Incidence of unexpected condylar displacement following comprehensive orthodontic treatment in adults.
Article in The Angle orthodontist, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectivesTo evaluate the incidence and pattern of unexpected/excessive condylar displacement after comprehensive orthodontic treatment in adults. MATERIALS AND
methodsAdult patients (age ≥18 years) who underwent comprehensive orthodontic treatment with pre-(T1) and post-treatment (T2) cone beam computed tomography scans were consecutively collected within an orthodontic cohort (N = 291). T1 and T2 CBCTs were superimposed three-dimensionally (3D) and condylar displacement was estimated by the 3D changes of condylar neck point (CdN) between T1 and T2 (ΔCdN). Participants with excessive condylar displacement (ΔCdN >1 mm) were classified as condylar displacement (+) and otherwise as displacement (-). The incidence and pattern of condylar displacement, association with factors such as sex, age, skeletal relationship, extraction pattern, treatment duration, history of temporomandibular joint disorder, and presence of condylar resorption with the final occlusal outcome were investigated.
resultsThe incidence of unexpected condylar displacement >1 mm in the adult orthodontic cohort was 6.2%. Females (vs males; OR: 9.07; [95% CI: 1.19-69.23]) and Skeletal Class II (vs Classes I and III; OR: 4.57 [95% CI: 1.58-13.20]) demonstrated significantly higher odds of unexpected condylar displacement (P < .05). Condylar resorption was not evident in participants with condylar displacement and did not interfere with the final orthodontic outcome.
conclusionsUnexpected 3D condylar displacement exceeding 1 mm was noted in approximately 6% of the adult orthodontic patient cohort. However, the condylar displacement per se was not associated with condylar resorption and did not cause clinical concerns.
