Background: The use of hydrodynamic piezoelectric techniques for trans crestal / internal sinus lift with simultaneous implant placement has gained popularity as a safe and minimally invasive technique for managing the posterior edentulous maxilla, particularly in cases with sinus pneumatization. This method offers a controlled elevation of the Schneiderian membrane while reducing the risk of perforation compared to conventional techniques. Additionally, it minimizes postoperative discomfort and oedema, leading to better acceptance and satisfaction by the patients. In contrast to traditional osteotome tapping procedures, the hydrodynamic piezoelectric technique enhances surgical outcomes while preserving vital anatomical structures, making it a superior alternative in implant dentistry. This study aims to evaluate the use of the hydrodynamic piezoelectric technique in internal sinus lifting with simultaneous implant placement in comparison to the conventional osteotome technique.

Exclusion Criteria:
-

Change in pain scores
Pain will be evaluated, using visual analogue scale (VAS) as follows: (0-1= None, 2-4= Mild, 5-7= Moderate, 8-10= Severe).
Time frame: at 7, 14, and 21 days
Change in wound healing
The wound healing will be assessed based on the Modified Healing Index. The Wound Healing Index (WHI) evaluates preimplant soft tissue wound healing with scores from 1 to 3. On this scale, a score of 1 indicates ordinary healing with the absence of gingival edema, erythema, suppuration, patient discomfort, and flap dehiscence. A score of 2 indicates ordinary healing with slight gingival edema, erythema, patient discomfort, and flap dehiscence, but no suppuration and a score of 3 corresponds to poor wound healing with significant gingival edema, erythema, patient discomfort, suppuration, and flap dehiscence, or any suppuration
Time frame: at 7, 14, and 21 days
change in implant stability
Implant Stability Quotient (ISQ) will be measured during the operative stage, while the secondary stability quotient will be measured 6-months post-operative during the prosthetic phase preparation using Ostell device.
Time frame: baseline and 6 months
Change in Alveolar Process height gain
The baseline residual alveolar bone height will be measured in the preoperative scan from the alveolar crest to the maxillary sinus floor. Immediate postoperative alveolar bone height will be measured to outline the effectiveness of sinus membrane elevation using CBCT
Time frame: baseline and 6 months
Plan to share: No
