Digital planning for implants in the upper back jaw after a sinus lift
Official title: Digital Planning and Clinical Assessment of the Treated Atrophic Posterior Maxilla With a Sinus Lift Procedure: a Cross-sectional Study.
Run by Saint-Joseph University · NCT07526337 · Data updated 2026-11-12
This project will test whether digital planning and the position of implants after a sinus lift affect bone levels, gum health, crown shape, and patient satisfaction in adults with implants in the upper back jaw.

Is this trial a fit for you?
✓Likely a good fit
Adults over 18 with partial tooth loss in the upper back jaw who previously received implant rehabilitation with a sinus lift and who do not have medical conditions that contraindicate oral surgery are ideal candidates.
✕Probably not a fit
Fully edentulous patients, those with active sinus pathology, heavy smokers, or patients taking bone-affecting drugs (e.g., bisphosphonates, immunosuppressants) or with uncontrolled systemic disease are unlikely to benefit from participating.

What this trial studies
This cross-sectional project will examine adults who received dental implants in the atrophic posterior maxilla following a sinus lift, using digital planning records and clinical examinations. Researchers will measure vertical peri-implant bone changes on imaging, probing depths, crown height and emergence profile, and patient-reported outcomes such as satisfaction and food impaction. Subjects will be selected from a university dental clinic and must be partially edentulous with prior sinus grafting, excluding those with active sinus disease, heavy smoking, or systemic conditions that impair bone healing. Data will be analyzed to see whether apical implant positioning after grafting correlates with clinical and patient-centered outcomes.
Why it matters
Potential benefit: If successful, the findings could help dentists plan implant position after sinus grafting to reduce bone loss, improve gum health and crown fit, and increase patient comfort and satisfaction.
How similar studies have gone: Sinus grafting and guided bone regeneration have been used successfully to allow implant placement, but human data specifically examining apical implant positioning after grafting are limited and relatively novel.

Show full inclusion / exclusion criteria
Inclusion Criteria: * \- Patient aged more than 18 years. * Partially edentulous patients having an implant rehabilitation treated with a sinus lift procedure in the atrophic posterior maxilla. * Patient with no systemic disease that contraindicate the surgical procedure as uncontrolled diabetes mellitus, bleeding disorders, recent myocardial infarction, head and neck radiation, and mental disorders. Exclusion Criteria: * \- Fully Edentulous patients. * Patients presenting sinus pathologies (sinusitis, thickening of the membrane). * Patient smoking more than 20 cigarettes. * Patient taking systemic drugs that could affect bone healing as immune suppressive drugs and bisphosphonates. * Patient with systemic disease that contraindicate the surgical procedure as uncontrolled diabetes mellitus, bleeding disorders, recent myocardial infarction, head and neck radiation, and mental disorders.
