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

Study Arms (1)
Fixed retainer group
EXPERIMENTALtest group who undergoes retention using 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
Eligibility Criteria
You may qualify if:
- Patients who finished the active orthodontic treatment and started the retention phase.
- Both genders.
- Extraction and non-extraction cases
You may not qualify if:
- Patients who had active transverse palatal expansion.
- Patients with active periodontal disease.
- Patients with systemic disease and bone diseases, or craniofacial syndromes, or the presence of cleft.
- Patients with abnormal surface or morphological tooth structure or restorations.
