Abstract: A dental implant includes an implant body extending along a longitudinal axis between a crown end and an apical end, the implant body having a core along which a helical thread extends with at least one thread, the core being tapered towards the apical end on at least one section of the length of the dental implant. At least two tapping grooves are arranged in the thread. The grooves interrupt the thread, so that the thread includes a series of consecutive thread arcs. Each thread arc has an apical surface oriented towards the apical end of the dental implant, and a crown surface oriented towards the crown end of the dental implant. A peripheral lateral surface connects the apical surface and the crown surface of the thread arc. In at least one section of the dental implant in which the core is tapered, at least one thread arc has a radial offset.

The coronal surface of the thread has, in a cross-sectional view along the longitudinal axis, a second profile repeating according to a coronal pitch.

Abstract: A method for measuring pressure of a gaseous fuel compressed in a feed system of an engine equipping a motor vehicle, by a pressure measuring device having an infrared quality sensor and an electronic control unit, the measuring method being characterized in that it consists in determining a corrected absorbance value of the fuel based on absorbance measurements performed by infrared analysis, at preset wavelengths, and in comparing the value to a nominal absorbance value, determined beforehand based on absorbance measurements performed at a nominal pressure after a pressure stabilization phase of the fuel and at the same said wavelengths, in order to determine the fuel pressure.

Abstract: A set of components for dental prosthetic restoration includes a ceramic dental implant having an internal connecting receiving space. An internally threaded insert is added into the internal connecting receiving space of the dental implant, and rotatably indexed. It is held by a fixing part forming an axial abutment opposing an extraction of the internally threaded insert out of the inner connection receiving space.

Abstract: A dental implant, extending along a first longitudinal axis between a proximal end and a distal end, includes a proximal endosseous section designed to be buried in the patient's jawbone, extended away from the proximal end by a distal implant section designed to emerge from the patient's jawbone, and an inner connection housing extending from the distal end towards the proximal end. The distal implant section extends at a height along the first longitudinal axis towards the distal end from a base to an apex, and flares from the base to the apex away from the first longitudinal axis. The base has a diameter smaller than a diameter of the proximal endosseous section, so as to form a first annular groove. The distal implant section includes an outer surface having a roughness less than or equal to 0.2 ?m. The height at which the distal implant section extends from the base to the apex is between 1.2 mm and 1.5 mm.
