What this Trial Is About
Researchers are studying dental implant placement in the atrophic posterior maxilla, a challenging area due to complex bone remodeling and changes in the maxillary sinus and alveolar ridge shape. The study aims to evaluate the long-term success of implants placed after sinus grafting, focusing on the effect of apical implant positioning on bone remodeling, crown characteristics, and patient satisfaction. This observational cross-sectional study also seeks to develop a classification system to help clinicians decide on treatments for atrophic posterior maxilla cases. The study involves partially edentulous patients who have received implant rehabilitation with a sinus lift procedure in the atrophic posterior maxilla. Researchers will analyze patient records and recall patients for clinical and radiographic examination, including bone remodeling measurements, probing depth, bleeding on probing, and assessments of crown bulkiness and height. Patients will also complete a questionnaire about their satisfaction and oral hygiene ease. Digital analysis of 3D cone beam CT scans will be performed to measure bone and crown parameters and simulate bone graft shapes. Participants will be involved in clinical exams, radiographic measurements, questionnaires, and digital imaging assessments. Researchers will monitor peri-implant bone remodeling, probing depth, and bleeding around implants as primary outcomes. Secondary outcomes include keratinized tissue width, crown-to-implant ratio, crown dimensions, emergence angle, and patient-reported outcomes. The study timeline includes data collection, patient recall, statistical analysis, classification establishment, and thesis submission, with study completion expected by mid-2026.

Who Can Participate
Eligibility Criteria
You may qualify if you...
- 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 such as uncontrolled diabetes mellitus, bleeding disorders, recent myocardial infarction, head and neck radiation, and mental disorders.
You will not qualify if you...
- Fully edentulous patients.
- Patients presenting sinus pathologies such as sinusitis or thickening of the membrane.
- Patient smoking more than 20 cigarettes per day.
- Patient taking systemic drugs that could affect bone healing such as immune suppressive drugs and bisphosphonates.
- Patient with systemic disease that contraindicate the surgical procedure such as uncontrolled diabetes mellitus, bleeding disorders, recent myocardial infarction, head and neck radiation, and mental disorders.

Duration - 2 to 4 weeks
Participants are screened for eligibility to participate in the trial.
1 visit (in-person)
Duration - 1 week
Participants who have previously undergone implant rehabilitation with a sinus lift procedure in the atrophic posterior maxilla are recalled for clinical and radiographic evaluation of their implants and prosthetic crowns. This includes measurements of bone remodeling, probing depth, bleeding on probing, crown bulkiness and height, and patient satisfaction through a questionnaire.
