“…From the results of this paper we can state that a good occlusion is very important to maintain the stability of the kinetic chain of the body. Particularly, as we already showed, the position of premolars plays an important role in the stability of occlusion [36], and early orthodontic treatment could prevent the development of complex malocclusions, especially cross-bites [34,[37][38][39][40][41].…”

The aim of this study was to investigate the possible relationship between malocclusion and body posture anomalies. The original sample involved 127 children (45 males and 82 females) with mixed dentition. Clinical examination of oral cavity was performed by an orthodontist, who recorded molar and canine relationship, cross-bite, lower middle-line deviation, and centric relation (CR) considering mono or bilateral contacts in CR. Orthopedic examination of the body posture was clinically carried out by an orthopedist who detected anomalies such as scoliosis, false scoliosis or paramorphism, kyphosis and lordosis. Of the 127 subjects of the sample, 18 children were orthopedically normal, 80 patients had false scoliosis, 22 scoliosis and 7 showed kyphosis. In our study, we don’t consider the 7 patients with kyphosis for the exiguity of the sample; so, our analysis was performed on 120 children (42 males and 78 females). The results obtained revealed that the cross-bite was more frequent when scoliosis became worse. We also found that the relationship between left cross-bite and contralateral side of deviation of the curve of the spine in subjects with scoliosis is statistically significant (p = 0.002). Furthermore, the relationship between lower midline and contralateral side of deviation of the curve of the spine in patients with false scoliosis is statistically significant (p = 0.003). In conclusion, it seems that posture anomalies are correlated to cross-bite and mandible abnormal position.

“…Different kinds of malocclusions can be corrected with different approaches and appliances, but in some cases, it is necessary to extract healthy teeth in order to reduce the convexity, and this is extractive therapy [7,8]. In young patients with a dolichofacial pattern, cervical headgear is the best approach to correct the class II malocclusion by orthopedic maxillary alteration, with a superb control of the vertical dimension [13]. In very difficult cases, in which the skeletal discrepancy is too much, or in protocol surgery first [14], the condition could be solved with orthognatic surgery which allows us to treat severe conditions [15][16][17]; but surgery exposes the patients to risks [18][19][20].…”

Elastics are the simplest device that can be used during a class correction in orthodontics, and despite the simplicity of a latex band, they are very effective and powerful. The resultant inter-maxillary force affects not only the teeth, but even the mandibular position, and consequently the temporomandibular joints (TMJ). The purpose of our work is to simplify the use of elastics, and to reduce the amount of inventory for orthodontists, because there is a lot of merceology available on the market, and different ways of using the elastics. The use of elastics in clinical practice is based on the force extension values, which are given by the manufacturer for the different sizes of the elastics, generally when they are stretched to three times their lumen size. Various configurations allow for the correction of different malocclusions. We propose a new classification and a new device, the elastic selector gauge, in order to allow clinicians to quickly and easily choose the right elastic in all conditions.

“…The outcome of this study could be different if the groups were treated in different growth stages. However, it is noteworthy that in many studies on CH treatment, the initiation of treatment has been done between 8.5 and 10.5 years, before or during the initiation of the second mixed dentition (4,5,11,12).…”

“…For this reason, the use of CH is not recommended in patients with vertical growth pattern, even though there are reports where the use of CH with vertical growth pattern did not worsen the posterior growth (11). On the contrary, anterior rotation of the mandible has been reported (11,12).…”

Summary Background There is a lack of evidence based on longitudinal information in the field of Class II malocclusion management with cervical headgear (CH), especially in a randomized setting. Objectives The main objective of this study was to evaluate skeletal facial changes, particularly in vertical dimensions, after Kloehn-type CH treatment in children when the timing of treatment is altered. Trial design Prospective, parallel-group, randomized controlled trial. Methods Screened children with Class II malocclusion were randomized in 1:1 ratio to two groups of equal size by sealed-envelope randomization: the early group (EG), where active CH treatment was started at the age of 7.8 years, and the late group (LG), where CH treatment was started at the age of 9.5 years. The active treatment was continued until normal Class I occlusion on first molars was achieved. Cephalograms were taken at three different time points. Changes in cephalometric measurements were compared between groups and genders. Blinding was applicable for outcome evaluation. Results Of 67 randomized children, 56 completed the study. Upper face height increased during the CH treatment phase, as the parameter N–ANS increased significantly during the active treatments of EG (P < 0.05) and LG (P < 0.05). Also, the parameter NSL–PL increased significantly during the treatment of EG (P < 0.01) and during the treatment of LG (P < 0.01). The Gonial angle decreased significantly in the early CH treatment group compared to the later treatment group (T0–T2: P < 0.01). CH improved the antero-posterior jaw relationship. No harms were encountered. Conclusions Although the upper face height increased, the mandible showed anterior rotation after CH treatment. The Gonial angle was significantly decreased in the EG compared to the LG. There were gender-specific differences in both sagittal and vertical dimensions when examining interrelations in dimensional changes. The differences found between the early and later treatment groups were not clinically important when the cephalometric results are considered. Clinical registration ClinicalTrials.gov (NCT02010346).
