It is very uncertain whether CAD/CAM nitinol fixed (bonded) retainer changes stability: Little's Irregularity Index (lower arch) compared with conventional/analogue multistrand fixed (bonded) retainer (very low certainty).
It is very uncertain whether cervical pull headgear changes amount of crowding (lower incisor crowding) at 2 years compared with minor interceptive procedures (control) (very low certainty).
Cervical pull headgear led to higher size of the jaws (maxillary and mandibular arch length) compared with minor interceptive procedures (control); GRADE not reported.
Cervical pull headgear led to higher upper incisors to maxilla at 2 years compared with minor interceptive procedures (control); GRADE not reported.
Cervical pull headgear showed no clear difference in lower incisors to mandible at 2 years compared with minor interceptive procedures (control); GRADE not reported.
