Clinical expression of programmed maxillary buccal expansion and buccolingual crown inclination with Invisalign® EX30® and SmartTrack® aligners and investigating the effect of 1-week vs 2-week aligner change regimes: A retrospective study.
<p><strong><em>Objective:</em></strong> The objective of this retrospective cohort study is to assess and compare the accuracy of three different Invisalign<sup>® </sup>treatment regimens involving variations of aligner change frequency and type of aligner material in achieving maxillary dental buccal expansion.</p> <p> </p> <p><strong><em>Methods:</em></strong> 120 adult patients whose treatment involved maxillary dental expansion with Invisalign<sup>®</sup> were selected. Three groups, each of 40 patients were identified: SmartTrack<sup>®</sup> one-week changes (ST1), SmartTrack<sup>®</sup> two-week changes (ST2) and EX30<sup>®</sup> two-week changes (EX2). The groups were assessed by comparing actual changes achieved with those prescribed by ClinCheck<sup>®</sup>. The rates of clinically significant inaccuracies (CSI) seen for buccal expansion (≥ 0.5mm) and buccolingual inclination (≥2°) during expansion were then ascertained.</p> <p> </p> <p><strong><em>Results:</em></strong> With respect to expansion, the ST1 group showed the highest rate of CSI at all tooth levels studied while the ST2 group showed the lowest rate of CSI as well as the lowest mean inaccuracy for each tooth level studied. In terms of buccolingual inclination, the ST1 group displayed the highest rate of CSI across all tooth levels studied, while the EX2 group displayed the lowest rate of CSI at all tooth levels except for the canine level where the ST2 group displayed the lowest rate of CSI. A tendency toward overexpression of buccal crown inclination, and underexpression of buccal expansion was seen at all tooth levels.</p> <p> </p> <p><strong><em>Conclusions:</em></strong> Two-week aligner change regimens offer improved accuracy compared with one-week aligner changes. SmartTrack<sup>®</sup> two-week changes were the most accurate for buccal expansion, while EX30<sup>®</sup> 2-week changes were the most accurate for buccolingual inclination.</p>
3D Evaluation of Maxillary Expansion Methods
ClinicalTrials.gov study NCT07262892. IPD Sharing: YES. Countries: 1. Publications: 2.
Distribution. SW Brazil, known only from two sites, the type locality in Rondonia and Juruena (Mato Grosso State)Descriptive notes Head-body ¢.230 mm, tail ¢.80 mm. No specific data are available for body weight. Rondon's Tuco-tuco is medium-sized. Dorsal hairs are pale at bases and sepia at tips. Head and venterare slightly rufous, and tail is uniform brown. Skull is robust and depressed. Inter-maxillaries are also robust, with lateral protruding expansion; maxillaries are narrow; and mandible is strong and wide. Supraorbital process protrudes, and traverse occipital-temporal crest is straight. Bullae are inflated. in Ctenomyidae
