Soft tissue augmentation is a well-established procedure employed in a diverse range of applications such as soft tissue thickening, keratinized tissue augmentation, improvement of the esthetics of existing dental implants and teeth, and crestal bone preservation around implants. This case report describes a technique for the augmentation of vertically thin soft tissue in the lower jaw posterior area. At the time of the implant placement, after measuring the soft tissue thickness, soft tissues were augmented with a porcine accellular dermal matrix (Mucoderm, Botiss Biomaterials, Germany). After 2 months, during the second stage surgery, the implant was exposed and the soft tissue thickness was measured.
