INTRODUCTION: Rehabilitation of the maxilla using implants is frequently problematic because of the pneumatization of the maxillary
sinus into the alveolar ridge. When only a few millimeters of augmentation are needed in conjunction with simultaneous implant placement,
an indirect sinus lift is effective. This study describes transcrestal sinus lift using the sinus balloon technique and DASK (Dentium Advanced
Sinus Kit) drills for implant placement in patients with an atrophic maxillary posterior area with synthetic bone graft, to evaluate the bone
height achieved and the implant success rate.
OBJECTIVES: To evaluate clinically and radiographically the simultaneous implant placement and grafting with synthetic bone graft after
Schneiderian membrane elevation using the maxillary sinus balloon technique and DASK drills.
MATERIALS AND METHODS A total of 13 patients with missing posterior maxillary teeth (premolars or molars) and with limited bone
height below the floor of the maxillary sinus received an implant and grafting with synthetic bone graft after maxillary sinus lifting using a
maxillary sinus balloon technique and DASK drills.
RESULTS: Cone beam computerized tomography 6 months postoperatively showed statistically significant increase in bone height and
density. The mean preoperative vertical bone height value was (5.97 ± 1.17 mm), while the mean 6 months postoperative vertical bone height
value was (10.45 ± 1.56 mm). The mean preoperative implant bone density value was (349.6 ± 1265.9 HU), while the mean postoperative
implant bone density was (771.1 ± 239.1 HU).
CONCLUSIONS: Sinus balloon and DASK drills are an acceptable tool for indirect sinus lifting with simultaneous implant placement.
