Canine-lateral incisor transposition: Controlling root resorption with a bone-anchored T-loop retraction

Abstract

Introduction: A 12-yr old female presented with a Class II division 1 malocclusion, complicated

Morphological Characteristics of the Cranial Base of Early Angle's Class II Division 1 Malocclusion in Permanent Teeth

“…There still has been lack of systematic study on effects of morphological characteristics of sagittal and vertical cranial base on the formation and development of Angle's class II division 1 malocclusion (Hsu et al, 2016;Nilsson et al, 2016;Shirazi et al, 2016). Thus, this study selected lateral radiographs of the skull of 80 patients at the age of 12 to 14 years (early permanent dentition), with an equal number of males and females.…”

Treatment of maxillary canine transposition

“…Two types of anchorage were used-TADs and a transpalatal arch-and both helped control the side effects of the mechanics used. 33,34 First, it was necessary to create space so that the canine crown could clear the lateral incisor root. In order to bodily retract the lateral incisors, a lingual button with a wire extension was bonded on the lingual surface, and a force was applied closer to the center of resistance.…”

Orthodontic management of a complete and an incomplete maxillary canine-first premolar transposition

“…At present, skeletal anchorage can be employed to simplify the use of auxiliary appliances. 27,28 For image diagnosis, CBCT allows for more accurate 3D location of the teeth involved than conventional radiographs, which helps in the decision of the most appropriate biomechanics required to solve each transposition. 26 In this patient, CBCT was available at the start and end of treatment.…”
