The study aims to evaluate the influence of the additional use of EMD in treatment of gingival recession defects using a coronally advance flap (CAF) and a CM (collagen matrix) by means of digital and clinical assessment methods. The reference group comprises patients receiving treatment with CAF and CM without the application of EMD.~In this prospective, randomized, controlled study, recession height and area, width and thickness of keratinized gingiva, pocket probing depth, and the clinical attachment level were measured at baseline and followed-up for one year.~15 patients with 24 gingival recession defects (Recession Type 1 after Cairo/Miller Class I or II) were recruited and were randomly assigned into the two treatment groups.
The clinical trial studies patients with gingival recession defects (receding gums).~The goal of the study is to test whether the additional use of enamel matrix derivatives (EMD), combined with the use of a coronally advance flap (CAF) and a CM (collagen matrix), shows a better outcome compared to a comparison group. The comparison group comprises patients receiving treatment with CAF and CM without the use of EMD.
