Patent

CA 2247111

A dental impression tray (10, 10a, 10b, 10c) has wall portions (14, 14b, 14c, 15c) defining at least one channel (16, 16b, 16c) for receiving a quantity of photocurable dental impression material (18). At least one of the wall portions (14, 14b, 14c, 15c) is located next to the chamber (20, 20c) and is made of a material that transmits electromagnetic actinic radiation. The tray (10, 10a, 10b, 10c) also includes a chamber (20, 20c) for receiving a chemiluminescent composition (22). Light emitted from the chemiluminescent composition (22) induces the curing of the impression material (18) in a uniform manner along the length of the channel (16, 16b, 16c).

Une coque d'empreinte dentaire (10, 10a, 10b, 10c) comporte des parois (14, 14b, 14c, 15c) définissant au moins une gorge (16, 16b, 16c) pouvant recevoir une quantité donnée de matière d'empreinte dentaire photoréticulable (18). L'une des parois au moins (14, 14b, 14c, 15c) est disposée à proximité de la chambre (20, 20c) et est constituée d'une matière qui laisse passer un rayonnement actinique électromagnétique. La coque (10, 10a, 10b, 10c) comporte également une chambre (20, 20c) destinée à contenir une composition chémiluminescente (22). Le rayonnement émis par la composition chémiluminescente (22) induit la réticulation de la matière d'empreinte (18) de manière uniforme sur toute la longueur de la gorge (16, 16b, 16c).
