Patent

CA 2216204

A dual dental tray assembly (10) is provided which includes a pliable resilient outer dental tray (14) using a performed thin inner tray (12) of thermoplastic material that nests inside the pliable outer tray. The two are heated to between 145 degrees Fahrenheit to 160 degrees Fahrenheit. During this time the inner tray is more formable, allowing for the inner tray to be accurately formed over the patient's teeth. The outer tray (14) also prolongs the time during which the inner tray (12) is moldable. The outer tray (14) also operates as a seal with the gums to create a better vacuum created by the patient's sucking. Thus, the inner tray (12) once formed and cooled, becomes hard and flexible again and provides a thin hard dental tray as accurate as dental trays produced by dentists in their in their labs on models.

Porte-empreinte dentaire double (10), comprenant un porte-empreinte extérieur (14) élastique et flexible utilisant un porte-empreinte mince préformé (12) de matériau thermoplastique qui s'emboîte dans le porte-empreinte extérieur flexible. Les deux sont chauffés à une température d'environ 145 degrés Fahrenheit à 160 degrés Fahrenheit. Pendant ce temps, le porte-empreinte intérieur est plus formable, ce qui lui permet d'épouser fidèlement les dents du patient. Le porte-empreinte extérieur (14) prolonge aussi le temps de moulage du porte-empreinte intérieur; il forme un joint d'étanchéité avec les gencives pour créer un meilleur vide que celui créé par l'effet de succion du patient. Ainsi, le porte-empreinte intérieur (12), une fois formé et refroidi, redevient dur et flexible et fournit un porte-empreinte dur et mince aussi précis que les porte-empreintes produits par les dentistes dans leur laboratoire sur des modèles.
