An implant or endoprosthesis suitable to be implanted in human or animal tissue includes two (or more than two) parts to be joined in situ. Each one of the parts includes a joining location, the two joining locations facing each other when the device parts are positioned for being joined together, wherein one of the joining locations includes a material which is liquefiable by mechanical vibration and the other one of the joining locations includes a material which is not liquefiable by mechanical vibration and a structure (e.g. undercut cavities or protrusions) suitable for forming a positive fit connection with the liquefiable material. The joining process is effected by pressing the two device parts against each other and by applying ultrasonic vibration to one of the device parts when the two parts are positioned relative to each other such that the two joining locations are in contact with each other.

Embodiments described herein are related to pellets that are placed within an extraction site that is in need of bone augmentation and preservation. The pellets are typically cylindrical in shape and comprise a material and a polymer coating. The goal of the pellets are to encourage sufficient new bone growth that jaw bone deterioration is prevented. The pellets create, arrange, and assemble an ideal growth environment for new bone growth to rapidly grow and preserve the original contours of an individual's jaw bone.

A retainerless orthodontic dental implant system for positioning the mandible forward relative to the maxilla and for facilitating optimal airflow during sleep and a method of using such a system.

An augmentation method is provided, wherein a thermoplastic augmentation element is subject to mechanical energy impact and mechanical pressure by a tool so that augmentation material of the augmentation element is liquefied and pressed into hard tissue to augment the hard tissue, wherein in at least one axial depth, the augmentation element is segmented as a function of the circumferential angle so that at this axial depth the circumferential wall of the initial opening in first regions is in contact with the augmentation element and in second regions is not in contact with the augmentation element.

The invention provides a method for dental restoration including direct modification or customization of a final abutment inside the patient's mouth. The final abutment is made from a non-titanium material. The final abutment, after being completely modified or customized, may then be used to support a crown. The invention exhibits numerous merits such as simplified procedure, cost-effectiveness, reduction of laboratory adjustment, reduction of chair time, and reduction of dentist office visits.

A dental implant, having a central cavity and a strength adjusting structure, is provided. A first opening of the central cavity and a second opening of the strength adjusting structure are both located on a top surface of the dental implant. The strength adjusting structure is located between the central cavity and a side surface of the dental implant. A ratio of a first depth of the strength adjusting structure in a length direction of the dental implant to a second depth of the central cavity in the length direction of the dental implant is greater than 0 and less than or equal to 0.8.

The invention relates to a dental prosthesis production device and method of manufacturing a dental prosthesis in which the dental prosthesis has an implant (40) and an abutment (10) which has a shape that is compatible with the implant (40) and on or to which abutment a dental structure (28) that is made of a dental material, in particular ceramic and/or plastic, and produced with the aid of a CAM process using rapid prototyping or compression molding technology can be secured. The abutment is mounted on the implant (40) via a releasable connection, in particular a screw connection (44), having an anti-rotation mechanism (50), and an anti-rotation device (groove 22) is formed between the abutment (10) and the dental structure (28). A selection device (66) is provided for abutments, said selection device allowing a selection of the abutment (10) for producing the dental prosthesis, optionally after reducing the abutment height to a specified value in a patient-specific manner, and a machining tool, in particular a milling cutter, or a CAM device is provided for shortening the abutment (10).

Dental device (1) for ridge preservation around the socket (2) of an extracted tooth and for promoting jaw bone regeneration inside the socket (2) of the extracted tooth, the dental device (1) comprising: a screw (3) which is entirely made of a biodegradable material to eliminate the need for a removal surgery, wherein the screw (3) is adapted for tight fixation within the jaw bone (4) in the socket (2) to prevent micromovements during bone-tissue regeneration, wherein the screw (2) has a length such that its top is, in the inserted state, flush with the alveolar ridge (5) around the socket (2) to promote full bone regeneration inside the socket (2), and wherein the screw (3) has a hollow (6) and pores (7), wherein the diameters of the pore (7) is substantially equal to or larger than 20 micrometers.

A dental prosthetic assembly includes an additively manufactured semi-flexible reinforcement bar and a polymer and glass outer layer chemically luted to the semi-reinforcement bar outside of the reinforcement bar. The semi-flexible reinforcement bar forms an interior of the dental prosthetic assembly and at least a portion of the polymer and glass outer layer forms teeth of the dental prosthetic assembly. A coupling system of a dental prosthetic assembly includes pins disposed in openings extending into the dental prosthetic assembly and implant abutments configured to be coupled with a mouth of a patient. The implant anchors have horizontal holes configured to receive the pins. The pins secure the dental prosthetic assembly to the implant abutments by moving into the dental prosthetic assembly through the openings and into the holes of the implant abutments.

A dental implant for implantation in the jawbone for the purpose of fastening a superstructure. The implant includes an implant body that extends between a coronal and an apical end and which defines an enossal outer surface. The implant body defines a cavity that is open coronally as well as at least one exit opening from an inside to the enossal outer surface. An outer thread is shaped on the implant body. A thermoplastic element is moreover present in the solid condition and is arranged in the cavity or introducible into the cavity, wherein the thermoplastic element can be brought into an at least partly flowable condition by way of applying a pressing force, which is directed apically into the cavity, and mechanical oscillations and can be pressed through the at least one exit opening into surrounding tissue on account of the pressing force.
