Transosteal
Explanation:
One of the ways to get a missing or broken tooth fixed is through dental implants. It can also be used to fix loose teeth. For this to occur, a tooth root is needed to hold in place the dental prosthesis.

This surgical implant, which now serves as a tooth root, enables the dentist to fix a replacement tooth.
<em>Transosteal implant</em> is a type of dental implant in which the surgical component is a U-shaped metal frame or pins that is inserted into the lower jaw followed by the replacement tooth on top during tooth replacement.
