Obtenção de enxerto ósseo da região retromolar para reconstrução de maxila atrófica
Retromolar region´s bone graft making reconstruction
maxilary’s atrofic

With the advent of osseointegrated implants the treatment of total or partial edentulous individual became
a viable option, and with foreseeable prognostic. In this study, we searched the use of the biometric practice
to evaluate the height and thickness increase with the use of autogenous bone graft, having mandibule’s
posterior region as donor site, with the purpose of a maxilla’s partial reconstruction. For that, 39 individual
submitted to this type of reconstruction integrated the research. The grafted areas were submitted to
biometric analysis, before the graft’s accomplishment and after the graft’s fixation, were obtained that
served to comparison after a period of six to ten months from the accomplished graft, date in which
new measures were taken on the second surgical time (reopening), carrying out an statistical analysis
between the obtained measures, before and after a period included in six to ten months. The biometry
was through measure registrations with manual thickness gauge, below the hexagonal screw’s, and by
photographs registration during and after the measurements. The results allowed evaluating the retromolar
region’s autogenous grafts behavior, showing that a minor resorption difference happened around the
screw. However, there were not problems as for the autogenous bone grafts cicatrization, concluding that
the retromolar region’s bone graft is viable, not compromising the osseointegrated implants installation,
making possible its installations in grafted area.
