Patient introduction

Age: 19

Gender: Female

Patient initials: MRA

Treatment time: 13 months

Number of aligners: 39

Chief complaint: The patient, a 19-year-old woman, was evaluated to undergo orthodontic treatment using the Angel Aligner Pro system. She presents with a skeletal Class III, mesofacial, with a dental Class III malocclusion and a 2 mm deviation of the lower midline to the left. Teeth 33 and 43 are out of the arch and cortical bone, with a crossbite issue on tooth 33. Fortunately, no functional issues affecting swallowing or breathing have been detected. The patient’s motivation for starting treatment was a general review of her dental and aesthetic health. The soft tissue analysis reveals mandibular protrusion that influences her facial profile. This diagnosis highlights the need for a comprehensive approach to address dental and skeletal misalignments, improving both the patient’s functionality and facial aesthetics.

Treatment details

General Dentistry:

Solve gingivitis and reinforce the patient’s oral hygiene techniques to ensure optimal oral health.
Treat existing cavities with dental fillings to guarantee the integrity of the teeth before starting orthodontic treatment.

Orthodontics:

Distalization of the Third and Fourth Quadrants: Move the teeth distally in these quadrants to achieve a Class I relationship using the A8 protocol, improving the patient’s dental alignment and occlusion.

Solve the Crossbite of Tooth 33: Correct the position of tooth 33 to eliminate the crossbite, contributing to a more balanced occlusion.
Intrusion of the Lower Anterior Teeth: Adjust the vertical position of the lower anterior teeth to level the curve of Spee, improving the harmony of the occlusion.
Improve the Root Position of Teeth 33 and 43: Optimize the position of the roots of teeth 33 and 43 in relation to the cortical bone to ensure adequate bone support and long-term stability.
