Abstract
Orthodontics combined with selective alveolar decortication combined with augmentation grafting (PAOO [TM]) is 3 to 4 times more rapid with active orthodontic treatment time averaging about 6 months [1]. Treatment outcomes have been shown to be more stable [3] have a faster treatment time, and have less apical root resorption. [4] However the impact of the therapy on the periodontal health, most specifically the keratinized tissue, has not been investigated.
Objectives: To evaluate the effects of PAOO [TM] therapy on levels of keratinized tissue.
Methods: Study casts and intraoral photographs of 60 patients who underwent bi-maxillary PAOO [TM] were evaluated. Clinical photos were digitally scanned and the images increased to near life-size. Using Image J measuring software, keratinized tissue levels were measured from the life-size clinical photographs at pre-treatment, post treatment and at least 2 year retention (T1, T2, T3). Crown lengths were measured from both photographs and study casts and the ratio of photo-to-cast was used to compute a normalized keratinized tissue height.
