Clinical and Digital Evaluation of Implants in the Atrophic Posterior Maxilla Treated with Sinus Lift A Cross-Sectional Study on Bone Remodeling, Prosthetic Outcomes, and Patient Satisfaction

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.
