Predictability of anterior teeth intrusion overcorrection design and its influencing factors: deep bite correction with Invisalign.
Article in Clinical oral investigations, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
objectivesThis study aims to assess the clinical outcomes of anterior teeth intrusion overcorrection using clear aligners in deepbite patients and to investigate potential factors associated with the clinically achieved overcorrection amount. MATERIALS AND
methodsTwenty-four patients with deepbite (13-50 years, mean age 26.3 years; 17 females, 7 males) treated with Invisalign incorporating overtreatment were retrospectively reviewed. Pre- and post-treatment intraoral scans were superimposed using anatomical landmarks and aligned with ClinCheck models. Overbite reduction, and the differences between the simulated and achieved movements of individual anterior teeth were measured. Linear regression analyses were performed to identify variables potentially influencing intrusion outcomes.
resultsThe mean overbite reduction was 3.3 mm, and the overall accuracy of intrusion was 52.2%. Maxillary and mandibular incisors achieved 0.7-1.8 mm of intrusion (47.3%-55.0%), whereas the canines showed lower intrusion (0.2-0.5 mm, 23.1%-29.0%). Regression analysis suggested initial overbite, mandibular plane angle, upper incisor inclination, ANB angle and the use of Class II elastics as variables that may be associated with achieved intrusion.
conclusionsA strategically designed occlusal setup-characterized by a fusiform anterior open bite, deepened maxillary occlusal curve, and reverse curve of Spee in the mandible-may facilitate effective deep bite correction with clear aligners. CLINICAL RELEVANCE: This study presents a potentially effective and minimally invasive protocol for deepbite correction with clear aligners, drawing biomechanical inspiration from the reverse curve of Spee, commonly used in fixed orthodontics. Patient-specific anatomical and treatment-related factors appear to influence outcomes and should be taken into account in treatment planning.
