「Clear aligner therapy has expanded substantially in mixed dentition, yet the boundaries of clinical predictability across indications, movement types, and growth stages remain incompletely defined.」

「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.」

「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.」

「"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.」

「An internet search reveals at least 27 different clear aligner products currently on offer for orthodontic treatment.」

「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。.」

「Inflammatory periodontal diseases are highly prevalent, although most of these diseases develop and progress slowly, often unnoticed by the affected individual.」

「This review provides updates on acute conditions affecting the periodontal tissues, including abscesses in the periodontium, necrotizing periodontal diseases and other acute conditions that cause gingival lesions with acute presentation, such as infectious processes not associated with oral bacterial biofilms, mucocutaneous disorders and traumatic and allergic lesions.」

「This information will help the reader to understand not only the way that plaque may have an impact on oral tissues but also why regular effective cleaning may improve periodontal health and why some individuals appear to have a greater susceptibility to periodontitis than others, either intrinsically or in relation to various systemic factors.」

「A number of systemic disorders increase a patient's susceptibility to destructive periodontitis and have impacts on periodontal disease progression and severity.」
