A dental stabilization block intended to be bitten, only on one side of the mouth, between the upper and lower molars and/or premolars of a patient, called teeth, to keep the patient's mouth open during a dental procedure so as to prevent the teeth from meeting, thereby authorizing access to teeth and/or gums on the opposite side of the mouth and at the front of the mouth, without being substantially hampered by the dental stabilization block, the dental stabilization block comprising: - a body, of essentially parallelepiped shape, which comprises, when the dental stabilization block is in place in the patient's mouth, - an upper wall, having an upper outer tightening surface which is designed to come into contact with the upper teeth, the upper outer tightening surface comprising at least a first outlet orifice, - a lower wall, having a lower outer tightening surface which is designed to come into contact with the lower teeth, the lower outer tightening surface comprising at least a second outlet orifice, - a first side wall which is oriented towards the inside of the mouth, - a second side wall which is oriented towards an inner face of the cheek, - a front end wall which is oriented towards the front of the mouth, - a rear end wall which is oriented towards the back of the mouth, - at least a first inner channel which opens out towards the outside of the body at the level of at least the first outlet orifice and/or at least the second outlet orifice, the first inner channel defining a flow path which is configured to be traversed by a bite registration material intended to harden and to be molded at least on the teeth, - at least a second inner channel which opens out towards the outside of the body at the level of an inlet orifice which is configured to receive at least one end portion of a device for injecting the bite registration material, the inlet orifice being disposed on an outer surface of the first side wall and/or the front end wall, and - a first inner junction region which is configured to establish fluid communication between the first inner channel and the second inner channel. - a body, of essentially parallelepiped shape, which comprises, when the dental stabilization block is in place in the patient's mouth, -
