The present invention refers to a system of prosthetic components consisting of Compensatory Slanted Copings and Abutments of Universal Coupling that function as a set of coupled parts that allow corrections of slants that vary between OQ and 60Q, of fixing osseointeg rated implants, including zygomatic fixations, and it provides a cap, molding transferer and screws for fastening and locking. This system of copings and abutments provides properties of conversion and extension of the implants. Its shape provides better occlusal stability and favorable biomechanics, since the forces are better distributed, diminishing the concentration of tension on the fitting platform of the implant, as well as the screws. The abutments of the universal coupling can be readjusted and be cemented or screwed. In the present system, the superior platform of the coping and the inferior base of the abutment are universalized, since the inferior platform of the coping corrects the slant of the implant. It has screws for fastening and for locking of the coping/abutment set. The characteristics of this system provide great versatility, which allows it to be used in various areas of medicine.

Root canal abutment devices and methods which facilitate the adjustment or removal of an oral appliance, e.g., a crown or bridge, from a reconfigurable abutment assembly are described. The adjustable abutment assembly may be secured within a pulp chamber of a pre-existing tooth. The abutment assembly has a projecting abutment portion with one or more shape memory alloy sleeves or plates or elements extending along the abutment. Each of the sleeves has a length with at least one curved or arcuate portion. Energy may be applied to the elements such that the arcuate portion flattens to allow for the oral appliance to be placed thereupon while removal of the energy allows the elements to reconfigure into its curved configuration thereby locking the oral appliance to the abutment. Removal of the oral appliance may be effected by reapplication of energy to the elements.

A dental implant fixture comprises: a body; a continuous thread part including a continuous thread continuously formed in a spiral shape along an outer circumferential direction of the body; a bone damage prevention part formed at one end portion of the body and preventing an alveolar bone existing in an opening area of a hole where the body is implanted from being damaged due to the continuous thread part; and an entrance guide part provided at the other end portion of the body and guiding the body in an initial implantation entrance direction. The entrance guide part comprises; a flat portion of horizontal flat; an inclined portion extending upward from a circumferential surface of the flat portion with an upwardly increasing radius; and a rounded portion connecting the inclined portion and the continuous thread part and having at least one area inwardly rounded toward the centerline of the fixture.

Embodiments include a scanbody that includes a base that fits in an anti-rotation geometry of a dental implant, and a body that is set to be scanner. The body includes a lateral surface with geometrical elements that allow the identification of information regarding a position, direction and rotation of the scanbody. The body lateral surface does not include any flat portion and includes a first opposing trunconical element, base-to-base, a secondary trunconic element and concave surfaces disposed at the side, including a hole (5) that receives a fixing screw.

A system for increasing organic cell regeneration in a cellular medium includes an electromagnetic (EN) field generating device adapted to produce a constant EM field of less then 1 mT at a radiation frequency of substantially 7.69 Hz, which comprises at least one coil and is adapted to generate the EM field so that the cellular medium is substantially within the generated EM field. A resonance medium is also provided for locating substantially at or adjacent the cellular medium, wherein the resonance medium comprises a composition which is adapted to resonate at the frequency of The EM field generated by the device, wherein the composition is a biologically active composition containing at least a composition comprising crystalline structure minerals.

The present invention relates to a connection between a post part provided for being screwed into the jawbone and an associated superstructure part to which a dental prosthesis can be fastened. The connection between the post part and the superstructure part has a rotational self-centering action, wherein at least one of the surfaces provided for this purpose has a friction-minimizing modification and/or coating.
