Periodontal disease in the adult population is one of the most pressing problems of dentistry around the world. Thanks to the introduction of modern technologies in practice, it was possible to identify the main mechanisms of the development of this disease at the molecular and genetic level. The interaction of periodontal pathogens with immune factors of antimicrobial protection of the body is the basis of periodontal tissue inflammation and further leads to the destruction of the alveolar bone. Epithelial cells of the gum mucosa play a crucial role against periodontal pathogenic bacteria. Factors of innate immunity play a role not only in antimicrobial protection, but they also support the conditions necessary for the healing and regeneration of periodontal tissues. Therefore, various therapeutic approaches that affect the factors of innate immunity are considered as effective and promising. Clinical examination and determination of factors of innate immunity were performed in 115 patients. Healthy individuals made up a group of 30 people. Patients with chronic generalized periodontitis with varying degrees of severity were 85 people. Each patient underwent orthopantomography on the orthopantomograph Orthophosis XG DS/Ceph (SIRONA Dental System GmbH, Germany) in order to assess the state of the bone tissue of the jaws (the degree of destruction of the cortical layer, the degree of resorption of the interalveolar partitions). Targeted intraoral radiographs were used to assess the state of bone tissue and the quality of surgical treatment. Immunological methods of research were carried out in several stages. The findings of this article make the claim that the use of autologous complex immunopeptides in the surgical treatment of periodontitis reduces the time of achieving a therapeutic effect 2 times, resulting in the rapid relief of the symptoms of inflammation and acceleration of reparative processes.

The aim of the study. Carry out a comparative analysis of the support ability of human jaw bone tissue in monocortical and bicortical installation of a mini-implant of own design OMG. Research methods. In order to study biomechanical characteristics of developed OMG mini-implant and bone tissue capacity during monocortical and bicortical installation, the finite element method (MSE) was used. The scheme and finite element 2-D model of bicortical installation of OMG mini-implant (length 8 mm, diameter 1.8 mm) provided full penetration through one layer of cortical bone equal to 1 mm, the entire cancellous bone and immersion in the second layer of cortical bone by 0, 5 mm. No implantation was immersed in the second cortical layer of bone during monocortical installation. A single force load of 1 N was applied in the horizontal direction parallel to the cortical plate of the bone. Results of the study. One of the most important factors leading to the success of the use of a mini-implant is its stability in the process of orthodontic treatment. Quite a high level of failure in the monocortical installation of mini-screws has led to the search for better methods to ensure the stability of their use. This was a bicortical method of fixation, based on the placement of the minig screw in the thickness of the two cortical plates of the jaws. Area for such installation of mini-screws can be a site of a palate and alveolar sprouts at installation of miniimplants through all its thickness. As shown by our data on the use of the finite element method under the force load of the biomechanical system "bone - mini-implant", the stress concentration zone is located in the area of the cortical bone of the jaw. The results of the calculation of the maximum stresses (σmax, MPa) and the maximum possible displacements (umax, mm) of the mini-implant in the biomechanical system "bone - mini-implant" in monocortical installation were, respectively, 8.27 MPa and 0.300 * 10-8 mm and in bicortical installation 6.00 MPa and 0.201 * 10-8 mm. The bicortical method of fixing the mini-implant in the jaw bones significantly increases the ability to resist deformation of this type of biomechanical system under force loads of the mini-implant. In the bicortical method of mini-implant placement, the extreme values of equivalent according to Mises stresses in the upper part of the cortical bone of the jaw are reduced by 27%. This can be explained by a significant increase in the area of contact due to the two layers of the cortical bone of the jaw with the surface of the mini-implant. Conclusion. The bicortical method of installing mini-implants is a more effective and reliable way to provide skeletal support during orthodontic treatment.

Facial asymmetry, following early childhood condylar trauma, is a common complaint among patients who seek surgical treatment. G.D.M., a 27-year-old male patient, sought professional help to correct his cosmetic flaw, caused by a condylar fracture when he was 8-years-old. After the proper orthodontic treatment, he underwent a double jaw orthognathic surgery and, 9 months later, a second one to correct the remaining asymmetry. Two years after this second procedure, the patient is still under surveillance and has no complaints.

Background. Hereditary gingival fibromatosis is a fibrotic enlargement of the gingiva. It may exist as an isolated abnormality or as part of multisystem syndrome. This paper reports a case of 16-year-old male with generalized severe gingival overgrowth, involving the maxillary and mandibular arches and covering almost all teeth.Methods. Periodontal management of gingival enlargement included gingivectomy in both arches except in the lower right molar region where flap surgery was done under general anesthesia. After a 2-month followup period, orthodontic treatment was started with fixed appliances. Monthly periodontal checkups and maintainance (scaling and polishing) were scheduled to control the gingival inflammation.Results. Reevaluation of the patient of surgical treatment after two months did not show any recurrence of condition; however, minimal overgrowth was noted 1 month after the beginning of orthodontic treatment which was treated nonsurgically.Conclusions. Although the risk of recurrence is high with this condition, surgical treatment with correction of malocclusion and regular followup can provide excellent outcome as seen in this case.

Periodontal Biotype

A feature of periodontal anatomy, in which the proximity of the roots of the teeth to the cortical plates or the sections of the roots of the teeth is determined and that are not included in the bone tissue, contributes to the onset of gum recession or its progression during or after orthodontic treatment. When teeth move towards the cortical plate, it can be destroyed. At the same time, teeth moving towards the center of alveolar ridge often causes the formation of bone tissue from the vestibular side that contributes to the improvement of fixing ability of the periodontium. In case when oral vestibular size of the roots of the teeth exceeds the volume of periodontal tissues, orthodontists use treatment methods that contribute to creating space within the dentition without changing its size: grinding of approximate surfaces and selective extraction of teeth. Knowing and considering periodontal biotypes, clinicians can predict the course of treatment, apply appropriate methods of orthodontic benefits to minimize alveolar resorption and ensure favorable results.

Partial Glossectomy

Introdução: a macroglossia é uma condição incomum e pode ser caracterizada como uma desordem por hipertrofia muscular, podendo ter também origem tumoral, endócrina, causas congênitas e doenças adquiridas. Inúmeras são as técnicas cirúrgicas para correção desta anomalia, porém, o plano de tratamento deve ter como base a etiologia da macroglossia. A correção cirúrgica objetiva a retomada de forma e função da língua, reestabelecendo a capacidade mastigatória, respiratória, fonética e estabilidade oclusal. Objetivo: relatar a comunidade científica um caso de glossectomia parcial para correção de um quadro de macroglossia, facilitando assim, a estabilidade do tratamento ortodôntico do paciente. Relato de caso: Paciente de 50 anos, leucoderma, em tratamento por ortodontia corretiva há mais de 18 meses, sem sucesso observado. Devido ao quadro de instablidade ortodôntica, maloclusão sem resolução passiva, macroglossia diagnosticada e redução da capacidade respiratória foi optado por realizar a glossectomia parcial. O procedimento foi realizado sob anestesia geral, onde removemos o tecido muscular a partir da abordagem de buraco de fechadura (Técnica de Kole). Conclusão: constatamos no presente caso, que a técnica de buraco de fechadura empregada neste paciente se mostrou eficaz, uma vez que obtivemos uma melhora estética e funcional, diminuindo o comprimento e largura da língua. Da mesma maneira, o tratamento ortodôntico foi passível de ser finalizado.Descritores: Macroglossia; Cirurgia Bucal; Glossectomia.ReferênciasTopouzelis N, Iliopoulos C, Kolokitha OE. Macroglossia.
