Outcome Measures

Primary Outcomes (2)

  • Evaluation of dental changes

    3D Evaluation of the dental changes associated with an eight unit extended maxillary fixed retainer by superimposition of STL files before bonding and 6 months after bonding fixed retainer which is bonded directly after completion of active orthodontic phase, the changes in teeth position will be assessed by linear differences between the first stl and final stl file after superimposing them using medit software , on demand software ,creating linear measurement that calculate how teeth moved in antroposterior plane , transverse and vertical planes

    6 months follow up

  • lateral cephalometric changes assessment

    evaluation of the changes of axial inclination of upper incisors before bonding fixed retainer and 6 months after bonding the retainer through measuring the axial inclination changes of upper incisors(u1-sn angle( upper 1 relation to cranial base ) , interincisal angle( angle between upper and lower incisors ) ,u1- FH angle( angle between upper incisor and Frankfort horizontal plane ) ,u1 to palatal plane angle (angle between upper incisor to palatal plane ), u1 to occlusal plane(angle between upper incisor and occlusal plane )

    6months follow up

Secondary Outcomes (4)

  • PDL response through probing depth assessment

    6 months follow up

  • Gingival bleeding assessment

    6 months follow up

  • Plaque assessment

    6 months follow up

  • Gingival assessment

    6 months follow up

Other Outcomes (1)

  • Quality of life assessment

    6 months follow up

Study Arms (1)

Fixed retainer group

EXPERIMENTAL

test group who undergoes retention using extended maxillary fixed retainer

Device: Extended maxillary fixed retainer

Interventions

Bonding extended maxillary fixed retainer from right first maxillary premolar to left maxillary first premolar for 6 months then assessment of relapse using 3D superimposition , little index , lateral cephalometric assessment along with PDL assessment with quality of life ,function and speech assessment
