 Band may be trimmed for the shallower gingival margin permitting matrix to extend farther gingivally

 Matrix Band with the shortest diameter towards the gingival and the one with the wider diameter should be towards the occlusal to conform to the tooth form and to be able to restore contact with the adjacent tooth

 Band should extend approximately 1.0mm beyond gingival wall.

 Occlusal edge of the band should extend no less than 1.0mm but no more than
