The difference in time usage involving the two matrix systems is especially since in the circumferential matrix system, no clamp was applied, although in the sectional matrix system, it consisted of the clamp which was needed to hold the matrix set up along with the clamp had to be equipped inside the cervical location of the principal enamel which Typically have marked cervical constriction.
transferring the surface area smoothness from the Mylar to the ultimate restoration. By developing a 270° wrap seal in the tooth planning, the matrix creates subgingival regions which can be clean, doing away with the need for tricky operator shaping and ending.
