Synthetic Bone Graft
Manufactured bone substitutes support regeneration in procedures such as sinus-floor augmentation and are compared with other graft materials.
[6]The short answer
A synthetic bone graft is a manufactured bone substitute used to support bone regeneration in procedures such as sinus-floor augmentation. The term refers to the graft material's source, while the clinical question is how it performs in the reconstruction being carried out.

What is a synthetic bone graft?
What properties matter?
Synthetic biomaterials studied for bone regeneration include biphasic calcium phosphate, beta-tricalcium phosphate, nanocrystalline hydroxyapatite, and bioactive glass. The review literature also examines bone-volume preservation, residual biomaterial, implant stability, histological integration, and implant survival.
[6]Where might it be used?
What alternatives may be discussed?
Synthetic substitutes are compared with autogenous bone and xenografts. In the reviewed sinus-augmentation studies, implant outcomes did not differ significantly from xenograft outcomes, while less new bone formed than with autogenous bone.
[6]What does this mean for a patient?
The material is intended to preserve or build bone where implant or prosthetic rehabilitation needs support. Studies measure bone volume, residual material, implant stability, histological integration, and implant survival. These measures separate the graft's role in the healing site from the later result of the implant restoration.
[1][3][4][5][6]What risks should be discussed?
Reported results for synthetic substitutes included high implant stability, limited marginal bone loss around implants, and few complications. Study methods and outcomes were heterogeneous, so these results describe studied procedures rather than every graft operation. The evidence also compares residual graft, newly formed bone, and non-mineralized tissue, which helps explain why graft categories cannot be judged by a single outcome.
