1 · What the graph read from it

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.

2 · The registry

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

backgroundCorrecting skeletal class III malocclusion with anterior crossbite in adolescents using only orthodontic treatment poses challenges. This report highlights a novel approach leveraging improved superelastic Ni-Ti alloy wire (ISW) to address these conditions effectively. CASE SUMMARY: A 17-year-old male patient presented with the chief complaint of an underbite. The patient was given a diagnosis of skeletal class III malocclusion and anterior crossbite. The orthodontic treatment plan was implemented and did not require teeth extractions or orthognathic surgery. Key interventions involved the application of ISW, intermaxillary elastics, and ISW unilateral multi-bend edgewise archwire. The unique combination of these techniques enabled the correction without the need for extractions or surgery. This approach leverages the advanced biomechanical properties of ISW, including its super-elasticity and shape memory, to enhance treatment efficacy. The treatment lasted 17 months, and major improvements in overjet, overbite, and alignment were achieved. The results were favorable, and stability was discovered during follow-up.

conclusionThe application of ISW for treating skeletal class III malocclusion with anterior crossbite in a 17-year-old male patient resulted in exceptional outcomes. The treatment led to a marked improvement in the patient's facial profile and to proper overjet, overbite, and midline alignment. These results were maintained over a one-year follow-up, indicating that a minimally invasive orthodontic approach can effectively address complex skeletal discrepancies in adolescent patients. This case illustrates that with the careful use of advanced orthodontic techniques, major skeletal challenges can be resolved without resorting to surgical procedures.
