It is regrettable that the study of the cervical spine is often ignored in the etio-pathogenesis of these dysmorphoses, particularly in cases of facial asymmetry.Objective: The aim is twofold: to encourage orthodontists and maxillofacial surgeons to make a systematic study of the cervical spine in craniofacial dysmorphoses and in particular craniofacial asymmetries, without claiming that they are becoming specialists in cervical spine pathology, and to introduce the necessary training in malformations of this anatomical region as part of the orthodontist specialisation curriculum.Material and methods: Conventional radiographic examinations can detect abnormalities of the cervical spine and cervico-occipital hinge. These anomalies can be clarified by additional radiographic exploration, conebeam, CT scan or others views.Results: Some craniofacial, facial and dentoalveolar asymmetries are caused by abnormalities of the cervico-occipital hinge. Conventional radiological examinations prescribed in dento-maxillo-facial orthopaedics can be used to detect unrecognized spinal anomalies and inform patients or parents, thereby ensuring the practitioner's responsibility.Discussion: The three components-atlas, axis and occipital-are confused in a complex embryological process that explains the polymorphism of malformations in this region.Conclusion: Any vertical and/or transverse facial and dento-alveolar asymmetry requires systematic investigation of the cervical spine as a whole and of the cranio-spinal joint in particular in search of any abnormalities.","PeriodicalId":101415,"journal":{"name":"L' Orthodontie francaise","volume":"95 4","pages":"355-365"},"PeriodicalIF":0.0,"publicationDate":"2025-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143019795","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}

Ankylosis may be uni- or bilateral. The complications of this ankylosis affect the functions of mastication, swallowing and phonation, sometimes facial morphology, and disturb dental hygiene. The aetiologies are, in order of frequency, post-traumatic, infectious, inflammatory and congenital.Material and methods: The authors present an algorithm for the management of temporomandibular ankylosis. Management is always surgical, with at least resection of the ankylosis mass and bilateral coronoidectomy. Additional procedures are performed depending on the presence of dental articulation disorders, age and loss of ramus height. Early, aggressive and prolonged post-operative rehabilitation is essential to ensure that the mouth remains open and that there is no recurrence.Conclusion: This complex pathology needs to be well understood in order to make a precise diagnosis and offer appropriate treatment.","PeriodicalId":101415,"journal":{"name":"L' Orthodontie francaise","volume":"95 4","pages":"367-377"},"PeriodicalIF":0.0,"publicationDate":"2025-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143019759","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}

Planning of orthognathic surgery requires a three-dimensional (3D) examination to visualize deformities. Nevertheless, the use of cephalometric analysis on 3D imaging remains clinically modest. The main objective of this study was to compare the cephalometric measures obtained from frontal radiographies and 3D imaging in patients with facial asymmetries.Material and methods: Frontal radiographies and 3D CT scans used for orthognathic surgery planning of 24 patients with asymmetries were selected. Cephalometric points were manually placed on 2D and 3D images by an operator, twice at a 4-week interval. The asymmetry of the subjects was quantified from 12 measurements, then the data obtained in 2D and 3D was compared. Intra-examination repeatability has been calculated.Results: 2D-3D average differences above 2 mm were found in the quantification of mandibular, jugal and maxillary molar symmetry and in the measurements of mandibular symmetry. The 3D measures showed a better repeatability than the 2D measures.Conclusion: The 2D-3D variations observed could have a clinical impact in the diagnosis and management of patients with facial asymmetries. Other studies remain necessary to provide more clinical evidence of the benefits of 3D cephalometry.","PeriodicalId":101415,"journal":{"name":"L' Orthodontie francaise","volume":"95 4","pages":"335-345"},"PeriodicalIF":0.0,"publicationDate":"2025-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143019756","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}

These asymmetries, whether mandibular, maxillary, or dental, require a deeper understanding of their causes and their aesthetic and functional impact. Additionally, associated functional imbalances must be addressed for comprehensive management. Traditional diagnostic methods, such as 2D radiographs and plaster models, have significant limitations, now overcome by the use of 3D technologies (intraoral scanners, Cone Beam Computed Tomography, photogrammetry).Objective: This article aims to demonstrate how these technologies enhance the understanding and precise management of craniofacial anomalies.Material and methods: The clinical case presented involves a 28-year-old female. The results obtained using 3D imaging are compared with traditional methods and initial simulations, highlighting their advantages.Discussion: 3D imaging opens promising perspectives in orthodontics, particularly in personalized treatments and innovative approaches such as mandibular kinetics (transition to 4D). Moreover, the increasing integration of artificial intelligence into diagnostic and treatment planning tools adds further value, streamlining decision-making and improving clinical efficiency.Conclusion: 3D imaging represents a turning point in the evaluation and treatment of facial asymmetries. By providing a clearer and more detailed view of anatomical structures, it allows orthodontists to design more precise and personalized treatment plans. These advancements lead to optimized clinical outcomes and improved patient compliance.","PeriodicalId":101415,"journal":{"name":"L' Orthodontie francaise","volume":"95 4","pages":"379-412"},"PeriodicalIF":0.0,"publicationDate":"2025-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143019777","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}

Radiographically, PVI is characterized by an elevation of the mandibular angle in relation to the base of the odontoid. Among the etiologies, congenital disorders are the most frequent, dominated by condyle hypoplasia. First and second branchial arches syndromes are most often associated to soft-tissue malformations, while acquired etiologies (post-traumatic, ankylosis and rheumatic) are scarce. Therapeutic management requires close collaboration between orthodontist and surgeon and involves alternative orthognathic surgical procedures. Three techniques are described along with their expected results: chondro-costal grafting, vertical retro-spinal lengthening using the Caldwell-Letterman technique, and intra-oral supra-basilar osteotomy.Discussion: Although the clinical presentation can be frustrating in children, facial asymmetry usually increases during pubertal growth. Early treatment with dentofacial orthopedics can sometimes restore growth. In other cases, collaboration between orthodontist and surgeon is more necessary than ever to correct asymmetry, sometimes using unconventional surgical technique.","PeriodicalId":101415,"journal":{"name":"L' Orthodontie francaise","volume":"95 4","pages":"439-449"},"PeriodicalIF":0.0,"publicationDate":"2025-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143019771","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}

Its treatment requires close collaboration between the orthodontist and the maxillofacial surgeon. In case of mild cant, treatment consists in coordination of dental arches followed by mandibular osteotomy. For more severe asymmetries, mandibular and maxillar surgery may be necessary to straighten the occlusal plane. However, this procedure can be disproportionate when the cant is moderate. The objective of our case series is to describe an orthodontic-surgical protocol straightening the occlusion plane using bite planes and miniscrews, without surgery of the maxilla.Material and methods: The protocol is based on the creation, the day before the mandibular surgery, of bite planes with asymmetric thicknesses, allowing the surgeon to fix the mandible horizontally in frontal plane. Bite planes are removed a few weeks after surgery. Elastic tractions supported by miniscrews placed on the lower arch allow maxillary teeth extrusions.Results: Through the four clinical cases presented, we observed a straightening of the occlusal plane and a facial harmonization.Conclusion: This orthodontic-surgical protocol may be interesting for mild to moderate occlusal cant, avoiding a Le Fort I osteotomy.","PeriodicalId":101415,"journal":{"name":"L' Orthodontie francaise","volume":"95 4","pages":"413-438"},"PeriodicalIF":0.0,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143019751","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}

A systematic review was conducted to analyze the effects of resin removal after the debonding of orthodontic brackets using different mechanical instruments, from both a qualitative and quantitative perspectives.Materials and methods: An electronic search, following PRISMA guidelines, was conducted across three databases until March 2023, supplemented by a manual search. All controlled randomized studies or in vitro studies, comparing the removal of adhesive with tungsten carbide burs to other mechanical instrumentation techniques and assessing enamel surface, were included.Results: Twenty-seven eligible articles were included, comprising two randomized studies and 25 in vitro studies, with varying bias levels. Compared to tungsten carbide burs, ultrasonic instruments and sandblasting showed similar or better results in terms of enamel loss and surface roughness. The enamel surface was equally less rough when using discs (Sof-Lex) or a fiberglass bur, or a fiberglass bur, although these techniques were time-consuming. The exclusive use of a diamond bur, stainless steel bur, or manual scaler for complete resin removal resulted in much rougher surfaces, clinically unacceptable.Conclusion: Preserving the enamel surface seems optimal with a two-phase protocol, involving the use of tungsten carbide burs for initial removal of most of the resin, followed by a less invasive technique for finishing resin removal. Beyond the findings of this review, a final polishing step also appears to be relevant.","PeriodicalId":101415,"journal":{"name":"L' Orthodontie francaise","volume":"95 3","pages":"261-280"},"PeriodicalIF":0.0,"publicationDate":"2024-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142670213","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}
