The elapsed time in seconds, measured from the beginning of an excursive movement that is commenced with all teeth in complete intercuspation, and is made in one direction through until only canines or incisors are in contact. The Disclusion Time can be measured in three different excursive movements; the Right Excursion, the Left Excursion, and the Protrusive Excursion. In the Force vs Time Graph, the Disclusion Time is quantified within the C-D period. < 0.4 seconds from excursive commencement until posterior disclusion is considered as immediate, and is desirable physiologically.

Abstract
The newly designed T-Scan 10 Computerized Occlusal Analysis system represents the state of the art in occlusal diagnosis. The reliability of the system's high definition recording sensors, the many occlusal analysis timing and force software features, and the modern-day computer hardware electronics that record occlusal function in 0.003 second real-time increments, affords a clinician unparalleled occlusal contact timing and force information, with which to predictably diagnose and treat many occlusal abnormalities. T-Scan 10 represents the culmination of 34 years of T-Scan technology innovation development. T-Scan 10 has revised desktop graphics with additional toolbar buttons that enhance T-Scan functionality and improve chairside T-Scan clinical implementation. The system's most recent important advancement, discussed in this chapter, is the melding of T-Scan digital occlusal force and timing data with digitally-scanned dental arches to overlay T-Scan data on a patient's virtual arch. This is a major system upgrade that inserts the T-Scan technology directly into the digital dentistry revolution presently arising in dental medicine. The chapter details the five useful diagnostic occlusal recordings employed when treating commonly observed occlusal problems, and lastly outlines the three learning levels of T-Scan mastery that must be accomplished for a clinician to become an effective and competent T-Scan user.
