Titanium Body
Titanium body*. Light and very strong pure titanium is used for the body. The light handpiece reduces the burden on the hands during operations, and its enhanced hardness also improves its ability for autoclave sterilization. The biocompatible properties of titanium eliminate concern over allergies to metals.
*Titanium is used only for the exterior parts, and not for the interior.
