FIG 7-26 SMT technique. (a) Initial cavity in a maxillary second molar. (b) Applying the first increment. (c) In this case, it was decided to apply three increments. (d) Compressing the added composite. (e to g) Removing excess composite with a pointed instrument. (h to k) Simultaneous modeling of three uncured increments. (l to s) Occlusal and lateral views of marginal adaptation with a moistened microbrush. (t) Outcome of adapting the composite increment. (u to x) The increments applied for marginal ridges are built up in the same way: application, compression, removal of excess, and adaptation. (Note that the color saturation of these increments is purely for educational purposes.) (y to aa) Adaptation can be carried out using brushes with natural bristles. (bb) Increment for the oblique ridge. (cc and dd) The center of the increment is compressed with a pointed instrument to define the central depression. (ee) Increment for the oblique ridge following adaptation using a brush. The central and distal space is still open. (ff and gg) An increment is used to prolong the mesial marginal ridge septum. Another is used to model the distal marginal ridge. (hh and ii) The central fossa can be sealed by extending the palatal cusp. (jj and kk) Prolonging a secondary ridge is another way of adding volume to a fossa.
