The present invention includes apparatuses and methods for making a final hybrid prosthesis to be attached to one or more dental implants. One preferred method includes the step of making a temporary hybrid prosthesis and at about the same time also making a duplicate temporary hybrid prosthesis. The duplicate temporary hybrid prosthesis permits the final hybrid prosthesis to be made with fewer visits to a restorative dentist and with less dental laboratory time than is currently needed when making a final hybrid prosthesis.

Casting jigs, methods, and kits that may be used in manufacture of anatomical healing caps. A casting jig may include a body having one or more wells within the body, each well being open at a proximal end thereof and having a negative shape corresponding to an anatomical healing cuff body of a given tooth position. The casting jig includes an opening through the bottom surface through which an elongate handle may be inserted, allowing a temporary abutment to be coupled into the distal end of the elongate handle, so that the abutment is disposed in the well, held in place by the handle, as it is used as a core about which the anatomical healing cuff body is formed. A crown forming jig for forming an inexpensive, chair-side prepared bis-acrylic temporary crown that may be easily and quickly installed over the anatomical healing cuff body is also disclosed.

Casting jigs, methods, and kits that may be used in manufacture of anatomical healing caps. A casting jig may include a body having one or more wells within the body, each well being open at a proximal end thereof and having a negative shape corresponding to an anatomical healing cuff body of a given tooth position. Each respective anatomical healing cuff body negative shape includes an asymmetrical cross-section and an irregular surface so that an anatomical healing cuff body having said shape is configured to provide substantially custom filling of at least an emergence portion of a void where a natural tooth once emerged or should have emerged from the void (e.g., in the case of a congenitally missing tooth). The casting jig may further include a socket at a distal end of each well that is configured to receive therein a dental implant or dental implant analog.

An approach is disclosed that involves creating an updated master dental model of a patient's mouth after an implant surgery by aligning new postoperative oral scan data to pre-existing preoperative oral scan data that is more comprehensive (e.g., it includes bite registration). Before surgery a multi-piece stackable surgical guide set is created using the preoperative oral scan data. The surgical guide set is used to facilitate the surgery. After the surgery at least one piece of the surgical guide set is placed back in a patient's mouth and may act as a reference marker because it was created using the preoperative oral scan data, but is also part of the postoperative mouth configuration since it was used to facilitate the surgery. The affected portion of the mouth may then be digitally scanned directly or indirectly by way of a physical impression with the reference marker in place to determine the new characteristics resulting from the surgery such as new implant installation locations and orientations. The new postoperative oral scan data may be combined with the pre-existing preoperative oral scan data by way of the reference marker (since it is a constant between the two sets of scan data) without having to do such things as take a new bite registration, on which a new implant restoration can be easily created.

A dental article includes a shell defining a volume, the shell including a circumferential base and an incisal/occlusal region distal from the circumferential base. A hardenable dental composition is located within the volume of the shell, and an isolation film is located at the circumferential base of the shell.

A dental prosthesis having a guide hole formed therein. The guide hole is configured to guide a drilling for a screw, and configured to receive the screw, holding the prosthesis in place when screwed into the bone of a patient.

The invention relates to a method for producing a denture base semi-finished product with the following steps: 1) Recording and digitalizing the oral cavity situation of a patient, wherein a digital three-dimensional oral cavity model of the patient is produced, or providing a digital three-dimensional oral cavity model of the oral cavity situation of a patient; 2) Implementing a first calculation in which a digital three-dimensional first model (A) of a denture base is calculated, wherein the oral cavity model of the oral cavity situation is used as a basis for the first calculation; 3) Conducting a second calculation, in which a digital three-dimensional second model (B) of a denture base semi-finished product is calculated from the first model (A) of the denture base, wherein volume is added at least in sections to the three-dimensional model (A) of the denture base; and 4) Producing the denture base semi-finished product with a Rapid Prototyping method, wherein with the Rapid Prototyping method, a CAM method is used and the digital three-dimensional second model (B) of the denture semi-finished product is used as the basis for the CAM method. The invention also relates to a device for implementing such a method and a denture base semi-finished product produced using such a method.

To provide try-in dentures which make it possible to adjust a bite more easily with high accuracy, a denture base part 12; a dentition part 13; an adjustment part 15; and a base part 14 are included, the adjustment part and the base part being separable from each other, and the adjustment part includes all of occlusal surfaces 13b of the dentition part, and a face 15a parallel to an occlusal plane 10a, the adjustment part being formed so that a movement of the adjustment part parallel to the occlusal plane with respect to the base part can be performed, a rotation of the adjustment part in the face parallel to the occlusal plane can be performed, or both the movement and the rotation can be performed.

Disclosed is a method for determining the relative arrangement of patient's jaws in a bite position when the patient's occlusion is not defined by natural teeth alone, where the method includes a step of obtaining a digital 3D representation including both surface data relating to dental tissue in one of the patient's jaws and surface data relating to a scan appliance arranged in relation to the jaw, where the scan appliance is configured for at least partly defining the patient's occlusion.
