Periodontal Status of Patients Treated With PAO Tec Clinical Trial
Periodontally accelerated orthodontics, also known as PAO, is a novel technique combining
alveolar corticotomy and bone grafting prior to commencing orthodontic treatment. Using this
technique orthodontic de-crowding and space closing, can be completed in 60-70% less active
orthodontic treatment time. The addition of particulated bone graft following decortication
allows for the widening of the bucco-lingual alveolar bony dimension, thus creating space
for the movement of teeth, without the creation of dehiscences, usually a negative sequel of
the standard orthodontic treatment.
Aim: To evaluate the use of the PAO technique for the treatment of 20 adult patients 1 year
post orthodontic treatment.
Methods: 20 periodontally healthy adult patients requiring orthodontic treatment were
admitted in the departments of Periodontics and Orthodontics in Hadassah Medical Center. All
patients underwent full orthodontic and periodontal examination upon admission including a
pretreatment CBCT scan. Decortication followed by grafting was made after the orthodontic
appliances have been placed. The orthodontic appliances were activated immediately after
surgery and every 2 weeks. During the 1 year follow up a periodontal and orthodontic
clinical evaluation were made, as well as a CBCT scan.
20 patients were periodontally and orthodontically examined. including: full chart:ppd, free
gin line, bleeding on probing, plaque score, teeth mobility. cephalometric analysis,
clinical photographes, full periapical x rays.
perio=ortho treatment plan was scheduled, a periodontal surgery for the decortication of
buccal bone and bone grafting was preformed.
at the same day orthodontic appliances were activated. in the follow up exam a full
periodontal exam will be made (as at the beginning).
the patient will be referred to CBCT scan. all dicom files will be uploaded to simplant
software, and measurements will be made: buccal bone width from crest to apex. distance from
CEJ to crest. presence of root dehiscence and fenestrations. root resorption.
