The relationship between local alveolar bone housing and size of canine in maxillary canine-lateral incisor transposition: A retrospective cone-beam computed tomography-based study.

Introduction: This study aimed to use 3-dimensional data to analyze the relationship between local alveolar bone housing and canine size in maxillary canine-lateral incisor transposition.

Methods: Cone-beam computed tomography study data from 31 patients with maxillary canine-lateral incisor transposition were imported into Dolphin Imaging software (version 11.8; Dolphin Imaging and Management Solutions, Chatsworth, Calif) for measurement.

The differences of root morphology and root length between different types of impacted maxillary central incisors: A retrospective cone-beam computed tomography study.

Introduction: The purpose of this trial was to use 3-dimensional data to analyze the differences of root morphology and root length between 3 different types of impacted maxillary central incisors.

Methods: Cone-beam computed tomography images of 126 patients with impacted maxillary central incisors were included in this retrospective study. On the basis of the angle of the impacted incisor to the palatal plane, we categorized the tooth as labial inversely impacted, labially positioned, or palatal impacted incisor.

Association between palatally displaced maxillary central incisors and lateral incisors: A retrospective cone-beam computed tomographic study.

Introduction: The objective of this study was to investigate the location, orientation and root development of maxillary lateral incisors in patients with palatally impacted central incisors. Comparison was made between the lateral incisor on the affected side and that on the normally erupted side.

Methods: Cone-beam computed tomographic images from 20 patients (10 boys, 10 girls, mean age (9.

Factors affecting treatment duration of labial inversely impacted maxillary central incisors.

Introduction: A labial inversely impacted maxillary central incisor is a relatively rare occurrence. The crown of the tooth is directed upward, and its palatal aspect is facing labially. This typical orientation can be the result of trauma to the deciduous incisor transmitted to the palatal side of the crown of the permanent incisor.

Impact of fixed orthodontic appliance or clear-aligner on daily performance, in adult patients with moderate need for treatment.

Objective: To assess the impact of wearing fixed orthodontic appliance (FOA) or clear-aligner, on daily performance in adult patients.

Methods: The Oral Impacts on Daily Performance (OIDP) index was assessed in 152 adults aged 25-35 years at baseline (T0), 6 months after bonding (T1), and 12 months after bonding (T2). Participants were randomly divided into two groups: CA group (participants treated with clear-aligner) and a control group (FOA group; participants treated with FOA).
