Abstract Objectives To evaluate the stability of periodontal tissues 3 (T ), 6 and 12 ) months after esthetic crown lengthening (ACL) possible correlations between changes in those structures. Materials methods Twenty individuals were evaluated through clinical assessment, photography, tomography. Measurements included gingival margin (GM), length (CCL), interdental papilla height (PH) width (PW), thickness (GT), bone (BT), probing depth (PD), distance alveolar crest GM, cementoenamel junction. Nonparametric correlation statistics performed ( p < 0.05). Results CCL at T 0 was 7.42 ± 0.70 mm increased to 9.48 0.49 immediately ACL, but it decreased 8.93 0.65 . PD 0.60 from , 0.39 BT 0.20 mm, while GT 0.29 Both PW PH showed enlargement A positive moderate found CCL/T GT/T AC-GM/T BT/T few negative PD/T PH/T Conclusions ACL procedure effective. Although some rebound occurred, that not clinically important. tended reestablish its original length, partially due a migration GM during healing period. Besides, thickening supracrestal soft observed. Clinical relevance The present study centers on factors influencing lengthening, underscoring procedure’s influence esthetics biology need for careful treatment planning.
