Expert Consensus on the Evaluation of Orthodontic Treatment Outcomes

Area of Science:

• Orthodontics
• Dental Research
• Evidence-Based Dentistry

Background:

• Current orthodontic outcome evaluation relies heavily on subjective judgment and international indices inadequate for Chinese populations.
• A need exists for a culturally tailored, objective framework to assess orthodontic treatment success in China.

Purpose of the Study:

• To develop and introduce a novel, systematically calibrated expert consensus for orthodontic treatment outcome evaluation specific to Chinese patients.
• To establish a standardized, 3D framework integrating occlusal, root/bone health, and facial profile assessments.

Main Methods:

• A comprehensive literature review and analysis of existing indices (PAR, ABO-OGS).
• A large-scale correlation study involving 65 experts evaluating 216 cases.
• Development of a 3D evaluation system with detailed specifications for indicators, measurements, and scoring.

Main Results:

• A 3D orthodontic evaluation system was established, covering occlusal relationships, root and bone health (mandating CBCT), and facial profile harmony.
• The system includes specific indicators, measurement methods, and a five-grade classification system.
• This framework represents the first mandatory inclusion of 3D radiographic evaluation in orthodontic outcome standards.

Conclusions:

• The developed expert consensus provides a standardized, scientific foundation for orthodontic treatment quality control and specialist certification in China.
• This framework aims to enhance the overall quality of orthodontic care by offering objective morphological evaluation criteria.
• The system is designed for future integration of functional assessment and long-term stability evaluations.
