Characteristics of studies

Characteristics of included studies [ordered by study ID]

Almeida 2005

Methods

Allocation concealment ‐ no; blinding of outcome measurements ‐ no; completeness of follow up ‐ yes.

Participants

60 children (43 girls and 17 boys), aged 7‐10 years old, with Angle Class I anterior open bite > 1 mm, and no tooth agenesis, lost permanent teeth, crowding, maxillary constriction or posterior crossbites.

Interventions

2 groups: intervention group with 30 children (20 girls, 10 boys) with removable appliance with palatal crib, 14‐16 hours/day, associated with high‐pull chincup used at night; versus 30 patients not treated (23 girls, 7 boys); duration: 12 months.

Outcomes

Cephalometric variables of evaluation of skeletal, dento‐alveolar and tegumentar alterations.

Notes

Randomisation process provided following correspondence.

Erbay 1995

Methods

Allocation concealment ‐ not described; blindness of outcome measurements ‐ not described; completeness of follow up ‐ yes.

Participants

40 children with Angle Class I skeletal anterior open bite, in the mixed dentition stage and not permanent teeth extracted over the study period.

Interventions

2 groups: 20 Frankel's function regulator‐4, 18 hours/day and lip‐seal training with plastic versus 20 no treatment; duration: 2 years.

Outcomes

30 cephalometric variables of sagittal and vertical effects.

B ‐ Unclear

Kiliaridis 1990

Methods

Allocation concealment ‐ not described; because of side effects, there was change of experimental design in the magnet group and the results were not statistically analysed.

Participants

20 children with skeletal anterior open bite, aged 9‐16 years old, without sucking habits recorded within recent years.

Interventions

2 groups: 10 bite‐blocks versus 10 repelling‐magnet splints; 18 hours/daily; duration: 6 months.

Outcomes

Dental casts, intraoral photographs and lateral cephalograms were taken before and after treatment and used to assess dental and skeletal changes.
