Connection of a prosthesis structure with an implant structure
A set is disclosed that includes a connection device for connecting a prosthesis structure with an implant structure or a capped tooth, the connection device having a retention insert and a holding shell. The set also including a mounting tool for mounting and demounting the retention insert of the connection device to and from the holding shell of the connection device such that a retention rim of the retention insert is moved in towards its central axis when a demounting head of the mounting tool is arranged within a space between an outer surface of the retention rim of the retention insert and an inner surface of a holding rim of the holding shell allowing the retention insert to be released from the holding shell.

Retention insert and connection device for dental applications
b) of the retention edge (11) directed away from the end face (12), a substantially axial slit (14) extends through the retention edge (11) and the end face (12) to the opening (121) of the end face (12). Connected to the opening on the end face, the slit of the retention insert according to the invention is a relatively simple structure which ensures that the retention insert, and in particular the retention edge thereof, has an elasticity sufficient for snap-fitting it onto the head or the patrix head. At the same time, a spring force from the snapped-on retention edge can therefore act on the head, such that the retention insert and parts connected thereto are clamped on the head. Moreover, this retention edge and this opening also have the result that imprecisions in the position of the implant structure, and in particular lack of parallelism, and also the effects of forces from different directions can be compensated, without the retention insert or parts thereof being substantially squeezed or similarly deformed.

Connection of a prosthesis structure with an implant structure
A connection device includes a holding shell and a retention insert. The retention insert has an end side and a substantially ring-shaped retention rim projecting therefrom. The holding shell has an end side and a substantially ring-shaped holding rim projecting therefrom. An outer surface of the retention rim is at least partly spaced from and adjacent to an inner surface of the holding rim when the retention insert is arranged in the holding shell and when essentially no radial forces are acting on the holding rim and on the retention rim. In that the outer surface of the retention rim and inner surface of the holding rim are at least partly not contacting each other when essentially no radial forces are acting, it can be achieved that the retention insert is connected relatively loosely with the holding shell when the connection device has not yet been placed on the implant structure.

METHOD FOR DESIGNING A TOOTH REPLACEMENT PART, METHOD FOR WORKING A DESIGNED TOOTH REPLACEMENT PART, TOOTH REPLACEMENT PART, AND COMPUTER-READABLE MEDIUM
The invention relates to a method for designing a tooth replacement part, which is intended to be able to be mounted on a residual tooth area and in which a spacer (1) is provided between the tooth replacement part (2) and the residual tooth area (3), and the subsequent step of testing whether one or more undercuts (4) are present in the tooth replacement part. The invention further relates to a method for working a designed tooth replacement part with one or more undercuts present, wherein a spacer is provided between the tooth replacement part and a residual tooth area and wherein a form of the spacer is modified in order to remove the undercut or undercuts of the tooth replacement part. The invention also relates to a method in which the formation of undercuts is avoided by provision or modification of a spacer. The invention moreover relates to a tooth replacement part provided with a spacer, wherein the spacer of the tooth replacement part has first and second spacer areas and between these a transition area, with no undercut present in the transition area. The invention also relates to a corresponding computer-readable medium.

A model of the dental restoration is shaped in-vivo on the patient by the dentist. The model is then scanned in the dentists office using a 3D optical scanner. A 3D graphic representation of the model is obtained from the scanner using a computer. The computer is used to convert the 3D graphic representation of the model into a milling path for milling the dental restoration in a block of durable dental restoration material having known dimensions. A mill, also present in the dentists office, mills the dental restoration from the block using the milling path while the patient is waiting. The dentist can then take the milled dental restoration and apply it to the patient in the same, single visit.
