Precision is of paramount importance to ensure optimal esthetic results and perfect fit of dental restorations. This precision is demonstrated by the ability to achieve extremely accurate measurements and fits throughout the design, fabrication and bonding process.Microscopes and dental magnifiers play an important role in ensuring precision when preparing teeth for veneers. The most ergonomic loupes were developed from the 1990s onwards, starting with an adjustable magnifier system through to lighter loupes. They are equipped with magnifying lenses and integrated lighting systems, enabling dentists to work with greater precision and provide superior patient care. The surgical operating microscope was introduced in the early 1920s. It offers high magnification ranging from (2x-8x) to (16x-25x) for the most powerful. This gives dentists a more detailed view.
