Aim: This in vitro study investigates the limit of expansion forces and torque wrench forces developed by five skeletal bone expander designs (MICRO 2/4 expanders™) for clinical application.
Material And Methods: A total of 30 skeletal expanders were placed in artificial bone blocks and mechanically tested, simulating maxillary expansion. Differences in jackscrew (Dentaurum™ [D], Superscrew™ [S] and Powerscrew™ [P]), number of orthodontic mini-implants (OMIs; two or four) and their placement inclinations (parallel 0° or 10° inclination) form five designs (D4/10°, S4/0°, S4/10°, P4/10° and P2/10°).
Background: Prolonged treatment times are the main reason capable of affecting patient compliance with orthodontic treatment.
Objectives: A systematic review was made to determine whether the local administration of hormones and growth factors effectively enhances orthodontic tooth movement, and to identify possible adverse effects in animal studies.
Materials And Methods: Five databases (PubMed, Scopus, EMBASE, Web of Science and Cochrane Library) were checked for experimental studies reporting one of the following outcomes: orthodontic tooth movement, histological outcomes and side effects.
Background: To estimate whether there is skeletal and/or dental asymmetry in class II subdivision patients, between the Class II side and the Class I side using of cone beam computed tomography (CBCT).
Material And Methods: A sample of 30 patients, from a private clinic, retrospectively selected; with a class II subdivision diagnosis requiring treatment, who underwent wide-field CBCT that met the inclusion criteria. The data was processed with Dolphin 3D version 11.
Objectives: To validate the effectiveness of the original standards of True Vertical (TV) Subnasal Line in orthognatic surgery planning. The present study evaluates the changes occurring in patients with skeletal Class II alterations programmed for orthognathic surgery with a view to improving their facial profile.
Study Design: [corrected] We showed a series of black profiles (composed by a first control group of subjects with normal occlusion, and another two additional groups comprised patients before -Group 2- and after orthognatic surgical correction of Class II malocclusion -Group 3-) for three groups of observers (orthodontists, surgeons and laypeople).
Introduction: The recent interest in sleep-related breathing disorders has re-opened the old debate as to whether there is a causal relationship between upper respiratory obstruction and abnormalities in dentofacial development.
Objective: To establish the impact of dentofacial development on sleep-related breathing disorders in children.
Method: This is a prospective study in which the dentofacial studies of 30 children, diagnosed with a sleep-related breathing disorder using polysomnography, were compared with a control group of 30 healthy children.
