The COVID-19 pandemic opened the way for innovative medical education since the face-to-face teaching method for orthodontics before the pandemic was impracticable. This study assessed the acceptability of the learning strategies adopted for teaching orthodontics in the Southern Nigerian Dental schools during the COVID-19 pandemic by the students, the associated challenges faced by them, and their coping strategies. This was a descriptive cross-sectional study conducted among Southern Nigerian dental students using a semi-structured Google form questionnaire. Information on socio-demographic data, learning platforms adopted for teaching Orthodontics during the COVID-19 pandemic, acceptability of these platforms, possible challenges faced by the students, and their coping strategies were collected. Data was inputted and analyzed using descriptive statistics (mean and frequency) and inferential statistics (Z-test). The test of significance was set at P< 0.05. There were 118 participants, 64 (54.2%) males and 54 (45.8%) females with a mean age of 25.738+/- 2.94 yrs. The platforms adopted mostly include Zoom, WhatsApp, and Google Meet. Seventy-two (61.0%) respondents accepted the teaching platforms adopted during the pandemic and the challenges faced by the respondents were mainly lack of hands-on clinical sessions and network problems. Forty-seven (40%) of the participants coped by using self-directed learning, 20 (17.2%) used YouTube videos. Most of the students accepted the innovative teaching platforms adopted for teaching Orthodontics during the COVID-19 pandemic. Lack of hands-on clinical sessions was the major challenge faced by the students then and they coped well by using self-directed learning and YouTube videos.

Enhancing aesthetics, occlusion and functions is a primary motivation for individuals with open-bite malocclusion seeking orthodontic treatment. Open-bite malocclusion, characterized by a lack of vertical overlap of the anterior teeth, can be effectively treated with a combined surgical and orthodontic approach. In this case report, we present the treatment of a male patient with an open-bite malocclusion and a skeletal class II. Initially, the patient underwent a presurgical phase where fixed orthodontic appliance was bonded to achieve well-aligned arches, then came the maxillary impaction to normalize the overjet and overbite and enhance both aesthetics and functions.

The primary motivation for individuals with deep-bite malocclusion seeking orthodontic treatment is the improvement of aesthetics, occlusion, and functions. Deep bites can be treated by the intrusion of anterior teeth and the extrusion of the posterior teeth, or both, according to the exposure of the incisors in the smile. In this case report, we present the treatment of a female patient with a deep-bite malocclusion. This paper describes the clinical and radiographic changes with orthodontic treatment using Invisalign clear aligners and their effectiveness to normalize the overjet and overbite and enhance both aesthetics and functions.

Anterior open bite is a complex malocclusion that often requires comprehensive treatment due to its multifactorial etiology and high relapse potential. Conventional treatment options such as orthognathic surgery or extraction therapy may have limitations. Recent advancements in skeletal anchorage have introduced miniscrews as a minimally invasive and reliable alternative. This case report illustrates an 18-year-old female with sagittal skeletal Class II pattern, hyperdivergent facial type and class I molar and end-on Class II canine relationship, with an anterior open bite. The treatment plan consisted of using miniscrews placed bilaterally in the posterior maxilla to facilitate molar intrusion. A transpalatal arch was used to maintain transverse stability during the intrusion phase. The approach resulted in effective molar intrusion, closure of the open bite, and an improved facial profile.
