Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: tooth borne hyrax expander group
patients of this group will receive a tooth borne hyrax expander anchored to the first premolars and first permanent molars .
|
ready made four stainless steel bands will be supported on the first premolars and first permanent molars and to which the palatal expander will be soldered to form the Hyrax,.The appliance will be activated one quarter turn per day untill reaching maximum amount of lateral expansion of the jack screw.
the patients will be recalled twice per week to evaluate the progress of treatment.

Experimental: tooth borne hyrax expander with microosteoperforation
patients of this group will receive a tooth borne hyrax expander anchored to the first premolars and first permanent molars and microosteoperforation .
|
ready made four stainless steel bands supported on the first premolars and first permanent molars and to which the palatal expander will be soldered to form the Hyrax.No activation will be provided to the hyrax expander before the micro-osteoperforation is performed. Microosteoperforation will applied bilaterally on the buccal surface between the roots of teeth at the level of mucoginival junction, starting from the distal of canine till the distal of the first permanent molar using a small sized surgical bur mounted on a hand piece . |
