Methods: A total of 67 areas in 13 systemically healthy patients (mean age: 27.16+ 3.84) were analyzed after treatment with the MARF technique. The treatment areas consisted of a minimum of 3 and maximum of 4 adjacent teeth with a minimum of 0.5 mm and a maximum of 2.0 mm of attached gingival on each tooth.
Results: The results of the present study suggest a significant increase in the apico-coronal dimension of the keratinized tissue ranged from 2.26 to 4.51 mm and the increase in attached gingiva ranged from 1.09 to 3.57 mm (P<0.05).Gingival recession decreased significantly in the treated areas and probing depths in the treated areas decreased significantly too (P<0.05).
Conclusions: Modified apically repositioned flap is an effective technique in increasing the apico-coronal dimension of the keratinized tissue and attached gingiva. This technique offers considerable advantages over other mucogingival surgery techniques: simplicity, limited chair time for the patient and the operator, low morbidity because of the absence of palatal donor tissue and predictable tissue color match.
