Minimally invasive maxillary sinus elevation using balloon system: A case series.

The posterior maxillary segment frequently exhibits insufficient bone mass to support dental implants. Sinus floor augmentation enables implant placement in the posterior maxilla. This case series included ten sites, in which sinus floor elevation was done using sinus lift balloon system followed by augmentation utilizing irradiated cancellous bone allograft. Postoperative radiographic assessment of vertical bone gain was done at 3 and 6 months follow-up period. The mean initial and final bone height were 6.16 and 10.50 mm, respectively, with a mean increase of 4.34 mm at 6 months being observed with nil complication. The presented technique might represent a viable alternative for sinus elevation in posterior atrophied maxilla. Irradiated cancellous bone allograft can be advocated as an ideal bone graft material for sinus augmentation procedures.
