AIM

To compare the clinical results of treatment of patients with multiple gingival recessions class I and II according to Miller using the modified coronary advanced flap (MCAF) technique in combination with collagen matrix (CMX) and connective tissue graft (CTG).

MATERIAL AND METHODS

The study included 20 patients with Class I and II Miller gum recessions in the area of 136 teeth. Recessions were divided into 2 groups, the first group was operated with a MCAF+CMX combination (test group), and the second one using MCAF+CTG (control group).

RESULTS

Complete root closure was achieved in 87% of the teeth in the test group and 95% of the teeth in the control group (p<0.05). At 6 months the complete root coverage observed in 85% in the test group and 97% in the control group. The average width of the attached keratinized gum had an increase in values 3 mm in the test group and 3.3 mm in the control group. The recession depth decreased in both groups, but in the test group, the residual recession depth was 1.2 mm, and in the control group 0.7 mm. The thickness of the keratinized gum increased from 1.1 mm to 1.7 mm in the test group, and from 1.1 mm to 1.8 mm in controls. Surgery duration and postoperative pain in the test group were significantly lower compared to the control group.

CONCLUSION

The use of collagen matrix with cross-linked collagen can be an alternative to SST and can also be used in cases where it is not possible to use the donor resource of the palate. However, the use of collagen matrix leads to a lower growth of keratinized attached gingiva and does not always contribute to the complete elimination of gingival recessions.
