The Use of Statically Determinate Force System in Closure of Anterior Open Bite in Adults.

Dentoalveolar and Skeletal Changes Associated With a Statically Determinate Force System in the Closure of Anterior Open Bite in Adults: A Single-arm Clinical Trial

The aim of the current study was to evaluate and quantify the cephalometric changes produced by maxillary and mandibular extrusion arches in closure of anterior open bite in non-growing patients.

Inclusion Criteria:

• Adult patients with anterior open bites more than 1 mm, permanent dentition except for the third molars which were extracted if erupted

Exclusion Criteria:

• Frankfort to mandibular plane angle > 40
• congenital craniofacial malformations or temporomandibular joint disorders,
• patients with severe gum show during smiling or increased incisal show at rest.
