Objective: To assess the accuracy of three-dimensional (3D) printed one-piece vs. multiple segmented transfer trays for indirect bonding techniques in moderate and severe crowding cases.
Methods: Eighty digital maxillary dental models were produced by an extraoral scanner.
Article Synopsis
- - The study aimed to analyze the pharyngeal airway dimensions of Emirati individuals based on different skeletal patterns, using CBCT scans from 103 adult subjects classified into Class I, II, and III skeletal groups.
- - Findings indicated significant associations between airway measurements and facial metrics, with correlations observed between volumes of the nasal cavity, nasopharynx, oropharynx, and hypopharynx, as well as between these volumes and anterior facial height.
- - Notably, skeletal Class I exhibited a larger nasopharynx volume compared to Class II and III, while other airway parameters showed no significant differences; the study concluded that various airway parameters correlated with anterior facial height across the different skeletal patterns.
Aim And Background: The Hall technique preformed metal crowns (HT-PMCs) are allegedly oversized, temporarily altering inter-arch relationships. Intra-arch dimensions and leeway space (LWS) HT effects are unknown.
Aim: To study single HT-PMC intra-arch effects and treated tooth dimensional changes.
Background: Desirable molar distalization by bodily movement is challenging and can be difficult to achieve. This study investigated changes in molar angulation (mesiodistal tipping), molar inclination (buccolingual torque) and rotation during distalization using clear aligner therapy (CAT).
Materials And Methods: This retrospective study included 38 cone beam computed tomographic images (CBCTs) taken for patients treated with molar distalization using CAT.
Objectives: To use the finite element method (FEM) to investigate the effect of various attachment configurations and trimming line designs of orthodontic aligners on their biomechanical performance.
Method: A 3D upper jaw model was imported into 3D design software. The upper right central incisor tooth (Tooth 11) was made mobile, and its periodontal ligament (PDL) and bone structures were designed.
