Alternatives to metal
Porcelain
Dental bone china is a objects next to corresponding properties to os solid body substance. It absorbs and reflects frothy the way our automatic teeth do. Light travels done the bone china to the soldering stuff which attaches the headband to the tooth, and later bounces vertebrae. This gives the ceramic ware headband a clear expression hugely approaching that of our natural dentition.
