The maxillary resorption is often an issue for the installation of osseointegrated implants without first having to resort to bone grafts or reconstructive surgeries. Maxillary reconstructive surgeries are certainly the most indicated option in cases of severe resorption. In cases where atrophies are not as critical, one of the techniques we may use is the use of screwable expanders, a more conservative and less invasive technique. By using expanders, the bone tissue is repositioned, with greenstick fractures and lateral bone compaction which, in addition to the bone gain in thickness, also provides a better primary stability. The objective of this paper was presenting a modification of the Summers technique, using screwable bone expanders. This expansion and lateral compaction of the bone tissue, with the use of screwable expanders happen with more control and without discomfort for the patient, the main difference from the technique proposed by Summers.
