Radiographic Assessment of Deproteinized Porcine Versus Bovine Bone Mineral in Sinus Augmentation

The goal of this retrospective study is to compare the radiographic outcomes of deproteinized porcine bone mineral (DPBM) and deproteinized bovine bone mineral (DBBM) following lateral sinus floor augmentation (LSFA) with simultaneous implant placement. The main questions it aims to answer are: Does DPBM show greater graft resorption than DBBM at 6 months postoperatively? Do both materials achieve comparable bone quality and osseointegration outcomes despite differences in resorption rates? This is a retrospective, single-center cohort study. Participants included 56 patients (56 sinuses) who underwent LSFA with either DPBM (test group, n=28) or DBBM (control group, n=28) and had complete cone-beam CT scans taken preoperatively, immediately postoperatively, and at 6 months post-surgery. Radiographic parameters such as bone height, augmentation volume, and bone texture features were analyzed to evaluate graft stability and new bone formation.
