Methods: This cross-sectional study was conducted using a representative sample of 348 dental faculty members from master's and doctoral programs in Brazil. Data were collected using self-administered questionnaires between August and December 2018.

Class II Division 2 Subdivision Malocclusion in an Adult Patient treated with the Forsus Fatigue-resistant Device placed Unilaterally.

Treatment of Class II subdivision malocclusion is challenging, and orthodontists frequently struggle to determine the choice of treatment. Several treatment modalities have been proposed for correcting these types of malocclusion. Thus, the aim of this case report is to present dentoalveolar and facial outcomes achieved using an unilateral Forsus fatigue-resistant device combined with fixed appliances in an adult female patient presenting with Class II subdivision malocclusion.

Long-term stability of a Class III malocclusion with severe anterior open bite and bilateral posterior crossbite in a hyperdivergent patient.

Anterior open bite malocclusion is generally associated with several causes. This case report describes the 2-phase treatment of a 13-year-old boy with a Class III malocclusion, severe anterior open bite, and bilateral posterior crossbite treated without surgical intervention. An orthopedic approach was performed in phase 1 with a hyrax-type palatal expander, followed by maxillary protraction with a facemask for a 10-month period to promote the correction of transverse and sagittal deviations.

The Eye-Tracking Study of the Impact of the Gingival Margin Height of Maxillary Lateral Incisors.

The objective of this study was to verify differences in eye-tracking metrics and subjective smile esthetic ratings between general practitioners, orthodontists, and laypersons in cases of maxillary lateral incisor gingival margin deviations. Unilateral apical and incisal gingival margin deviations of 1, 2, and 3 mm were digitally produced in pictures of a man and a woman smiling. Specific areas of interest (AOIs) were created in each picture.

Nonsurgical treatment of skeletal maxillary protrusion with gummy smile using headgear for growth control, mini-implants as anchorage for maxillary incisor intrusion, and premolar extractions for incisor retraction.

An adolescent girl, aged 12 years 11 months, was evaluated for orthodontic treatment. Her chief complaints included a difficulty with keeping her lips passively closed and excessive gingival exposure upon smiling. Her treatment plan included (1) restriction of maxillary growth with cervical headgear, (2) extraction of the maxillary first premolars to reduce the maxillary protrusion and the mandibular second premolars to facilitate Class II dental correction, and (3) management of maxillary incisor intrusion via anchoring with mini-implants.

Biomechanics for Orthodontic Intrusion of Severely Extruded Maxillary Molars for Functional Prosthetic Rehabilitation.

The objective of this clinical case is thus to present a Class II, division 1, subdivision malocclusion with a severely extruded maxillary left hemiarch, which, due to the loss of mandibular teeth, makes prosthetic rehabilitation of the edentulous spaces impossible. A significant intrusion was performed with mini-implants followed by miniplates associated with fixed appliance and elastomeric chains. The results of this process showed that the biological responses of the teeth and the surrounding bony structure to the intrusion were demonstrated to be normal and acceptable.
