Abutments are structural components used to support bridges, arch structures, and retaining walls by transferring loads to the ground. They are typically placed at the ends of a bridge span or at the base of an arch to provide stability and resist lateral forces. In dental applications, abutments serve as connectors between dental implants and prosthetic devices, ensuring proper alignment and support for crowns or dentures. Overall, abutments play a crucial role in enhancing the strength and stability of various structures and devices.

A structure for resisting the pressure of water against a bridge. It supports or receives the thrust of part of the arch of the bridge. It absorbs the tensions. It receives the arch at the end of a brdge
An arch bridge. I think that may have been discovered quite some time ago !!! +++ It was - the Romans used arches extensively, in buildings as a well as for bridges. However, the arch is indeed stronger than the plank, or simple beam, bridge because it transmits the loads to its abutments. You can stiffen a beam bridge by fitting it with vertical side-members, or in larger structures, frames (trusses).

In an arch bridge, the weight is distributed along the curve of the arch, transferring loads to the supports at each end. The arch shape allows the forces from the weight of the bridge and any additional loads (like traffic) to be converted into compressive forces that push outward and downward. This distribution minimizes tension, making the structure stable and efficient in handling both static and dynamic loads. The design effectively directs stresses to the ground through the abutments, ensuring stability.
That is the correct spelling of the plural noun "abutments."

For a fixed partial denture (FPD) replacing all maxillary incisors, the ideal abutments would typically include the canines and possibly the first premolars, provided they have sufficient periodontal support and are free from significant restorations or pathologies. These teeth should be adequately prepared to distribute occlusal forces evenly and provide stability for the prosthesis. Additionally, careful consideration of the angulation, tooth structure, and esthetics is essential when selecting and preparing the abutments.

An arch bridge is a bridge with abutments at each end shaped as a curved arch. Arch bridges work by transferring the weight of the bridge and its loads partially into a horizontal thrust restrained by the abutments at either side. A viaduct (a long bridge) may be made from a series of arches, although other more economical structures are typically used today.

Abutments are supporting structures that bear the load of a bridge or similar construction at the points where it meets the ground or other structures. They transfer the weight of the structure and any loads placed on it to the ground below, helping to stabilize and distribute the forces involved.
