Разработка новой конструкции отечественного зубного имплантата и экспериментальное обоснование его использования

Аннотация

The urgency and relevance of the dissertation topic. For the last few decades, implant dentistry has become a very popular solution to remediate the loss of teeth and durably restore both esthetics and mastication ability to (partially or fully) edentulous patients. A primary indicator for success of dental implants is osseointegration or direct implant-bone contact. Successful osseointegration is an indication of favorable response of surrounding bone to insertion of the dental implant. The literature indicates that factors such as implant surface topography, implant surface roughness, bone-implant interface, implant design, length and diameter of the implant, site geometrical characteristics, and properties of the supporting bone are important factors on load transfer mechanism and implantbone response. Therefore, in the field of scientific research the development of new materials, structures of dental implants remains one of the most important problems in dental implantology. The aim of the research work is to develop a new design of the domestic dental implant. Scientific novelty of the research work is the following: the new design of the domestic dental implant "Implant.uz" made from titanium VT-1.00 with a unique design of the intraosseous part was developed for the purpose of optimizing the biocompatibility with the surrounding bone tissue (patent of the useful model "Dental Implant" № FAP 00819,2013); for the first time, according to the developed engineering and technical documentation, the prototype model of the domestic dental implant "Implant.uz", which corresponds to the set of ECK.D standards according to the rules for the development of official registration and using of documentation in accordance with GOST 2.001-90; it was proved in the experiment that the implant "Implant.uz" can be used to replace the defects in the dentition and the positive dynamics of osseointegration at the implant-bone interface is justified; the biomedical safety of the dental implant " Implant.uz" was established in the experiment, the tightness of this design was studied, as well as the toxic, irritating, allergic effect on the body of experimental animals.
