking an intra-oral impression and molding in the impression a replica model (30) made from a thermosetting resin (33) and a thermoplastic resin (32). The thermosetting resin provides a tough, heat- and abrasion-resistant surface. Heat from the molten thermoplastic resin accelerates the curing of the thermosetting resin. |

For the production of a core for a root-filled prepared tooth the root canal (11) of the prepared tooth (10) is filled with an impression material (27) which is injected at the bottom of the root canal to successively fill the root canal from the bottom thereof and outwardly under expulsion of air therefrom. The injection is carried out with the aid of an injection needle (23) with an injection syringe cylinder (24) with piston (25) attached thereto, the cylinder being filled with said impression material and the injection needle serving as reinforcing element for the impression material, permitting extraction of the cast from the root canal after the impression material has set. In addition to the injection needle with the syringe cylinder and piston attached thereto the apparatus may comprise a mould (13, 14) formed as a guide for the injection needle (23) and adapted to be applied to the prepared tooth (10) for taking a simultaneous cast of the root canal (11) and the free prepared tooth surface (12) of the tooth. |
