Materials used for implanting have to meet very strict requirements. They have to be compatible with living tissues, must not have poisonous, allergic or malignant effects and must not corrode. They have to have the required flexibility, tensile strength, capacity and abrassion-proofness. They have to be well sterilizable and easy to work with. A part of the available materials is made of metal or alloy, such as titanium.

Due to its external oxide layer it is quite stable and it has a high external energy, so it is able to join with different molecules and proteins, with which the protein-structures of the bone tissue later can join. That is how osseous fixing of the implant happens. Besides the ones mentioned above, its greatest advantage is that it prevents decay of bones, which is unavoidable after loosing a tooth.
