Correct planning and predictability of results in orthodontic therapy with clear aligners

ABSTRACT

Background:Digital technologies have revolutionized orthodontic treatment planning and management, offering new possibilities for diagnosis and treatment simulation. In particular, clear aligner systems represent a valid aesthetic alternative for adult patients, although they present some biomechanical limitations in terms of predictability of tooth movement.

Objective: To present a clinical case of orthodontic treatment with clear aligners in an adult patient, highlighting the digital planning, the biomechanical issues addressed, and the results obtained.

Clinical case: A 30-year-old patient with a Class I malocclusion, transverse contraction of the upper arch, and marked tooth rotations, particularly of tooth 3.5. The patient had previous partial orthodontic treatments and a suboptimal smile line. The treatment plan included the use of clear aligners with the goal of arch expansion, rotation correction, and improved smile aesthetics.

Conclusions: This case demonstrates how, through careful digital planning and targeted management, it is possible to successfully address complex malocclusions and rotations in adult patients. However, limitations persist in the predictability of some orthodontic movements with aligners, particularly rotations and angular movements.
