In an era of rapid digitalization, modern dentistry is developing as one of the most dynamic fields of medicine, shaping new clinical and educational paradigms.
A new Danish study compared the views of general dentists and orthodontists on indications and treatment planning with aligners in private practice, using surveys of the public and practicing clinicians with analytical data processing; the material includes discussion of ethical and educational aspects and allows practical conclusions to be drawn for clinical practice and curricula.
The study revealed systemic differences in perception, diagnosis, and readiness to use aligners between general dentists and orthodontists, which has a direct impact on the quality of case selection, treatment planning, and patient information provision.
The authors note limited public awareness of aligners in the population, with higher familiarity observed among young adults; patients more often learned about the method from a dentist or acquaintances, less often from advertising and social networks, which points to the key role of the clinician in the diffusion of innovations. Post-treatment satisfaction levels were high — the main motive for seeking treatment is aesthetic improvement, which not only influences the choice of therapy but also shapes expectations of outcomes; therefore, in clinical practice it is necessary to take motivational factors into account when choosing between aesthetics and functionality, optimize informed consent, and manage patient expectations.
Orthodontists significantly more often used lateral cephalometric radiographs and performed more detailed modifications of digital plans before the start of treatment; this emphasizes the role of high-precision digital tools in ensuring treatment predictability. Consequently, the diagnostic algorithm among specialists includes a comprehensive assessment of occlusion, skeletal relationships, tooth inclinations, symmetry, as well as digital validation of tooth movement trajectories and possible biomechanical limitations. Orthodontists also reported a lower level of satisfaction with treatment outcomes compared with general dentists — probable reasons: stricter clinical standards, a tendency to work with complex cases, and increased attention to occlusal details and periodontal factors.
Among general dentists the main barriers were cited as lack of experience and educational materials; orthodontists emphasized that for a number of complex three-dimensional movements fixed appliances provide more reproducible clinically validated results. For practitioners this means the necessity to integrate continuous professional development — including internships in digital planning, trainings in the biomechanics of movements with aligners, training in the IPR technique, use of buttons and elastics, as well as refinement algorithms — and the standardization of educational programs in order to reduce the competency gap between groups.
The authors emphasize the need for further research into differences in diagnosis and planning, as well as assessment of the quality of information flows provided to patients; methodologically it is important to consider the sample, possible selective patient selection by different groups of clinicians, and subjective satisfaction metrics. For clinicians, practical recommendations include: comprehensive full diagnostics using standard radiographic examinations and digital scanning, careful case selection taking into account the nature of the malocclusion and periodontal status, planning with allowance for refinement and with demonstrable criteria for outcome assessment, detailed informed consent with discussion of alternatives — including fixed appliances and their indications; additionally, a multidisciplinary approach is recommended for complex cases and registration of clinical outcomes for internal validation.
Reproducible educational programs are needed, including theory of digital planning and supervised practice under mentors, standardized protocols for diagnosis and planning, algorithms for indication selection and outcome registration; such measures will increase the predictability of clinical results and reduce the number of complications or dissatisfied patients. Regulatory and professional organizations can facilitate this through course accreditation, guideline development, and the creation of outcome registries.
The Danish study demonstrates that integration of digital technologies and cooperation between general practices and orthodontists are key factors for the safe and predictable implementation of aligner treatment; clinicians are recommended to focus on comprehensive diagnostics, correct case selection, standardized planning protocols, and a complete informed consent process to minimize ethical and medico-legal risks.
