Trephine Burs

26-1Trephine Burs do not have blade at center , thus it will be rather difficult to get smooth cutting for a start . Enough exercise is recommended before use .
After Trephine Burs penetrate into bone , then smooth cutting is available . To avoid choking on bone inside  Trephine Bur , pull of Trephine Burs up and down , so that bone will always remain at patient . Remained bone can be collected by surgical curettes . Enough cooling and possibly low speed is recommended to avoid heat damage against bone .
