An interventional study of Hydraulic Pressure Lifting Technique and Piezo-Surgical Lifting Technique in Sinus Lifting and Piezoelectric Technique, sponsored by Alexandria University. Completed at 1 site in Egypt. Open to participants aged 20 Years and older. Per ClinicalTrials.gov, last updated 2025-05-04.
Sponsored by Alexandria University · Not applicable, Interventional, and Treatment
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.
Alexandria University is the lead sponsor of 569 studies on the registry; 125 are open to participants now.
Of its 12 completed or terminated interventional studies of FDA-regulated products, 0 (0%) have results posted.

Exclusion Criteria:
patients with posterior deficient maxilla managed with osteotomy for lateral sinus floor augmentation using the Hydraulic Pressure Lifting Technique with A.I drill and hydraulic-powered Aqua-Lifter (OLA system) were assigned to HPLT Group
Device: Hydraulic Pressure Lifting Technique
posterior deficient maxilla managed with osteotomy for lateral sinus floor augmentation using Piezo-Surgical Lifting Technique were assigned to PSLT Group

Hydraulic Pressure Lifting Technique
Piezo-Surgical Lifting Technique
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
