“…However, beyond these considerations, all data recorded suggest that the presence of vestibular brackets does not affect consistently the reliability of IOS. Hence, as reported in other studies in the literature, 10,17,18 scanning with the brackets in situ can be recommended for routine clinical practice. While there is some Likewise, the data in this study showed minimal, not statistically significant (R ≃ 1, P > .05) intra-arch linear discrepancies in both the upper (−0.01 mm ± 0.43 mm) and the lower arch (−0.09 mm ± 0.52 mm) when the scans were taken with the brackets and orthodontic archwire in situ (match 2).…”

“…They also reported a percentage coincidence between scans acquired directly and those acquired indirectly of about 98.86% ± 0.95% after performing digital superimpositions. 10 While several studies have previously investigated the accuracy of IOS of both arches with brackets in situ, highlighting generally good trueness and precision, only one, by Jung et al, 19 has investigated the effect of the presence of the orthodontic archwire. The authors reported very little influence of orthodontic archwire on the accuracy of measurements of both inter-molar and inter-canine distances.…”

“…The IOS images with brackets bonded to the vestibular surface of the dental elements yield more faithful reproductions of the gingival areas of each tooth, preventing the stretching that may plague conventional impressions. 9,10 In addition, the IOS images of the arches during orthodontic treatment can be useful in the production of robotically-bent archwires during the finishing phases, in both vestibular and lingual fixed orthodontic treatment. 11,12 For example, Tong et al described a lingual approach that routinely uses IOS in order to reproduce tooth position at any time of the orthodontic treatment, which can be especially useful in the design of fully customized robotically-bent NiTi archwires in the fine-tuning phase.…”

“…In addition to those already mentioned, a further advantage of intraoral scanners is the possibility of acquiring digital models with fixed appliances in situ, with or without the archwire, which would be impossible when using conventional physical impression materials for the latter. The IOS images with brackets bonded to the vestibular surface of the dental elements yield more faithful reproductions of the gingival areas of each tooth, preventing the stretching that may plague conventional impressions 9,10 . In addition, the IOS images of the arches during orthodontic treatment can be useful in the production of robotically‐bent archwires during the finishing phases, in both vestibular and lingual fixed orthodontic treatment 11,12 .…”

“…The process of acquiring intermediate IOS with fixed appliances in situ is now also routine in the field of orthognathic surgery. The aims are to simulate the physical movement of the basal bones before the surgical phase 10 or to plan the latter digitally (virtual surgical planning, VSP), using computer‐assisted surgery (CAS) software 14 . In the latter case, the ability to reproduce the arches with appliances in situ is essential to obtaining adequate matching with the volumetric data acquired via cone beam computed tomography (CBCT) and to manufacture precise surgical splints 15 .…”

ObjectiveTo evaluate any distortion produced by multibracket fixed orthodontic appliances on digital models obtained from intraoral scans (IOS), considering the presence of both brackets only and brackets/archwire combination.Setting/SampleThe IOS data of the arches of 20 patients (12 females and 8 males; mean age = 15.55 ± 2.84 years) were acquired using the CS3600 intraoral scanner (Carestream Dental, Atlanta, USA), without any appliances (model A), with vestibular brackets alone (model B) and then with brackets and orthodontic archwire fitted (model C).Materials and MethodsData were acquired between the months of January and October 2021 at the moment of indirect bonding phase. On each model, five intra‐arch linear measurements were obtained (inter‐canine, inter‐premolar 1 and 2, inter‐molar and arch depth), and after digital matching between model A and B (match 1) and A and C (match 2), the linear discrepancies were evaluated at 20 points (10 occlusal and 10 gingivolingual) previous identified on the reference model A. All measurements were performed using Geomagic Control X software (3D Systems, Morrisville, USA), and any dimensional variations and distortions were evaluated by the linear regression analysis and two‐sample t‐test (P ≤ .05).ResultsThe results show an almost perfect correlation between both models B and C and the reference model A, both as regards the intra‐arch linear measurements and the linear discrepancies found at the 20 identified points.ConclusionsMultibracket fixed orthodontic appliances do not produce any relevant distortions in digital models obtained via intraoral scanning. Therefore, the removal of archwire is not mandatory before IOS.
