The present case involves a 39-year-old nonsmoking patient with multiple recessions at the 2nd quadrant elements, classifiable as type 2 (RT2). Considering that the palate was not conducive to harvesting, taking into account the thickness of the available keratinized mucosa (> 2 mm), the CAF (Coronally Adavanced Flap) technique combined with the grafting of three-dimensional collagen matrix of equine origin was chosen. Following proper opening of the flap, the heterologous collagen matrix, after being beveled with a scalpel, was placed dry in the recipient site and stabilized through suture; the flap was then repositioned coronally and sutured. Follow-up one year after surgery confirmed tissue healing. The reduction in the depth of the recession was satisfactory, and the keratinized mucosa appeared visibly thickened, with a good result in terms of aesthetics as well.
