Cleft lip and palate (CLP) are prevalent congenital anomalies significantly impacting functional, aesthetic, and psychological aspects during critical developmental stages. Managing CLP requires an interdisciplinary approach involving craniofacial surgeons, pediatricians, otolaryngologists, orthodontists, prosthodontists, and other specialized professionals. Recent biotechnological advances have introduced innovative materials such as autogenous grafts, allografts, and platelet-rich plasma (PRP), known for their enhanced osteoconductivity and osteoinductivity properties. These biotechnologies aim to optimize bone tissue healing and regeneration treatment outcomes and address the multifaceted challenges associated with CLP. Two cases outline a combined approach utilizing homologous lyophilized bone graft with PRP followed by orthodontic movement of the primary canine into the grafted cleft site as a management alternative for CLP patients. This novel procedure provided an effective alternative treatment option for alveolar cleft repair in young children aged 4 to 9. It significantly reduced surgical complications and postoperative discomfort by eliminating the need for a donor site. Three successful options for early alveolar bridge reconstruction include bone matrix and plasma cellular reorganization, orthodontically guided movement of the primary canine through the bone graft, and the natural eruption of the upper permanent canine. These approaches allow patients to eventually complete their orthodontic treatment and oral rehabilitation, resulting in a full, permanent dentition. Moreover, it can positively impact functional and psychological aspects early in treatment, boosting patient confidence.

唇腭裂（CLP）是一种常见的先天性畸形，在发育的关键阶段显著影响功能、审美和心理方面。处理CLP需要一个跨学科的方法，包括颅面外科医生、儿科医生、耳鼻喉科医生、正畸医生、修复医生和其他专业人员。最近的生物技术进步引入了创新材料，如自体移植物、同种异体移植物和富血小板血浆（PRP），这些材料以其增强的骨导电性和骨诱导性而闻名。这些生物技术旨在优化骨组织愈合和再生治疗结果，并解决与CLP相关的多方面挑战。两个病例概述了一种联合方法，利用同源冻干骨移植物与PRP，然后将原代犬正畸运动到移植的腭裂部位，作为CLP患者的一种管理选择。这种新颖的方法为4 ~ 9岁幼儿的牙槽裂修复提供了有效的替代治疗选择。它通过消除对供体部位的需要，显著减少了手术并发症和术后不适。早期牙槽桥重建的三种成功的选择包括骨基质和浆细胞重组，正畸引导原牙通过骨移植物运动，以及上恒牙的自然喷发。这些方法使患者最终完成正畸治疗和口腔康复，形成完整的恒牙。此外，它可以在治疗早期对功能和心理方面产生积极影响，增强患者的信心。

This review provides an updated consensus regarding the inter-relationship between obesity and orthodontic treatment (OT). The authors focused on relevant studies that examined the impact of an increased body mass index (BMI) on craniofacial form and development, and OT-related parameters such as rate of orthodontic tooth movement (OTM), treatment compliance and duration, periodontal parameters and discomfort during OT. The currently available evidence indicates that an increased BMI is associated with alterations in craniofacial form, timing of dentoskeletal maturation, and facial soft tissue characteristics, which may have implications in orthodontic diagnosis and treatment planning particularly related to the timing of OT initiation. An increased BMI is associated with higher levels of oral proinflammatory and adipokine biomarkers and an altered periodontal tissue response during OTM. However, a clear association between BMI and rate of OTM could not be established. Nonetheless, a potential increased risk of periodontal inflammation during OT in patients with obesity should not be overlooked. Furthermore, a limited number of clinical studies indicated that patients with an increased BMI experience higher levels of pain during early OT, and the impact of obesity on treatment compliance remained controversial amongst studies. Obesity-related comorbidities and medications may further influence the inflammatory and periodontal tissue response during OTM; albeit further research is needed to clarify the underlying biological mechanisms. Orthodontists and dentists should incorporate BMI evaluation in the overall treatment diagnosis and educate patients about the negative impact of obesity on general and oral health.

这篇综述提供了关于肥胖和正畸治疗（OT）之间关系的最新共识。作者着重研究了身体质量指数（BMI）增加对颅面形态和发育的影响，以及OT相关参数，如正畸牙齿移动率（OTM）、治疗依从性和持续时间、牙周参数和OT期间的不适。目前可获得的证据表明，BMI的增加与颅面形态、牙骨成熟时间和面部软组织特征的改变有关，这可能对正畸诊断和治疗计划有影响，特别是与OT开始的时间有关。体重指数增加与口腔促炎和脂肪因子生物标志物水平升高以及牙周组织反应改变有关。然而，BMI与OTM率之间的明确关联尚不能确定。尽管如此，肥胖患者在OT期间牙周炎症的潜在风险增加不应被忽视。此外，有限数量的临床研究表明，BMI增加的患者在早期OT时疼痛程度更高，肥胖对治疗依从性的影响在研究中仍存在争议。肥胖相关的合并症和药物可能进一步影响OTM期间的炎症和牙周组织反应；尽管需要进一步的研究来阐明潜在的生物学机制。正畸医生和牙医应将BMI评估纳入整体治疗诊断，并教育患者肥胖对全身和口腔健康的负面影响。

To evaluate the influence of guided insertion on the success of paramedian palatal miniscrews the treatment of 103 patients was evaluated. The patients were divided into two groups. The miniscrews of group A (65 patients, 130 miniscrews; conventional insertion) showed a success rate of 97.69 %, those of group B (38 patients, 76 miniscrews; guided insertion) a success rate of 97.37 %). The differences were not statistically significant. Guided insertion of miniscrews did not lead to a higher success rate compared to conventional freehand insertion when inserting in the paramedian part of the T-zone. Likewise, root damage could be avoided even without guide. Operator bias, in the sense of an experienced operator should be taken into account when interpreting the results. Nevertheless, the guided insertion offers advantages regarding the workflow and simplifies insertion.

为了评估引导性插入对腭侧微型螺钉成功率的影响，我们对 103 名患者的治疗情况进行了评估。患者被分为两组。A 组（65 名患者，130 个微型螺钉；传统插入）的微型螺钉成功率为 97.69%，B 组（38 名患者，76 个微型螺钉；引导插入）的成功率为 97.37%。）差异无统计学意义。与传统的徒手插入相比，在引导下插入微型螺钉时，T 区旁的成功率并不高。同样，即使没有引导，也可以避免牙根损伤。在解释结果时，应考虑到经验丰富的操作者的偏差。不过，引导插入在工作流程方面具有优势，并简化了插入过程。

In recent years, there has been a growing trend in orthodontics to use the anterior palatal vault as an insertion site for temporary anchorage devices (TADs), to expand orthodontic possibilities and limit the collateral and unwanted dental effects. To improve accessibility and facilitate the procedure for clinicians, a guided approach for TAD insertion in the palatal vault, using insertion guides, has become increasingly prevalent. The manuscript primarily focuses on the real advantages and possible disadvantages that clinicians can expect when using insertion guides during TAD insertion into the palatal vault. Safety, precise evaluation of insertion depth, and the potential to execute a "one-visit protocol" are examined. Indeed, both direct and indirect palatal insertion protocols result to be efficient and safe in daily practice. The use of insertion guides result to be particularly beneficial for less experienced clinicians as well as for more complex patients and impacted teeth cases. Insertion guides can be created overlapping intraoral scanning to cbct or also to lateral teleradiograph, with sufficient accuracy and lower radiation exposure. However this method is limited in achieving bicortical evaluation, as well as relations to incisive canal and nasal floor. Finally a case report is presented, describing a full digital orthodontic treatment of a young adult patient presenting narrow maxilla. Slow maxillary expansion and fixed orthodontic treatment are described.

近年来，在正畸学中越来越多地使用前腭穹顶作为临时锚固装置（TADs）的插入点，以扩大正畸的可能性并限制附带和不必要的牙齿影响。为了提高临床医生操作的可及性和便利性，在腭穹窿插入TAD的引导方法，使用插入指南，已经变得越来越普遍。手稿主要集中在实际的优点和可能的缺点，临床医生可以预期使用插入指南时，TAD插入腭穹窿。检查了安全性、插入深度的精确评估以及执行“一次访问协议”的可能性。事实上，在日常实践中，直接和间接的腭插入方案都是有效和安全的。对于经验不足的临床医生以及更复杂的患者和阻生牙病例，使用插入导板尤其有益。插入导片可以创建与cct或侧位远摄片重叠的口内扫描，具有足够的精度和较低的辐射暴露。然而，这种方法在实现双皮质评估以及与锐管和鼻底的关系方面是有限的。最后，一个病例报告提出，描述了一个完整的数字正畸治疗的年轻成年患者呈现狭窄的上颌骨。缓慢上颌扩张和固定正畸治疗的描述。

The increased adoption of CAD-CAM technology parallels the expansion of digital dentistry internationally with orthodontics forecast to experience the highest level of associated growth. We aim to provide an overview of CAD-CAM workflows including different methods and materials for retainer manufacturing underpinned by best-available contemporary evidence. CAD-CAM approaches to fixed retention have led to streamlined workflows potentially reducing manpower issues while broadening both the material and design options. The ability to customize retainers also promotes improved anatomical adaptation. These advantages may translate into improved longevity and effectiveness of CAD-CAM retainers. Further studies are however required to evaluate the relative merits of CAD-CAM retainers on a long-term basis.

CAD-CAM技术的日益普及与数字牙科在国际上的扩展相一致，预计正畸学将经历最高水平的相关增长。我们的目标是提供CAD-CAM工作流程的概述，包括以当代最佳证据为基础的保持器制造的不同方法和材料。CAD-CAM固定保留方法简化了工作流程，潜在地减少了人力问题，同时拓宽了材料和设计选项。定制固位器的能力也促进了解剖适应性的提高。这些优点可以转化为CAD-CAM固位器的寿命和有效性的提高。然而，需要进一步的研究来评估CAD-CAM固位器在长期基础上的相对优点。

This issue of seminars revolves around digital orthodontics and showcases cuttingedge technology. It's not just a trendy new concept; all authors strive to add a balanced opinion and clinical conclusions to evaluate if this present technology is merely a hype feeding our FOMO or if it indeed provides significant advantages to patients and doctors alike. The digital orthodontics wave has been rolling on for over a decade. The spread of scanners, printers, and connecting software is visible in every country. Reasons to push and justify this hype—beyond the financial interests of companies—often include a lack of skilled employees, more complex cases, economic pressures, and the hope that automation might solve many challenges

本期研讨会围绕数码正畸技术展开，展示最新科技。这不仅仅是一个时髦的新概念；所有作者都努力添加一个平衡的观点和临床结论，以评估当前的技术是否仅仅是为了满足我们的FOMO，或者它是否确实为患者和医生提供了显著的优势。数字正畸浪潮已经持续了十多年。扫描仪、打印机和连接软件在每个国家都随处可见。推动和证明这种炒作的理由——除了公司的经济利益之外——通常包括缺乏熟练员工、更复杂的案例、经济压力，以及希望自动化可以解决许多挑战

Clinical reasoning is an essential competence to develop in the diagnosis and treatment planning of impacted maxillary canines to ensure good treatment outcomes. It involves skills of radiographic interpretation and mental visualization. To master these, postgraduate students learn to interpret 2D and 3D X-rays to locate these canines accurately. This process demands the creation of mental models of the impaction and resolving it either by envisioning the canine's movement to its correct position or considering its removal. To facilitate this cognitive exercise, a 3D-printed simulator, derived from Cone Beam Computed Tomography scans, serves as a tool to allow students to experiment with various movement simulations, helping them select the most viable treatment approach.

This project aimed to assess the differences in expert and novice orthodontists’ clinical reasoning for impacted maxillary canines, and whether the addition of a 3D simulator would affect their reasoning. Thirteen (13) novices randomly assigned to a control and intervention group and three (3) experts took part in a Think-Aloud exercise to diagnose and treatment plan a case of bilaterally impacted maxillary canines. Experts and intervention group novices had the 3D simulator in addition to standardized patient records. Their responses were recorded and analyzed according to a coding scheme reflecting the clinical reasoning process. While experts demonstrated quick clinical judgment and found the 3D simulator redundant, novices were more uncertain and required additional cues. Novices using the 3D simulator described more elaborate treatment plans and had increased awareness of potential complications as compared to the control group.

临床推理能力是上颌犬齿撞击的诊断和治疗计划中需要培养的一项基本能力，以确保良好的治疗效果。这涉及到X光片判读和心理可视化技能。为了掌握这些技能，研究生们要学习解读二维和三维 X 射线，以准确定位这些犬齿。这一过程要求建立阻生牙的心理模型，并通过设想将阻生牙移动到正确位置或考虑将其拔除来解决这一问题。为了促进这种认知练习，一个根据锥形束计算机断层扫描图像制作的 3D 打印模拟器可作为一种工具，让学生尝试各种运动模拟，帮助他们选择最可行的治疗方法。
