Histological analysis of the use of biphasic ceramics based on hydroxyapatite and β-tricalcium phosphate in maxillary sinus floor elevation surgery: pilot study

“…The group of alloplastic biomaterials has been very indicated among the biomaterials as an alternative to the use of autogenous bone due to its good osteoconduction property that allows the implants and maintenance of clinical results with high survival rates 9 . Biphasic ceramics based on hydroxyapatite and β-tricalcium phosphate have been widely used in a wide variety of clinical situations such as maxillary sinus elevation 10 , maintenance of post-extracting alveoli 11 and filling of defects such as dehiscences in immediate implants 12 . It has been reported that the action of this biomaterial to promote bone formation is associated with reabsorption of the β-tricalcium phosphate portion, which may induce osteoblastic differentiation, and the maintenance of hydroxyapatite, which allows the process of osteoconduction and reduction of resorption of the body of the biomaterial in comparison to alloplastic grafts constituted of pure β-tricalcium phosphate 10,13,14 .…”

Single-Tooth Morse Taper Connection Implant Placed in Grafted Site of the Anterior Maxilla: Clinical and Radiographic Evaluation

“…In these contexts and following tooth extraction, regenerative techniques have been recommended to allow for ridge augmentation, which improves soft and hard tissue volume for the implant placement [ 11 , 12 ]. Over the years, a number of ridge reconstruction techniques have been proposed, such as buccolingual expansion with osteotomes, screws ridge-splitting techniques, augmentation with autografts, allografts, and xenografts, as well as guided bone regeneration (GBR) [ 11 – 13 ]. The surgical technique of GBR is a method for achieving bone regeneration by creating a secluded anatomic site using barrier membranes, with or without a biomaterial scaffold, to promote healing [ 11 , 13 , 14 ].…”

GBR technique uses different types of membranes to maintain the space and to protect the blood clot formed in the bony defect (such as socket voids created by extractions).…”

“…GBR technique uses different types of membranes to maintain the space and to protect the blood clot formed in the bony defect (such as socket voids created by extractions). With these devices it is possible to prevent the migration of the undesired epithelial cells and connective tissue fibroblasts from the adjacent tissue into the defects [ 13 , 14 ]. As a consequence, osteogenic cell populations from the native bone are prompted to stimulate new bone formation in the bone defect [ 13 , 14 ].…”

Various grafting materials have been used to fill the gap and to promote bone healing in GBR [ 11 – 14 ].…”
