Successful treatment of chronic myofascial pain-dysfunction syndrome by disocclusion time-reduction therapy has been shown to be effective in 1 to 3 months, with the major muscular changes occurring in the first 30 to 40 days following initial therapy. Disocclusion time reductions have been previously reported to quickly reduce or eliminate numerous symptoms of chronic myofascial pain-dysfunction syndrome. Proper modification of an existing occlusal scheme from one that contains lengthy disocc lusion time to one with short disocclusion time can be accomplsihed by implementing the method of occlusal adjustment known as immediate complete anterior guidance development. This paper describes the proper clinical occlusal adjustment methodology using a computerized device that shows the measurement and subsequent reduction of excessive disocclusion time. This directly lessens elevated contractile muscle activity, which leads to rapid muscular recovery of the involved dysfunctional muscle groups.
