The effect of orthodontic extrusion on alveolar bone - a prospective clinical study

Introduction/Objective. Orthodontic extrusion is the procedure for moving teeth in a vertical, coronal direction. This movement induces changes periodontal ligament and production of new alveolar bone. The objective study was to determine on buccal, palatal interdental bone as result orthodontic extrusion. Methods. Experimental group included six patients who received treatment with fixed appliances; control four without treatment. Two cone-beam computed tomography scans (initial final) were obtained each patient both groups. Length tooth, shortest distance from tooth?s center resistance referent plane, buccal or plate tip enamel-cement junction, height septum, vertical gain, thicknesses measured initial final scan experimental group. Results. reduced length extruded tooth observed mesial interproximal septum gain significantly increased No significant difference found distal buccal/palatal thickness between Conclusion. affects level by gaining hard tissue teeth, while insignificantly changed.
