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.
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。

The field of orthodontics strives to achieve an aesthetic, healthy, and stable occlusion. However, traditional practices often assess occlusion in maximum intercuspidation without adequately considering the biomechanics of the temporomandibular joint (TMJ), which can lead to overlooking critical occlusal factors. This perspective paper revisits the debate on the role of occlusion in temporomandibular disorders (TMD) and evaluates the efficacy of current treatment approaches, emphasizing the limitations of conventional methods and the lack of evidence supporting joint-oriented orthodontics. By integrating jaw tracking systems and digital workflows, a comprehensive evaluation of dynamic and static occlusion with realistic mandibular movement allows for a more individualized treatment approach to ensure optimal treatment outcomes.

Maxillary transverse deficiency presents challenges in orthodontic treatment, affecting approximately 4–17 % of the population and leading to various malocclusions and facial imbalances. Traditional treatments like Rapid Palatal Expander (RPE) have been effective, particularly in younger patients, but are associated with drawbacks and limitations, especially in non-growing individuals. Miniscrew-assisted rapid palatal expansion (MARPE) has emerged as a viable, safe, and cost-effective alternative for late adolescents and adults. Over the past decade, the MARPE has been widely used, leading to substantial clinical data. This narrative review aimed to revisit the crucial aspects related to treatment success, contributing factors, and various designs and protocols for MARPE. The MARPE designs, categorized as pure bone-borne, tissue bone-borne, and tooth bone-borne types, were compared along with their expansion patterns and the clinical implications were discussed. This review also focused on the long-term stability of MARPE and its potential complications.
