「Key words:Orthodontics, risk factors, third molar, tooth extraction.」

「To study the results of an easy orthodontic extraction method for impacted lower third molar removal which had roots compressing to the inferior alveolar nerve (IAN).」

「The extraction of permanent first molar (PFM) teeth with poor prognosis allows the build of a new-and-ideal occlusion with the spontaneous movement of the healthy second and third molars by taking advantage of the patient's development.」

「Tooth extractions, apart from the third molars, which it seems is normal to extract today, have always given rise to controversy among orthodontists with both supporters and opponents.」

「To present a novel orthodontic approach for minimally invasive extraction of impacted mandibular third molars (M3s) close to the inferior alveolar nerve (IAN).」

「Preorthodontic socket preservation after tooth extraction is intended to enhance favorable dentoalveolar ridge morphology and architecture, and facilitate orthodontic tooth movement (OTM) and extraction space closure.」

「In case it is necessary to extract a tooth and the options are the third molars, partially or totally unerupted, and teeth that belong to other dental groups, obviousness recommends - due to mouth anatomy and physiology, as well as pathologic reasons - extracting the third molars, due to of the several reasons described in the present study.」

「This study aimed to investigate the associations between tooth extraction, age, and tooth position from both maxillofacial surgical and orthodontic perspectives.」

「Methods: Fifty-three IMTM in contact with inferior alveolar nerve (IAN) that underwent tooth extraction in the Department of Oral and Maxillofacial Surgery Peking University School of Stomatology from January 2022 to June 2023 were included, with coronectomy and microimplant anchorage implantation in the first stage of the surgery, root traction was achieved with orthodontic elastic and microimplant anchorages by about 5.886 N of force, when the IMTM root was detached from IAN, a second surgery was performed to extract the residual root.」

「Overall extraction rate, excluding third molars, was 58%.」

「The content of the guidelines is based on monographs and literatures on the clear aligner orthodontic treatment in the past five years, and the clinical consensus of all the members of Expert Group for Writing Project of Clear Aligner Technology.」

「To analyse through a systematic review the effectiveness of clear aligners by assessing: (a) predictability of clear aligners and (b) treatment outcome comparison of clear aligner therapy with fixed appliance therapy.」

「"Guidelines for clear aligner orthodontic treatment (2021)" proposes clinical treatment recommendations in terms of practitioner requirements, clinical risks, diagnosis, treatment plan, and common clinical strategies for the orthodontic clear aligners technology.」

「Background and Objectives: Recent advances in dentistry include microbiological and metabolomic analyses, which have the potential to improve the understanding of oral microbiome-host imbalances during orthodontic treatment.」

「The study, based on the modified Delphi method, collected the opinion of experts, comparing it with the scientific literature to evaluate the potential and limitations of orthodontic aligners, obtaining 47 consensus statements related to biomechanics and extraclinical factors.」

「Proper selection of cases and reasonable design in clear aligner treatment are expected to obtain tooth alignment, good intercuspation, normal overbite and overjet, periodontal health, parallel roots, and to achieve the goal of aesthetic, functional, stable, and healthy orthodontic treatment. 术者诊断设计不当、矫治技术应用失误、正畸治疗后的复发以及患者依从性较差无法配合矫治等原因可导致患者对矫治结果不满意，寻求二次矫治。此类患者通常已减数，或伴牙周、关节、牙体或缺牙等问题，常需多学科联合治疗，二次矫治难度较大，可选方案受限。无托槽隐形矫治舒适美观，具备数字化精准化程度高、可个性化排牙模拟矫治后终末状态等特点，使其在失败病例的二次矫治中具有一定优势。本文通过展示无托槽隐形矫治在二次矫治病例中的应用实例，对矫治设计和监控细节进行讨论和总结。建议医师在接诊前利用无托槽隐形矫治难度评估工具对患者情况进行评估，接诊自身诊疗能力范围内的病例，以获得满意的矫治疗效。无托槽隐形矫治技术治疗减数病例的成功关键在于诊断正确，选对病例。在方案设计上，二次矫治应注意前牙转矩的恢复，利用推磨牙向后获得间隙，做好垂直向控制，改善后牙咬合关系。在无托槽隐形矫治中正确选择、谨慎纳入、合理设计，有望在二次矫治的疑难病例中获得牙排列整齐、尖窝交错、覆(牙合)覆盖正常、牙周健康、牙根平行的矫治效果，达到美观、功能、稳定、健康的矫治目标。.」

「In this paper,the problems related with adult orthodontic treatment were reviewed.」

「Clear aligner therapy (CAT) has rapidly evolved as a preferred orthodontic treatment option due to its aesthetic appeal, comfort, and removability.」

「Corticotomy and dental distraction have been proposed as effective and safe methods to shorten orthodontic treatment duration in adolescent and adult patients.」

「This study investigated the effects of different mini-screw anchorage techniques on the three-dimensional (3D) movement of anterior and posterior teeth during maxillary anterior retraction with clear aligners in extraction cases, aiming to provide guidance for clinical orthodontic practice.」
