Proclination-induced changes in the labial cortical bone thickness of lower incisors

Popis výsledku v původním jazyce

OBJECTIVES: We sought to objectivize the overall alveolar bone thickness changes in lower incisors after orthodontic intervention. BACKGROUND: The effect of orthodontic treatment on the cortical bone, specifi cally the clinical implications of proclination-induced change, have long been a matter of dispute. METHODS: Cone-beam computed tomographs of 58 patients were obtained before and after treatment and labial cortical bone thickness and overall alveolus width were measured in sagittal sections in the distance of 3, 6, 9 and 12 mm apically from the cemento-enamel junction. RESULTS: A statistically signifi cant decrease of the cortical bone thickness in all four incisors was found at the levels 3, 6 and 9 mm (p &lt; 0.05), with mean differences of 0.19, 0.10 and 0.14 mm, respectively. The cortical bone thickness at the level of 12 mm and alveolar width at all the levels showed no signifi cant changes (p &gt; 0.05). Moreover, no correlation was found between bone thickness change and extent of the incisor movement. CONCLUSION: Our results point to a marked cortical bone loss after proclination of lower incisors, furnishing a sound basis for caution in treatment planning due to the considerable risk of alveolar defect development, especially in patients with low initial bone thickness (Tab. 6, Fig. 2, Ref. 25).
