    • The present invention is a system for performing a dental procedure that reduces or eliminates particulates produced during the procedure from being deposited in the mouth of the patient or about the area where the dental procedure is performed. This system comprises, an enclosed dental dam having a semi-rigid upper ring, lower ring and semi-flexible dome. The semi-rigid upper ring has a snap connector along its interior perimeter edge and a first radially outward extending lip along its top side. Then semi-rigid lower ring has a snap connector able to be received by the interior perimeter edge of the semi-rigid upper ring for holding a flexible sheet having an aperture for sealing about a tooth and a second radially outward extending lip. When the upper and lower rings are connected the first and second radially outward extending lips form a snap fit adapter. The semi-flexible dome has an upper surface having at least two apertures and the base having a snap fit adapter along its inner perimeter edge for being received by the groove formed between the radially outward extending lips when the upper and lower rings are connected. One of the at least two apertures is able to receive an air abrasive drill for removing tooth material and the other is able to receive a dental camera for visualizing the tooth during the dental procedure.
    • 本发明是一种用于执行牙科手术的系统,其减少或消除在手术过程中产生的微粒沉积在患者的口中或在牙科手术进行的区域。 该系统包括具有半刚性上环,下环和半柔性圆顶的封闭式牙坝。 半刚性上环具有沿着其内周边缘的卡扣连接器和沿其顶侧的第一径向向外延伸的唇缘。 然后半刚性下环具有能够被半刚性上环的内周边缘接收的卡扣连接器,用于保持具有用于密封齿的孔的柔性片,以及第二径向向外延伸的唇。 当上下环连接时,第一和第二径向向外延伸的唇形成卡扣配合适配器。 半柔性圆顶具有具有至少两个孔的上表面,并且底座具有沿着其内周边缘的卡扣配合适配器,以在上下环连接时由形成在径向向外延伸的唇之间的凹槽接收。 所述至少两个孔中的一个能够接收用于移除牙齿材料的空气磨料钻,并且另一个能够接收用于在牙科手术期间使牙齿可视化的牙科相机。
