Effectiveness of prefabricated myofunctional appliances on Vertical Dimension in Children: A Systematic Review and Meta-Analysis

Prefabricated myofunctional appliances (PMAs) are widely adopted for correcting the sagittal and vertical dimensions during mixed dentition. Despite the effectiveness of the antero-posterior relationship has been recently evaluated, the effectiveness in correcting the vertical dimension is still uncertain. This systematic review aimed to assess the effectiveness of PMAs treatment in children with mixed dentition on the vertical dimension, including sagittal and transverse parameters that may affect the vertical dimension.
