Where should the assembled Tofflemire be placed in relation to the gingival margin?

The correct placement of the assembled Tofflemire in relation to the gingival margin is one to one and a half millimeters below the gingival margin. This positioning is crucial for several reasons.

Firstly, placing the Tofflemire slightly below the gingival margin helps ensure that the matrix band effectively forms a tight seal around the tooth. This is essential for creating a proper contact point between the restored tooth and adjacent teeth, as well as for preventing excess material from spilling into the gingival tissue during the restorative process.

Secondly, the positioning allows for adequate space for the dental material to be packed and shaped without compromising the health of the gingiva. If the matrix band were placed too high or at the level of the gingival margin, it could irritate the gingival tissue and potentially lead to inflammation or damage.

Overall, this specific placement supports achieving an optimal restoration while simultaneously safeguarding the periodontal health of the surrounding tissues.
