This article describes alveolar ridge reconstruction in the esthetic zone using autogenous bone blocks harvested from the chin, taking into account the way the bone block is harvested, stabilized, and contoured in the recipient site. The 38 procedures were divided into two groups: group 1, using piezoelectric surgery, and group 2, using rotary instruments.
