“…Indeed, this outcome may have been circumvented by opting for a non-extraction treatment option with conventional methods. [35][36][37] However, for this case, the extent of crowding was considerable and required space for the distalization of canines to achieve a Class I canine relationship. Few studies have reported the successful treatment of complex cases with clear aligners, and robust evidence through randomized controlled trials is lacking.…”

Clear aligners are a well-established alternative to conventional fixed orthodontic appliances for treating mild-to-moderate malocclusion. This case report details the successful treatment of a 14-year-old female patient with Class II malocclusion, crowding, and dental crossbite using extraction and the Invisalign® system. Achieving satisfactory anterior guidance by correcting the anterior crossbite and reducing the overjet and overbite was the primary treatment goal. Secondary treatment objectives included upper and lower midline alignment, leveling and alignment of arches, and achieving a Class I canine relationship for adequate canine guidance. Two sets of clear aligners were chosen; the first for alignment and the second for refinement. Extraction of teeth 14 and 24 were performed during the first aligner treatment phase, with space closure achieved by the distal movement of canine and posterior teeth mesialization. The second set of aligners refined the dentition by correcting the posterior open bite and extrusion of posterior teeth. Treatment duration was 13.5 months. By the end of treatment, the Invisalign system in conjunction with tooth extraction established an ideal overbite and overjet, corrected the crossbite, and achieved a Class I canine relationship with minimal disruption to the patient’s esthetic appearance. In addition, root axes were parallel and well controlled, despite extractions and space closure. Awareness of the dental biomechanics when clear aligners and extraction are used may be imperative for yielding successful outcomes for patients with Class II malocclusion and extractions.

“…To evaluate the permanent and mixed dentition, the Discrepancy Index used by the American Board of Orthodontics ( Figure 1 ) [ 23 ] was used to determine the difficulty of orthodontic treatment in a sample of clinical photographs and radiographs of children with OI as well as in a sample of healthy controls. Four degrees of difficulty were defined according to the score (low: 0–7 points; moderate-low: 8–15 points; moderate-high: 16–25, and high: >26 points).…”

Occlusion is the way in which the dental arches are related to each other and depends on craniofacial growth and development. It is affected in patients with Osteogenesis Imperfecta (OI) who present altered craniofacial development. The malocclusion present in 49 patients diagnosed with different types of OI aged between 4 and 18 was studied. The control group of healthy people was matched for age, sex, and molar class. To study the mixed and permanent dentition, the American Board of Orthodontics (ABO) discrepancy Index was applied. The primary dentition was evaluated with a Temporary Dentition Occlusion Analysis proposed for this study. The OI group obtained higher scores in the Discrepancy Index than the control group, indicating a high difficulty of treatment. The most significant differences were found in types III and IV of the disease. Regarding the variables studied, the greatest differences were found in the presence of lateral open bite in patients with OI, and in the variable “others” (agenesis and ectopic eruption). The analysis of primary dentition did not show significant differences between the OI and control groups. Patients with OI have more severe malocclusions than their healthy peers. Malocclusion is related to the severity of the disease and may progress with age.
