This paper reports a Class II, division 2 malocclusion case successfully treated at an early age and in a relatively short period of time using the Trainer for Kids (T4K), a prefabricated functional appliance. Skeletal changes observed in the before and after treatment cephalic radiographs were compared with the expected changes produced by the patient's natural growth. The functional appliance's effects resulting in the outcomes observed in this clinical case, as well as the importance of identifying the etiological factors when treating a malocclusion will be discussed.

The purpose of this study was to determine the effect of the T4K, a prefabricated functional appliance, on the transverse and anterior-height dimensions of the maxillary and mandibular dental arches. Dimensions before and after treatment were measured on the sample, then, natural growth was subtracted from the treatment effects and compared with twice the error of the method. A clinically significant increase of both dimensions was observed in the maxilla and mandible when Class II malocclusion patients were treated with the T4K. Therefore, this retrospective study demonstrates that T4K is a valid treatment choice at an early age when transverse expansion is part of the treatment goal.

Background. Inheritance is most casual etiological factor of Class II division 2 malocclusion. This kind of malocclusion is very difficult for treatment specially in older patients. Case report. In the female patient, 20 years old, at the beginning of the treatment at the School of Dentistry in Belgrade, lateral cephalogram showed skeletal and dentoalveolar Class II division 2 malocclusion. She was in the Herbst treatment for 8 months and 12 months more with a fixed multibracket appliance. The measurements were performed on lateral cephalograms before and after the treatment: ii, is, mi, ms, Pg and ss. The distance from these points to occlusal perpendicular line (Olp) were measured and compared from cephalogram before to cephalogram after the treatment. Temporomandibular joint (TMJ) tomograms were compared from before and after the treatment by superimposition. Correction was found in molar and incisor relation, overjet and overbite. There were found sagital skeletal changes and soft tissue profile improvement. Conclusion. Herbst appliance is effective in the treatment of Class II malocclusions, even in adult patients. Dental and skeletal changes as a result of Herbst treatment could be good choice instead of camouflage orthodontics or surgical decision.

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.

The Alt-RAMEC protocol was introduced by Liou in the year 2005. It allows for sutural mobilisation by opening and closing the RME screw for 7-9 weeks. Maxillary protraction after the use of Alt-Ramec (alternate rapid maxillary expansion and contraction) protocol is an efficient method for early treatment of skeletal Class III malocclusion. This case report shows the results of using a hyrax bonded maxillary expander with the Alt-RAMEC protocol to treat a maxillary hypoplasia Class III malocclusion. A 12-year-old patient with skeletal class III malocclusion with anterior as well as the unilateral posterior crossbite was treated using this protocol. CBCT scans were taken before and after expansion. These CBCT scans were used for assessing and analysing the skeletal changes that have occurred after using the AltRamec protocol. The objective of this case report is to assess skeletal changes after using the Alt-RAMEC protocol.

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.
