摘要:
The invention relates to the sector of medical prostheses, namely to devices for prosthetics on implants. It minimizes graft rejection by providing a natural distribution of masticatory pressure from the implant on the bone part (alveolus), which is achieved except rigid attachment between the intraosseous and the coronal portion of the implant by the use of cushioning member made of a fluoroplastic material mounted between intraosseous and crown portions having similar to natural tooth property of the ability to move vertically when acted upon by a distance d about 20 microns. Dental implant with a shock absorber, comprising a coronal portion, the intraosseous portion made of a bioinert porous material with an external thread (the form of the screw) for fixing to the jaw bone, having a vertical axis of the blind hole of two diameters, the upper part of the cavity of the hexagon for screwing intraosseous portion of the implant in the jaw bone bed, in the lower internally threaded for screw coupling and cushioning pad (abutment) is made of a fluoroplastic with a through hole on the vertical axis two diameters, creating at the transition support surface for the connecting screw, and includes (conditionally divided) into three parts coronally into a cylindrical shape, cervical form of an inverted cone with a support platform for crowns and vnutriimplantatnoy shaped hexagon size compatible with the internal hex cavity intraosseous part of the implant and the cavity in the abutment of the screw cap containing PTFE liner.Полезная модель относится к отрасли медицинских протезов, а именно к устройствам для протезирования зубов на имплантатах. Обеспечивает минимизацию отторжения имплантата за счет обеспечения естественного распределения жевательного давления от имплантата на костную часть (альвеолу), которое достигается исключением жесткого крепления между внутрикостной и коронковой частью имплантата за счет использования амортизирующего элемента, выполненного из фторопласто
