[Individualized clinical evaluation of tooth movement. Treatment of Class II: molar splints and structural effects]

The presentation of a synoptic chart allowing a dental arch analysis and Class II correction strategy is presented and followed by a study on 30 patients in mixed dentition and 37 growing patients in permanent dentition. These patients presenting a Class II malocclusion have been treated by Class II mechanics and lower molar individualised splint enhancing the vertical lower face height and skeletal Class II correction. This study shows a good vertical stabilization of the facial planes during the treatment, a significant growth of the lower face but it is noticed a posterior rotation of the occlusal plane in the mixed dentition sample.
