The ATI is not a standard wax try-in, but rather an acrylic milled base with precision sockets which has been fabricated using the information taken from the initial impressions and Anatomical Measurement Device (AMD). The teeth are then set in a rim of wax that has been applied to the ridge giving the clinician the advantage of an advanced try-in with a precise base plate and occlusal scheme that is accurate and true to the records supplied.
