Brief summary
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.
Detailed description
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.

Masking
SINGLE (Investigator)
Masking description
patients were allocated in a 1:1 ratio using an on-site computer software system with concealed allocation through sequentially numbered, opaque, sealed envelopes (SNOSE). This was a double-blind study, so neither the statistical analyst nor the patients were aware of the surgical procedure

Inclusion criteria
* The study included patient with deficient posterior maxilla with less than 6mm of bone height confirmed by a pre-operative tomographic scan. All healthy (ASA I, II) non- smoker patients were eligible for the study. The absence of uncontrolled diabetes, systemic illnesses, sinusitis, immune deficiency disorders, were also required for inclusion.
Exclusion criteria
* Patients with sinus infection, neoplasm or a large cyst of the sinus, or those who previously underwent a Caldwell-Luc surgery for the same surgical site were excluded
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| radiographic appraisal of gain in alveolar bone height | 6 months | 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. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| incidence of membrane perforation | Until the end of the operation | incidence of membrane perforation during the operation was assessed in both groups |
