「With the aid of a 9-year follow-up case report, a simple direct technique associated with an orthodontic treatment for restoring the esthetic appearance of an impaired smile, with good short- and long-term outcomes, based on minimal but essential esthetic repair interventions is discussed.」

「This case report explains how to use the anterior ratio to help provide optimal aesthetics and function for the ortho-restorative patient.」

「To investigate the value of bracketless invisible orthodontic treatment combined with restoration in patients with anterior esthetic restoration.」

「This study shows that it is possible to provide the patient who suffers frJom malocclusion with proper correction, achieving the desired aesthetics by using lingual braces and pe?forming lingual orthognathic surgery.」

「Dental esthetic restoration covers from facial esthetics to dental esthetics, from the realization of macroscopic to microscopic esthetic restoration goals.」

「After clinical examination revealed esthetic alterations as generalized tooth yellowish discoloration, a slight diastema in the upper anterior region, and a shortened appearance of maxillary dental crowns, providing a gingival smile.」

「In contemporary dental care, an increasing number of adult patients are now seeking orthodontic treatment with the primary motive of improvement in appearance and achievement of esthetic smile.」

「We envision that it would be an ideal alternative for patients who pursue esthetic orthodontic treatment but were not likely to take lingual appliances or clear aligners.」

「This study aims to evaluate the safety margin of the osseointegration of orthodontic implants by investigating the healing process of the implant-bone interface through histopathological studies and quantitative determination.」

「The discipline of orthodontic aesthetics involves micro and macro aesthetics, gingival, and facial aesthetics.」

「A 24-year-old man complained about the appearance of his smile regarding color, shape, and position of the maxillary anterior teeth.」

「Materials and Methods: A 32-year-old female who presented with a persistent gummy smile of upper incisors and low upper midline frenum attachment post-orthodontic treatment, was seeking a better smile appearance.」

「The fibre-reinforced retainers had better patient satisfaction with aesthetics (MD 1.49 cm on a visual analogue scale, 95% CI 0.76 to 2.22; 1 study, 32 participants), and similar retainer survival rates (RR 1.01, 95% CI 0.84 to 1.21; 7 studies; 1337 participants) at 12 months.」

「The most affected dimensions were: facial aesthetics (p = 0.022), oral function (p = 0.051) and social aspects (p = 0.057).」

「In this technical note, the authors achieved accurate implant placement and precise fit of restoration with natural looking appearance; this patient-oriented-treatment led to a reduced healing time with better compliance.」

「Her intraoral examination showed complete healing of the area but an atypical appearance of the alveolar area of the missing tooth was observed in the periapical radiograph.」

「Clinical and radiographic examinations at the 6-year follow-up showed successful tooth replacement and an improved esthetic appearance achieved by this multidisciplinary treatment.」

「Progress of the aligners occurred every 3 days for the first 6 months; and every 5 days thereafter, for a total duration of 10.5 months.」

「After 3 months of uneventful healing and osseointegration, definitive telescopic crown prostheses were fabricated as the final restorations.」

「Following a five-month healing period, a series of precise prosthetic procedures, including abutment-level impressions, custom tray fabrication, and implant-level impressions, were performed to ensure optimal fit and functionality.」

「To evaluate alveolar bone dimensions and its relationship with tooth movement (retraction, intrusion and torque) during orthodontic treatment with fixed appliance and clear aligners.」

「This review aims to comprehensively analyze the effects of first versus second premolar extractions on anchorage loss, tooth movement, vertical dimensions, lip position, and third molar eruption in order to provide evidence-based insights for optimizing orthodontic treatment outcomes and guiding future research.」

「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.」

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

「Furthermore, comprehensive and accurate design combined with good application of growth potential can also enable invisible orthodontic technology to achieve perfect treatment effects in tooth extractions, providing clinical guidance for orthodontists.」

「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.」

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

「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。.」

「Within the study's limitations, piezosurgery demonstrated a reduction in postoperative discomfort, suggesting its advantage in enhancing patient recovery following lower third molar extractions.」

「The subjects were selected according to inclusion criteria: full permanent dentition (excluding third molars), Class II molar relationship (2.5-4 mm), no history of orthodontic treatment.」
