Its main manifestations include defective bone mineralization and premature loss of primary teeth. This case report describes a patient with HPP who underwent orthodontic treatment using edgewise appliances. Despite the condition, no premature tooth loss or alveolar bone loss was observed. The patient presented with a skeletal Class II, Angle Class II molar relationship, and dental crowding. Orthodontic treatment began with the successful distalization of maxillary molars to confirm the possibility of normal tooth movement before starting ALP replacement therapy. After initiating ALP therapy, the maxillary and mandibular first premolars were extracted, and full-arch treatment started when the patient was 16 years, 9 months. Abnormal tooth movement and gingival recession were not observed. The treatment goals of achieving a favorable facial profile and acceptable occlusion were successfully met. Contrary to expectations of relapse in HPP patients, stable occlusion was maintained after 2 years of retention. This is because the patient had normal bone mineral density and used not only removable retainers but also canine-to-canine bonded flexible spiral-wire lingual retainers in the maxillary and mandibular arches. Long-term follow-up is crucial because of the high relapse risk associated with HPP. Further research on orthodontic treatment in patients with HPP is necessary to establish comprehensive guidelines and improve clinical outcomes.</div></div>","PeriodicalId":72140,"journal":{"name":"AJO-DO clinical companion","volume":"5 3","pages":"Pages 332-345"},"PeriodicalIF":0.0,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144271676","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}

However, the chemical composition of these aligners is not well understood, and their resistance to staining by coloring compounds present in the oral environment remains a concern. In this study, we aimed to analyze the chemical composition of multilayer aligner materials using chemical imaging and evaluate their staining resistance to common food and beverage items. The in vitro staining resistance of SmartTrack (Invisalign; Align Technology, Santa Clara, Calif) and ClearQuartz (ClearCorrect; Straumann Group, Basel, Switzerland) was tested by immersing the aligners in coffee, cola, red wine, and mustard for 24 hours. The color change was assessed using spectrophotometry. The aligners were analyzed using Raman microscopy to identify the chemical composition of the individual layers and relate them to staining resistance. Raman microscopy revealed that ClearQuartz consists of a soft elastomeric polyurethane layer sandwiched between two polyester layers, whereas SmartTrack has the opposite configuration. ClearQuartz exhibited less staining in all the tested foods and beverages than SmartTrack, which showed marked staining in mustard and coffee. Stain uptake was primarily observed in the polyurethane layer, possibly because of its chemical affinity with the coloring compounds. Clinicians should consider the patients’ dietary habits and aligner material composition before recommending a clear aligner treatment. Aligners with polyurethane elastomer as the outer layer are not recommended for patients who consume food and beverages rich in colorants, such as coffee and mustard, as this may detrimentally impact patient satisfaction and compliance.</div></div>","PeriodicalId":72140,"journal":{"name":"AJO-DO clinical companion","volume":"5 3","pages":"Pages 249-259"},"PeriodicalIF":0.0,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144271757","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}
