High metallic ankylotic sound
Treatment
Open apex <3mm
Spontaneous eruption
Open Apex 3-6mm
Orthodontic repositioning
Flexible splint 2 weeks then check if there needs to be surgical (forceps) repositioning
RCT 2-3 weeks later
Completed root formation
Surgical (foreceps) repositioning
Flexible splint 4 weeks
RCT 2-3 weeks later
Endo
Necrotic pulp
Avulsion

Follow up
2 wk (R), 4 wk (R), 3 month (R), 6mnths (R), 1 yr(R) & yearly for 5 yr (R)

Poor prognosis
Gonna need to RCT
Flexible splint 4 wks
Tetracycline 2ds for 7 days
Closed apex
Tooth already re-implanted
Flexible splint 2 wks
Tetracycline 2ds for 7 days
RCT 7-10 days AFTER re-implantation & BEFORE splint removal
If you do it earlier than this then the calcium hydroxide can increase chances of ankylosis
calcium hydroxide as an intra-canal medicament for up to 1 month followed by root canal filling
EADT <60 mins
