Effect of Gingival Biotype on Periodontium of Maxillary Impacted Canine after Orthodontic Traction

doi:10.13701/j.cnki.kqyxyj.2023.04.014

Abstract

Abstract: Objective: To study the influence of different gingival biotypes on periodontal tissue of maxillary impacted canines after orthodontic traction. Methods: Twenty-four patients with unilateral impacted canines were divided into thin gingival biotype group and thick gingival biotype group (n=12 for each group) according to the gingival thickness of the contralateral canine. After treatment, the apical alveolar bone thickness, labial alveolar bone thickness, the loss of labial alveolar bone height, and gingival attachment width of impacted canines and control canines were measured. Results: The differences of any measurement variables between two groups were significant after the treatment (P<0.05). The differences of the labial alveolar bone thickness, the loss of labial alveolar bone height, and gingival attachment width between the impacted canines and the control canines in the thick gingival biotype group were smaller than those in the thin gingival biotype group (P<0.05). Conclusion: The thick gingival biotype is more beneficial to the reconstruction of periodontium for maxillary impacted canine after orthodontic traction.

Key words: impacted canine, gingival biotype, alveolar bone reconstruction, orthodontic traction
