EVALUATION OF MAXILLARY SINUS LIFTING AND SIMULTANEOUS IMPLANT PLACEMENT USING BONE DENSIFICATION AND ACTIVATED PLASMA ALBUMIN GEL (CASE SERIES STUDY)

Abstract

Background: Implant placement in the maxillary posterior region is challenging due to sinus pneumatization and poor bone quality. Traditional sinus lifts are invasive and carry risks like membrane perforation. A less invasive, safer, and more reliable method for sinus elevation and implant placement is needed for patients with limited bone height. Objectives: This study evaluates transcrestal maxillary sinus lifting during implant placement in the posterior maxilla. The technique involves using Densah burs in combination with activated plasma albumin gel to assess clinical and radiographic outcomes. Materials and Methods: Transcrestal sinus lifting was performed using Densah burs and activated plasma albumin gel during implant placement in six patients with 3-5 mm of residual bone height and missing maxillary premolars or molars. Cone Beam Computed Tomography (CBCT) scans were taken before the procedure and after six months to assess outcomes. Bone height and density around the implants were analysed using OnDemand 3D software. Results: Over six months, there was a significant increase in mean bone height, with an average gain of 5.3 ± 0.70 mm. Bone density around the implants also improved notably, reaching an average value of 255.15 ± 95.69. The sinus membrane remained intact throughout the procedures. Additionally, no statistically significant difference was detected between primary and secondary implant stability. Conclusion: Combining Densah burs and plasma albumin gel in transcrestal sinus lifting is safe and effective, leading to significant bone gain and improve bone density without post-operative complications. Implant stability was consistently maintained, demonstrating the reliability of this technique.
