Influence of Residual Bone Height on Marginal Bone Loss Around Implants Following Lateral Sinus Floor Augmentation With Deproteinized Bovine Bone Mineral
Lebanon142 participantsStarted 2026-01-01
Plain-language summary
Data collection will be done on all patients who underwent a lateral maxillary sinus floor augmentation in the Faculty of Dental Medicine, both in the Periodontology Department and in the Oral Surgery Department.
Pre-surgical residual bone height will be measured on patients with a preoperative CBCT, and marginal bone loss will be measured in patients with a postoperative periapical radiograph that dates at least 3 years after implant placement.
In contrast to other studies who only associated between the presurgical residual bone height and implant survival / success rate, this study design takes a more in depth approach and measures the exact marginal bone loss on each implant. In addition, other factors will be taken into consideration (implant type, smoking status, diabetes status) to eliminate any confounding factors.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* All patients who underwent a lateral maxillary sinus floor augmentation using deproteinated bovine bone matrix (DBBM) at the faculty before 2022.
* Patients with pre-operative CBCT.
* Patients with no visible sinus infection in the pre-operative CBCT.
Exclusion Criteria:
* Patients who do not have a pre-operative CBCT.
* Patients who do not have a post-operative orthogonal periapical radiograph that dates at least 3 years after implant placement.
* Presence of inflammatory lesions at the surgical site (eg, sinusitis as assessed by CBCT).
* Cases with sinus perforation.
* History of radiation therapy in the head/neck region.
* Use of bisphosphonates
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
