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

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.

The clinical case is a 47 -year-old female patient with a resin mobile prosthesis, 3,5 mm bone width and 16-13 mm bone height, as proved by the 3D model.

After flap tracing and separation of the two cortical parts of the crestal bone through expanders, six immediate-load implants were inserted. CONCLUSIONS: Clinical and radiographic examinations two months after loading confirm the therapeutic success.
