A new custom designed cleft lip and palate implant based on MARP

摘要

Something about 1 million skeletal defects are reported each year, which are in need of bone-grafting to be cured. Note that population of the world is getting older and so the probability of bone fractures is increasing, while dealing with this would have lots of social and economical effects. Bone grafts can be both autologous and autogenous or as an alternative, be made of nonorganic materials such as metals, polymers, ceramics or composite materials. Maxillofacial problems can cause a variety of malfunctions and abnormalities in the body and to handle these defects, two solutions exist, including surgical approach and non-surgical approach. In the first method, one should wait until the end of bone growth ages, and for the second, due to the need of wearing prosthesis, modifications of the prosthesis is essential as child grows. In this research a patient with cleft lip and palate was chosen and an appropriate implant was designed for him. An AFM analysis was performed to make see the stress distribution pattern. Final results show that using this method can help both patients and surgeons by improving implant-tissue contact.
