Kuts P. Prediction and prevention of complications in dental implantation (clinical and experimental study).

Thesis is dedicated to increasing the effectiveness of dental implantation due to prediction and prevention of complications their early diagnosis during planning and carrying out of clinical implantation followed by dental protheses fabrication. The study involved 400 patients aged 21 to 71 years who have applied to the Department of Prosthodontics of NMU Clinic with a desire to get dental implants supported dental protheses. In these patients were installed 1247 intraosseous implants and various orthopedic constructions were fabricated during the period from 2001 to 2011 inclusive. In this paper was made an attempt to compare the adverse outcome of dental implantation (DI rejection) with the state of bone tissue at the implant site, the state of the soft tissues, construction and superstructure material, with immunological status of the patient, with the state of the system of blood neutrophils, with genetic predisposition to implants rejection as these factors may affect the structural and metabolic processes in bone and as a result, engraftment in DI. Research of techniques to prevent complications of dental implantation in the stages of diagnosis showed the presence of such possibility in use, except for clinical and laboratory methods complex of immunological, cytological, molecular-genetic methods, the results of which form the basis for risk prediction in implant treatment. The research results and built on their basis mathematical model with predictive potential of 92,4 % with a high probability can predict the outcome of dental implantation and to avoid unintended consequences. Based on the results algorithm was developed to prevent possible complications of dental implantation, established criteria for the possibility of expanding the indications for dental implantation in patients with somatic diseases using preventive and prophylactic drug therapy. It was proposed to use the guide 3D-templates based on data obtained by cone-beam tomography and computer planning, which significantly reduces the risk of errors on the surgical stage, reduces the burden on the patient during surgery and makes it possible to establish a temporary superstructure in a shorter time and thus provides a predictable positive result. Justified the use of individual zirconia abutments on titanium platforms using CAD / CAM technology and all-ceramic crowns to get high aesthetic and functional outcome in implant supported prosthetics.
