Volumetric change after maxillary sinus floor elevation using absorbable collagen sponge: a retrospective cohort study

Year: 2025

Type: article

Abstract: Objectives: : To evaluate changes in bone volume induced by absorbable collagen sponge (ACS) use during maxillary sinus floor elevation and to identify associated factors. Patients and Methods: After elevating the sinus membrane through a crestal approach (CA) or lateral approach (LA), ACS (AteloPlug; Bioland) was inserted, and dental implants were placed simultaneously. Changes in bone volume at 12 months were evaluated by three-dimensional (3D) analyses of cone-beam computed tomography images. Factors including age, sex, smoking status, span, number of ACSs, and perforation were assessed for associations with changes in sinus bone volume using uni- and multivariable analyses based on the generalized estimating equation. Results: =0.001). Conclusion: : Use of ACS for maxillary sinus elevation resulted in detection of new bone formation in 3D analysis. Clinicians can ensure stable amounts of bone formation by inserting an adequate number of ACSs.
