Sinus floor elevation with crestal approach and immediately loaded post-extraction implants

Alveolar ridges in the posterior maxilla are often compromised by reduced bone volume. This anatomic condition often limits dental implant placement, mostly because of limited vertical bone availability without prior or simultaneous sinus augmentation. When at least 5 mm of residual bone are present, osteotome techniques are used as a less invasive alternative to the lateral window approach to increase bone volume in the posterior posterior region of the maxillary jaw. Implants are generally placed simultaneously for four to six months after performing osteotome-mediated sinus floor elevation, depending upon the residual crestal bone remaining beneath the sinus floor. However, unlike common indications, in order to shorten the treatment period, this report aims to show a challenging case where, through a thorough surgical protocol, two compromised maxillary teeth were replaced by two immediately loaded post-extraction implants contextually to an osteotome-mediated sinus floor elevation.
