Extracorporeal shock wave therapy (ESWT) may be helpful in the osseointegration of dental implants: A hypothesis

In recent decades, with the rapid development of dental implant technology, dental implants have been widely used in clinical practice. Various complications, including a lack of osseointegration, may occur after dental implantation. However, the occurrence of osteointegration failure after dental implantation is often complicated and unpredictable, and existing treatment methods cannot reverse osteointegration failure to achieve the optimum condition. A noninvasive, easy-to-operate, low-cost, fast-acting mechanotherapy is expected to solve this problem. Extracorporeal shock wave therapy (ESWT) is widely used to treat delayed healing, bone nonunion fractures, femoral head necrosis and other orthopedic diseases and plays a significant role in promoting bone regeneration. Studies have shown that ESWT can promote bone formation and osseointegration of titanium devices in vivo. In previous experiments, ESWT was found to regulate the activity of inflammatory cells, osteoblasts and mesenchymal stem cells. Studies have also mentioned the role of ESWT in promoting angiogenesis and bactericidal activity. Therefore, our hypothesis is that extracorporeal shock wave therapy can facilitate the realization of osteointegration by regulating the immune response, inducing regeneration of the jaw and alveolar bone, and promoting angiogenesis and bactericidal efficacy.
