Abstract: The present invention relates to a bone regeneration material comprising: a solid first phase of hydroxyapatite of natural origin which is macroporous, having pores of diameters greater than or equal to 50 ?m, this phase of hydroxyapatite is a crystalline solid phase of hydroxyapatite, whose crystals have a size comprised between 20 and 120 nm, and this solid phase of hydroxyapatite has a specific surface area comprised between 8 and 20 m2/g, the method of production and a method of bone repair based on this bone regeneration material.

Abstract: The present application relates to an abutment system (12) and its use. The abutment system (12) comprises: a soft tissue level abutment part (10) adapted to be attached to a bone level dental implant (40) by means of an abutment screw (56), wherein the abutment system is adapted to selectively support both a cement-retained final restoration (66) and a screw-retained prosthetic component (68; 70). The present application also relates to dental methods.

Abstract: The present invention relates to a bone regeneration material comprising: a solid first phase of hydroxyapatite of natural origin which is macroporous, having pores of diameters greater than or equal to 50 pm, preferably pores of diameters between 50 and 100 pm, and a solid synthetic second phase of calcium phosphate intended to enrich said first phase, said second phase having a Ca/P molar ratio of between 0.2 and 2, preferably of between 0.3 and 1.9, preferentially of between 0.5 and 1.65, said bone regeneration material having a defined weight ratio of said solid first phase of hydroxyapatite of natural origin to said solid synthetic second phase of calcium phosphate of between 99/1 and 1/99.

Abstract: Described herein is a method that comprises: —placing a bone material, containing hydroxyapatite and organic substances, in contact with an extraction liquid that gives rise to a first liquid phase, containing the organic substances and possibly impurities extracted from the bone material, and a second solid hydroxyapatite phase, containing the hydroxyapatite; and —separating the liquid phase and the solid hydroxyapatite phase. The extraction liquid is an aqueous extraction solution brought to a temperature between 150° C. and 300° C. and a pressure between 150 kPa and 350 kPa.

Abstract: The invention relates to a dental implant consisting of an anchoring body defined between an apical end and a cervical end, wherein said anchoring body is a body having a first predetermined length and, on the outer surface thereof and along the entirety of said first predetermined length, at least one thread, wherein said anchoring body has, over at least a coronal portion, a portion of said at least one thread that has a nominal diameter that is greater than an outer diameter of said anchoring body at a first ratio of 2.00 to 4.00, preferably 2.00 to 3.00.

Abstract: The invention relates to a trans-mucosal component for a dental implant intended to support a prosthetic installation. The trans-mucosal component has been designed for the purpose of improving the quality and stability of the biological adhesion of the junctional epithelium and of the connective tissue and wherein the trans-mucosal component (2) is provided with a waist-shaped or inwardly narrowed part for reducing the necessary height of the trans-mucosal component and creating a volume for generation of a stabilizing and retentive belt of soft tissue. According to the invention the distance in the longitudinal direction along the contact surface of the waist-shaped or narrowed part should at least correspond to the required, biological width of the adjoining soft tissue.
