简要总结
Labial alveolar bone thickness and apical root resorption changes associated with self-ligating versus conventional brackets.
The aim of this study will be to compare labial alveolar bone thickness and apical root resorption changes associated with self-ligating versus conventional brackets.
详细描述
Labial alveolar bone thickness and apical root resorption changes associated with self-ligating versus conventional brackets.
Protocol submitted in partial fulfillment for the requirements of Master Degree in Orthodontics.
The initial stage of treatment crowding permanent teeth orthodontically is worried about teeth leveling and alignment. The accuracy of this procedure depends on various variables.
Friction is generated upon the materialistic composition of different bracket and archwire types, and the technique of ligature between them.
Several self-ligating brackets have been grown since 1935. Self-ligation doesn't need for an elastomeric attachment to catch the archwire, so it is related with a highly reduced friction with many different types of archwires, therefore less force required.

结局指标
主要结局
Apical root resorption
时间窗: Change from baseline in Apical root resorption at 6 months
Apical root resorption will be measured in millimeters using CBCT by determining the difference in the total tooth length, which was measured from the incisal border to the root apex, between T0 and T1 (T1-T0).
Labial alveolar bone thickness
时间窗: Change from baseline in Labial alveolar bone thickness at 6 months
Labial alveolar bone thickness will be measured in millimeters using CBCT at the site neighboring to the widest point of the labiopalatal root in two levels separated by 3 mm (L1 and L2, respectively); these levels were set along the long axis of the incisor and located every 3 mm from the cementoenamel junction (CEJ) level. Labial alveolar bone thickness was assessed at the cervical level (L1) and midroot level (L2) at T0 and T1.
