More than half of all dental implant cases require bone augmentation procedures of various extent. Conventional procedures are frequently aggressive, less comfortable for the patient, and require a longer duration of surgery, which might have an impact on the healing process and treatment success. 3D printed bone scaffold could help to avoid these problems.
3D printing is a technology that has been modified for use in bone tissue engineering to build highly porous scaffolds. Because of the laydown pattern, this method is simple and low-cost, and it gives good mechanical characteristics and highly controllable porosity. As a result, it can be employed in a variety of applications. A 3D composite scaffold is one of the most advanced alternatives to bone substitutes since it allows cells to manage their microenvironment, proliferate, and migrate during the formation of new bone. Various organic and inorganic biomaterials may be combined or used alone to create an appropriate bone scaffold. These osteoconductive scaffolds can be modified using a variety of cell- or growth factor-based tissue engineering approaches to stimulate osteogenesis and to provide osteoinductive properties.
