An **abutment** is a structure that supports the end of a bridge, arch, or dam, and which receives the thrust or weight from it. It is typically a solid mass of masonry, concrete, or other strong material. Abutments provide lateral and vertical support, transferring loads from the supported structure to the ground. They are crucial for stability and durability, ensuring that the supported structure can withstand the forces acting upon it. Furthermore, an abutment can also describe a point where two properties share a boundary or are adjacent to one another, extending the concept to a broader context of adjacency and support. Finally an abutment can refer to a specific part of a dental implant that connects to a crown.
