Short‐ and long‐term periodontal evaluation of impacted canines treated with a closed surgical–orthodontic approach

Abstract

The combined technique permitted the traction of the impacted canines to the centre of the crest, thus simulating a physiological eruption pattern. Correct alignment and good periodontal status were obtained.

Periodontal health of palatally displaced canines treated with open or closed surgical technique: A multicenter, randomized controlled trial

“…Of the few other studies that have recorded recession very little difference between the operated and unoperated canines has been reported. 15,16 In a retrospective analysis by Zasciurinskiene and colleagues 20 consisting of 32 patients who underwent surgical exposure using the Closed technique, six patients (18.8%) were found to have gingival recession, although the mean values were small and it was not clear at which site the recession was present, nor was the range of the recession quantified. The largest mean value was at the palatal aspect of the canine (0.16mm, SD 0.22), which was not significantly different to the unoperated contra-lateral canines.…”

Factors affecting the clinical approach to impacted maxillary canines: A Bayesian network analysis

“…The eruption of the tooth between the alveolar cortical plates prevents bone dehiscence and unfavorable orthodontic and esthetic consequences. 3,4 Therefore, the most appropriate treatment should simulate the physiologic eruption pattern that occurs at the center of the alveolar ridge, as some authors have suggested. [5][6][7][8] Orthodontic appliances and techniques specifically designed for this purpose have been proposed.…”

“…[5][6][7][8] Orthodontic appliances and techniques specifically designed for this purpose have been proposed. 4,[8][9][10][11][12][13][14][15] In case of persistent deciduous canines and unerupted permanent canines, the ''tunnel'' technique might be indicated to reproduce the physiologic eruption pattern of the canine. 4,13,14,16 The therapeutic approach to impacted canines is interdisciplinary, with many factors accounting for the final orthodontic and periodontal outcomes.…”

“…4,[8][9][10][11][12][13][14][15] In case of persistent deciduous canines and unerupted permanent canines, the ''tunnel'' technique might be indicated to reproduce the physiologic eruption pattern of the canine. 4,13,14,16 The therapeutic approach to impacted canines is interdisciplinary, with many factors accounting for the final orthodontic and periodontal outcomes. Pretreatment radiographic features of impacted canines-a-angle, d-distance, and sector of impaction according to Ericson and Kurol 17,18 -have been shown to be predictive factors for the durations of orthodontic traction 14 and comprehensive orthodontic treatment to reposition the impacted tooth.…”

“…20 However, the same radiographic variables had no predictive value for the final periodontal status of the impacted canines after surgical-orthodontic treatment to reposition the canine at the center of the alveolar ridge. 4,14 Most investigations evaluated the relationships between factors accounting for treatment outcomes of impacted canines with descriptive statistics or linear regression on a priori identified variables; more recent studies used multilevel statistics to study associations among factors without determining causal relationships. 4,14 Bayesian networks (BN) were introduced recently with the goals of generating hypotheses of possible causal relationships among variables and promoting further specific studies (ie, randomized clinical trials).…”
