Orthodontic correction of Class II skeletal malocclusion complicated by deep bite using clear aligners: A case report

This case report describes an orthodontic treatment using clear aligners in a patient with Class II malocclusion associated with a deep bite. A 16-year-old patient with skeletal Class II malocclusion presented with a retrognathic profile, a deep bite of 7 mm, deep curve of Spee, proclined incisors, spacing, an excess Bolton discrepancy in the mandible, lower midline shift 2 mm to the right, and long clinical crowns. The patient preferred aligners over traditional fixed orthodontic appliances. The treatment objectives were achieved in 2.2 years, and the patient was pleased with the aesthetic and treatment outcomes. Using aligners along with proper auxiliaries and attachments is an effective method of addressing orthodontic difficulties, such as Class II complicated with deep bites in a reasonable time. Further, clear aligners offer less pain, better oral hygiene, and more aesthetics comparable to that of conventional fixed orthodontic appliances.
