This presentation examines the historical development and prospective trends of Taiwan’s orthodontic specialist certification system. Traditionally, the process comprised a written examination followed by an oral examination, in which candidates presented five self-prepared cases and one society-assigned case, both of which were required to pass.

In 2024, a major reform introduced a scenario-based oral examination into the assigned case component, designed to simulate real-world clinical decision-making and patient communication. Assessment topics may include etiology diagnosis, treatment planning, biomechanical principles, management of unexpected complications, patient communication, and medical ethics.

This change marks a paradigm shift from an outcome-oriented to a comprehensive competency-based approach, emphasizing real-time clinical judgment, problem-solving ability, and ethical decision-making, while reinforcing patient safety. The reform also aligns Taiwan’s system with global trends seen in international orthodontic board examinations.

Looking forward, the certification system is expected to incorporate digital case submission, cross-disciplinary clinical assessments, and periodic recertification to maintain professional excellence and ensure the highest standards of orthodontic care.

骨性第三類咬合不正的治療通常是在快速生長期結束後以矯正搭配正顎手術的方式進行。然而部分患者傾向採用非手術的保守型治療，而此類治療方式需要設計複雜的三維牙齒移動路徑，經常需使用骨釘來達成理想的牙齒移動，同時也需搭配其他輔助工具，包含第三類橡皮筋，單顆torquing spring等來控制牙齒移動時的副作用，以達到良好的torque control。本篇報告將透過精彩案例分享來具體解說各種Class III案例的不同torque control策略。

This lecture will delve into the efficacy and predictability of closing molar extraction spaces using clear aligners. We'll cover the biomechanical principles underlying clear aligner tooth movement, emphasizing anchorage control, root parallelism, and efficient space closure. Key strategies for enhancing predictability will be discussed, including precise diagnosis, strategic attachment placement, and the judicious use of auxiliaries like elastics and TADs. Clinical cases will illustrate successful outcomes and highlight common challenges. The goal is to equip attendees with the knowledge to maximize success in these complex clear aligner cases.

This lecture will delve into the effective integration of orthodontics and prosthetic restorations in the era of digital technology. We'll analyze how advanced tools like intraoral scanners, 3D printing, and CAD/CAM enhance diagnostic precision, treatment efficiency, and optimize both orthodontic and prosthetic fabrication workflows.

The core of this presentation emphasizes the crucial role of interdisciplinary collaboration. We'll share how orthodontists and prosthodontists can leverage shared digital platforms to develop comprehensive, personalized treatment plans. Through practical case studies, we'll demonstrate how orthodontic preparation creates optimal conditions for subsequent prosthetic rehabilitation and discuss integrated treatment strategies considering both esthetics and function. This lecture aims to provide clinicians with practical and forward-thinking insights to improve patient outcomes and satisfaction.

垂直向控制(vertical control)為齒顎矯正治療中達成理想咬合與美觀臉型的關鍵要素。透過前後齒列的垂直方向移動，可改善深咬與開咬等異常咬合，並對顏面外觀產生重要影響。根據過往文獻，隱形矯正在牙齒垂直向移動的控制表現上相對有限，在複雜病例中更具挑戰性。

本次報告將探討如何透過隱形牙套的設計優化，結合輔助矯正裝置達成有效的垂直向牙齒控制。並透過臨床案例解說不同垂直向問題的治療策略與結果，以提升隱形矯正於複雜臨床案例中的治療效能。

在醫學演進的過程中，不正確的因果關係推論是常見的邏輯錯誤，例如：吃麥當勞早餐→讓專注力提升，專注力提升→開刀表現變好，所以得到：吃麥當勞早餐→讓開刀表現變好。這樣的謬論常常會在我們身處的環境中出現，例如：拔牙與睡眠呼吸中止症的關係。

真正的因果關係，只有透過完整的研究設計與統計分析，以實證醫學的角度才能知道。因此本演講將分享以一個睡眠專科醫師及牙醫師的角度，來分享牙科治療與睡眠呼吸中止症的相關性，從如何篩選有風險的病人，當代的診斷方法，以及目前的最新治療趨勢，讓大家了解牙醫師在睡眠呼吸中止症中可扮演的角色。

在傳統咬合學中我們多以顳顎關節的骨性構造來決定顎間關係，在這個思路基礎上顎間關係甚至一度被認為是一個固定的機械關係。然而隨著牙醫界對呼吸道的關心越來越多，再加上在orofacial pain領域中我們對頸椎對下顎的影響也越來越關心，逐漸我們看到了頸椎、氣道、與下顎三者間互相連動的關係，這些在常涉及到顎位改變的矯正科醫師不得不慎。
