Title (EN) VARIABLE-GEOMETRY MOULD
(FR) MOULE A GEOMETRIE VARIABLE
Abstract:
(EN) A variable-geometry mould comprising: - a first set of needles (13) consisting of a plurality of first needles (14), - a first set of actuators consisting of a plurality of first actuators (16), each first actuator being configured to move a respective first needle between a passive position and a plurality of active positions; - a second set of needles (13') consisting of a plurality of second needles (14'), - a second set of actuators consisting of a plurality of second actuators (16'), each second actuator being configured to move a respective second needle between a passive position and a plurality of active positions; - a control module (20) configured to activate said first actuators and said second actuators so as to arrange end faces (21) of free ends of said first needles and said second needles along a first active surface, substantially reproducing a first dental surface, and along a second active surface, substantially reproducing a second dental surface, respectively, said first dental surface and second dental surface corresponding respectively to the surface of teeth of a first arch and to the surface of teeth, opposite to the first teeth, of a second arch of a patient.
(FR) Moule à géométrie variable comportant: - un premier ensemble d'aiguilles (13) constitué d'une pluralité de premières aiguilles (14), - un premier ensemble d'actionneurs constitué d'une pluralité de premiers actionneurs (16), chaque premier actionneur étant configuré pour déplacer une première aiguille respective entre une position passive et une pluralité de positions actives; - un deuxième ensemble d'aiguilles (13') constitué d'une pluralité de deuxièmes aiguilles (14'), - un deuxième ensemble d'actionneurs constitué d'une pluralité de deuxièmes actionneurs (16'), chaque deuxième actionneur étant configuré pour déplacer une deuxième aiguille respective entre une position passive et une pluralité de positions actives; - un module de commande (20) configuré de manière à activer lesdits premiers actionneurs et lesdits deuxièmes actionneurs de manière à disposer des faces terminales (21) d'extrémités libres desdites premières aiguilles et desdites deuxièmes aiguilles suivant une première surface active, reproduisant sensiblement une première surface dentaire, et suivant une deuxième surface active, reproduisant sensiblement une deuxième surface dentaire, respectivement, lesdites première surface dentaire et deuxième surface dentaire correspondant à la surface de dents d'une première arcade et à la surface de dents antagonistes aux premières dents d'une deuxième arcade d'un patient, respectivement.
