Title
(EN) DENTAL MODEL HOLDING SYSTEM
(FR) SYSTÈME DE MAINTIEN DE MODÈLE DENTAIRE
Abstract
(EN)
A fixture plate includes a base having a contact face configured to support a dental model having a model identifier on a bottom surface. A bore extends through the base to one or more channels formed in the contact face and that extend from the bore. A viewing port extends through the base and has a transparent material inserted therein to seal the viewing port at the contact face. The viewing port and the transparent material enable the model identifier to be accessed from underneath the contact face when the dental model is on the contact face. A protrusion extends from the contact face and is configured to interface with an aperture of the dental model to retain the dental model in a specific orientation. The channels are configured to provide a suction force applied through the bore to hold the dental model against the contact face.
(FR)
L'invention concerne une plaque de fixation qui comprend une base ayant une face de contact conçue pour supporter un modèle dentaire ayant un identifiant de modèle sur une surface inférieure. Un alésage s'étend à travers la base vers un ou plusieurs canaux formés dans la face de contact qui s'étendent à partir de l'alésage. Un orifice de visualisation s'étend à travers la base et comporte un matériau transparent introduit en son sein pour sceller l'orifice de visualisation au niveau de la face de contact. L'orifice de visualisation et le matériau transparent permettent d'accéder à l'identifiant de modèle depuis le dessous de la face de contact lorsque le modèle dentaire est sur la face de contact. Une saillie s'étend à partir de la face de contact et est configurée pour faire interface avec une ouverture du modèle dentaire afin de retenir le modèle dentaire dans une orientation spécifique. Les canaux sont conçus pour fournir une force d'aspiration appliquée par l'intermédiaire de l'alésage afin de maintenir le modèle dentaire contre la face de contact.
