數位化牙科Digital Dentistry 已經推廣30餘年，早期從牙冠，植牙製作，逐漸在牙科其他領域使用,矯正治療也成為重要的一環。最初透明牙套治療病人，醫師基本上不涉及製造端，而且對牙齒各種移動方式不能全盤掌握。大家只能在黑箱中摸索。最早的突破口是In-house aligner的出現，隨著高效能的個人電腦和軟體的進步，矯正醫師終於可以在診所按照自己的設計製造透明牙套。但無論廠商或In-house aligner，這些第一代透明牙套的材料都類似，屬於熱壓式牙套 Thermoformed aligner，廣泛的研究發現它們臨床表現並不理想。很慶幸大約5年前市場出現第二代嶄新的透明牙套，運用3D列印技術製造而且新的樹脂材料和上一代完全不同，具備型狀記憶效果。近年AI技術普及也應用在移動牙齒的設計軟體，所以現在矯正醫師已經可以掌握高效能的In-house aligner. 本次演講會詳述Thermoformed aligner 和最新的3D printed aligner有何不同， 另外也提出創新的技術應用在矯正臨床治療。

Value-based orthodontic treatment emphasizes precision in diagnosis, strategic treatment planning, the use of elegant approaches, and minimally invasive techniques to ensure a comfortable and positive experience for patients.

In the current clinical practice, however, there is a growing tendency among orthodontists to prioritize complex mechanics and procedures over accurate diagnosis and sound orthodontic principles. This often results in overtreatment, with unnecessary appliances crowding the oral cavity, leading to patient discomfort, difficulties in eating and maintaining hygiene, increased clinical risks, and on-call burdens for the orthodontist.

Orthodontics, at its core, is a discipline that blends aesthetics and medical logic. Successful outcomes rely not solely on the tools employed, but on the orthodontists’ ability to formulate logical, individualized treatment strategies grounded in accurate diagnosis. Even with conventional appliances, innovative thinking can yield highly effective solutions for complex cases.

This lecture will present a variety of clinical cases, demonstrating how streamlined techniques and logical strategies can elegantly and effectively achieve optimal treatment results. The objective is to highlight that true innovation in orthodontics is not defined by technological novelty but by the refinement of clinical reasoning and a return to thoughtful, patient-centered care.

顎位到底是可變還是不變，尤其成人患者，在矯正治療中一直是個謎。為什麼有些案例我們可以 觀察到顎位的改變，有些卻無法？本次報告將探討，如果顎位是可被變動的，那麽事前如何審慎評估，並設計有利於顎位變化的牙齒移動，以改正jaw bone discrepancy，藉由改正顎位來促進facial expression muscles balance，讓患者能得到協調美好的外觀，達到醫病雙贏。

這場演講聚焦於兒童的兩階段隱形矯正治療，從Phase I 的空間管理與常見挑戰開始，延伸到Phase II 的拔牙決策與臉型設計。透過數位模擬與CBCT的應用，結合實際病例的比較分析，探索隱形矯正在兒童領域中的新想法。如果你也曾在兒童隱形矯正 Phase I 療程後面對家長質疑「怎麼看起來變暴牙了？」，這場演講絕對切中痛點，本次將深入解析這個讓許多醫師困擾的問題，並分享如何用不同的設計與策略，讓治療走得更穩、更遠。

Maxillary incisor torque control is critical during space closure, particularly in cases of severe protrusion with minimal crowding. This presentation introduces the design, biomechanics, and clinical applications of the Double-J retractor—a customized appliance supported by palatal miniscrews that enables controlled, bodily retraction of the maxillary incisors. The force system is designed to direct the retraction force vector through the center of resistance of the anterior segment, while auxiliary torquing springs guided by palatal miniscrews provide additional torque control. Cephalometric superimpositions from clinical cases demonstrate excellent anchorage preservation, torque control, and vertical control, especially when combined with a transpalatal arch and cantilever clips. A finite element analysis was also conducted to examine the optimal placement of miniscrews and the magnitude of activation. The biomechanical principles of the Double-J retractor closely resemble those of Dr. Burstone’s torquing arch, making it an effective option for managing high-angle Class II protrusion cases with upright incisors and bony protrusion. Furthermore, this system allows for esthetic retraction without fixed appliances and may be integrated with clear aligner therapy, offering versatility in complex treatment scenarios.

The conventional camouflaged treatment for a Class II retrognathic mandible usually emphasizes on retraction of maxillary dentition for the occlusion, instead of improving the retrognathic mandible for the profile. It has been a challenge and myth in orthodontics for improving a retrognathic mandible in Class II D1 adult patient without orthognathic surgery, especially in average to low angle patients. To improve the Class II retrognathic mandible and occlusion, bite raisers has been proposed for establishing a habitual Class I jaw bone relationship by forward repositioning of the mandible. By using the bite raiser together with direct printing aligners built-in with pushing dots/re-enforced LHA or TPA for aligner retention, anterior teeth alignment, and posterior teeth lateral expansion/distalization/mesialization/extrusion, the purpose of this presentation is to propose a hybrid aligner treatment protocol for a Class II D1 retrognathic mandible in adult patients for improving both of the occlusion and facial profile trough case reports. The rationales and designs for the bite raisers and aligner pushing dots also will be presented.

治療雙顎前突患者的成功關鍵在於正確的個案選擇與診斷、明確的治療目標，以及精準的治療計畫。藉由CBCT 影像與ClinCheck®軟體的整合，提供一個功能強大且高效的平台，讓醫師能夠在同一系統中完成診斷與治療規劃，配合附件（attachments）設計，以及適當的排程（staging），不僅能預測牙齒移動的結果，提升牙齒控制力，更能大幅簡化治療流程並縮短療程時間。
