Treatment of an impacted dilacerated maxillary central incisor

Root morphology and development of labial inversely impacted maxillary central incisors in the mixed dentition: A retrospective cone-beam computed tomography study

“…However, previous studies have suggested that successful orthodontic treatment of impacted dilacerated incisors depends on manipulation of the inherent potential of Hertwig's epithelial root sheath. 14,15 This was further confirmed by our study: labial inversely impacted maxillary central incisors should be treated as soon as possible. Although the root continues to grow, it develops in an irregular direction after inversion, resulting in increased dilaceration as dental age increases (Table III).…”

“…[13][14][15] To determine the appropriate age to begin treatment and methods for treating inversely impacted incisors, 3D data are needed to simultaneously and systematically analyze both the development and the morphology of impacted teeth. [14][15][16] Thus, the aim of this retrospective study was to comprehensively analyze root morphology and development in 41 patients with labial inversely impacted maxillary central incisors in the mixed dentition. A CBCT system was used in pretreatment analysis and diagnostic workup.…”

Evaluation of root and alveolar bone development of unilateral osseous impacted immature maxillary central incisors after the closed-eruption technique

“…[2][3][4][5] A strong positive relationship has been found between the necessary duration of this treatment and the patient's age, 1 and many researchers have reported that treatment begun in younger patients yields better results. 6 However, much of this research into the closederuption technique showed important problems that need to be solved.…”

A novel approach for treatment of the impacted maxillary incisor

“…This would have been difficult or impossible to achieve using conventional attachments, Additionally, this technique preserved the labial cortical bone as a minimal amount of clinical crown was sufficient to provide retention for the precision attachment which was replaced, when the severity and depth of impaction had reduced, with a labial bracket without the need for another surgical exposure. The second surgical exposure was avoided which might be required if a single exposure to place an initial labial bracket from the outset otherwise be undertaken (Lin, 1999;Pavlidis et al, 2011).…”
