Among different patterns of facial cleft, complete bilateral cleft lip and palate (BCLP) is one of the most challenging cases for orthodontic and surgeons because of their deformed maxillary dental arch and severe skeletal discrepancy. It is also well known that CLP could occur as part of the phenotype in certain congenital diseases. However, from its extremely diversified phenotypic combination, some of the cases that we encounter remains difficult to diagnose. From these reasons, it is important to continuously report the outcome of orthodontic treatment in such cases which exhibit syndromic phenotypes with CLP.Material and Methods: In the present case report, an 18-year-old man with complete bilateral cleft lip and palate, skeletal Class III and open-bite with maxillary constriction, in addition to hypospadias, bubonocele, opisthotonus, and hypertonia was treated with edgewise appliance therapy combined with orthognathic surgery. The treatment began with surgically assisted rapid palatal expansion (SARPE) in anteroposterior and transverse dimensions with a three-way expander to increase the maxillary anteroposterior length and width. After the expansion, the patient underwent Le Fort I osteotomy and bilateral sagittal split osteotomy to correct skeletal Class III and open bite.Results and Conclusion: At the end of the surgical and orthodontic treatments, functional occlusion and an improved facial profile were achieved. We also discuss his diverse general phenotype due to his congenital disease.","PeriodicalId":43169,"journal":{"name":"Orthodontic Waves","volume":null,"pages":null},"PeriodicalIF":0.4,"publicationDate":"2020-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/13440241.2020.1751456","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47271121","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}

Results: Sudanese sample, in comparison to Caucasian, had a more convex profile with larger angle of convexity and more prognathic maxillae, obtuse lower face-throat angle, more acute nasolabial angle, protrusive upper and lower lips with deeper labiomental sulci and greater maxillary incisors exposure with larger interlabial gap. Males had greater maxillary and mandibular prognathism, more obtuse lower face-throat angle and vertical height depth ratio than females. Females had larger vertical lip chin ratio, maxillary incisor exposure and interlabial gap. Conclusion: Considerable differences between the soft tissue profile configuration of Sudanese and Caucasian adults exist and also between Sudanese and other populations. These variations should be taken into account during diagnosis and treatment planning of orthognathic surgery.","PeriodicalId":43169,"journal":{"name":"Orthodontic Waves","volume":null,"pages":null},"PeriodicalIF":0.4,"publicationDate":"2020-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/13440241.2020.1736784","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45756311","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}

Materials and methods: Indexed databases were searched up to March 2019, and the following eligibility criteria were imposed: (a) original clinical studies; (b) growing patients; (c) intervention: influence of ME on condylar position; (d) radiographic evaluation of condylar position before and after ME; and (e) statistical analysis. Experimental studies, historic reviews, case reports, cases-series, letters to the Editor, commentaries, studies that did not specify the type of posterior crossbite (PC), studies that included combined ME-facemask intervention, and studies in adult patients were excluded. Quality assessment was performed using the Methodological Index for Non-Randomized Studies (MINORS) guidelines. Results:Eleven clinical studies were selected for data extraction. In 3 studies, significant changes in condylar position were observed bilaterally with ME in patients with FUPC. One study showed significant changes in condylar position with ME only in the non-crossbite sides; and 2 studies found no significant changes in condylar position with ME in patients with FUPC. One study reported significant changes in condylar position in both sides with ME in patients with bilateral PC. In patients without PC, 1 study showed significant changes in condylar position bilaterally with ME; and 2 studies reported no significant changes in condylar position. The mean MINORS score was 13.8 2.89 (out of 24).

Aggarwal","doi":"10.1080/13440241.2020.1712823","DOIUrl":"https://doi.org/10.1080/13440241.2020.1712823","url":null,"abstract":"ABSTRACT Purpose: External Apical Root Resorption (EARR) is an undesirable but unavoidable side effect of orthodontic treatment. The various methods proposed for its evaluation, e.g. Intraoral Periapical (IOPA) X-ray and Orthopantomogram (OPG) x-rays use linear measurements which have errors due to magnification and angulations of x-rays. Root-crown ratio as measured on digital OPGs, which are essential diagnostic records for all orthodontic patients were used for the first time to assess root resorption. Methods: A two-step method was used, first to check the v alidation of OPG measurement with IOPA x rays. The first step involved the measurement of Root-crown ratio on digital OPG and IOPA by 5 independent examiners on IC measure software. The second step involved the measurement of root resorption as Root-crown ratio on pretreatment and post-treatment OPG X rays of 32 treated orthodontic patients all of which were treated by a single orthodontist. Digital OPG images of all patients were traced in Picassa software. In both steps, root-crown ratio was assessed by modified Lind method. Results: The results of first step did not show any significant differences in examiners to read the IOPA and OPG x rays. The results of the second step showed 11.8% root resorption in maxillary central incisors and 4% root resorption in lateral incisors. Similarly, maxillary and mandibular molars showed 1.6% and 5.1% resorption, respectively. The resorption in mandibular molars was significantly more compared to pretreatment value. There was apparently no effect of extraction treatment or treatment time on the amount of resorption. Conclusion: The study concluded that root-crown ratio can be used as an effective and efficient alternative method to quantify root resorption on OPG X rays and possibly alleviate the need for taking IOPA x rays in orthodontic patients thereby reducing the radiation exposure.","PeriodicalId":43169,"journal":{"name":"Orthodontic Waves","volume":null,"pages":null},"PeriodicalIF":0.4,"publicationDate":"2020-02-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/13440241.2020.1712823","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47847226","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}
