人造听小骨有金属、塑料及陶瓷3种。金属的原子或分子受机体作用可缓缓解离。塑料中硅、特氟隆及聚乙烯较稳定且特氟隆、涤纶及硅则刺激性较小,但都不能与机体结合而无生物活性(bioactive)。陶瓷如矾土陶瓷虽对机体有亲合性但也不能与机体结合,而磷灰石陶瓷则可与机体在生物化学上结合为一体, Artificial small bones have metal, plastic and ceramic 3 kinds. Metal atoms or molecules by the role of the body can be slowly dissociated. Plastic silicon, Teflon and polyethylene more stable and Teflon, polyester and silicon are less irritating, but not with the body without bioactive (bioactive). Ceramic, such as bauxite ceramic although affinity to the body but can not be combined with the body, and apatite ceramics can be biochemically combined with the body as a whole,
