Block Autografts for Localized Ridge Augmentation

Surgical Success of Intraoral Autogenous Block Onlay Bone Grafting for Alveolar Ridge Augmentation

“…All grafting procedures and dental implantations were performed by one oral and maxillofacial surgeon (DSA) using the same operational protocol. 4,5,23- 26 Preoperatively, periapical, panoramic and conventional or computed tomography (CT) scans were evaluated for bone shape (mesiodistal width and vertical distance from vital structures: maxillary sinus, nasal cavity and mandibular canal) and bone angulation.…”

Bone Replacement Materials and Techniques Used for Achieving Vertical Alveolar Bone Augmentation

“…This may be due to low cortical to trabecular ratio in the graft, memory of endochondral vs. intramembranous ossification and different osteoblast mechano-sensing memory between donor and recipient sites. Less common extraoral donor sites for block grafts used in ridge augmentation include the tibia and cranial vault [108,109]. The use of such autologous grafts is not common in practice mainly due the aforementioned disadvantages and the high morbidity associated with the donor site.…”

Bone Augmented With Allograft Onlays for Implant Placement Could Be Comparable With Native Bone

“…This was expected because onlay bone augmentation allows the placement of longer and wider implants in deficient alveolar ridges. [13][14][15] In addition, the analysis showed that implants placed in bone augmented with allograft onlays were even longer than those placed in bone augmented with autograft onlays. This is probably because of the vertical bone resorption that occurs in autograft onlays during the first year after onlay placement, 68 although further clinical studies are needed to investigate the difference of onlay graft resorption between autograft and allograft onlays.…”
