Title (EN) DENTAL MODEL AND PROCESS OF MAKING SAME
(FR) MODELE DENTAIRE ET PROCEDE DE FABRICATION
Abstract:
(EN) A dental model (10) and articulation system are disclosed. The dental model (10) comprises cast mold material (14) formed around an elongate pin or rod (12). A longitudinal tapered pim or rod (12) is embedded in the model during pouring of the casting material (14). The pin or rod (12) extends longitudinally through the base of the model beneath the teeth impressions of the model. The pin or rod (12) can be removed from the model (10) and the model (10) can be cut into several sections or dies. These sections or dies can then be reassembled back on the pin or rod (12) in the precise, true relationship that exists in the model (10) prior to the model being cut into sections. The extending ends of the pins or rods (12) can be removably attached to a flexible member (30) such that models (10) of the upper teeth and lower teeth of a person's jaws can be moved in lateral or protrusive movement and back to centric occlusion.
(FR) L'invention décrit un modèle dentaire (10) et un système d'articulation. Le modèle dentaire (10) est constitué d'une matériau moulé (14) disposé autour d'une broche ou d'une cheville allongée (12). La broche ou la cheville longitudinale et conique (12) est noyée dans le modèle pendant le coulage du matériau moulé (14). La cheville ou broche (12) traverse la longueur de la base du modèle, au-dessous des empreintes dentaires du modèle. On peut retirer la broche ou la cheville (12) du modèle (10) et découper celui-ci en différentes sections. On peut ensuite réassembler lesdites sections sur la broche ou la cheville (12) selon la relation réelle et précise existant dans le modèle (10) avant que celui-ci ne soit découpé en sections. On peut fixer les extrémités saillantes des broches ou chevilles (12) de façon amovible à un élément souple (30), afin de pouvoir imprimer aux modèles (10) des mâchoires supérieure et inférieure d'une personne un mouvement latéral ou protrusif et revenir à une occlusion centrale.
