Growth Modification is a discipline that focuses on the study and use of techniques and methods to regulate and control maxillofacial growth, the growth of the upper and middle jaws in humans. In specialist orthodontics, growth modification is critical because of its role in influencing the shape and position of the jaws and skull. Orthodontists who specialize in Growth Modification study the principles of growth and development of the face, skull, and jaws to understand how they can be modified with appropriate orthodontic interventions. Techniques and therapies associated with Growth Modification include the fitting of specialized orthodontic devices that utilize the natural growth of the individual to direct the growth of the jaws and skull according to treatment goals. This can involve the use of devices such as jaw retractors, growth regulators, and functional orthodontic devices. This study allows orthodontists to plan more effective and individualized treatments for patients, especially to address jaw growth imbalances that can affect facial function and aesthetics.

Multidisciplinary Orthodontic Treatment is a discipline group whose main focus is on the integration of orthodontics with various other disciplines, including maxillofacial surgery, periodontics, and dental conservation. This approach ensures that orthodontic treatment is performed by considering the multidimensional aspects that affect jaw structure and function, as well as dental health and aesthetics. Orthodontists specializing in Multidisciplinary Orthodontic Treatment understand the complex interactions between the teeth, jaws, supporting tissues, and overall oral function. They combine orthodontic knowledge and skills with principles of maxillofacial surgery, periodontics, and dental conservation to achieve optimal results. Techniques and therapies associated with Multidisciplinary Orthodontic Treatment may include fitting orthodontic devices along with maxillofacial surgical procedures to correct imbalanced facial structures. In addition, coordination with periodontics and dental conservation specialists may be required to ensure the health of supporting tissues and plan additional treatments such as dental implants or dental restorations. The important role of Multidisciplinary Orthodontic Treatment is to ensure that orthodontic interventions are in line with the goals of maxillofacial reconstruction and the health of the dental supporting tissues. This not only improves oral function but also improves the patient's facial aesthetics and smile.

Fixed Orthodontics is a discipline group whose main focus is on the development of knowledge, skills, and methodologies related to orthodontic treatment using fixed orthodontic devices. Fixed orthodontic devices include braces, brackets, and other supports that are permanently placed on a patient's teeth to correct the position and alignment of the teeth. Orthodontists who specialize in Fixed Orthodontics have an in-depth understanding of the mechanism of action, design, and application of different types of fixed orthodontic devices. They learn how to plan, fit, and maintain these orthodontic devices to correct tooth and jaw position, achieve desired aesthetics, and improve oral function. The importance of this research group lies in the proper application of knowledge about fixed orthodontics in planning and carrying out orthodontic treatment. This includes case analysis, treatment planning, selection of appropriate orthodontic devices, and periodic adjustments to ensure optimal tooth movement. Studies in this scientific group also involve an in-depth understanding of the biological response of dental tissues to fixed orthodontic devices. This allows orthodontists to minimize patient discomfort and maximize treatment efficiency.

Temporary Anchorage Devices (TADs) or mini-screws in orthodontics is a discipline group whose primary focus is on an in-depth understanding of the design, mechanism of action, fitting, and management of Temporary Anchorage Devices (TADs) in the context of orthodontic treatment. Orthodontists specializing in TADs study the biological and mechanical principles underlying the use of mini-screws as aids to improve orthodontic treatment efficiency and outcomes. They understand how to select appropriate locations, plan placement, and utilize TADs to support necessary tooth movement. Studies in this scientific group include careful evaluation of biological tissue responses to TADs placement and how to minimize negative impacts. In addition, orthodontists learn about proper fitting techniques, handling potential complications, and safe removal of TADs after use. The importance of this discipline group lies in the ability of orthodontists to utilize TADs as effective and appropriate aids in planning and carrying out complex orthodontic treatment. TADs allow for more precise tooth movement, better control, and more efficient treatment overall.
