A device for cranial restructuring, by the expansion, compression, or flexure of a cranial structure located between first and second anchor points, includes: a force generator configured to generate force; a first anchor attachment to the first anchor point; a second anchor attachment to a second anchor point; a hydraulic force transmitting structure, connected to the force generator, to transmit the generated force to the anchors thereby putting the cranial structure in tension, compression or flexure. Another device for cranial restructuring includes: a head support, having a head-receiving portion; a force generator to generate force which is periodic; a first anchor attachment to the first anchor point; a force transmitting structure, connected to the force generator, which transmits the periodic force to the anchor in a restructuring direction; wherein the head support includes: a restriction to prevent or restrict movement of the user's head when the periodic force is applied.

An automatic sampling apparatus for taking liquid samples for the qualitative or quantitative determination of at least one analyte contained in the sample liquid includes a sample line that can be fluidically connected to the sampling station, a pump device, at least one sample container that can be fluidically connected to the sample line, and an electronic control system. The electronic control system is configured to fluidically connect the sample line to the sample container such that a fluid flow path extending from the sampling station through the sample line into the sample container is formed. The electronic control system is further configured to transport, using the pump device, a definable volume of the sample liquid, in the form of a liquid sample, along the fluid flow path into the sample container. The sampling apparatus is configured for concentrating or extracting the analyte present in the liquid sample.

A surgical distance adjusting assembly for a distractor has a base having a first connecting portion configured to hold a first bone attachment member and a carrier having a second connecting portion configured to hold a second bone attachment member. The base and the carrier are movable relative to each other, wherein the first and second connecting portions provide a releasable mechanical coupling to the first and second bone attachment members. The releasable mechanical coupling comprises a hook member at one or both of the first and second connecting portions and configured to engage the respective bone attachment member. Alternatively, the releasable mechanical coupling comprises an opening at one or both of the first and second connecting portions. The opening has a thread for a fixation screw configured to releasable couple the respective bone attachment member to the respective connecting portion.

A special tube is disclosed for the insertion of materials inside the maxillary sinus in order to displace the Schneiderian membrane. The tube is connected to a source of a flowable material. The tube is inserted through the alveolar ridge beneath the maxillary sinus and when the flowable material is advanced through the tube the Schneiderian membrane is lifted. The tube can be part of a dental implant which is screwed inside the alveolar ridge.

An orthodontic screw and a set of elements for forming an orthodontic or orthopedic appliance for dentistry, as well as a method for making an orthodontic or orthopedic appliance for dentistry. The orthodontic screw includes two bodies connected by positioning elements designed to allow the distance between the bodies to be adjusted; the bodies have a seat adapted to receive a portion of a connection structure associable with the orthodontic screw for its connection to the teeth of a dental arch; the seat has a groove formed on an external surface of the bodies, so that said portion of said connection structure can be inserted in the seat through a displacement orthogonal to the same seat.

The present invention relates to the field of devices and methods for distraction osteogenesis, and, more particularly, to distraction devices and distraction systems used in the treatment of mandibular or maxillary alveolar ridge atrophy, and to methods for utilizing a distraction device or a distraction system for bone tensioning.

A system (1) for modifying a human or animal bone (2) is intended to reliably enable bone augmentation or bone reduction of the bone (2) to be treated in a particularly simple and, in particular, also particularly well-tolerated manner. For this purpose, according to the invention, a two-dimensionally extended lifting/pressure element (4) for insertion between the periosteum (6) of the bone (2) to be treated and the underlying bone (2) or the overlying connective tissue and a control element (10) associated therewith are provided, the control element (10) being designed to exert a magnetic pressure or tensile force on the lifting/pressure element (4).

The present invention relates to the field of devices and methods for distraction osteogenesis, and, more particularly, to distraction devices and distraction systems used in the treatment of mandibular or maxillary alveolar ridge atrophy, and to methods for utilizing a distraction device or a distraction system for bone tensioning.

A fixation clamp for use in an external fixation system for holding bone fragments adjacent to each other with the help of fixation elements has at least one clamping assembly having a pair of jaws with at least two different size grooves to accommodate a bone fixation element such as a pin or rod. An alternate clamping assembly has at least three grooves wherein at least two of the grooves have a different size adapted to accommodate a correspondingly sized bone fixation element such as a bone pin. The longitudinal axes of the grooves define a polygon. The jaw pairs can be rotated about a central longitudinal axis to present different size reception cavities towards the pins or rocks depending on their diameter.
