On account of these observations, a novel surgical technique was presented in literature (Caiazzo et al. 2010)14, with the name of Buccal Plate Augmentation (BPA). After performing a gentle tooth extraction and verifying the integrity of the alveolar walls, BPA consists in placing a HA-based bone graft material over the intact buccal bone plate, underneath the soft tissues and the periosteum in a surgically created pouch with the aim to maintain or augment crestal volumetry and soft tissue aesthetics of the region. This approach allows for avoiding recession of the alveolar facial wall without interfering with the natural healing mechanism of the extraction socket, which is left undisturbed. To date, however, there is still no evidence regarding the most suitable biomaterial for maintaining predictably crestal volumetry and soft tissues contour overtime.
