Acceptability comparison between Hawley retainers and vacuum-formed retainers in orthodontic adult patients: a single-centre, randomized controlled trial.

Background: Hawley retainers (HRs) and vacuum formed retainers (VFRs) are the most commonly used removable retainers in the orthodontic practice. Patients' cooperation in wearing these appliances is affected by the levels of discomfort and oral impairment. The evidence regarding their acceptably among orthodontic patients is limited.

Computerized axiographic evaluation of the changes in sagittal condylar path inclination with dental and physical development.

Introduction: The aim of this study was to quantify the changes in sagittal condylar path inclination during maximum mandibular protrusion in relation to the stage of dental and physical development throughout the mixed dentition period.

Methods: A total of 161 children, 6.5 to 13 years of age, were divided by dental stage into 3 subgroups: early mixed dentition without anterior guidance, early mixed dentition with anterior guidance, and late mixed dentition.

Cleidocranial dysplasia: molecular genetic analysis and phenotypic-based description of a Middle European patient group.

Cleidocranial dysplasia (CCD) (OMIM 119600) is a rare dysplasia of osseous and dental tissue. Characteristic features are typical facial and dental appearance plus morphologic anomalies. RUNX2 (OMIM 600211), the responsible gene for CCD, is considered to be a master gene for bone development and bone homeostasis.
