Dental arch dimensional changes in deep bite adults treated with orthodontic fixed appliances in conjunction with maxillary incisor vs. canine bite turbos during the levelling and aligning phase: a randomized clinical trial.
Introduction: This randomized clinical trial compared arch dimensional changes, dentoskeletal changes, and the rate of overbite correction in deep bite adults treated with fixed appliances and either maxillary incisor bite turbos (IBT) or canine bite turbos (CBT).
Materials and methods: Forty-six deep bite subjects treated with fixed appliances were randomized into IBT (n = 23) and CBT (n = 23) groups. Changes in intercanine width (ICW), arch height (AH), and Little's Irregularity Index (LII) were analyzed from before treatment (T0) to 3 months after aligning with 0.012" NiTi archwires in both arches (T1). Cephalometric changes between T0 and the visit when normal overbite was achieved (T2) were assessed. Within-group and between-group comparisons were analyzed at a significance level of 0.05.
Results: In both groups, mandibular ICW, and maxillary and mandibular AH significantly increased while maxillary and mandibular LII decreased. Maxillary and mandibular incisor proclination and molar extrusion were observed. The IBT group showed significantly greater changes in mandibular ICW, maxillary and mandibular AH, and mandibular incisor proclination than the CBT group. However, the overbite correction rate and the LII reduction were not significantly different between the groups.
Conclusions: The IBT and CBT produced similar effects on arch dimensions and dentoskeletal changes. However, the IBT group demonstrated greater arch dimensional changes.
Clinical relevance: Clinicians may consider IBT if flaring incisors is desired. Alternatively, CBT is better for cases with limited incisor proclination and where minimizing arch dimension change is needed, such as in narrow ridge situations.
Clinical trial registration: The trial was registered at Thai Clinical Trial Registry on https://www.thaiclinicaltrials.org , under the identifier TCTR20230811013.
期刊介绍：
The journal Clinical Oral Investigations is a multidisciplinary, international forum for publication of research from all fields of oral medicine. The journal publishes original scientific articles and invited reviews which provide up-to-date results of basic and clinical studies in oral and maxillofacial science and medicine. The aim is to clarify the relevance of new results to modern practice, for an international readership. Coverage includes maxillofacial and oral surgery, prosthetics and restorative dentistry, operative dentistry, endodontics, periodontology, orthodontics, dental materials science, clinical trials, epidemiology, pedodontics, oral implant, preventive dentistiry, oral pathology, oral basic sciences and more.
