Sponsor's own description
Objective: To conduct a systematic mid-to-long-term efficacy evaluation of the small window lateral maxillary sinus floor elevation surgery, using the ratio of the window area to the volume of bone graft material as an innovative evaluation metric; to provide clinical evidence for the treatment and assessment of maxillary sinus elevation surgery. Research Content and Methods: The study included all patients who underwent lateral wall small window surgery performed by Dr. Xie Liangkun from 2017 to 2024 in Affiliated Stomatology Hospital of Kunming Medical University. Seventy-seven patients underwent cone-beam computed tomography (CBCT) at each stage before grafting, before the surgery,immediately after the surgery, 6 months postoperatively, and after tooth placement. The CBCT data were imported into Mimics software to measure the volume of bone graft material at different periods (b value), and The photos which recording window size during surgery were imported into ImageJ software to measure the window area (a value). CBCT was also used to measure the distance from the window to the sinus floor, the thickness of the lateral wall bone plate, and the thickness of the Schneiderian membrane as secondary measurement indicators. The ratio of a/b was statistically analyzed for correlation with various secondary indicators, and conclusions were drawn. Bone cores taken 6 months after grafting (before implant placement) were subjected to Micro-CT scanning and histological analysis to evaluate the bone formation effects.
