Syennikov O. Clinical and mathematical substantiation of designing of subperiosteal implants.

The work is devoted by a question increase of efficiency treatment of the patients with different defects of tooth lines at the expense of development of rational designs subperiosteal implant (SI). For achievement of the purpose the mathematical modeling of interaction SI with subject bone by a fabric which submitted as of a contact task - beam with elastic monoslice by the basis and system integro-dinerential of the equations was carried out which have permitted to receive the analytical formula of the decision of a problem. During research of the accepted model the certain size bon's rebuff of a fabric k=200 кН/см З, which has permitted to conclude, that by a basic element of transfer of chewing loading on bone the fabric is transfer a tape SI. The numerical experiment permits precisely to look after the tendency of reduction stress-deformation of a status simultaneously in implants and bone of a fabric at increase of values of size of length L and width b transfer of a tape of implants. The made co mputer program by an algorithmic language Fortran 6,0 with use of operational system Windows-96,98,2000 permits not only to determine necessary constructional parameters in each concrete case, but also to inspect the received data. Study of a anatomical and topographical building perceiving implant's box has permitted to allocate some features of a building alveolar bone on the top jaw. In most cases they have sharp blade-went the form. On the bottom jaw anatomical the revealed following variants of a building alveolar bone: slanting, direct, brearing and combination. The original ways of realization subperiosteal are developed at different types of defects of tooth lines. The study of adaptation processes in chewing muscles after realization subperiosteal behind the data EMG-researches has permitted to establish, that the basic registered changes occur during 1 month after realization implantation and practically about 3 month, changed only insignificant changes per 6 months comes to an end. And the approach adaptation of processes occurs basically in the same terms irrespective of a type of defect of a tooth line. The rating of results has permitted realization subperiosteal implantation behind the data EMG to us to develop and to offer a rather objective way of definition of efficiency subperiosteal implantation.
