Sinus LiftingNCT07753057
Graftless Lateral Sinus Lifting Using Peizo Electric Device in Patients With Atrophic Maxilla
A study testing lateral sinus lifting with guide and conventional lateral sinus lifting in people with Sinus Lifting, run by Alexandria University at 1 site in Egypt.
Trial summary
Background: Dental implant therapy in the posterior maxilla may be difficult owing to limited bone height after dental extraction with sinus pneumatization. Several approaches for sinus floor elevation have been documented, and hence lateral sinus lifting using surgical guide is used. Read more about this study

About this study
Official title: Guided Versus Conventional Graftless Lateral Sinus Lifting Using Peizo Electric Device in Patients With Atrophic Maxilla [a Randomized Controlled Clinical Trial]
Background: Dental implant therapy in the posterior maxilla may be difficult owing to limited bone height after dental extraction with sinus pneumatization. Several approaches for sinus floor elevation have been documented, and hence lateral sinus lifting using surgical guide is used.
Aim of the study: To compare between guided and conventional sinus lifting using piezoelectric device in patients with atrophic maxilla.

Methods: This study will be carried out as a randomized controlled clinical trial; patients will be randomly allocated into two groups: in the study group 15 patients will undergo lateral sinus lifting using surgical guide, while in the control group 15 patients will undergo conventional sinus lifting without surgical guide with simultaneous implant placement.
Clinical evaluation including intraoperative assessment of duration of surgery and immediate complications such as perforation of Schneiderian membrane, arterial laceration and trauma to adjacent roots and nasal bleeding. Primary implant stability will be measured immediately after implant placement

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
lateral sinus lifting with guideProcedure or surgery
Including 15 patients who will be treated by lateral sinus lifting using a surgical guide with simultaneous implant placement.
conventional lateral sinus liftingProcedure or surgery
including 15 patients who will be treated by conventional lateral sinus lifting without using a surgical guide with simultaneous implant placement.
| Study group | Role | What they receive |
|---|---|---|
| Test Group | Experimental | Not described Receives: Procedure: lateral sinus lifting with guide |
| Control Group | Active comparator | Not described Receives: Procedure: conventional lateral sinus lifting |
What is being measured
The primary outcome is the main question the study is designed to answer.
implant stability
- Secondary implant stability will be measured 6 months post-operatively using Osstell device.
Measured: 6 months
change in pain scores
- Post operative pain will be assessed through a 10 point visual analogue scale (VAS). (0-1=none, 2-4=mild, 5-7=moderate, 8-10=severe)
Measured: up to 7 days
Post operative edema
it will be assessed in the 1st week as following:
- None (no swelling)
- Mild (intra oral swelling confined to surgical field)
- Moderate (extra oral swelling in the surgical zone)
- Severe (extra oral swelling spreading beyond the surgical zone)
Measured: 1 week

Questions about this trial
What is this clinical trial studying?
A study testing lateral sinus lifting with guide and conventional lateral sinus lifting in people with Sinus Lifting, run by Alexandria University at 1 site in Egypt.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 4 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 7 Aug 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Egypt. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
implant stability (time frame: 6 months). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 7 Aug 2026.
