Comparative photoelastic study of dental and skeletal anchorages in the canine retraction
OBJECTIVE: Test Boards To compare dental and skeletal anchorages in mandibular canine retraction by means of a stress distribution analysis.METHODS: A photoelastic model was produced from second molar to canine, without the first premolar, and mandibular canine retraction was simulated by a rubber band tied to two types of anchorage: dental anchora
