简要总结
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.
