Evaluation of the clinical efficacy and safety of modified alveolar cleft bone graft with cone-beam CT digital imaging in children.

Background: Cone-beam computed tomography (CBCT) is used to observe the bone density and bone height in children with modified alveolar bone graft (ABG) at different times after operation. In this study, the changes of labial-palatal bone mass in the stable period of bone union and in the bone graft area were investigated to provide reference for subsequent treatment.

Methods: A total of 140 pediatric patients with unilateral complete alveolar cleft were selected and routinely underwent iliac bone grafting.

[Three-dimensional localization and assessment of maxillary palatal impacted canines with cone-beam computed tomography].

Purpose: To evaluate the location of maxillary palatal impacted canines and resorption of neighboring incisors with cone-beam computed tomography (CBCT).

Methods: Twenty-two healthy adolescent patients who had received orthodontic treatments at Stomatological Hospital of Nanjing Medical University were selected and scanned by CBCT. Palatal impacted maxillary canines were reconstructed by Dolphin imaging 11.
