Evaluation of different models of intrusive force application and temporary anchorage device (TAD) placement in total arch intrusion using clear aligners; a finite element analysis.
Article in BMC oral health, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 5 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
introductionPresent study aims to evaluate different models of total arch intrusion using clear aligners in a finite element setup, which might be helpful in gummy smile patients who seek this treatment modality.
methodsFour patterns of intrusive forces were applied on each side of the upper arch aligner model: (1) Distal to the lateral incisors (facial - 80 g) and distal to the first molar (palatal - 150 g). (2) Distal to the lateral incisors (facial - 80 g) and distal to the first molars (facial - 80 g and palatal - 80 g). (3) Distal to the canines (facial - 80 g) and distal to the first molars (facial - 150 g). (4) Distal to the lateral incisors (facial - 80 g) and mesial to the first molars (facial - 150 g). Vertical and horizontal movements of the teeth were measured.
resultsExtrusion movements were solely detected at buccal cusps of the first and second molars in the first model. Palatal movements of posterior teeth were detected in this model. Model II showed a homogeneous intrusion in anterior and posterior teeth and the amount of palatal movements of posterior teeth was reduced compared to model I. In contrast to Model IV, Model III had more intrusion in the posterior compared to anterior teeth. Facial movements of posterior teeth were detected in the third and fourth models. Incisor teeth showed facial movements among all of the models except for the lateral incisor in the third model.
conclusionsEach model of force application, causes different outcomes and side effects which is beneficial in certain clinical situations.
