The degree of irregularity in the alignment of the incisors was measured every 2 weeks using Little's irregularity index, and this was done at different time points throughout the study: before treatment (T0), after 2 weeks (T1), after 4 weeks (T2), after 6 weeks (T3), after 8 weeks (T4).\u0000RESULTS: A total of 87 patients with anterior mild crowding in the lower dental arch were initially assessed for eligibility. Out of these, 64 patients met the inclusion criteria. Eventually, 36 participants were assigned to receive the treatment. Accordingly, the data from 36 patients were analyzed statistically. There was no significant difference when comparing the two groups at T0, T1, T3, and T4. However, the difference was significant at T2 (p = 0.037). The differences were statistically significant at all time periods within each group (P < 0.001).\u0000CONCLUSION: The use of a modified aligner appliance with nickel-titanium coils effectively treats lower incisors crowding, but it does not accelerate the alignment process compared to the traditional fixed orthodontic appliance.\u0000\u0000","PeriodicalId":37056,"journal":{"name":"Dentistry 3000","volume":" 23","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140997233","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Solubility was evaluated by the percentage of material mass loss over 24 h and one week. The alkalinity was measured after each evaluation period using a pH meter. Other specimens were digitally radiographed on a size 2 sensor plate along with an aluminum step wedge to analyze the radiopacity by the Image J software.
