The aim of the study. Improving the effectiveness of the diagnosis of maxillomandibular anomalies among the patients with pathological occlusion, existing bad habits is relevant due to the spread of social stress among young people and the search for its compensation through the development of bad habits. Research methods. We conducted clinical and radiological methods of examination of 60 patients aged 15–17 with acquired maxillomandibular anomalies, deformities, and 15 people in the comparison group. We studied the data of computer tomograms, performed stereotopometric analysis (threedimensional cephalometry), determination of the thickness of the masticatory muscles in symmetrical areas of the face. Patients underwent a secret questionnaire to identify stressors that affected the body, studied the relationship between the presence of stress and the appearance of changes in cephalometric parameters. Scientific novelty. Clinical studies and survey results have shown that 95 % of patients surveyed have bad habits that are associated with chronic social stress. The results of examination of cephalometric analysis and photoprotocol confirm the expressed disproportions of one of the jaws, where there is a oral habit; confirm the presence of acquired rather than congenital deformity of the facial skeleton, which is associated with changes in the thickness of the masticatory muscles on the side of the deformation. Conclusions. Our research has shown that bad habits progress in the presence of chronic social stress, which according to the survey results in 95% of patients. Distance learning is the most important stress factor in most patients surveyed.3D cephalometric analysis should be included in the mandatory methods for the diagnosis of acquired deformities of the maxillofacial area. Clinical and radiological research methods help the orthodontist to identify a whole range of interrelated etiological factors in the development of dental anomalies and acquired deformities of the maxillofacial area and make a correct plan of complex treatment. Key words: Stress, Sleeping Habits, Tongue Habits, Cephalometry, Face, Orthodontic, Deformities.

The aim of the study. Improving the effectiveness of the complex treatment of maxillomandibular anomalies and oral habits. Research methods. The cross-sectional study involved 15 relatively healthy children and 60 children with acquired maxillomandibular anomalies and oral habits aged 15-17 years. A clinical examination was conducted. There was an extaoral examination, determination of the way of swallowing and breathing, determination of the condition of the temporomandibular joints, a photo protocol. The patients were given a secret questionnaire in order to identify stress factors that affect the body. The relationship between the presence of a stress factor and the appearance of changes in the maxillofacial area was studied. The cephalometric study was evaluated before and after complex treatment. We have compared the cephalometric study with the results of the clinical examination. Scientific novelty. The obtained results of secret survey, the STAI testify to the state of chronic tension of patients, a feeling of emotional relief during the period of using an oral habit. The results of the examination and photo protocol confirm pronounced changes in the symmetry and proportionality of the face in the area where was an oral habit associated with recorded extratonic reflexes. Patients had complex treatment with non-removable palatal structures, brace systems in combination with myogymnastics. The treatment was supplemented with myofunctional appliances, if there were functional disorders, in particular the act of swallowing or hidden mouth breathing. The results of the cephalometric study confirm the presence of adaptive changes on the part of the jaw bones and the muscular system and confirm the existence of a functional facial matrix. Conclusions. The etiopathogenetic approach to the complex treatment of orthodontic patients helps to achieve the desired therapeutic effect and prevent relapses. The long-term results of the treatment indicate that after the treatment, the clinical and cephalometric characteristics of the jaw bones and the muscular apparatus normalize in patients. Key words: stress, oral habits, maxillofacial deformations, cephalometry, myofunctional aplliance.

The aim of the study. Increasing the effectiveness of complex treatment of patients with a pathological bite through orthodontic treatment, impact on masticatory and facial muscles, conscious elimination of oral habits. Research methods. 30 people aged 9–12 years with acquired maxillomandibular anomalies against the background of oral habits and 15 people of the comparison group were examined and treated. Group I patients (15 people) had orthodontic treatment and elimination of oral habits, and group II patients (15 people) received treatment supplemented with myofunctional devices and myogymnastics. We studied the results of computer tomograms, performed stereotopometric analysis (threedimensional cephalometry), and determined the thickness of the masticatory muscles in symmetrical areas of the face. Secret questionnaires were administered to patients in order to identify stress factors that affect the body, and the relationship between the presence of a stress factor and the appearance of changes in cephalometric indicators was determined. The study was conducted before treatment, after 6 months and after 12 months after the start of active orthodontic treatment. Scientific novelty. Clinical studies have shown that all patients have oral habits that lead to changes in the maxillofacial system. The results of the questionnaire showed that 96.6 % of the examined patients associate them with the presence of stressful factors.The results of the examination, cephalometric analysis and photo report confirm the presence of pronounced disproportions from one jaw or symmetrical parts of the face, shortening of the lower third of the face; prove the presence of an acquired rather than congenital deformation of the facial skeleton, which is combined with a change in the thickness of the masticatory muscles on the side of the deformation. The results of the comparative analysis after 6 and 12 months indicate a more pronounced positive trend towards the normalization of clinical indicators and data of cephalometric analysis in patients of the II group. Conclusions. Oral habits are directly proportional to stress factors, which, according to the results of the examination, are present in 96.6 % of all patients. 3D cephalometric analysis should be included in the mandatory methods of diagnosis of acquired deformities of the maxillofacial area before and at the stages of complex treatment. The results of clinical, x-ray research methods and cephalometric analysis indicate the need to use devices that correct the work of the muscular apparatus and myogymnastics in the complex treatment of patients with maxillomandibular anomalies on the background of oral habits. Key words: oral habits, cephalometric analysis, orthodontic treatment, myofunctional devices, myogymnastics.

OBJECTIVE: This pilot study investigated the morphological and functional aspects of an English horn player, who presented at a dental appointment with temporomandibular disorder (TMD), using the “combined acquisition method of image and signal technique” (CAMIST) in the diagnosis. METHODS: Cephalometric analysis was obtained after carrying out three lateral cephalograms using a standardized radiographic technique. The first one was taken with the teeth in the normal occlusion and the lips relaxed, the second with the oboe embouchure, and the last was performed with the English horn. To understand the pressures involved during the embouchure and musical performance of the English horn and oboe, a system was developed using force sensors placed on the double-reed mouthpiece. Finally, infrared imaging was used to better understand the anatomy-physiology of specific structures of the cranio-cervico-mandibular complex. RESULTS: Cephalometry of the musician showed more significant changes in the retrusion of the mandibular pogonion. The embouchure pressures measured during musical practice showed that the English horn induced a higher pressure on the lower lip than on the upper, while the inverse happened with the oboe. Thermography confirmed the painful site on the left temporomandibular joint (TMJ), and this was also observed in the muscle tenderness/discomfort on the right superficial masseter by the differential temperature of these areas. CONCLUSION: Techniques such as lateral teleradiography, infrared imaging, and force sensors can be useful screening tools with added value for the diagnosis of TMDs in performing artists.

Objective. To describe modification of the originally described genioglossus muscle advancement and its clinical assessment in the treatment of patients with obstructive sleep apnea. Study Design. Prospective study. Setting. University medical hospital. Subjects and Methods. Twenty-three patients with obstructive sleep apnea underwent modified genioglossus muscle advancement with uvulopalatopharyngoplasty. All patients were evaluated before and 6 months after surgery by history taking, clinical examination, Epworth Sleepiness Scale evaluation, fiber-optic nasopharyngoscopy, cephalometry, panoramic X-ray, and nocturnal polysomnography. Results. Postoperative mean ± SD apnea-hypopnea index (AHI) decreased from 40.7 ± 17.4 to 15.4 ± 10.7 ( P = .00; 95% confidence interval [CI], 18.4 to 32.27). With a success rate defined as AHI <20 and a 50% decrease in AHI of the preoperative value, the surgical success rate was 86.9%. Cephalometry analysis showed a significant difference between preoperative and postoperative findings, including a posterior airway space that increased a mean ± SD from 8.1 ± 2.5 to 12.3 ± 3.7 mm ( P = .00; 95% CI, −5.89 to −3.0), position of the mandible to the cranial base (SNB degree) that increased from 77.3 ± 2.7 to 78.5 ± 1.3 ( P = .005; 95% CI, −2.11 to −0.4), and improved palatal parameters. The mean (SD) average depth of the osteotomy and genioglossus advancement was 11.8 ± 2.6 mm. None of the 23 patients had mandible fracture, aesthetic changes of the chin, or detachment of the advanced genioglossus muscle. Conclusion. The modification described in this technique permits complete and safe capture and advancement of the whole genioglossus muscle, leading to satisfactory expansion of the retrolingual airway without stripping, detachment of the advanced genioglossus muscle, mandible fracture, or aesthetic changes of the chin.

Introduction. Aim of the study is testing the algorithm of complex clinical, functional and instrumental analysis in the treatment of patients with the need for total restoration of the dentition with manifestations of myofascial pain syndrome.
Material and methods. A system for the rehabilitation of patients with adentia is proposed, in which, when planning occlusion correction, objective examination data for patients obtained using a set of diagnostic methods should be taken into account. Particular attention is paid to assessing the function of the temporomandibular joint and the presence of pathological signs of disorders of maxillofacial muscles.
Results. A clinical case is described a patient who has been diagnosed with a set of indicators of clinical, functional and instrumental analysis obtained using methods of condylography and cephalometry. The results of treatment and rehabilitation measures allowed achieving the optimal distribution of loads on the dentition, while reducing the risk of ceramic chipping and improving oral hygiene. The approach used allowed timely correction of functional and aesthetic disorders.
Conclusions. The algorithm for working with patients who need total restoration of the dentition should include a thorough history taking, clinical functional analysis using condylography methods, model analysis to register and evaluate the static and dynamic ratios of the dentition. As well as performing cephalometric analysis and other manipulations, in accordance with standard criteria for clinical examination. The developed algorithm is anatomically and pathogenetically justified, since it takes into account the entirety of changes and interconnections of the structures of the dentofacial system and other body systems that underlie the clinical manifestations in this category of patients.

The purpose of this meta-analysis is to compare clinical screening tests for obstructive sleep apnea and establish an evidence base for their preoperative use. Diagnostic odds ratios were used as summary measures of accuracy, and false-negative rates were used as measures of missed diagnosis with each screening test in this review. Metaregression revealed that clinical models, logarithmic equations, combined techniques, cephalometry, and morphometry are significant characteristics, whereas body mass index, history of hypertension, and nocturnal choking are significant test elements associated with higher diagnostic accuracy. Test accuracy in repeated validation studies of the same screening test is variable, suggesting an underlying heterogeneity in either the clinical presentation of obstructive sleep apnea or the measured clinical elements of these models. Based on the false-negative rates, it is likely that most of the clinical screening tests will miss a significant proportion of patients with obstructive sleep apnea.

The aim of the present investigation was to evaluate the craniofacial features of subjects with normal occlusion with different vertical patterns in the mixed dentition using morphometric analysis (Thin-Plate Spline analysis - TPS) applied to posteroanterior (PA) films. The sample comprised 39 individuals (18 females and 21 males), all in mixed dentition, aged from 8.4 to 10 years with satisfactory occlusion and balanced profile and with no history of orthodontic or facial orthopedic treatment. The sample was divided into three groups (mesofacial, brachyfacial and dolichofacial) according to the facial types proposed by Ricketts (1989). The average craniofacial configurations of each study group were obtained by orthogonal superimposition of Procrustes, thereby eliminating size differences and allowing only shape differences between groups to be analyzed by viewing the TPS deformation grid. Significant differences were found among the three facial types but were more remarkable between mesofacials and dolichofacials than between mesofacials and brachyfacials. TPS morphometric analysis proved efficient for accurate visualization of transverse and vertical differences among facial types even before pubertal growth spurt. These differences cannot be easily detected by traditional posteroanterior cephalometry.

Introduction: Open bite malocclusion is one of the most difficult dentofacial deformities to treat. Although this type of malocclusion can occur unilaterally or bilaterally in the buccal segments. It is mostly seen in the anterior segment where there is no incisal contact and vertical overlap of the lower incisors by the uppers. Objectives: The study was aimed to find out the incidence of open bite malocclusion and their pre and post treatment evaluation of the treated cases and also compare the result of two study groups (skeletal open bite and dental open bite). Methods: A total number of 31 patients with open bite malocclusion out of 1372 patients reported to Department of Orthodontics, Dhaka Dental College and Hospital for treatment. Out of them 21 patients were included in this study with mean age 22±5.4, who successfully completed treatment. Of them 14 were included in the dental group and 07 in the skeletal group. Pre treatment history, clinical examination along with pre and post-treatment photographs, study models and lateral cephalograms were used to compare the treatment outcome between the two study groups. Results: The incidence of open bite was 2.3%. Out of 21 open bite samples 14 were of dental type and the rest 07 were of skeletal type. 47.6% open bite had Angles Class I malocclusion, 42.9% were Class II and 9.5% were Class III. Cephalometric analysis of vertical measurements showed that the mandibular plane angle, palatal plane angle and SNA angle significantly decreased from pre-treatment to post-treatment (p<0.05) in both groups . Gonial angle remains unchanged. Cephalometric analysis of the linear and dental measurements showed increased upper face height, posterior facial height and inter-incisal angle. Soft tissue evaluation on cephalometry showed significant decrease of esthetic plane and interlabial gap. A statistically significant mean difference was found in case of negative overbites among the patients with dental group (p<0.001). Less time was required for completion of treatment in dental group and prognosis was significantly better (p<0.05) Conclusion: The result of the present study indicates that the treatment period and wear time of appliance in dental type was shorter than skeletal type. Both groups showed significant improvement though prognosis was better in dental type of open bite cases.DOI: http://dx.doi.org/10.3329/bjodfo.v2i2.16156 Ban J Orthod & Dentofac Orthop, April 2012; Vol-2, No.2, 1-7
