Consequently, we selected specific treatment strategies based on the conditions of the 3-dimensional positions, including the angle between the canine teeth and the midline, as well as the degree of overlap with the lateral incisors. In addition, because of the impaction of multiple premolars and the close positional relationship of the impacted teeth on the right side of the maxilla, we applied orderly traction to the impacted teeth, emphasizing the use of light force throughout the treatment process. On completion of the treatment, Class I molar and canine occlusion with ideal overbite and overjet was achieved. There were no signs of root resorption, and the roots were parallel. This case report demonstrates that the treatment approaches for impacted canines and multiple impacted teeth should be based on their positional and anatomic features, using orthodontic traction or inducing spontaneous eruption as necessary.</div></div>","PeriodicalId":72140,"journal":{"name":"AJO-DO clinical companion","volume":"5 1","pages":"Pages 114-126"},"PeriodicalIF":0.0,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143395569","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}

The JET system shortened the overall treatment duration by leveling, canine distalization, and detailing simultaneously under the regional acceleratory phenomenon (RAP) induced by premolar extraction. Indirect bonding initiated the detailing from the beginning, a 3-dimensional slot self-ligating bracket system for smooth sliding mechanics, and superelastic nickel-titanium wires and coil springs to apply light continuous forces. RAP is a tissue response to noxious stimuli (eg, tooth extraction) characterized by an increased healing capacity of the affected tissues. A 13-year-old girl with Class II subdivision malocclusion, infralabioversion of the maxillary left canine, rightward deviation of the mandibular midline, and crowding of the mandibular anterior teeth underwent orthodontic treatment using the JET system. Light continuous forces were used for efficient tooth movement to reduce pain during orthodontic treatment. The orthodontic appliance was provided soon after the extraction of the maxillary first premolars and mandibular left first premolar and adjusted once a month. Active treatment was completed within 7 months, after which anterior crowding and occlusion were improved. The panoramic radiograph showed no significant reduction in alveolar crest height, but slight apical root resorption was observed. The JET system can shorten the duration of orthodontic treatment in patients during the RAP stage induced by tooth extraction.</div></div>","PeriodicalId":72140,"journal":{"name":"AJO-DO clinical companion","volume":"4 6","pages":"Pages 434-444"},"PeriodicalIF":0.0,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143179939","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
