Orthodontic digital workflow: devices and clinical applications.

Introduction: The digital technology has contributed to improve and simplify diagnosis, treatment planning and execution in Orthodontics. Among CAD/CAM system (Computer-Aided Design / Computer-Aided Manufacturing) applications in Orthodontics, we highlight the installation and removal of fixed appliance, clear aligners, customized appliances, and retainers fabricated in digital environment. This approach has several advantages for practitioner and patient, as it enhances appliances precision, directly interferes in treatment time and predictability.

Linear measurement accuracy of CBCT panoramic reconstructions: experimental study with dry human mandibles.

Introduction: Studies on software accuracy of reformatted panoramic computed tomography (CT) images are scarce.

Objectives: The aim of this study was to evaluate the software accuracy of reformatted panoramic views from cone-beam computed tomography (CBCT).

Methods: Ten dry mandibles were scanned using CBCT with different voxel sizes.

Accuracy of the measurements from multiplanar and sagittal reconstructions of CBCT.

Objectives: The purpose of this study was to assess the accuracy of linear measurements performed in multiplanar reconstructions (MPR) and sagittal reconstructions (SR) of the left hemiface obtained from cone-beam computed tomography (CBCT) with 3D Dolphin Imaging software by comparing them with the same measurements made on lateral cephalograms and on dry skulls.

Setting And Sample Population: Lateral cephalograms and CBCT (with voxels of 0.25, 0.

Evaluation of the maxillomandibular positioning in subjects with sickle-cell disease through 2- and 3-dimensional cephalometric analyses: A retrospective study.

Sickle-cell disease (SCD), which involves morphological changes to the red blood cells, is the most common hemoglobinopathy worldwide. This conformational change in erythrocytes affects multiple organs and systems, including the hard and soft tissues of the stomatognathic system. The objective of this study was to provide a description of the maxillomandibular positioning of patients using computed tomography in a case series of 40 patients with SCD.

Evaluation of upper airways after bimaxillary orthognathic surgery in patients with skeletal Class III pattern using cone-beam computed tomography.

Introduction: It has been suggested that mandibular setback surgery, combined or not with maxillary advancement as a treatment alternative for patients with mandibular prognathism, can induce changes in upper airway space (UAS). Therefore, this study aimed to assess the response of the upper airway in the oropharynx region of patients with Class III skeletal pattern that underwent bimaxillary orthognathic surgery (maxillary advancement and mandibular setback) combined with mentoplasty.

Material And Methods: The sample comprised 26 cone-beam computed tomography (CBCT) scans of 13 patients.
