Given the heterogeneity of practices, devices used and follow-up modalities, the French Society of Dentofacial Orthopedics (Société Française d'Orthopédie Dento-faciale or SFODF), a scientific society, has proposed Clinical Practice Guidelines (CPG) for orthodontic retention. This article presents the method used to develop the CPG full-text and the guidelines produced.Material and method: A review of the literature was carried out after a bibliographic search of databases. The CPG full-text and guidelines were drafted, graded according to the level of evidence, then reread, discussed and validated by the workgroup's experts. A second review by a group of external experts was then carried out before final validation of the CPG for publication.Results: Of 652 articles selected, 53 met the inclusion criteria and were used to prepare the CPG full-text containing 41 grade C items and 23 expert agreements, constituting 40 guidelines.Discussion: There is still no consensus on the choice of materials. The literature remains poor on the functions. Some appliances which are more used in France are poorly documented in the literature.Conclusion: The CPGs provide recommendations on the factors to consider before using a retainer, the effectiveness of the different devices, their failures and adverse effects, as well as the follow-up procedures.","PeriodicalId":101415,"journal":{"name":"L' Orthodontie francaise","volume":"96 -","pages":"e1-e13"},"PeriodicalIF":0.0,"publicationDate":"2025-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144328351","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}

This study provides an updated analysis of international recommendations concerning the use of CBCT in orthodontics, with a particular focus on clinical indications, radiation dose reduction, and recent technological advancements.Material and methods: A systematic review of guidelines published between 2015 and 2025 was conducted following the PRISMA methodology. Inclusion criteria comprised official directives from recognized scientific societies and clinical studies evaluating low dose protocols in orthodontics.Results: The analysis of the 19 retained recommendations reveals a consensus regarding the primary indications for CBCT in orthodontics, particularly for impacted teeth, skeletal anomalies, periodontal and upper airways assessment. Dose optimization and the integration of artificial intelligence emerge as major advancements, enabling significant radiation reduction while preserving diagnostic accuracy.Conclusion: The development of low dose protocols and advanced reconstruction algorithms presents promising perspectives for safer and more efficient imaging, increasingly replacing conventional 2D radiographic techniques.

Transplantation allows for the postponement or avoidance of implant placement, helps preserve the quality and quantity of space and bone, serves as a maintainer of bone and keratinized tissues, and, in optimal cases, authorizes certain orthodontic movements. The objective of this article is to propose an autotransplantation protocol in the form of a management diagram.Material and methods: The management diagram was developed based on literature and our clinical experience.Results: The key clinical considerations are patient selection, 3D printing of replicas of the tooth to be transplanted using Cone Beam imaging (with elongated apices and gripping rod), preservation of periodontal tissues, minimizing extra-alveolar time (preferably through a two-step procedure or preliminary avulsion and site preparation), positioning the tooth in infraocclusion, and ensuring flexible and not overly prolonged support.

However, an overly restrictive interpretation of these recommendations has led to excessive conservation of 3rd molars. Late avulsion of these teeth entails considerably higher risks for the patient, compared with extraction between the ages of 16 and 20. The aim of this article is to illustrate, through a series of cases, the risks associated, on the one hand, with excessive retention of 3rd molars and, on the other hand, with the surgical complications associated with their avulsion too late.Material and methods: Fifteen cases are detailed: infections, pericoronary cyst with suborbital extension, bucco-sinusal communication, tuberosity and mandibular fracture, neuro-sensory disorders.Discussion: Before the age of 15, the root formation of poorly formed and deeply impacted 3rd molars is incomplete and they are often deeply impacted, making their avulsion difficult and the post-operative after-effects significant for patients. Beyond the age of 25, the risk of paresthesia and fracture of the mandible increases significantly, and becomes problematic after the age of 30.Conclusion: The period between 16 and 20 years of age represents a \"window\" where surgical risk and post-operative consequences are minimal. Avulsion of the 3rd molars may sometimes be indicated to prevent surgical difficulties and complications in the event of ultrasonic avulsion. Beyond the age of 25, or even 30, the benefit/risk ratio must be assessed particularly rigorously, even if this means considering therapeutic abstention (accompanied by appropriate monitoring) when possible.","PeriodicalId":101415,"journal":{"name":"L' Orthodontie francaise","volume":"96 1","pages":"105-125"},"PeriodicalIF":0.0,"publicationDate":"2025-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144083091","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}

Providing a better understanding of the medical risks faced by orthodontists helps to enhance the safety of their day-to-day practice. The aim of this article is to present the claims experience of orthodontic practitioners.Material and methods: The annual claims experience of dental surgeons was analyzed. All data on claims and their evolution from one year to the next were studied. The number of procedures is presented, along with their breakdown into civil, ordinal and criminal procedures, and the dental disciplines involved.Results: In 2023, 1,980 claims were submitted by dentists, giving a claims ratio of 6.5%, compared with 6% in 2022. Unlike other medical professions, the vast majority of claims are settled out of court. In dentofacial orthopedics, it's the indication and implementation of treatment that comes top of the list of complaints, ahead of relapse.Discussion: The contentious aspect of claims is due, in the vast majority of cases, to poor communication between patient and practitioner, hence the importance of providing patients with appropriate information as part of the care contract. Following a review of the typology of medical accidents specific to the profession, the legal obligations incumbent on both dental surgeons and their patients are discussed.Conclusion: Rigorous clinical practice by the practitioner, combined with compliance with legal obligations and appropriate, responsive clinical and relational follow-up, enhances a relationship of trust with the patient and helps to avoid subsequent blaming.","PeriodicalId":101415,"journal":{"name":"L' Orthodontie francaise","volume":"96 1","pages":"127-133"},"PeriodicalIF":0.0,"publicationDate":"2025-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144083080","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}

Early diagnosis and preventive strategies are essential. This study explores the etiological factors, diagnostic tools, and early orthodontic interventions aimed at minimizing complications associated with impacted canines.Methods: This review explores genetic and environmental etiological factors, current diagnostic techniques - including panoramic radiography and Cone Beam Computed Tomography (CBCT) - and interceptive strategies such as early extraction of primary canines, maxillary expansion techniques, and strategic extraction of permanent teeth.Results: Early extraction of primary canines significantly improved the spontaneous eruption of permanent canines in 87% of cases. Failures were associated with greater initial angulation, more severe displacement of the canine, inflammation of the pericoronal sac, and the absence of root resorption of primary canines.Discussion and conclusion: Early and precise diagnosis, along with appropriate interceptive treatments, significantly reduces the complexity and duration of subsequent orthodontic or surgical interventions.

During the Renaissance, the search for ideal proportions was a major focus of scholarly thought. In the 18th and 19th centuries, anthropology took over, and with the advent of the X-ray, cephalometry began to be applied to orthodontics. The aim of this article is to describe the evolution of cephalometry and assess its role in 2025.Materials and methods: The article is based on a literature review.Results: Cephalometric analyses based on profile teleradiography did not emerge until the 1930s, becoming an essential diagnostic tool that soon revealed both its value and limitations. Analytical approaches -whether typological, dimensional, or architectural- varied according to their proponents and were often grounded in their personal conceptual frameworks, leading to ongoing debates.Discussion: Since the 2000s, the introduction of lower radiation 3D imaging (CBCT) has revolutionized the field, where access to volumetric data has transformed routine practices thanks to the richness of the images. Moreover, 3D imaging can be combined with other digital examinations, enabling, for example, the visualization of treatment objectives within an anatomical, individualized, three-dimensional context. However, 2D cephalometric analysis remains a fundamental measurement and control tool, particularly for assessing incisor axis orientation.Conclusion: We are at a turning point: The information provided by profile teleradiography is now limited compared to what can be drawn from 3D analyses. This calls for a tiered approach to prescribing examinations, tailored to each patient's specific needs.","PeriodicalId":101415,"journal":{"name":"L' Orthodontie francaise","volume":"96 1","pages":"7-22"},"PeriodicalIF":0.0,"publicationDate":"2025-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144083089","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}

Only photographs of cases with more than one year of follow-up are presented.Results: The complete series included 12 cases, 7 of which have a follow-up period exceeding one year. The patients were aged between 13 and 34 years. Most of the teeth involved were immature (4 out of 7 cases before Nolla stage 10). The length of follow-up varied, with some cases monitored for up to 3 and a half years. The main indication was replacement of a decayed tooth with a third molar. Three cases involved different situations: impossibility to perform traction as a first-line treatment (due to a severely dystopic tooth) or as a second-line option (due to ankylosis and resorption). One tooth was lost due to excessive milling of the neo-alveolus and active retention. The fallback solution in this case was implant placement. One tooth remained in slight infraocclusion.Discussion: Although the routine preservation of third molars should not be standard practice, the wide range of indications (caries, teeth refractory to traction, etc.) calls for a careful assessment of the pros and cons of extracting third molars and consideration of their usefulness, for example for autotransplantation.","PeriodicalId":101415,"journal":{"name":"L' Orthodontie francaise","volume":"96 1","pages":"59-78"},"PeriodicalIF":0.0,"publicationDate":"2025-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144083081","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}
