Kyung-A Kim Department of Orthodontics, Kyung Hee University College of Dentistry, Seoul, Korea. Clear aligners and lingual appliances represent two prominent esthetic orthodontic treatment modalities, each relying on distinct biomechanical principles and set-up philosophies. While both systems utilize digital treatment planning, their approaches to force delivery, control of tooth movement, and overcorrection differ substantially. Clear aligner therapy is based on staged dig

Seung-Wook Oh Department of Orthodontics, Kyung Hee University College of Dentistry, Seoul, Jin-Young Choi Department of Orthodontics, Kyung Hee University College of Dentistry, Kyung Hee University Dental Hospital, Seoul, Korea CAD/CAM technology has significantly transformed orthodontic diagnosis and appliance fabrication by enabling precise digital planning and individualized bracket and archwire design. While both labial and lingual orthodontic systems benefit from digit

You-Sun Lee Department of Orthodontics, Korea University Anam Hospital, Seoul, Korea Lingual orthodontics provides a highly esthetic treatment alternative but remains technically demanding due to limited access, complex lingual tooth morphology, and sensitivity to appliance positioning. Traditionally, successful lingual treatment has depended on meticulous manual set-up procedures and indirect bonding protocols, which are highly operator-dependent and prone to variability. In

Sang-Ho Noh Lingual orthodontics has become an important esthetic alternative to conventional labial appliances; however, successful treatment outcomes depend largely on precise appliance positioning and accurate set-up procedures. Because access to the lingual surface is limited and the lingual morphology of teeth is highly variable, lingual orthodontics requires greater planning accuracy than labial treatment. This review summarizes the evolution of traditional lingual appl

Byung-Young Yeo The head of Gaba Orthodontic Dental Clinic, Seoul, Korea In lingual orthodontics, the precise expression of bracket prescriptions is important owing to the proximity of the brackets to the center of resistance of the tooth. This study explores the key strategies for maximizing treatment efficacy in lingual orthodontics, highlighting the importance of meticulous setup and the use of indirect bonding systems, such as jigs and transfer trays. Proper arch wire pla

Hyun Joo Yoon The Line Orthodontic Clinic, Yongin, Korea Lingual orthodontics requires precise bracket positioning to ensure successful treatment outcomes due to the unique challenges of limited visibility and diverse lingual tooth morphologies. This study explores the pivotal role of setup models and indirect cores (jigs) in addressing the aforementioned challenges. Indirect bonding systems, as opposed to direct methods, enable meticulous bracket placement facilitated by set

Ji-Sung Jang Yonsei HAU Orthodontic Clinic, Jinju, Korea Lingual orthodontics distinguishes itself from labial orthodontics mainly through the positioning of its appliances on the lingual side of the teeth, altering force application points and tooth movement mechanics. This biomechanical difference enables orthodontists with experience in labial techniques to transition to lingual orthodontics. In the leveling and alignment stage, the shorter lingual arch perimeter necessita
