| ABSTRACT Sinus augmentation is a reliable treatment option to augment alveolar bone deficiency in the posterior maxilla. Historically, lateral or crestal approaches were the most used techniques. In this study, a sinus floor elevation technique with crestal window sinus lift using magnetic mallet or piezotome was proposed to treat cases of extremely atrophic maxilla (remaining bone height ≤ 3mm). Martial and Methods: 20 patients indicated for sinus floor elevation were divided into two equal groups (group A) in whom the crestal window was prepared and elevated via magnetic mallet while in (group B) sinus elevation was done via piezotome. In both groups, sinus augmentation using human particulate allografts was placed via the crestal access window followed by implant placement 6 months later. Cone-beam computed tomography (CBCT) was done for volumetric and bone density analysis of the newly formed bone in both groups. Results: The newly formed bone height was 7.43 ± 1.4 mm in group A and 6.75 ± 1.3 mm from the baseline to 6 months postoperative allowing insertion of 8.5 mm implants. Bone density was 436.7 ± 99.81 HU in group A and 486.8 ± 106.9 HU in group B. Conclusion: crestal window sinus lift performed with magnetic mallet or piezotome is a predictable procedure for maxillary sinus augmentation in severely atrophic posterior maxilla, where postoperative elevation of bone height can be achieved with minimal intra and postsurgical complications. | ||||
