The sheet summarizes the results of a study, in which 17 patients with partially or completely edentulous jaws underwent the placement of a prosthetic implant 6 months after maxillary sinus lift surgery via the lateral approach. Patients had residual bone thickness ≤ 3 mm. The interventions involved the use of granular bone substitutes of equine origin (Bio-Gen Mix, Bioteck) and an equine collagen membrane (Biocollagen, Bioteck). During the operations, bone samples were collected for each patient for histological and histomorphometric examination. The results revealed the prevalence of newly formed bone tissue, which was in direct contact with the residual biomaterial, confirming its biocompatibility, also demonstrated by the lack of inflammatory reactions.
