alineadors

Alineadores, also written as alineadors in some languages, are devices or systems designed to bring two or more elements into alignment with a reference. The term is used across several fields to describe tools that position parts with controlled accuracy and repeatability.

In dentistry, alineadores refer to clear-aligner systems: custom-made, removable plastic trays that progressively move teeth according to a digital treatment plan created from 3D scans. They work by applying gentle forces to teeth, and treatment typically requires wearing the aligners for most of the day. Benefits include aesthetics and ease of hygiene; limitations include proper case selection, need for patient compliance, and varying treatment times.

In manufacturing and engineering, alineadores are alignment fixtures, guides, or instruments used to position components before assembly, welding, or machining. Common implementations include dowel pins, shims, kinematic mounts, optical or laser alignment systems, and coordinate measuring machines. These tools improve dimensional accuracy, reduce setup time, and ensure repeatable production.

In metrology and surveying, alignment devices help orient instruments or reference frames to true directions or planes. Laser trackers, autocollimators, and spirit levels are examples that support high-precision tasks in aerospace, construction, and research.

The overarching goal of alineadores is to ensure correct positioning and orientation within defined tolerances. Effectiveness depends on the application's accuracy requirements, material behavior, and operator training.
