This paper describes the orthodontic treatment of two cases that were successful in winning the British Orthodontic Society (BOS) Membership in Orthodontics (MOrth) Cases Prize in 2019. The first case describes the management of a 12-year-old girl with a Class II division 2 malocclusion complicated by moderate upper and lower arch crowding, multiple unerupted teeth, restored lower first permanent molars, pseudo-transposition of the lower left lateral incisor and canine, and diminutive upper lateral incisors. Treatment involved a combination of an upper removable appliance followed by upper and lower preadjusted edgewise fixed appliances. Anteroposterior correction and overbite reduction was achieved with triangular Class II elastics with posterior occlusal disengagement. Both upper permanent canines were exposed and aligned, and the diminutive upper incisors built up with resin-based composite. Treatment was completed over a period of 23 months. The second case describes the management of a 13-year-old boy with a Class II division 2 malocclusion complicated by severe upper and lower arch crowding with unerupted UR5, UL4, LR3, rotated LR5, an increased overbite complete to tooth, buccally displaced upper canines and hypoplastic upper first premolars. Treatment involved a first phase of functional appliance therapy, followed by the extraction of UR4, UL4, LL5, LR4 and upper and lower preadjusted edgewise fixed appliances over a 28-month period.

Lip sucking and lip biting in the primary-dentition period can cause the upper incisors to tip labially and the lower incisors to collapse lingually with the lower lip wedged between the upper and lower anterior teeth. The resulting lip incompetence further aggravates maxillary protrusion. Thus, there is a causal relationship between lip sucking/lip biting and maxillary protrusion. Orofacial myologists provide lip training to activate the flaccid upper lip and raise the child's awareness to help stop the sucking or biting of the lower lip, sometimes using an oral screen. Two primary-dentition cases with lip sucking and lip biting were treated with a functional appliance (F.A.), resulting in the elimination of the habits in 5 to 6 months along with the improvement of the overjet, overbite and facial profile. The authors prioritize myofunctional therapy (MFT) when treating open bite cases with tongue thrust in the primary dentition. However, the treatment of maxillary protrusion due to lip sucking and lip biting is approached differently with priority given to morphological improvement to create an oral environment that makes lip sucking and lip biting difficult, which is complimented with lip exercises and habituation. This combined approach was found to be effective in breaking the lip-sucking and lip-biting habits.

Objective: A study was designed to determine changes in the amplitude of the EMG muscular activity of the Masseter and Temporalis muscles at clench in children with a Class II, division 1 malocclusion treated with the pre-orthodontic Trainer functional appliance, for 12 months. Study Design: 36 Class II, division 1 malocclusion patients (mean age 7.6 ± 1.3 years) composed the treated group and wore the functional appliance; 22 children with a similar age and malocclusion composed the untreated controls; and, 20 children with no dental malocclusion participated as normal controls. Electromyographic (EMG) muscular activity of the Temporalis and Masseter muscles were recorded before and after treatment. Results: Subjects in the treated group reported a bilateral significant increase in the muscular electrical activity in the both tested muscles (p < 0.001). After treatment, they recorded values similar to those measured in normal controls, whereas the untreated controls remained on lower values. Conclusion: These results confirm that treatment with the pre-orthodontic Trainer functional appliance significantly increases the EMG muscular activity in the Temporalis and Masseter muscles at clench in patients with Class II, division 1 malocclusion.
