Structured PREreview of A NOVEL APPROACH TO RECOVERING OFF-TRACK ALIGNER TREATMENT THROUGH HYPER-ELASTIC POLYMER INNOVATION

Does the introduction explain the objective of the research presented in the preprint?

No

The introduction does not state the aim of the study. It is not until the methods section that reference is made to a comparison with OrthoFX and an industry standard.

Are the methods well-suited for this research?

Highly inappropriate

Key details required to verify or replicate the measurements are missing: measuring equipment/sensors, calibration, sample size per condition, number of repetitions, temperature/humidity, type of artificial tooth movement, clamping conditions, aligner thickness/material properties, manufacturing process, definition of ‘failed to provide any force’, statistical analysis, data aggregation from the claimed 7,680 data points. The benchmark ‘Industry Standard Aligner’ has not been defined. Without information on the manufacturer, material, thickness, manufacturing process, wearing time, geometry and number of standard aligners tested, it is unclear whether this comparison is fair, representative or generalisable.

Are the conclusions supported by the data?

Highly unsupported

It is not possible to conclude that the device offers greater comfort for patients based solely on the views of laboratory staff. The claim of “a more comfortable experience for the patient” is made without any patient surveys, pain scales, wear compliance or clinical outcome data. The claim of “quicker OTM times” is not substantiated by direct measurement of tooth movement. It appears that forces or force profiles were measured, rather than the actual speed or completeness of orthodontic tooth movement in vivo. Shorter clinical treatment times cannot be reliably inferred from force profiles alone. The claim that the Rescue Aligner eliminates “the mid-course correction process and associated appointments altogether” is unsubstantiated. The manuscript contains no systematic data on the frequency of corrections, the number of visits or the actual course of treatment.

Are the data presentations, including visualizations, well-suited to represent the data?

Highly inappropriate or unclear

The term “ideal biological force range” is claimed but not substantiated or operationalised. The “purple bar” at ±25 g and ±70 g respectively is presented as the “ideal biological force range”, without any source, tolerance range, clinical context or justification for the specific thresholds. This reference is central to any potential argument regarding superiority.

How clearly do the authors discuss, explain, and interpret their findings and potential next steps for the research?

Very unclearly

The term ‘comprehensive look’ is an exaggeration given the very limited range of movements. Only a few, selective movements on specific teeth were examined. This does not justify a comprehensive statement about aligner performance as a whole. The conclusion that it “contributes to quality of care” cannot be derived from the available data. “Quality of care” encompasses clinical outcomes, safety, the patient’s perspective, accessibility, process quality, etc. The manuscript does not provide any clinical or care-related endpoints in this regard. There are generalised claims of superiority (“clear-cut improvement”, “overall faster and more efficient solution”) without an appropriate basis for comparison.

Is the preprint likely to advance academic knowledge?

Not likely

No reliable, general improvement in the quality of care for patients can be inferred from this article. At best, it could serve as a preliminary hypothesis relating to materials and mechanics, but not as a sound basis for general treatment recommendations.

Would it benefit from language editing?

No

Would you recommend this preprint to others?

No, it’s of low quality or is majorly flawed

Is it ready for attention from an editor, publisher or broader audience?

No, it needs a major revision
