An implant-supported denture placement and alignment system may include a denture apparatus. The denture apparatus may have a denture base and a denture base positioning system. The denture base may be connectable to implants. Moreover, the denture base positioning system may position the denture base in substantially the same position as a surgical guide used to place the implants. In this manner, the denture apparatus may be positioned so that it is mountable to the implants placed according to the surgical guide following their placement in a patient's mouth. In this manner, variations in the placement of the implants arising during the process of installing the implants may be compensated by transferring the actual implant positioning to the denture apparatus when it is positioned by the denture base positioning system.

The invention relates to methods for preparing a three-dimensional digital model of a prosthetic denture base for fabrication using a light-based three-dimensional printing apparatus. A virtual reference model of a prosthetic denture base is prepared and manipulated to establish specific spatial orientation and angular inclination with respect to the build platform surface of the printing apparatus. Methods may include performing a corrective digital scaling process on the virtual reference model in order to achieve further improvements to dimensional accuracy in the fabrication of prosthetic denture bases.

The present invention relates to an occlusal vertical dimension reproduction method for denture fabrication and, more specifically, to an occlusal vertical dimension reproduction method for denture fabrication, wherein three-dimensional scan data is used to calculate the occlusal vertical dimension required to denture fabrication. The occlusal vertical dimension reproduction method for denture fabrication according to the present invention has an advantage that the occlusal vertical dimension for effectively denture fabrication can be easily determined while minimizing the number of direct scans of the upper jaw and the lower jaw of a patient in an edentulous state or occlusal state to reproduce, in a virtual space, the occlusal state of the oral cavity of the patient wearing denture or denture structure. The occlusal vertical dimension reproduction method for denture fabrication according to the present invention has the effect of reducing inconvenience of a patient and operator during the process of denture fabrication compared to the prior art.

Described herein is a system for hybrid denture fabrication. The system improve the efficiency of the fabrication process for both the dental service provider (e.g., dentist, dental surgeon, etc.) and the patient. A permanent hybrid prosthesis (e.g., the bridge and its reinforcing bar) can be fabricated within 24 hours of the surgical procedure using the system described herein. This makes it possible to deliverer the permanent hybrid prosthesis within 48 hours (or even within 24 hours) of the surgical procedure. Additionally, the system eliminates the need to provide the patient with a temporary denture following the surgery. Further, the system substantially reduces the patient's chair-time and/or the number of patient visits.

A dental prosthesis having a prosthesis base and a set of teeth, namely a full set of teeth or a partial set of teeth, is provided, wherein the prosthesis base comprises at least one dental recess for receiving the set of teeth, and wherein the set of teeth is glued into the at least one dental recess by an adhesive. In the dental recess and/or in or at the set of teeth an adhesive channel is configured which extends along the at least one dental recess or the dental arch in its main direction of extension. It starts at an adhesive filling opening whose configuration is adapted to a filling element.

A dental restoration device includes a sleeve having an exterior surface and an interior pocket that is at least partially filled with a dental cement, and a crown having an exterior surface and an interior surface that is mated to the exterior surface of the crown and bonded thereto by an adhesive disposed between the exterior surface of the sleeve and the interior surface of the crown.
