Development of new bone augmentation method using self-activated mesh device made by memory alloy

本文介绍了一种新型的记忆合金自激活网状物骨增量方法。我们用日本白色兔子进行了动物实验。将器械插入前额骨膜下。我们用显微CT和组织学方法评价骨形成。新生骨面积和占骨量的定量数据表明，实验组新生骨体积高于对照组。使用SMA技术进行骨膜扩张的自激活器械可避免供区发病率，似乎是一种可行的骨增量方法。

New bone augmentation method using self activated mesh device made by memory alloy (SMA) was developed. We performed an animal experiment using Japanese white rabbits. The device was inserted under the periosteum at the forehead. We evaluated bone formation using micro-CT and histological method. The quantitative data by the area and the occupation of newly formed bone indicated that the experimental group had a higher volume of new bone than the control group. The use of self-activated devices for the periosteal expansion using SMA technique may make it possible to avoid donor site morbidity, and seems to be a viable method of bone augmentation.
