Objectives. Orthodontic treatment intends to create a harmony between dental, muscular and osseous components. The purpose of this case presentation was to emphasize consequences of early loss of temporary teeth on dental-maxillary complex development. Material and methods. 10 years old patient with dental movements following the early extraction of temporary teeth. The patient has habitual oral breathing associated with lower lip interposition. Results. The functional treatment with twin-block appliance was chosen, taking into account the age-specific growth potential. Discussions. Premature extraction of temporary teeth engenders lee-way-space loss, significant shortening and transverse constriction of the dental arch, elements aggravated by dysfunctions and parafunctions. Conclusion. The early extractions performed during the growth period, through the associated dental migrations, determine growth changes with consequences on the functionality of the dento-maxillary apparatus.

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.

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.

In a mixed longitudinal study, dental arch relationships of 88 consecutive UCLP patients treated at the Nijmegen Cleft Palate Centre were evaluated using the Goslon Yardstick. On the basis of timing of hard palate closure, the patients were divided into four groups. Mean age of hard palate closure in group A (n = 18) was 1.5 years, in group B (n = 26) 4.6 years and in group C (n = 18) 9.4 years. In group D (n = 26, no patient older than 10 years) the hard palate was still open. Four stages of dental development were distinguished; deciduous dentition, early mixed dentition, late mixed dentition and permanent dentition. Reproducibility of scoring with the Goslon Yardstick was good for all stages of dental development. No differences in dental arch relationships were found between the four groups. In 86% of the cases, the dental arch relationships of UCLP patients treated in Nijmegen were acceptable. Pharyngeal flap surgery had minor unfavorable effects on dental arch relationships.

A review of the dental literature revealed relatively few studies on the expansion of the mandibular dental arch. The present study attempted expansion of the mandibular arch using a Bihelix appliance. The subjects were 16 children, exhibiting crowding, age ranges from 7 to 11 years. The mandible was expanded 2.0 mm every 3 months. Significant expansion, not only of the individual tooth inter-arch dimensions but also of the overall arch length, was obtained during the period of incisor tooth replacement. The mode of expansion was classified as follows: Type I, those, which showed no effect on the apical base; Type II, those which showed no consistency of the measurement lines. In this study, 6 of16 cases were classified as type I and 10 cases as type II. Expansion was continued over a period of 1.5 to 3 years. We concluded that considerable lateral expansion of the mandibular arch is possible using the Bihelix appliance. It is suggested that this might contribute greatly to non-extraction orthodontic treatment. Further studies are recommended.

ABSTRACT Objective:  To evaluate short- and long-term maxillary dental arch dimensional changes in patients treated with a transpalatal arch (TPA) during mixed dentition followed by full fixed appliances in the permanent dentition compared with an untreated sample. Materials and Methods:  Dental casts and lateral cephalograms obtained from 36 consecutively treated patients before TPA treatment (T0), after TPA treatment (T1), after fixed appliance treatment (T2), and a minimum of 3 years after fixed appliance treatment (T3) were analyzed. The control group was matched as closely as possible. Arch widths, perimeter, and length, as well as crowding and incisor proclination, were evaluated. Results:  In the treated group, intercanine, interpremolar, and intermolar widths and arch perimeter increased significantly at T1. At T2, only the intercanine width increase was still significant. At T3 all arch dimensions decreased, remaining larger than they were at T0. The arch length increased after T1, significantly decreased at T2, and slightly decreased at T3. The crowding decreased significantly at T1, was eliminated at T2, and increased at T3. At T3, 50% of the patients showed relapse with crowding ranging from 0.5 to 2 mm. In the control group at T1, only slight changes were noted but crowding increased. At T2, crowding and upper incisor inclination increased but arch length decreased. At T3, intercuspid width, arch perimeter, and arch length continued to decrease, thereby increasing crowding. Conclusion:  Maxillary dental arch dimensions changed significantly after TPA followed by treatment with fixed appliances. Relapse occurred to some extent, especially in intercanine width and arch perimeter, but most of the dental arch changes remained stable.

Time dependent changes of parameters associated with malocclusion in patients with Duchenne muscular dystrophy (DMD) were examined in four dental developmental stages in 34 patients.We adopted activities of daily living (ADL) score, dental arch, craniofacial morphology, and electromyograms of the masseter and temporalis muscle as parameters. A comparison was made with the results in DMD subjects to data from healthy subjects with normal occlusion reported in the literature. In DMD subjects, manifestations of open-bite were related to ADL score, sagittal shortening and transverse expansion of the dental arch and vertical overgrowth of the lower jaw. Posterior cross-bite malocclusion was associated with differences in the time dependent changes between the jaws in transverse expansion. The malocclusion in DMD subjects was also related to the time dependent disproportional changes in masticatory muscle function by EMG. Occlusal deviation in DMD subjects became apparent at the late mixed dentition and malocclusion became definitely manifest from early permanent dentition.

Palmoplantar Hyperkeratosis

Papillon-Lefevre syndrome (PLS) is a rare autosomal recessive disorder characterized by palmoplantar hyperkeratosis and early onset of severe destructive periodontitis causing premature loss of both deciduous and permanent dentitions at a young age. In this article two cases of patients with Papillon-Lefevre syndrome in late mixed dentition are presented. The objective of these case reports was to illustrate that under a controlled regime of periodontal treatment, orthodontic treatment is possible in patients with Papillon-Lefevre syndrome. In both cases, the deciduous dentition was lost prematurely shortly after eruption. The permanent teeth erupt without any guidance, and this can lead to loss of space, crowding, and collapse of the dental arch. The aim of the treatment was to expand the arch, create space to allow normal eruption of the permanent teeth, and stabilize the occlusion to help the patient achieve a normal facial appearance rather than the collapsed appearance caused by early extractions.

Nowadays, it is widely accepted the importance of treating early occlusal abnormalities of clinical significance for the development of the stomatognathic system. An early treatment would restore the harmony and the functionality of the craniofacial complex, it simplifies the corrective procedures, reduces the need for permanent tooth extractions and brings psychological benefits to patients, to name a few. The presence of malocclusions should intervene early to restore proper neural excitation in the craniofacial complex and provide the conditions necessary for each patient to receive their growth potential. The anterior cross bite (MCA) should be treated early to prevent harmful effects on growth and, the development of the maxilla and mandible, to avoid traumatic occlusal forces and restore proper muscle contraction patterns in the patient. This article shows some of the early treatment options for the MCA in primary and mixed dentition after an accurate diagnosis.   Key words: Anterior cross bite, early treatment, class III malocclusion, occlusal plane. Periodontitis, microbiology, transmission, Aggregatibacter actinomycetemcomitans.
