Gingival recession (GR) is frequently associated with deterioration in dental esthetics and
dental hypersensitivity. Outcomes from recent systematic reviews have demonstrated that when
the root is covered and the gain in the width of keratinized tissue (KT) is expected, the use
of subepithelial connective tissue grafts (SCTGs) associated with coronally advanced flaps
(CAF) appears to be more predictable, and may be considered the gold standard procedure.
However, the SCTGs may increase patients' morbidity (e.g., pain). This occurs because of the
need for a donor surgical area, which may increase the risk of surgical complications like
bleeding, as well as increases post-operative discomfort and the period of the surgical
procedure. Another biomaterial, a new collagen matrix (CM) has been used as a substitute for
the SCTG. The use of CM was associated with a significant reduction in post-operative
morbidity, less post-operative pain and discomfort in the patient, and more esthetic
satisfaction.
