The advances in oral surgery allowed us to compensate for the anatomical loss which arise from several diseases and cause negative clinical conditions to implant rehabilitation. Among pre-implant techniques there is the split crest: through expanders, it makes rehabilitation possible when the reduced crestal width could be an obstacle

TECHNIQUE:
The expansion technique involves separation of the two cortical parts with prior preparation of the mucoperiosteal flap.
More specifically, the flap is traced with a scalpel and then an osteotomy is performed using sharp-pointed chisels, which create joints to release the forces related to surgery.
Then, with greater osteotomes, we will create a green wood fracture which will increase the transverse diameter of the apical crestal region.

Finally, the alveolus can be prepared for implant fixture insertion.
