Both the Millo and the adjustable Millo Pro compact model trimmers are designed to systematically trim models quickly with professional results. The benchtop units are engineered to minimize trimming dust, save time over hand trimming, minimize errors from rushed trimming with a handpiece, allow for more-standardized trimming, and reduce wear-and-tear on rotary handpieces. Conically shaped cutters produce smooth finished surfaces as well as even gradients and tapers. They also help free the arch from the plaster base without damage. Specially positioned extraction vents on the trimmers ensure a good field of vision around the model and keep the work area clean of dust. The adjustable cutter height of the Millo Pro model helps maintain control when trimming difficult anterior arches with heavily vestibular inclined teeth or pinned models.
