Comprehensive treatment approach for bilateral cleft lip and palate in an adult with premaxillary osteotomy, tooth autotransplantation, and 2-jaw surgery
We report the successful treatment of a woman aged 25 years 3 months with bilateral cleft lip and palate. She had a protruded premaxilla, collapsed posterior segments, wide alveolar defects with oronasal…
Influence of bone architecture on the primary stability of different mini-implant designs
Introduction Mechanical interlocking between a mini-implant (MI) and the bone substrate reflects directly on the primary stability achieved. The purposes of this study were to evaluate MI design performance in…
Influence of temporomandibular joint disc displacement on craniocervical posture and hyoid bone position

Cone-beam computed tomography evaluation of dentoskeletal changes after asymmetric rapid maxillary expansion
Introduction The aims of this study were to quantitatively evaluate the changes in arch widths and buccolingual inclinations of the posterior teeth after asymmetric rapid maxillary expansion (ARME) and to…
Evaluation of stress changes in the mandible with a fixed functional appliance: A finite element study
Introduction The aim of this study was to evaluate the effects of a fixed functional appliance (Forsus Fatigue Resistant Device; 3M Unitek, Monrovia, Calif) on the mandible with 3-dimensional finite…
Bisphenol A release from orthodontic adhesives and its correlation with the degree of conversion
Introduction Our objective was to quantitatively assess and compare the bisphenol A (BPA) released from an orthodontic adhesive using a light-emitting diode device (LED) or a halogen light-curing unit (HLC)…
