This document summarizes a comparative case study of four different molar distalization appliances. It provides indications and contraindications for molar distalization and classifies appliances as removable or fixed. It then describes four case reports showing the use of extra-oral traction, a removable molar distalization splint, pendulum appliance, and Jones Jig to distalize molars between 7-8mm in 70-90 days in patients with Class I or II malocclusions. Diagnostic records and superimpositions are included to demonstrate dental changes from molar distalization.
