The treatment begins with the placement of anterior and posterior bite turbos to eliminate bite interference and address the crossbite. Subsequently, Class III elastics are utilized, followed by incisor elastics, to procline the upper incisors and retrocline the lower incisors effectively. 這篇報告描述一個治療CIII合併單側crossbite的案例。首先在前牙區和後牙區分別黏著bite turbos來去除咬合干擾，矯正錯咬。之後再先後使用Class III elastics 和前牙elastics來有效procline上門牙區和retrocline下門牙區。 </video> <video> Solving Overjet and Deepbite with Aligners - Part 1｜【Chris Chang Ortho】CC819 Description: [case report] This report documents the treatment of a Class II malocclusion with an impinging overbite, managed using IZC screws and aligners. During the course of treatment, #35 became off-track. At the refinement stage, a button was bonded to #35, and elastics were used to connect it to the IZC screws, effectively uprighting the tooth. 這篇報告描述如何使用IZC screws和aligners來治療CII合併impinging overbite。治療過中#35沒有按照預期的軌跡移動。在微調階段，在#35上黏著一顆button，再利用橡皮筋連接螺絲和button來扶正#35。 </video> <video> Skeletal Class III with posterior crossbite｜【Chris Chang Ortho】CC807 Description: [case report] In this challenging CIII(DI=43) case the treatment didn’t begin until the male patient has reached 18 after growth spurt has stopped. Extractions of 18, 28, 37, 47 and BS screws combined with CIII elastics were applied to distalize mandibular arch in the first treatment phase. Then criss-cross elastics were used to correct posterior crossbite. 這個複雜的CIII案例(DI=43) 中，我們等到這名男性患者滿18歲，快速成長期結束後才開始治療。第一階段先利用拔牙和buccal shelf screws，合併CIII橡皮筋的使用，來distalize下顎。接著合併criss-cross elastics來矯正後牙錯咬的問題。 </video> <video> Why Damon Ultima？Highlights of New Damon Ultima system｜【Chris Chang Ortho】CC816 Description: This presentation summarizes key comparisons between Damon Q and the latest Damon Ultima, specifically regarding the changes in slot design and wire shape. The new parallelogram slot design and round-sided rectangular wire offer more precise control and reduce wire bending. 本篇報告整理了Damon Q以及最新的Damon Ultima系統的差異，特別針對slot design和矯正線形狀的改變。 新的平行四邊形的slot和圓邊方線的設計，讓矯正醫師可以更準確控制牙齒的移動，同時減少彎線的需要。 </video> <video> Crowding & Posterior cross bite Aligner｜【Chris Chang Ortho】CC811 Description: </video> <video> Solving anterior Crossbite with Aligners｜【Chris Chang Ortho】CC808 Description: [case report] This is a CIII malocclusion with anterior crossbite treated with aligners. Such cases generally requires to create space to correct anterior crossbite. In this case without 3rd molars, non-extraction treatment combined with BS screws were planned to preserve good torque control. Then apply CIII mechanics by combining BS screws and CIII elastics to distalize the lower arch. 這是一個用隱適美改善三類咬合合併前牙錯咬的案例。通常這類案例會需要增加空間來矯正前牙錯咬。在沒有智齒的情況下，先嘗試不拔牙，而是透過BS screws和CIII elastics組成的CIII mechanics來將下排distalize，同時保留torque control。 </video> <video> Expansion in Aligners｜【Chris Chang Ortho】CC812 Description: </video> <video> Treatment of Skeletal Class I Malocclusion with Invisalign｜【Chris Chang Ortho】CC809 Description: [case report] This presentation features the treatment of a CIass I malocclusion combined with anterior crossbite and crowding. Three takeaways from this case: 1. Use the ext/non-ext table to determine if extraction is necessary. 2. Expand the narrow arch with aligners. 3. Correct anterior crossbite with aligners and tongue pressers. 本篇報告介紹了一個Class I合併牙亂和前牙錯咬的治療案例。本篇的三個治療要點包含：1. 利用拔牙與不拔牙的表格分析來決定是否需要拔牙。2. 利用隱形矯正器來將擴張過窄的牙弓。3.透過隱形矯正器和壓舌板矯正前牙錯咬。 </video> <video> U1 Impaction Treatment｜【Chris Chang Ortho】CC813 Description: </video> <video> U1 Impaction Treatment｜【Chris Chang Ortho】CC806 Description: [case report] This presentation features the surgical design and mechanics of an impacted upper central incisor. First, use closed eruption technique to access the upward impaction and then design an anchorage system combining a screw, elastics and a 3D-lever arm. Once the impaction has erupted, bond Damon’s low torque bracket and 14 CuNiTi wire to bring it to the occlusion. 本篇報告詳細說明該如何以手術暴露先上顎阻生門牙，黏上橡皮筋和3D lever arm，然後再表面縫合。透過此拉出牙齒的力學設計，促使阻生齒萌發。萌發後再黏上Damon的low torque bracket和14 CuNiTi 線將原本向上生長的阻生齒拉至咬合面。 </video> <video> Surgical Uprighting of impaction｜【Chris Chang Ortho】CC820 Description: Abstract: This video is part of a series that outlines the ideal conditions for surgically uprighting impacted teeth. It focuses on key factors such as the optimal angle, arc of rotation, and other critical considerations necessary for successful uprighting. 本影片是一系列的第一部分，概述了以手術扶正阻生牙的理想條件，包含最佳角度、旋轉弧度及其他所需的重要考量。 </video> <video> Primary Failure of Eruption｜【Chris Chang Ortho】CC815 Description: In this presentation, a patient with posterior open-bite, deep bite and spacing came for treatment. His conditions are typical of persons with primary failure of eruption(PFE) , an uncommon and yet very challenging issue for orthodontists. A brief summary of the cause and possible treatment options were discussed. 本篇報告中有一位患者有後牙開咬，合併深咬和牙縫過大的問題。他的情況符合一種特殊少見的問題：primary failure of eruption（PFE）。本篇簡介了相關的可能成因以及治療選項。 </video> <video> Anterior Deep Bite & Posterior X-bite：Efficient approach with Damon Ultima｜【Chris Chang Ortho】CC817 Description: [case report] This presentation features a CII malocclusion with anterior deep bite and posterior crossbite treated with the Damon Ultima System. Three takeaways from this case: 1. use the ext/non-ext table to determine if extraction is necessary. 2. Apply bite turbos in the anterior and posterior segment in two stages to correct crossbite and reduce excessive overjet. 3. take advantage of the Ultima system’s strength in precision control. 本篇報告介紹了一個以Damon Ultima治療Class II合併前牙深咬和後牙錯咬的案例。本篇的三個治療要點包含：1. 利用拔牙與不拔牙的表格分析來決定是否需要拔牙。2. 分兩階段利用bite turbos來矯正深咬和錯咬。3.利用Damon Ultima控制torque和angulation的優勢來準確移動牙齒。 </video> <video> Unilateral posterior crossbite｜【Chris Chang Ortho】CC814 Description: [case report] This presentation features the treatment of unilateral posterior crossbite. The key to this case is mechanics design. First, apply buccal shelf screw, power chains and cross-elastics to upright the lingually inclined tooth. Second, add bite turbo made by GIC to the opposing side to open up the bite. Third, let the occlusion to settle in time. 本篇報告介紹了一個單側後牙錯咬的治療案例。本篇的治療要點在於正確的力學設計。首先， 利用buccal shelf screw，power chains和cross-elastics把向舌側傾斜的後牙扶正。2. 在對側後牙區加上bite turbo來把咬合打開。3.讓咬合自然放鬆對咬。 </video> <video> Class I Deep Bite with Gummy Smile｜【Chris Chang Ortho】CC810 Description: </video>
