TRANSCRESTAL MAXILLARY SINUS FLOOR ELEVATION USING THE BALLOON TECHNIQUE WITH SIMULTANEOUS IMPLANT PLACEMENT

Abstract

INTRODUCTION: Rehabilitation of the maxilla using implants is frequently problematic because of the pneumatization of the maxillarysinus 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 AdvancedSinus Kit) drills for implant placement in patients with an atrophic maxillary posterior area with synthetic bone graft, to evaluate the boneheight achieved and the implant success rate.OBJECTIVES: To evaluate clinically and radiographically the simultaneous implant placement and grafting with synthetic bone graft afterSchneiderian 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 boneheight below the floor of the maxillary sinus received an implant and grafting with synthetic bone graft after maxillary sinus lifting using amaxillary sinus balloon technique and DASK drills.RESULTS: Cone beam computerized tomography 6 months postoperatively showed statistically significant increase in bone height anddensity. The mean preoperative vertical bone height value was (5.97 ± 1.17 mm), while the mean 6 months postoperative vertical bone heightvalue was (10.45 ± 1.56 mm). The mean preoperative implant bone density value was (349.6 ± 1265.9 HU), while the mean postoperativeimplant 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.KEYWORDS: Transcrestal approach, sinus balloon technique, DASK drills, implants.
