Altered passive eruption diagnosis and treatment: a cone beam computed tomography‐based reappraisal of the condition

Abstract

The CBCT can be used in the diagnosis and treatment planning of APE cases. Anatomically, the APE cases described often presented a thick facial bone plate.

Cone‐Beam Computed Tomography as a Diagnostic Method for Determination of Gingival Thickness and Distance between Gingival Margin and Bone Crest

“…In this study, the mean gingival thickness obtained using CBCT was 1.17 ± 0.26 mm for incisives and 1.08 ± 0.28 mm for canines. Similar results were registered by Batista et al [41] and La Rocca et al [43] For molars, the mean gingival thickness found in our study was 1.32 ± 0.54 mm, higher than that reported by Ueno et al [44] (1.13 ± 0.88 mm), who measured gingival thickness in human cadavers using MSCT.…”

Prevalence of Altered Passive Eruption in Orthodontically Treated and Untreated Patients

“…Batista et al 23 used cone‐beam computed tomography to diagnose and characterize the hard and soft tissue anatomic features of APE‐affected teeth. The mean soft tissue thickness (measured 2 mm apical to the gingival margin) was ≥1 mm for canines, lateral incisors, and central incisors, and all individuals with APE presented features of a thick biotype with a flat gingival architecture.…”

Crown lengthening procedures: A literature review

“…66 More recently, accurate evaluation of the distance between the CEJ and the bone crest can be performed using conebeam computed tomography. 67,68 Soft tissue cone-beam computed tomography has been reported to improve soft tissue image quality and allow the determination of the dimensions and relationships of the structures of the dentogingival unit 68 (i.e., the distance of the gingival margin to the facial bone crest, the gingival margin to the CEJ, and width of the facial gingiva).…”
