We recommend following the instructions below precisely because especially in the sintering processes for occlusally very curved restorations the correct bead layer is a decisive factor in subsequent fitting on the model Restoration on sintering bead layer e Only use the sintering trays and beads intended for the respective high temperature furnaces when sintering inCoris TZI e Make sure that the restorations are lying completely on the bed of beads e Remove beads lying interdentally with a probe so that shrinking is unhindered e If several restorations are sintered at the same time these must not touch the edge of the sintering tray or each other Embedded bridge restoration e In order to prevent the sintering beads from sticking e g interdental on the bridge pontic the restorations must not be pressed or embedded into the sintering beads too hard Very occlusally curved bridge restorations lying on buccal restoration side e Position crown and bridge restorations on the occlusal side of the restoration e Very occlusally curved bridge restorations e g Spee s curve are always to be placed on the buccal labial side of the restoration so that the center bend of the restoration is lying on the sintering beads e Use additional sintering beads to support ends of restorations which have hollow areas Non supported bridge restoration with hollow area e Support every restoration pontic with at least one sint
