The effect of bite planes on deepbite correction with clear aligners.

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
objectivesDeep overbite correction with clear aligners faces challenges including decreased anterior intrusion efficiency and spontaneous molar intrusion. Bite planes are often incorporated to address these issues, but their effects remain debated. This study aimed to investigate the impact of bite planes on anterior intrusion efficiency and posterior displacement during a specific deep overbite correction phase using clear aligners. MATERIALS AND
methodsThis retrospective study included 36 adult patients with deep overbite who were treated with the clear aligner (Smartee
resultsNo significant difference was found in anterior intrusion accuracy between the bite plane group (18.8% ± 24.7%) and the control group (18.4% ± 21.6%). The bucco-lingual movement of teeth where bite planes were designed was not significantly affected. Premolars in both groups exhibited extrusion ranging from 0.0 to 0.5 mm, with no significant intergroup difference. Molars in the control group exhibited 0.1-0.2 mm of spontaneous intrusion (P<0.01), which showed a positive correlation with treatment duration. The maxillary molar intrusion correlated moderately with the number of aligners (r = 0.49, P<0.0001), while the correlation was weaker in the mandible (r = 0.33, P = 0.0031). In contrast, the bite plane group showed no spontaneous molar intrusion but rather slight extrusion of 0.1-0.2 mm, with no correlation with treatment duration.
conclusionBite planes in clear aligners do not enhance anterior intrusion efficiency or affect labiolingual movement but effectively prevent spontaneous molar intrusion caused by the "posterior bite-block effect," thereby helping maintain vertical molar position during deep overbite correction. CLINICAL RELEVANCE: The bite planes in clear aligners are less effective in inducing posterior teeth extrusion and the associated increase in vertical facial height compared to those in fixed appliances. However, they do not affect the intrusion and labiolingual movement of anterior teeth, and prevent spontaneous intrusion of molars, making them a recommended design for deepbite correction in both normodivergent and hypodivergent patients.
