“Spontaneous” correction capacity of skeletal Class II malocclusions in growing patients after upper and lower arch coordination using fixed appliances: A prospective controlled clinical study
ConclusionsUpper and lower arch coordination alone does not seem to affect mandibular growth; however, because of a posterior rotation of the mandible, it does affect the direction of mandibular growth in some patients, although not in the desired therapeutic direction.

Interleukin 17 (IL-17) and interleukin 23 (IL-23) levels are modulated by compressive orthodontic forces in humans
ConclusionUpregulation of IL-17 and IL-23 occurred in response to the force application in compression sites. Monitoring the levels of inflammatory mediators might be a clinically useful procedure, as they may help to define optimal forces to produce the most rapid tooth movement.

An updated systematic review regarding early Class II malocclusion correction
ConclusionsFrom the short-term perspective, there is a high level of evidence that early treatment reduces overjet and improves the anterior-posterior skeletal relationship. There is insufficient evidence about whether early treatment can reduce the incidence of trauma, is cost-effective, provides improved soft tissue profile, improves oral health–related quality of life, or possesses a risk of developing TMD.

Patient perceptions and oral impacts following labial and lingual biocreative therapy: A randomized clinical trial
ConclusionsOral impacts are commonly experienced during both labial and lingual biocreative therapies. No statistically significant differences were found between the two groups regarding functional limitation, physical pain, and adverse effects on quality of life. Patients treated with labial biocreative therapy were more annoyed by the appearance of the appliance and were more likely to be embarrassed compared with those treated by the lingual biocreative technique. Both groups had similar levels of treatment satisfaction. (Source: Journal of the World Federation of Orthodontists)

Evaluation and comparison of bracket slot dimensions in lingual bracket systems: An in vitro study
ConclusionsActual slot size and shape of commercially available brackets are larger or smaller from the actual prescribed value within a bracket series. Slot geometry and the standard of bracket finish varies between the brackets of different groups. Clinicians should be aware that there may be a three-dimensional loss of tooth positioning as a result of the inadvertent use of orthodontic brackets with oversized slots prolonging treatment duration and the need of additional wire bending to overcome the inadequacies of the brackets so as to achieve a good finishing.

3D-CT assessment of mandibular widths in young subjects with different underlying vertical facial patterns
ConclusionsDolichofacials are likely to have relatively smaller masseter cross-sectional areas and volumes than brachyfacials, and vice versa. There is likely to be a close association between mandibular intermolar width and the corresponding widths at the apical and lower border levels. There is not likely to be the same association between the intercanine width and the corresponding lower border width. Brachyfacials are likely to have a greater width of buccal cancellous bone through which the canines can potentially be expanded laterally. (Source: Journal of the World Federation of Orthodontists)

Perception of facial profile changes after treatment with Forsus fatigue-resistant device in Class II patients
ConclusionsOrthodontic treatment performed with the Forsus fatigue resistance device combined with fixed orthodontics had a positive outcome according to orthodontists and patients. The better attractive profile rates scored by patients may suggest a higher acceptance of the Class II facial characteristics. These data may guide orthodontists to discuss the treatment goals with patients considering their expectations and esthetic perceptions. (Source: Journal of the World Federation of Orthodontists)

Biphasic sutural response is key to palatal expansion
ConclusionTransverse force stimulates two distinct phases in the mid-palatal suture. An early catabolic phase, characterized by inflammation, osteoclast recruitment, and activity, results in bone resorption and sutural widening. Then osteoclasts activate osteoblasts resulting in an anabolic phase, during which the integrity of the skeleton is reestablished. (Source: Journal of the World Federation of Orthodontists)

Rotational effects of Class II Division 1 treatment with the Herbst appliance and fixed appliances in growing subjects with different vertical patterns
ConclusionThe results support previous reports that combined Herbst and fixed appliance treatment is likely to be associated with considerable Class II dental correction in many cases. Although there is likely to be a wide range of individual response to the use of the Herbst appliance, it is unlikely that such overall treatment will be associated with clinically significant forward mandibular rotation in dolichofacial subjects.

Orthodontic retention procedures in New Zealand: A survey to benefit clinical practice guideline development
ConclusionsA trend toward more dual retention instead of solitary removable or solitary fixed retention, more vacuum-formed retainers instead of Hawley-type retainers and more life-long retention instead of retention for a definite period of time has been demonstrated. For all dental professionals in New Zealand and worldwide, it is necessary to be familiar with unintentionally active retainers and be able to identify them. This can prevent the worsening of inadvertent tooth movements. (Source: Journal of the World Federation of Orthodontists)
