“…131 Frequently, NiTi SMAs are manipulated to the desired shape in vitro and then applied in vivo, e.g., as bone distractor. [132][133][134] In a recent study, a NiTi-SMA plate was heated by electromagnetic stimulation, yielding higher material stiffness, which in turn resulted in increased fixation stiffness and resulted in better bone healing in a rabbit osteotomy model. 135 Importantly, NiTi SMAs have already been used clinically, including in patients with cleft lip and palate, 136 in patients undergoing midfoot or hindfoot arthrodesis, 136 in treating adolescent idiopathic scoliosis, 137 etc.…”

On the road to smart biomaterials for bone research: definitions, concepts, advances, and outlook

The demand for biomaterials that promote the repair, replacement, or restoration of hard and soft tissues continues to grow as the population ages. Traditionally, smart biomaterials have been thought as those that respond to stimuli. However, the continuous evolution of the field warrants a fresh look at the concept of smartness of biomaterials. This review presents a redefinition of the term “Smart Biomaterial” and discusses recent advances in and applications of smart biomaterials for hard tissue restoration and regeneration. To clarify the use of the term “smart biomaterials”, we propose four degrees of smartness according to the level of interaction of the biomaterials with the bio-environment and the biological/cellular responses they elicit, defining these materials as inert, active, responsive, and autonomous. Then, we present an up-to-date survey of applications of smart biomaterials for hard tissues, based on the materials’ responses (external and internal stimuli) and their use as immune-modulatory biomaterials. Finally, we discuss the limitations and obstacles to the translation from basic research (bench) to clinical utilization that is required for the development of clinically relevant applications of these technologies.

“…Yamauchi et al [31, 32, 38] then designed a new type of self-activated memory alloy (SMA) (Figure 1(c)); it does not need distraction screws and thus solves the complications with the minimal invasion. Nonetheless, the accuracy and controllability of the above two kinds of expansion devices were relatively poor.…”

“…Lethaus et al [24] put the distraction device under the calvarial bone, the result showed that the cumulative bone mass was about 66% in dynamic group and 67% in static group, and there were no significant differences between the two groups with regard to bone quality or quantity. Yamauchi et al [38] used a SMA mesh device and an absorbable thread to conduct dynamic distraction; result showed that dynamic distraction group had higher volume of newly formed bone by comparing with simple SMA group.…”

The treatment of bone defects is challenging and controversial. As a new technology, periosteal distraction osteogenesis (PDO) uses the osteogenicity of periosteum, which creates an artificial space between the bone surface and periosteum to generate new bone by gradually expanding the periosteum with no need for corticotomy. Using the newly formed bone of PDO to treat bone defects is effective, which can not only avoid the occurrence of immune-related complications, but also solve the problem of insufficient donor. This review elucidates the availability of PDO in the aspects of mechanisms, devices, strategies, and measures. Moreover, we also focus on the future prospects of PDO and hope that PDO will be applied to the clinical treatment of bone defects in the future.

Periosteal expansion osteogenesis (PEO) results in the formation of new bone in the gap between periosteum and original bone. The purpose of this study is to evaluate the use of a polyethylene terephthalate (PET) membrane as an activation device. A dome-shaped PET membrane coated with hydroxyapatite/gelatin on the inner side was inserted between the elevated periosteum and bone at the rabbit calvaria. In the experimental group, the membrane was pushed, bent, and attached to the bone surface and fixed with a titanium screw. In control group, the membrane was only inserted and fixed with titanium screw at original shape under the periosteum. After
