What distinguishes a mandibular staple implant from a transmandibular implant (TMI)?

A mandibular staple implant is designed to be placed in the mandibular arch, accommodating immediate loading, and generally requires less bone for stabilization in comparison to a transmandibular implant (TMI). TMIs, which are often placed in more complex situations, need to engage more structural bone to achieve adequate support given their anchorage nature. The design and placement techniques of TMIs can necessitate a higher volume and quality of bone due to their configuration and the forces they encounter during functional loading.

In contrast, mandibular staple implants can be placed in areas where there may be reduced bone availability while still providing adequate support for immediate loading due to their unique configuration. This adaptability is a crucial aspect that allows for the use of mandibular staple implants in patients with varying bone adequacy, effectively distinguishing them from TMIs.
