Electret method of promoting callus formation in regeneration of bones

摘要

Disclosed is an electret for use in regeneration of bones which is essentially made of polytetrafluoroethylene (Teflon), polyhexafluoropropylene (FEP Teflon), polyester (Mylar), polypropylene and other substances having high molecular weight, or carnauba wax, bees wax, rosin and other waxy or resinous substances having lower molecular weight. The electret according to this invention when applied to broken bones will expedite the callus formation on bones.
