A biomechanical investigation of miniscrews placed on a mandible for temporary anchorage; a patient-specific finite element analysis.

Miniscrews are temporary skeletal anchorage devices that are widely used in orthodontic treatment, and their success depends on the placement area, angle, technique, and screw dimensions. This study aimed to investigate the effects of miniscrew lengths, insertion angles, and force directions on a mandible model consisting of teeth, cortical and cancellous bones. One Dental Volumetric Tomography (DVT) scan from a patient who had miniscrews were used for mandibular bone modeling to perform finite element analysis.

Comparison of In-Person vs. Video Directly Observed Therapy (VDOT) on Stigma Levels in Tuberculosis Patients.

Introduction: To investigate the effect of video directly observed therapy (VDOT) on stigma levels in tuberculosis (TB) patients.

Methods: Thirty TB patients (36.5%) receiving directly observed therapy (DOT) and 52 receiving VDOT (63.
