FEATURES OF PREOPERATIVE MANAGEMENT AND METHODS OF EXAMINATION OF PATIENTS OF GROUPS UNDER RESEARCH

Despite the active ability to repair, it is frequently noticed that the independent potentialof bone tissue is insufficient, that is a serious problem in reconstructive maxillofacialsurgery, orthopedics and traumatology. In recent years, there has been an activesearch for implant material that would match the autologous bone in its properties andcharacteristics. Tissue engineering technologies allow to create tissue equivalents tobone tissue using autogenous stromal cells deposited on biocompatible or biologicalmaterial of tissue engineering design. The article presents the features of preoperativemanagement, description of the used examination methods and bone augmentationmaterials in patients of the groups under study.Objective – to use a set of adequate methods of examination and optimal preoperativemanagement of patients of the group under study during sinus lifting, post-extractionsocket preservation, osteosynthesis for mandibular fractures and impacted wisdom teethextraction, which were accompanied by the use of bone augmentation materials based onmultipotent mesenchymal stromal cells.Material and methods. 280 people aged 18 to 55 with partial or complete adentiaand atrophy of the alveolar process of the jaws, with chronic periodontium infectionand chronic generalized periodontitis, with fractures and impacted third molars wereexamined in the Department of Surgical Dentistry and Maxillofacial Surgery of theChernivtsi Regional Clinical Hospital. All patients were planned to make orthopedicstructures based on dental implants.Results. The use of computed tomography in preoperative examination of patients in thestudied group allows not only visually to examine the object, but also to perform directdensitometric analysis with measurement of attenuation coefficients in Hounsfield units,that is a significant advantage over X-ray examination.Conclusions. The use of bone augmentation materials based on multipotent mesenchymalstromal cells of adipose tissue during dental operations improves the regenerativeproperties of bone tissue and helps to reduce the duration of inpatient treatment.
