How efficient is customized lingual orthodontics? An assessment of treatment outcome.

Objective: To assess the efficacy of lingual orthodontics by comparing setups and post-treatment casts.

Setting And Sample Population: Thirty-two consecutive patients treated with a customized lingual orthodontic appliance were included in this retrospective study.

Materials And Methods: Initial casts, post-treatment casts and setups were scanned, and the digital models produced were analysed in terms of overjet; overbite; molar and canine relationships; intercanine, interpremolar and intermolar distances; upper and lower arch lengths; midline deviation; bucco-lingual angulation of all teeth and mesio-distal angulation of anterior teeth.

Occlusal traits and longitudinal dental changes in children and adolescents with congenital or childhood onset myotonic dystrophy.

Background/objectives: This research aimed to study the malocclusions of children and adolescents with myotonic dystrophy type 1 (DM1), in respect to healthy individuals, and trace the occlusal changes that occurred in these individuals during growth.

Materials/methods: Thirty-six dental casts, from children and adolescents with DM1 living in western and southern Sweden, were compared with a control group of 50 healthy individuals. To identify potential changes in occlusal traits, 26 casts were assessed and followed-up over a median time of 9 years.

Craniofacial morphology and growth in young patients with congenital or childhood onset myotonic dystrophy.

Background/objectives: This study investigated the craniofacial morphology of young individuals with congenital or childhood onset myotonic dystrophy type 1 (DM1) compared to healthy subjects. The study also followed growth changes in their facial morphology over a 5-year period.

Materials/methods: Lateral cephalograms of the 26 subjects (young patients with DM1 from west and south Sweden) were taken at baseline and after a 5-year period.
