About

six months follow-up of two and four mini-screw supported hyrax for maxillary expansion in non-growing patients: A randomized controlled clinical trial

Full description

transverse malocclusion is very common in adult ,using conventional hyrax expander has many limitations and side effects such as buccal tipping, marginal bone loss, dento aloveolar expansion.

in such cases , surgically assisted rapid palatal expansion used to be the option of choice ,due to the invasiveness of the procedure and co-morbidity associated with it ,minis crews assisted rapid expansion is recently introduced to overcome the complications of both convectional and surgically assisted rapid palatal expansion
