Special Extraction Treatment of Biocreative Orthodontic Strategy: Anterior Targeted Approach Using Preformed C-Wire

The C-WIRE technique represents an innovative method of orthodontic treatment of maxillary anterior teeth, particularly in excessive gingival display. This condition, which can significantly affect facial aesthetics, is caused by a combination of skeletal, dental, and soft tissue factors. In cases where excessive eruption of the maxillary anterior teeth is the main cause of gummy smile, traditional treatment approaches have included the use of intrusion arches and transpalatal arches, as well as temporary skeletal anchorage devices (TSADs). However, these methods often result in unwanted posterior tooth movements. The C-WIRE technique builds upon the segmented arch technique by selectively targeting the anterior segment for treatment, allowing for precise control and efficient force application. By utilizing skeletal anchorage systems and simplified force system, the technique facilitates effective intrusion and retraction of the maxillary anterior teeth, thereby potentially reducing gingival exposure and enhancing the patient’s smile aesthetics. This approach not only minimizes the need for posterior appliance attachments but also preserves the patient’s occlusal function. This paper suggests the biomechanical principles of the C-WIRE technique, providing a comprehensive overview of its components and treatment effects. Furthermore, clinical cases are presented to demonstrate the technique’s application in achieving desirable aesthetic outcomes.
