ORTHODONTIC AND ORTHOPEDIC REHABILITATION OF PATIENTS WITH CLEFT OF UPPER LIP, ALVEOLAR SURGERY, HARD AND SOFT PALATE

The problem of children’s rehabilitation with cleft palate is multi edged and complex. The ultimate goal of rehabilitation measures is to restore the anatomical integrity of the tissues of the hard and soft palate, the function of the articulatory and mastication systems, create conditions for correct speech and maximum aesthetic rehabilitation. Orofacial cleft leads to the appearance of functional changes in breathing, sucking, chewing and swallowing. In the process of development of masticatory system, the formation of complex dentoalveolar anomalies in parallel with a significant decrease in masticatory efficiency, weakens the process of sound production, which leads to the formation of stable speech disorders. Such children from childhood form a sense of inferiority, they have reduced social adaptation due to the presence of a cosmetic defect and speech disorders. Optimization of orthodontic and orthopedic rehabilitation of patients with non-incision of the upper lip, alveolar process, hard and soft palate is actual clinical problem of modern dentistry. Typical orthodontic pathology in such patients is the development of the upper jaw with a significant narrowing of the upper dentition (due to cicatricial changes) and, as a result, the formation of a prognosis, often deep, bite. Possibilities for orthodontic treatment of such patients are significantly limited due to postoperative cicatricial changes, skeletal malformation of the upper jaw, partial upper teeth adentia, small alveolar bone volume, low dentoalveolar compensation capacity, high tendency to relapse, therefore, the completion of orthodontic treatment often requires a double denture. We propose to use milled caps and present a clinical case of their application. The stages of manufacturing milled cap are the following: making prints and the manufacture of models; superposition of the facial arch to determine the position of the upper jaw; determination of the central position of the lower jaw (by facial features, with functional tests and subsequent check of the state of the chewing muscles by EMG and the position of the joints with the help of CCPT), plastering the models in the articulator, 3D scanning and digitizing models and digital modeling of the cap with ZIRKONZAHN Scan. To make the cap, Multistratum flexible was used, which is a biocompatible elastic composite material with a low plaque build-up and high aesthetic characteristics, designed for the manufacture of cynoanatomical structures. Caps are recommended to be used day and night, even during meals. Caps are removed only for daily hygiene procedures. Thus, the milled cap allows solving practical problems in non-stunted patients with non-incision of the upper lip, alveolar process, hard and soft palate such as: to provide multiple occlusions without contacts and protected occlusion with stable position of the lower jaw; restore the full function of chewing; ensure maximum retention while maintaining the width of the upper dentition; significantly improve the aesthetics of the smile (the appearance of "white aesthetics") and the face (raising the height of the bite, improving the profile, the step of the lips, reducing the second chin, rotation of the lower jaw clockwise); create optimal conditions for further permanent prosthetics, since digital models can be used as reference points for future permanent non-removable structures. So, removable milled caps are the modern optimal method of temporary long-term prosthetics, which greatly improve the functional and aesthetic status of the patient.

Aim. To assess the size of the alveolar ridge / part of the jaws in patients with gnathic mesial occlusion of the dentition.Materials and methods. A study was carried out, during which we determined the structural features of the alveolar ridge of the upper and lower jaws of 50 adult patients (from 18 to 44 years old), and also studied the presence / absence of the relationship of this parameter with the inclination of the teeth.Results. The smallest thickness of the alveolar bone in the upper jaw was observed in the area of the mesio-buccal root of the first molars and in the area of the first premolars and canines. The smallest thickness of the alveolar bone in the lower jaw was observed in the area of the vestibular surface of the first and second premolars, canines and incisors. The greatest thickness of the alveolar bone is observed in the distal-buccal region of the second molars.Conclusions. A natural mechanism promotes dentoalveolar compensation, while maintaining the amount of bone in the region of the vestibular and lingual alveolar bones to maintain the integrity of the periodontium.

The objective of the study is to evaluate the condition of the alveolar part of the upper jaw and the part of the mandible according to X-ray studies in postmenopausal women before and after surgical treatment of the atrophy of jaw bone tissue using osteoplastic material and an ossein-hydroxyapatite compound. Materials and methods: There were observed 24 women in the postmenopausal period, aged from 51 to 58 years, with atrophy of the alveolar process of the upper jaw and the part of the lower jaw who were surgically treated. Results of the study. On the basis of the obtained results of the X-ray examination, we can assume that the developed by us technique of surgical treatment of atrophy of the alveolar process of the upper jaw and the part of the lower jaw by the use of bone material of animal origin in combination with the ossein-hydroxyapatite compound allows us to intensify bone tissue regeneration processes, which further will contribute to the increase of the volume of bone tissue. Conclusions. The use of modern X-ray methods, in particular orthopantomography and cone-beam computerized tomography in the diagnosis and surgical treatment of atrophy of the alveolar process of the upper jaw and the part of the lower jaw, are highly informative, and also provide the possibility of work with a roentgenographic image in a digital format that allows a more detailed assessment of the area of surgical intervention before and after the treatment.

Introduction. Atrophy of the alveolar process of the upper jaw and part of the lower jaw is often observed after the tooth extraction. It is known that the atrophy of bone tissue is most likely observed in the first 12 months after the tooth extraction. According to the Koln classification, atrophy of the bone tissue of the jaws can be vertical, horizontal and combined. The aim of surgical treatment of jaw bone tissue atrophy is to increase the size in the area of alveolar process of the upper jaw and part of the lower jaw to further restoration of masticatory function, in particular with the use of dental implants. The aim of the study: to study the dynamics of wound healing in postmenopausal women with osteopenia after surgical treatment of jaw bone tissue atrophy using osteoplastic material and ossein-hydroxyapatite compound. Materials and methods of the study. There were observed 63 postmenopausal women with osteopenia, aged from 50 to 59 years, with atrophy of the maxillary and mandibular alveolar process, who were performed surgical treatment. During surgery, patients were divided into 3 groups: Group I – 23 patients with atrophy of the alveolar process of the upper jaw and part of the lower jaw with osteopenia, with the reduced bone tissue density, who were treated surgically for bone tissue atrophy using the method worked out by us. Group II – 23 patients with atrophy of the alveolar process of the upper jaw and part of the lower jaw with osteopenia, with the reduced bone density who were performed surgical treatment of atrophy of the jaw bone tissue using osteoplastic material of animal origin. Group III – 23 patients with atrophy of the alveolar process of the upper jaw and part of the lower jaw with the indices of bone tissue density within normal limits, who were performed surgical treatment of atrophy of the jaw bone tissue using osteoplastic material of animal origin. The results of the study. A total of 69 edentulous areas on the upper and lower jaws were examined after surgery for the treatment of jaw bone tissue atrophy. Examination of the postoperative wound was performed during the 3rd, 9th, and 14th day in the absence of complaints from patients during this period, as well as in the presence of signs of complications. Discussion of the results. According to the offered by us method of decortication of the bone tissue of the jaws, which was used to treat patients of group I, the blood supply to the postoperative area and infiltration of bone material with blood due to provoked by decortication of bone tissue bleeding, are improved. Impregnation of bone material with blood promotes angiogenesis in the postoperative area, increasing cellular activity during wound healing. It is known that due to the absence of sufficient blood supply, tissue necrosis occurs [8,9]. In patients of groups II and III the complete healing of the postoperative wound with primary tension took longer than in patients of group I. Also, in 3 patients of group II and in 1 patient of group III the wound dehiscence in the postoperative area was observed. Conclusions. As a result of the performed observations of wound healing after surgical treatment of jaw bone tissue atrophy in patients of groups I, II and III, the least complications were observed in patients of group I in the early postoperative period.

Relevance of the research topic. The frequency of the spread of the crowded position of the teeth in the frontal parts of the jaws among other dental anomalies, according to R. Ferro (2016) is 48% of the number of all examined by him. Due to the wide prevalence of anomalies in the optimization of orthodontic treatment of patients with a crowded position of the teeth continue to attract researchers. Studies of a number of authors have shown, the prevalence of malocclusion is an average of 33.7 per cent. The frequency of anomalies of occlusion, combined with the close position of the teeth in the anterior region is increased to 59-73%. The role of the third molars in the formation of the crowded position of the teeth continues to be clarifed. The goal is to increase the effciency of orthodontic treatment of patients with kuchennym the position of the teeth in the frontal parts of the jaws due to ulzibat and vibropneumotables.Materials and methods. In the study, analysis of histological preparations 35 patients aged 16-25 with kuchennym position of the cutters who underwent orthodontic treatment by the conventional method with the use of permanent equipment. Three groups were identifed: 1st-control, 2nd-before applying non – removable equipment performed fbrotomy and 3rd-after removal of non – removable equipment performed fbrotomy according to the standard procedure in the Department of maxillofacial surgery and dentistry Sammu. Results. In the examined three groups of patients, the revealed structural changes in the gingival mucosa indicate its damage and the presence of chronic productive inﬂammation as a response to physiological response to hardware orthodontic treatment. The results of comparison of microphotographs of multilayer ﬂat epithelium of the mucous membrane of the alveolar process of the jaws in three groups of patients were the answer to the task of the study.Summary. The histological structure of the attached mucous-periosteal cover of the alveolar process of the upper and lower jaw in the area of the crowded position of the teeth before orthodontic treatment was studied for the frst time with the help of morphological methods of research this allowed to reveal distinctive morphological features in this group of patients. In the comparative aspect, the morphological structure of the mucous-periosteal cover of the alveolar process of the upper and lower jaw after orthodontic treatment and in the retention period in the main and control groups of patients was studied, which deepened the knowledge of the processes of ligamentous apparatus restructuring depending on the method of treatment.

The article presents an analysis of the results of the orthodontic stage of medical rehabilitation of patients with the consequences of congenital unilateral clefts in the upper lip and palate. The material for the study was the results of hardware orthodontic treatment of 74 patients (26 boys and 48 girls) with a diagnosis of congenital unilateral cleft of the upper lip and palate. We analyzed 294 diagnostic models, 224 orthopantomograms of patients of two groups. The first group included 51 patients who underwent instrument lengthening and (or) expansion of the dentition of the upper jaw according to a traditional technique. Patients of the second group (23 patients) were treated with new methods proposed by us. It was established that the developed methods of lengthening and expanding the dentition of the upper jaw significantly increase the effectiveness of orthodontic treatment of patients, which was manifested in a reduction in the duration of active hardware treatment and a decrease in the number of complications.

The aim of the research was to study the dynamics of the microbiota’s features of oral mucosal membrane during orthopedic rehabilitation of patients with removable dentures which has an obturating part with two-layer bases. Materials and methods: To achieve this goal, our bacteriological examination of oral cavity mucosa was performed for 25 patients with partial adentia of the upper jaw and defect of hard palate and alveolar process. Results and conclusions: Of the conducted studies indicate significant shifts in the qualitative and quantitative composition of microbiocenosis in the oral cavity in patients with partial adenia of the upper jaw and a defect of hard palate and alveolar process due to representatives of moraksel, enterobacteria (representatives of the kinds Klebsiella and E. coli). The сomparing of frequency of extraction and the density of microbial colonization showed us the persistence in biotope of representatives near 13 kinds of bacteria and yeast-like fungi of the kind Candida in averages from lg (2,5 ± 0,19) to lg (5,4 ± 0,17) CFU/g. For patients who have been made a two-layered basis, materials of which are based on carboxymethylcellulose and polyvinialacetate in the period of adaptation to removable dentures, showed us that the detection of 5 component associations at 30 days was reduced by 2 times (χ2 = 5,991; ν = 2; p <0,05) . The frequency of removal and density of microbial colonization of the experimental group did not differ statistically. Among patients in the control group, the microbial colonization density increased for Enterococcus spp, for Klebsiella spp and for Candida spp. Yeast-like fungi. A significant decrease in the microbial density of the resident microflora was 1.4 times for Neisseria spp, 1.6 times for Lactobacillus spp (p <0,05).

AbstractGnathostome jaw patterning involves focal instructive signals from the embryonic surface cephalic ectoderm (SCE) to a fungible population of cranial neural crest. The spatial refinement of these signals, particularly for those patterning the upper jaws, is not fully understood. We demonstrate that Foxg1, broadly expressed in the SCE overlying the upper jaw primordia, is required for both neurocranial and viscerocranial development, including the sensory capsules, neurocranial base, middle ear, and upper jaws. Foxg1 controls upper jaw molecular identity and morphologic development by actively inhibiting the inappropriate acquisition of lower jaw molecular identity within the upper jaw primordia, and is necessary for the appropriate elaboration of the λ-junction, choanae, palate, vibrissae, rhinarium, upper lip and auxiliary eye. It regulates intra-epithelial cellular organization, gene expression, and the topography of apoptosis within the SCE. Foxg1 integrates forebrain and skull development and genetically interacts with Dlx5 to establish a single, rostral cranial midline.

In the presence of dentition defects there is a complex of morphological, aesthetic and functional changes that significantly complicate the process of diagnosis and treatment of this pathology. Dentition defects, combined with various dental anomalies and deformations very often impede rational prosthetics and at times make it impossible at all. The aim is to increase the effectiveness of orthodontic treatment of secondary deformations in patients with dentition defects by using primary dental implants as an additional skeletal support. For clinical evaluation of the effectiveness of treatment of secondary deformations in 20 patients with partial dentition defects there was performed orthodontic treatment using a straight arc technique with metal braces of the Roth system and primary detailed one-component implants as an additional skeletal support. On the diagnostic models of the jaws, the meso-distal dimensions of the lost teeth and their possible position in the dentition were determined, the shape of the dentition by methods of Pon and Korkhaus, the position of the teeth in the area of dentition defects was analyzed and the jigs of occlusion according to Andrews were defined. The use of primary dental implants as an additional skeletal support in the area of dentition defects makes it possible to control the rotation of the teeth and at the same time to use orthodontic forces of different intensity during their distal or mesial movement. As a result of orthodontic treatment of secondary deformations, we managed to achieve positive changes in the normalization of angles of dental inclination that limit the defect in patients with dentition defects. Along with the normalization of the angles of dental inclination (torque and angulation) which limit dentition defects we have noticed an increase in the distance between these teeth, which allows to restore dentition defect with dentures, better corresponding to the size of the lost teeth. Important, in our opinion, is the possibility, when using a primary dental implant as an additional skeletal support, to use the technique of segmental braces. The use of primary dental implants in the area of the dentition defect as an additional skeletal support makes it possible to restore angulation and torque of the teeth, which limit the defect, using orthodontic forces of different intensity. As a result of orthodontic treatment of secondary deformations, the distance between teeth limiting dentition defects on the upper jaw increased on average by 2.39 mm (p<0.001) and on the lower jaw – by 2.57 mm (p<0.001).

The most frequent of malignant tumor cites of the oral mucosa are tongue - 55 %, mucosa of the cheek - 12 %, the fundus of the oral cavity - 10 %, the alveolar process of the upper jaw and the hard palate - 9 %, the alveolar process of the lower jaw - 6 %, the soft palate - 2 %. Malignant tumor cells carry PD-L1 ligands on their surface and its expression level is often correlated with an unfavorable prognosis in particular for such tumors as melanoma, kidney cancer and non-small cell lung cancer. It is relevant to evaluate the correlation between overexpression of PD-L1 and overall survival in patients with malignant tumors of the oral mucosa.

The paper aims to describe the articulatory traits of the Baraba-Tatar phoneme o /ʊ̇/ by the somatic methods. The method used is magnetic resonance imaging (MRI). Eighteen Barabian tomograms comprising o-type articulation have been described and analyzed according to the technique adopted in the V. M. Nadelyayev’s Laboratory of Experimental-Phonetic Researches (Institute of Philology SB RAS). The text provides only general observations and conclusions, with a full description of all tomograms given in three tables. The experimentalphonetic analysis of the Baraba-Tatar tomograms of the vowel o allowed the author to draw several conclusions. There is a variability of the o-type tunings in Barabian, the most typical being the central-back narrow labialized ejective realization. Though it is very narrow and is phonetically transcribed as /ʊ̇/, it is acoustically perceived as o. While producing the sound o, the oral and pharyngeal cavities become very small, producing the effect of tension. Additional narrowing occurs between the soft palate and the tongue back as well as between the upper teeth and the lower lip, thus preventing the airflow from free release. The lip position is also unusual: instead of protruding forward, the upper lip moves back, tightly covering the upper teeth to produce an interesting acoustic effect. To sum up, further investigation of all vocal system units of Baraba-Tatar is needed to draw ultimate conclusions about the typological belonging of the language under consideration.
