Orthodontics treatment, while effectively correcting dento-maxillofacial deformity, often induces varying degrees of stigma in patients due to the use of orthodontic appliances. This negative psychological experience not only compromises patients' mental health and quality of life, but may also reduce their treatment compliance, potentially leading to treatment interruption. This article systematically reviews the core connotations of stigma, the specific manifestations of orthodontics-related stigma, its prevalence and current status, influencing factors, impacts on treatment outcomes and patient psychological behaviors, as well as coping strategies and intervention recommendations. It aims to help clinicians gain a more comprehensive understanding of stigma in orthodontics treatment and provide references for developing effective psychosomatic intervention programs, thereby facilitating the achievement of dual treatment goals in functional correction and mental health.
