Abstract. This study aimed to evaluate the effectiveness of various corticotomy techniques based on digital dentistry in improving orthodontic treatment in adult patients. A total of 60 adult patients requiring orthodontic treatment were included and divided into two groups: a conventional orthodontic treatment group and a digitally guided corticotomy-assisted orthodontic treatment group. Digital imaging, three-dimensional treatment planning, and individualized surgical protocols were used to optimize clinical outcomes. The findings demonstrated that digitally guided corticotomy significantly accelerated orthodontic tooth movement and reduced the overall treatment duration compared with conventional treatment. Patients treated with corticotomy also exhibited favorable periodontal conditions, minimal postoperative complications, and a high level of treatment satisfaction. Digital dentistry improved the accuracy of diagnosis, surgical planning, and treatment monitoring, resulting in more predictable clinical outcomes. The integration of digital dentistry with modern corticotomy techniques represents an effective and reliable approach for enhancing orthodontic treatment efficiency, reducing treatment time, and improving patient-centered clinical outcomes in adult orthodontic patients.
