Abstract

Background: Tooth extraction is generally accompanied by bone remodeling and pneumatization of the maxillary sinus in the posterior region of the maxilla, which can result in a reduction in the height and width of the bone and compromise the placement of the implant. However, this anatomic deficiency can be restored through maxillary sinus elevation. Among the various surgical methods used, the indirect sinus floor elevation technique is relatively less invasive and less complex.

Aim: Herein, we present the case of a 58-year-old partially edentulous female who underwent rehabilitation of the right maxillary molar region using the indirect sinus floor elevation technique. The hydraulic lift system was used followed by immediate implant placement.

Relevance For Patients: This technique incorporates the advantages of both the lateral wall and crestal approaches for sinus elevation and is associated with a lower incidence of sinus membrane perforation and minimum bone loss.
