Distal Occlusion

Dental anomalies are the leading ones among dental diseases in the period of mixed (79,96%) and permanent (84,33%) dentition. According to the results of our studies, frequency of distal occlusion (up to 40%) and dental crowding (up to 65%) are the largest in structure of orthodontic pathology. The aim of the study is to analyze and summarize knowledge about ways of enhancement of treatment and prophylaxis efficiency in patients with distal occlusion and dental crowding. Genetic predisposition, early childhood diseases (including upper respiratory tract infections), children's bad habits, pathological state of teeth (adentia, impaction, micro-, macrodentia), micro-, macrognathia, functional disorders of maxillofacial area contribute a high percentage in structure of "risk factors" which lead to formation of distal occlusion with dental crowding. For each particular patient distal occlusion, complicated by dental crowding, is formed under the influence of combination of several "risk factors", where the first place belongs to disturbances of dental area: breathing, closing of lips, swallowing, chewing, speech. Today it is well known that the first step in correction of distal occlusion of dentitions is to evaluate the patient's potential growth. Treatment in the period of mixed dentition is important with relation to protection of palate from trauma by mandibular incisors with a large sagittal gap, prophylaxis of dysfunction of temporomandibular joint, psychological rehabilitation of children during speech formation, as well as to improve the prognosis of treatment in older age. The best period of treatment is a peak of growth and development. Growth is the most important factor in planning treatment of distal occlusion, since dramatic changes in correction are related to growth rather than teeth movement. Orthodontists forbear from recommendations for teeth extraction in growing patients, as they believe that it leads to worsening of face profile and does not allow to achieve optimal relationships of jaw and occlusion. In adult patients, complete conservative correction of distal occlusion is possible only in the absence of skeletal disorders. Combined method, namely combination of orthodontic treatment and orthognathic surgery, is an alternative for adults treatment. Adequate individual approach to orthodontic treatment in patients with distal occlusion complicated by dental crowding is based on a comprehensive clinical examination, scientific analysis and results interpretation of additional examination methods. Full functional occlusion is possible if all elements of dentition: occlusion, periodontal tissues, temporomandibular joints, muscles and nervous system, are considered. Stable results and positive prognosis are provided by normalization of physiological state of masticatory and mimic muscles.

Crevicular Fluid

Background: The crevicular fluid analysis represents a useful diagnosis tool, with the help of which noninvasive cellular metabolic activity can be analyzed. The aim of the study is to investigate comparatively IL1β and IL6 in the gingival crevicular fluid of clinically healthy adolescents and young adults during the acute phase of orthodontic treatment. Methods: Gingival crevicular fluid was collected from 20 patients (aged between 11 and 28) undergoing orthodontic treatment. Measurements were taken before (T0) and after 24 h after distalization forces were activated (T1). IL1β and IL 6 were analyzed using Elisa tests. The statistical tests used were two-sided t tests. Results: Between the two time periods there was a significant raise both in the crevicular fluid rate (0.57 µL at T0 vs. 0.95 µL at T1, p = 0.001) and in IL1β levels (15.67 pg/µL at T0 vs. 27.94 pg/µL at T1, p = 0.009). We were able to identify IL6 only in a third of the sites. There is a significantly increased level of ILβ at T1 in adolescents, more than in young adults (42.96 pg/µL vs. 17.93 pg/µL, p = 0.006). Conclusions: In the early stage of orthodontic treatment, the periodontal tissues of adolescents are more responsive to orthodontic forces than those of young adults.

Aim: To evaluate the periodontal status before and after orthodontic treatment and to analyze the confounding factors associated with it. Materials and Methods: The present retrospective study analyzed pre- and posttreatment records of a total of 60 patients. Intraoral digital photographs before and after the orthodontic treatment were used to measure the following three periodontal variables: (a) width of the keratinized gingiva, (b) gingival recession, and (c) the status of interdental papilla. The ImageJ 46 software imaging program was used to perform the required measurements. The clinical data were then analyzed in an association with the participants’ demographic data, the type of orthodontic tooth movement, and other confounding factors. The data obtained were manually entered into the statistical package and analyzed using a significance level set at P < .05. Descriptive statistics, paired t-tests, and Pearson’s correlation analysis were used to identify differences among the studied variables. Results: Among the 60 patients, the majority (66.7%) were females. Most cases of the treated malocclusion were Class II, and most patients underwent intrusion and retrusion movements. The width of keratinized gingiva increased for most sites of upper teeth. In contrast, the lower teeth showed a mix of improvement and compromised width of keratinized gingiva. As a measure of gingival recession, the difference of clinical crown height revealed the tendency toward a reduced clinical crown height for most sites. Upper left lateral incisors and canines showed significant values with regard to keratinized gingival width measurements and tooth movements such as extrusion and intrusion movements. Likewise, with regard to the clinical crown height, upper right central incisors showed significant differences when correlated with the interincisal angle, lower incisors to the mandibular plane, and upper incisors to the NA line. The upper lateral incisors also showed significant correlations to certain cephalometric measurements. Conclusions: The orthodontic treatment was found to exert a significantly positive impact on the surrounding periodontium, particularly in the upper canine areas. Likewise, various types of tooth movement were found to positively affect the periodontium.

The article presents the results of clinical and microbiological studies and immunological features of the state of periodontal tissues in patients with moderate periodontitis, which developed as a complication of orthodontic treatment. It was found that at the later stages of orthodontic treatment with the development of periodontitis, a complex of persistent changes in the periodontal tissues at different levels of pathogen-esis was revealed in patients. In this connection, in order to plan the complex treatment of patients with periodontitis, which has developed as a complication of orthodontic treatment, and to predict the course of the disease, it is necessary to influence the established and mutually supportive links and indicators of pathogenesis.

Introduction: During orthodontic tooth movement, the early response of periodontal tissues to mechanical stress is an acute inflammatory reaction. Mechanical stress from orthodontic appliances is believed to induce cells in the periodontal ligament (PDL) to form biologically active substances, such as enzymes and cytokines, responsible for connective tissue remodeling (Nishijima Y et al 2006). Leptin, a polypeptide hormone has been classified as a cytokine (Zhang et al 1994). Earlier findings concluded that leptin at high local concentrations protects the host from inflammation and infection as well as maintaining bone levels. It has been also suggested that leptin plays a significant role in bone formation by its direct effect on osteoblasts (Alparslan et al 2010). This pilot study aimed to study leptin in saliva and its association with tooth movement during initial orthodontic alignment. Objectives: To determine if there are any differences in saliva leptin level before and after orthodontic alignment. Material and methods: Ten orthodontic patients (7 girls and 3 boys; mean age, 16.76 ± 1.1 years) with crowding (up to 5mm) that required orthodontic fixed appliances, on a non-extraction basis as part of the treatment plan, were recruited in this longitudinal study. Orthodontic study models were constructed at baseline and at 6- weeks after orthodontic treatment commenced. Full fixed orthodontic appliances with initial 0.014” Nickel Titanium archwire placed. The amount of crowding was measured, before and after initial alignment with an electronic digital caliper (Max-Cal, Japan Micrometer Ltd, Tokyo, Japan) with an accuracy of up to 0.01mm. Unstimulated morning saliva sample were collected at all visits, after at least an 8-hour period of fasting and no-toothbrushing. After centrifugation (4000x g;10min), the samples were stored at -25C and tested using Leptin Abnova LEP Human ELISA kit (KA3080) which was subsequently analyzed. Subjects’ periodontal health status was also monitored throughout the study. Ethical approval (ID IREC 262) was received on 7th April 2014 from International Islamic University Malaysia Research Ethics Committee (IREC). Results: Leptin concentration in saliva was significantly decreased in a time-dependant manner (t(9)=8.60, p<0.001), from before orthodontic treatment (7016.45± 425.15 pg/mL) and 6 weeks after bond-up (4901.92±  238.64 pg/mL). Conclusion: Leptin concentration in saliva is decreased during orthodontic tooth movement in initial alignment stage.

Background and aim. Orthodontic tooth movement (OTM) is a process whereby the application of a force induces bone resorption on the pressure side and bone apposition on the tension side of the lamina dura. However, only limited data are available on the in vivo behavior of the periodontal tissues. The aim of this study was to assess the changes of periodontal tissues, induced by the orthodontic canine retraction, using 40 MHz ultrasonography.Methods. Ultrasonographic evaluation of periodontal tissues was conducted in 5 patients with indication for orthodontic treatment. The upper first premolars were extracted bilaterally due to severe crowding, and the canines were distalized using elastomeric chain with a net force of 100 cN. Ultrasonographic scans (US scans) were performed before, during and after retraction, in three distinct areas of the canines buccal surface: mesial, middle and distal. The reference point was the bracket, which appeared hyperechoic on the US scan. Four different dimensions were obtained: D1 (depth of the sulcus), D2 (thickness of the gingiva), D3 (length of the supracrestal fibers), D4 (width of periodontal space).Results. An increase of D1 was observed in all three areas of the periodontium, during orthodontic treatment.  D3 was strongly correlated before and immediately after force delivery only for the mesial area (r=0.828, p<0.05). In total, 228 variables were statistically analyzed using Pearson’s correlation coefficients, in order to demonstrate the relationship between periodontal findings during orthodontic tooth movement.Conclusions. High-resolution ultrasonography has the capability to obviate changes in periodontal ligament space and free gingiva during orthodontic tooth movement.

Aim. To analyze the results of orthodontic treatment of a child with asymmetrical micrognathia and mandiblar condylar hyperplasia. Methods. The configuration of a face in the photos was evaluated and diagnostic models of the jaws were analyzed by using the Ponts and Korkhaus methods in treatment dynamics. The physiological status of bone tissue, temporomandibular joints and teeth was studied by using orthopantomography and computed tomography. Functional disorders were detected by using special tests, including EschlerBittner's test and Ilyina-Markosyans test. Orthodontic treatment and stimulation of mandibular growth in the mixed dentition stage were undertaken with the single jaw removable appliances and the appliance improved by us for correction of the distal occlusion. The Damon Q bracket system with archwires was used in permanent dentition period. Results. The child's convex facial profile was typical for distal occlusion and micrognathia. The facial asymmetry, increasing with mouth opening, and a decrease in mandibular range of motion indicated lesion of the right temporomandibular joint. The right condyle was enlarged on the orthopantomogram. The computed tomography showed that it was asymmetrically enlarged and had a cellular structure. There was detected asymmetric micrognathia. The comprehensive rehabilitation plan included orthodontic treatment, myotherapy, speech therapy, mechanotherapy. The use of removable orthodontic appliances led to the normal size of the dentition and their relation, significantly reduced functional disorders and improved facial aesthetics. Five years after completion of orthodontic treatment, the physiological occlusion and amplitude of the mandibular movements remained, but the right mandibular angle was flattened. Conclusion. The comprehensive rehabilitation of a child with asymmetrical micrognathia and mandibular condylar hyperplasia started in mixed dentition stage provided conditions for the formation of normal permanent dentition and the improvement of functional disorders and facial aesthetics; our results allow us to suggest the positive effect of our tactics for treatment of the patient.
