Abstract: The dispensing gun, for delivering a material from a cartridge, includes a frame having a handle, an injection gate for connecting a cartridge, the injection gate located at the distal part of the frame, a lever including at least two teeth and a piston with at least two notches. The dispensing gun includes a mechanism for directly locking the cartridge on the injection gate; and the dispensing gun includes a mechanism for pushing the piston inside the cartridge so that the material contained in the cartridge is extruded in a single piston stroke; and the dispensing gun is configured so that the lever includes an actuating state in which the first notch of the piston and the first tooth of the lever are engaged together prior to connecting the cartridge so that the lever and the handle form an angle of almost 90°.

Abstract: Hydraulic cements and hardened materials obtained after hydration of the hydraulic cements, especially cements useful in the medical field such as dental cements. In particular, a hydraulic cement including calcium silicate particles and calcium carbonate particles having specific particles sizes. The hydration of the hydraulic cement enables to provide a hardened composite material with reinforcing properties, having calcium silicate particles dispersed in a solid dispersant phase including calcium silicate hydrates (CSH) and porous intergranular areas including insoluble calcium carbonate particles having a d50 granulometry ranging from 1 nm to 1500 nm.

Abstract: A cartridge for dispensing a material, having: a sleeve having a longitudinal axis and a distal wall with a dispensing hole; a barrel defining a chamber for the material, including a proximal open end and a breakable distal wall at its distal end, and being movable in the sleeve between a first position where its distal wall is a distance from the sleeve's distal wall and a second position where its distal wall's sealing portion contacts an inner surface of the sleeve's distal wall; and a piston having a plate movable to seal the barrel's chamber. The sleeve includes an internal piercing element, near the dispensing hole, for breaking the barrel's distal wall upon moving the barrel from the first to the second position. Around the piercing element is an annular cavity delimited peripherally by a beveled inner surface that complements a beveled outer surface of the barrel.

Abstract: A regenerative material in the connective tissues (such as bone, dentin or pulp) regeneration field. More precisely, a connective tissue regenerative material, preferably a bone, dentin or pulp regenerative material, including: a porous polymer matrix having interconnected pores; and non-hydrated calcium silicate particles; wherein: the polymer matrix is anhydrous; the non-hydrated calcium silicate particles have a d50 granulometry, preferably ranging from 0.05 μm to less than the average diameter size of the pores of the matrix; and the non-hydrated calcium silicate particles being coated on the inside walls of the pores of the matrix. Also, a method for preparing the connective tissue regenerative material and uses of the regenerative materials, such as in the dental field; especially, for providing regenerative materials with improved biomechanical and osteoinductive properties (i.e. good migration, adhesion and proliferation of cells; enhanced mechanical properties; and optimal and controlled biodegradability).
