machined surface

Syn.: Turned surface An implant surface that results from the milling process of a cylindrical titanium rod. The scratches of the tooling on the implant form a machined implant surface.


Magnesium can be used as implant material. It has metallic strength and can be bioabsorbed (converted in magnesium oxide and hydrogen, degradation, corrosion). It can be used to stabilize bone fractures. Mechanical properties are similar those of natural bone.   more details: 1.

Modulus of elasticity

Ratio of stress over strain., when the deformation is elastic. It is a measure of stiffness or flexibility of a material. A stiff material has a high modulus of elasticity and a flexible material ha s a low modulus of elasticity. Syn.: Young´s modulus



Mucosal insert

Syn.: Button implant, epithelial implant, intramucosal insert, mucosal implant. Mushroom-shaped device fastened to the tissue surface of a removable denture that fits within a prepared gingival receptor site. The use of multiple mucosal inserts enhances a denture´s retention and stability. As it does not perforate dermal/mucosal integrity, it is no real implant.
