Alayan J, et al. - The researchers designed this prospective controlled trial to compare maxillary sinus augmentation (MSA) using 2 different materials—anorganic bovine bone mineral (ABBM) + autogenous bone (AB) (control group) vs collagen-stabilized ABBM (test group) regarding complications, patient-reported outcome measures (PROMs) and volumetric analysis. Using a lateral wall approach, MSA was found to be safe and it correlated with mild to moderate pain and restrictions to daily activities for 48–72 hr. Patients’ reports of morbidity were greater with autogenous bone harvesting. Collagen-stabilized ABBM provided comparable bone volume to AB + ABBM that was sufficient for placement of implants of adequate size with no requirement for further vertical augmentation. They found a significant positive impact of engaging the surrounding sinus walls on graft volume.
