Monitor mounts

Monitor mounts pivot to accommodate viewing from a variety of patient positions. Increase case acceptance when you incorporate the use of an intraoral camera with a chairside monitor.

A cabinet-mounted monitor at 12 o’clock makes an excellent choice for patient record keeping and practice management applications. Ceiling, wall, and central/side cabinet-mounted monitors are ideal for providing patient entertainment in either seated or supine positions.
