Prevalence of Dehiscence and Fenestration on Incisors after Orthodontic Treatment in High-Angle Patients using Cone Beam Computed Tomography

Research output: Contribution to journalArticlepeer-review

Abstract

To assess the prevalence of dehiscence and fenestration based on alveolar bone height (ABH) and alveolar bone thickness (ABT) on upper and lower incisors in malocclusions with high-angleafter orthodontic treatment using Cone Beam Computed Tomography (CBCT).CBCT examinations were performed on twenty-seven skeletal malocclusion high-angle patientsat RSKGM Faculty of Dentistry, Universitas Indonesia, for post orthodontic evaluation. The subjectswere divided into 3 groups based on their malocclusions. ABH and ABT were measured on CBCTcross-sectional images of the upper and lower incisors to determine the presence of dehiscenceand fenestration at labial and lingual aspects.Dehiscence was associated the most in class II malocclusion (24.8%) and fenestration in classI (3.7%) and class II (3.7%) malocclusion. The prevalence of dehiscence that occurred in lowerincisors was higher (39.2%) compared to upper incisors (23.5%). The prevalence of fenestrationoccurred in upper incisors was higher (5.7%) compared to lower incisors (3.4%).The prevalence of dehiscence was highest in lower incisors of class II malocclusion, whereasfenestration in upper incisors of class I and II malocclusion, with labial, was the most frequentlyaffected side
