The correction of rotated malpositioned tooth/teeth into the dental arch alignment in the mixed-dentition is often a challenging task for paediatric dentists. Failure in addressing this issue can bring about detrimental effect to the developing dentition and increases the probability of a complex orthodontic treatment in later years. Factors such as severity of the malpositioned teeth, patient’s treatment compliance, limitation in specific functions of the selected appliance, availability of bone and space may dictate the success of the treatment. The combined use of a simple sectional orthodontic wire appliance and a 2×4 orthodontic appliance has been shown to produce a positive effect. The appliances resulted in derotation of the rotated malpositioned teeth and bringing them into arch alignment in two cases. This treatment option had eliminated the detrimental effects to the developing dentition and helped patients to enhance their smile and dental aesthetics.

Anterior crossbite is relatively a common presentation in the mixed dentition stage. If left untreated, it can lead to a host of problems and may complicate future orthodontic treatment. One of the major difficulties in performing anterior crossbite correction in young children is treatment compliance. In most cases, poor compliance is due to the unacceptability of the removable appliance used. This article describes three cases of successful correction of anterior crossbite of patients in mixed dentition using short-span wire-fixed orthodontic appliances. This sectional appliance provides an alternative method of correcting anterior crossbite of dental origin and offers many advantages compared to the use of removable appliances.

Abstract Background : Treatment compliance plays fundamental roles in achieving the best results in orthodontic treatment. Some psychological characteristics such as general self-efficacy (GSE) are correlated with the level of tolerance of individuals. This study aimed to assess the correlation of psychological characteristics such as GSE and level of malocclusion with compliance of removable orthodontic appliances. Methods : The Index of Orthodontic Treatment Need (IOTN) of 50 patients between 10-12 years who required removable orthodontic appliances was determined prior to the onset of treatment. They were also requested to fill out the GSE scale (GSES). The removable orthodontic appliance compliance questionnaire was also filled out by patients at 1 (T1), 3 (T2), and 6 (T3) months after the delivery of the removable orthodontic appliance. Results : The GSES score had significant correlations with the total score of the compliance questionnaire, and subscale score of satisfaction with the appliance during eating and oral hygiene practice, duration of usage of the appliance, and interest in using it (P<0.05). The IOTN had no significant correlation with the compliance questionnaire. Conclusions: The level of compliance of removal orthodontic appliances by patients can be predicted using the GSES. The IOTN is not efficient for prediction of the compliance level of removal orthodontic appliances by patients.

The purpose of this paper is to demonstrate 4 cases with bi-lateral ectopic mandibular canines and to demonstrate in each case which one of the two canines erupted to a normal position in the dental arch. The canines are observed from Orthopantomograms from 4 children (aged 8-13 years of age) in the mixed dentitions stages. Of these children 2 were males and 2 were females. From each child there was between 3-5 Orthopantomograms. These were observed over 3-4 years period. In each of the 4 cases with bi-lateral ectopia of the mandibular canines the one mandibular canine erupted into a normal position, while the other one declined into a horizontal position during the mixed dentition period. These 4 cases demonstrated that the inclination of the canines were important to observe and diagnose from the initial stage (first ortopantomogram). The cases presented, demonstrated that the unsuccessfully erupted canines ending in a horizontal position, were the canines which inclined slightly more that the contra lateral canine already from the initial stage.

The aim of this study was to investigate the orthodontic force exerted by thermoplastic orthodontic appliances incorporating Eucommiaulmoides in terms of usefulness as the aligner-type orthodontic device. Erkodur, Essix C+®, Eucommia elastomer, and edgewise brackets were used (n = 3, each; thickness = 1.0 mm, each). The orthodontic force on the upper right incisor was measured every 24 h for two weeks using a custom-made measuring device. The force of the Eucommia elastomer (4.25 ± 0.274 N) and multi bracket system (5.32 ± 0.338 N) did not change from the beginning to the end (p > 0.01). The orthodontic force exerted by the Eucommia elastomer was lower than that of the multi-bracket orthodontic appliance from the beginning to the end. The force of Erkodur significantly decreased from the beginning to 24 h (6.47 ± 1.40 N) and 48 h (3.30 ± 0.536 N) (p < 0.01). The force of Essix C+® significantly decreased from the beginning (13.2 ± 0.845 N) to 24 h (8.77 ± 0.231 N) (p < 0.01). The thermoplastic orthodontic appliance made of Eucommia elastomer continuously exerted a constant orthodontic force for two weeks under water immersion conditions. The orthodontic force of Eucommia elastomer was found to be similar to the orthodontic force exerted by the multi-bracket orthodontic appliance with 0.019 × 0.025 in nickel–titanium wire. These results suggest that the Eucommia elastomer has possibly become one of the more useful materials to form thermoplastic orthodontic appliance exerting low continues orthodontic force.

Relevance. Deep overbite is one of the most frequent malocclusions in children and teenagers of different ages. Distal occlusion with a deep overbite is the most common (59.6-67.6% according to the literature) in early mixed dentition. Most Russian and international authors state in their research that the severity of malocclusion increases with age. The treatment of the pathology in children is relevant due to deterioration of the deep overbite with age, worsening of functional disorders.Materials and methods. The study analyses the treatment results of a child with a deep bite using the authors’ technique.Results. The study demonstrated the advantages of the authors’ technique. The treatment allowed achieving normal dentoalveolar heights in the posterior mandible on molar and premolar eruption, establishing the correct relationship between the upper and lower dental arches that promoted harmonious development of the child’s maxillofacial area. The treatment regulated the length and width of the upper dental arch and corrected its form. The active intrusion of the lower incisors and extrusion of the lower posterior teeth were observed during the treatment. The curve of Spee was restored, and an increased overlap reduced. Occlusal contacts of posterior teeth improved, and deep overbite decreased. The technique is easy to use and allows curing 9-12-year-old children in a short period (7-10 months).Conclusions. The suggested technique treats deep overbite as well as creates conditions for the further harmonious development of the maxillofacial area. Thus, it can be recommended for the treatment in early mixed dentition.
