Core Tip

Core tip: The two bone blocks sandwich technique refers to two autogenous bone blocks harvested from alveolar bone in the maxillary anterior edentulous region, and includes one small bone block and one large bone block. The small bone block is harvested from the apical zone of the large bone block, and it is sandwiched between the large bone block and the palatal bone plate. This technique may be an alternative treatment option in augmenting severe horizontal bone deficiency of the anterior maxilla.
