A prospective study investigating clinically and radiologically the effectiveness of the use of a combined hard and soft tissue graft retrieved from the maxillary tuberosity and designed for alveolar ridge preservation following tooth extraction.
Patients scheduled for a single mono-rooted tooth extraction are included in the study. After atraumatic extraction, sockets are filled with a "one-piece" dual tissue graft harvested from the tuberosity using an adjusted trephine. CBCTs are performed before the extraction and 4 months after ridge preservation, to analyze the vertical and horizontal alterations of the ridge, using 'ITK-Snap' software.
Clinical measurements of both soft and hard tissues are also assessed during the extraction and implant placement.
