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

Outcomes

Primary Outcomes

Skeletal effects

To compare the amount of skeletal expansion using linear (mm)measurement extracted from cone beam computed tomography pre and post-expansion

Time frame: the outcome will be assessed immediate post expansion (one month-tow month)

Secondary Outcomes

Time frame: 1-2 months

Dento-alveolar effects

To compare the amount of Dento-alveolar expansion using angular(degree) measurement extracted from cone beam computed tomography pre and post-expansion

Time frame: 1-2 months
