Abstract
Objective: To assess the impact of baseline malocclusion severity on the number of prescribed, used aligners and treatment duration.
Materials and methods: An unrestricted, independent search was conducted on the Invisalign ClinCheck database of a private practice for patients without any missing anterior teeth and whose treatment was finished between April 2021 and December 2024. Descriptive statistics were generated, and the feature selection Boruta algorithm (random forest algorithm) was implemented to identify important predictors for the number of aligners (prescribed, used) and treatment duration.
Results: A total of 404 patients were included (age: 29.57 [10.7] years). Mean numbers of prescribed, used and unused aligners were 72.21 (37.52), 65.63 (30.40) and 6.57 (14.09), respectively. Important predictors of the numbers of the prescribed and used aligners were relatively similar and included molar and canine relationships, maxillary crowding, overjet, presence and number of missing or extracted posterior teeth, overbite, presence and number of teeth in posterior crossbite and midline discrepancies. Treatment duration was associated with baseline maxillary crowding, molar and canine relationships, overjet, overbite, midline discrepancies and the presence and number of missing or extracted posterior teeth.
Conclusions: Factors related to the baseline malocclusion severity significantly affect the number of prescribed, used aligners and treatment duration. This information could be used for informed practice and patient communication, including future evaluation of the biological and environmental footprint of aligners.
期刊介绍：
Orthodontics & Craniofacial Research - Genes, Growth and Development is published to serve its readers as an international forum for the presentation and critical discussion of issues pertinent to the advancement of the specialty of orthodontics and the evidence-based knowledge of craniofacial growth and development. This forum is based on scientifically supported information, but also includes minority and conflicting opinions.
The objective of the journal is to facilitate effective communication between the research community and practicing clinicians. Original papers of high scientific quality that report the findings of clinical trials, clinical epidemiology, and novel therapeutic or diagnostic approaches are appropriate submissions. Similarly, we welcome papers in genetics, developmental biology, syndromology, surgery, speech and hearing, and other biomedical disciplines related to clinical orthodontics and normal and abnormal craniofacial growth and development. In addition to original and basic research, the journal publishes concise reviews, case reports of substantial value, invited essays, letters, and announcements.
The journal is published quarterly. The review of submitted papers will be coordinated by the editor and members of the editorial board. It is policy to review manuscripts within 3 to 4 weeks of receipt and to publish within 3 to 6 months of acceptance.
