Maxillary sinus floor elevation is a predictable surgical procedure meant to vertically increase the amount of bone in the posterior region of the upper jaw to enable placement of a prosthetic rehabilitation device supported by implants.
Elevation of the maxillary sinus is a recommended technique for edentulous areas of the maxillary posterior region lacking adequate bone.
In that region,
placement of dental implants is required in order to
achieve successful prosthetic treatment.
Different
anatomical situations and different topography of
the sinus with respect to the maxillary ridge give rise
to establishing a classification with respect to the
pneumatization and atrophy or resorption of the subantral maxillary area.

Sinus floor elevation is commonly used in cases where alveolar bone resorption has led to insufficient bone height for the placement of dental implants.
Contraindications to this procedure are: inadequate
sinus transversal dimension, ostium location at
the surgical site, excessive or inadequate interocclusal space, sinus disease, as well as all general
contraindications to dental implant placement.
