Maxillary central incisor gingival papilla and zenith heights with and without periodontally accelerated osteogenic orthodontics

Abstract

Objectives: The objective of the study is to compare maxillary central incisor gingival papilla and zenith heights photogrammetically in orthodontically treatment patients with and without periodontally accelerated osteogenic orthodontics (PAOOs). Materials and Methods: Samples of 29 participants were matched for pre-treatment age and five gingival height dimensions supporting the four maxillary incisors. PAOO active orthodontic treatment time (9.29 vs. 20.47 months) and control post-treatment observation time (10.7 vs. 20.1 months) were significantly shorter (P < 0.05). Linear gingival heights were measured photogrametrically on standardized intraoral frontal photographs perpendicular to a horizontal line constructed parallel to the maxillary central incisal edges. Results: (1) The three papillae and two zenith gingival margins moved incisally as a consequence of conventional orthodontic therapy (P < 0.05) but not in PAOO therapy. (2) At least 6-month post-orthodontic treatment, PAOO gingival dimensions were longer for both central incisor zenith heights, and the interdental papilla height between maxillary central incisors was shorter. Conclusions: Based on the conditions of the study, orthodontic treatment with and without PAOO results in similar maxillary incisor papilla and zenith heights if viewed from a clinical perspective.
