the study aims to assess the effectiveness of hydraulic pressure sinus lift via lateral wall approach, versus piezoelectric surgery in patients with deficient posterior maxilla.
This study involves a randomized clinical trial of 20 participants with less than 6 mm bone height in the posterior maxilla in need of Maxillary Sinus Floor Augmentation using the lateral window approach. Patients will be randomly assigned to two groups; the HPLT Group which include 10 patients who will undergo hydraulic pressure for osteotomy preparation for lateral sinus lifting technique, and the PSLT Group which include 10 patients managed using piezoelectric surgery. Clinical and radiographic assessment of bone augmentation, as well as intraoperative biological complications and postoperative complications were recorded.

radiographic appraisal of gain in alveolar bone height
Postoperative radiographic appraisal was conducted by an immediate postoperative CBCT, followed by other one after 6 postoperative month's. Measurements of the bone height was conducted from the alveolar crest to the floor of the maxillary sinus on a cross-section view of the CBCT (Carestream Health, Rochester, NY). Radiographic assessment of the amount of bone height gain in 6 months period was performed by comparing the bone height measurements between the 6 postoperative months' CBCT with the preoperative scan.
Time frame: 6 months
incidence of membrane perforation
incidence of membrane perforation during the operation was assessed in both groups
Time frame: Until the end of the operation
