摘要:
Dental systems and methods related to impressionless dental modeling. A dental modeling system includes a dental model base and a mounting plate. The dental model base includes a plate support surface and a plurality of pin receiving apertures formed in the support surface. The mounting plate includes a plate portion positioned on the plate support surface and a plurality of pins extending into the pin receiving apertures to provide removable attachment of the mounting plate to the dental model base. The plate portion includes a model support surface configured to support a model of a person's teeth. The model may be formed directly on the model support surface using an impressionless technique. The model may be formed separately using an impressionless technique and then bonded to the model support surface.

Die Erfindung betrifft eine Vorrichtung zum Halten eines Models eines Zahnersatzteils, wie etwa eines Abutments, mit einem ersten Bereich, in dem das Modell des Zahnersatzteils aufmodelliert werden kann und einem zweiten Bereich, der eine eindeutige Lageidentifizierung des Halters erlaubt sowie eine Vorrichtung zum Scannen von Objekten, wie etwa Kiefermodellen und/oder Zahnmodellen und/oder Sägezahnmodellabschnitten, mit einem Halter in den eine obige Vorrichtung mit einer eindeutigen Lageorientierung gehalten und abgescannt werden kann. Weiterhin betrifft die Erfindung ein Verfahren zum Erstellen eines digitalen Modells eines Zahnersatzteils, wie etwa eines Abutments, mit den Schritten des Auswerten der Scandaten zur Erfassung zumindest eines Teils der Form des Zahnersatzteilmodells und Auswertung der Scandaten zur Erfassung zumindest der Lage des Halters, einem Datenträger mit Instruktionen zur Ausführung eines solchen Verfahrens sowie einem Verfahren zum Herstellen eines Zahnersatzteils.

摘要:
An objective of the present invention is to provide a holder of an abutment tooth model to surely and accurately set a model of an abutment tooth on a three-dimensional coordinates measuring apparatus when measuring an outer face shape of the abutment tooth model by the three-dimensional coordinates measuring apparatus, where the holder of an abutment tooth model can easily hold an abutment tooth model, and can easily adjust and confirm an accurate position of the abutment tooth model. The holder includes an abutment tooth model holding base 1 and a cylindrical body 2. The abutment tooth model holding base 1 is formed in a pillar shape, has a concave part at the upper side thereof and a holding hole provided at a center of an end face of the lower side thereof for inserting a supporting shaft which projects at a center of a rotating part of a three-dimensional coordinates measuring apparatus, and can attachable/detachable hold the residual ridge side of an abutment tooth model by adhesion with a sticky material built on a bottom face in the concave part thereof. The cylindrical body 2 is formed in a cylindrical shape, and has a lower side thereof having a slightly larger inner diameter than an outer diameter of the abutment tooth model holding base 1 and being externally fitted to the abutment tooth model holding base, a stepped part, which contacts to a part or the whole of upper face of the abutment tooth model holding base 1, and an upper side from the stepped part having a smaller inner diameter than that of the lower side thereof.

The invention proposes a supporting device for the manufacture of dental prosthetic components in the field of dental implants and, more specifically, of connecting elements, which provide a faster, cheaper and dependable technique, and which helps the dentist in his task with the objective of eliminating addition or subtraction operations when using said connection elements. This objective is attained, in accordance with the invention, for the supporting device includes a support component (10) having an orifice (80) with an internal thread and a screw element with an external thread, which mutually engage to constitute a safe support for a machined odontological block to be formatted.
摘要:
Method for the production of a prosthetic article including mounting at least two implants supporting the prosthetic article to be realized, in a model reproducing the user's gum, with the implants along the profile, heating a first implant to fuse an end of a first metallic wire to a first abutment corresponding to the portion emerging from the model of the first implant, heating the wire at a temperature lower than its melting temperature, in order to stretch it between the abutments, so that its development line is substantially parallel to the profile of the model at each point, heating the second implant in order to allow the fusion of the other end the first wire on the second abutment, so as to form a first bridge, and shaping with the technical material the first and the second abutment to form the artificial teeth of the prosthetic article.
摘要:
An assembly for manufacturing dental prostheses includes a set of modular members constituted by a straight bar (2), a curved bar (3), a plurality of cylinders (4) and two end members (5), adapted to be assembled and soldered to each other to form a reinforcement frame of a dental prosthesis, under immediate load and executable within the same day. The method for manufacturing dental prostheses includes assembling the components and mutually soldering them so as to form a rigid reinforcement frame of a dental prostheses that can be applied to the implants inserted previously in the lower or upper arch of the patient.
