FIELD: medicine; medical engineering.
SUBSTANCE: method involves applying mucoperiosteal trapezoid flap separation procedure, opening external maxillary alveolar process plate, building screw implant bone bed for perforating maxillary sinus, separating mucous membrane of sinus fundus from underlying bone substrate, filling the arisen cavity with collapan granules or its liquid solution, setting two-stage screw implant into the prepared bone bed with periosteal wound and mucous membrane being tightly sutured. Maxillary sinus fundus perforation is carried out with device mounted on prepared bone bed and having bone trephine with tail and manual wing nut at the end. The trephine is introduced into through axial hole in bone-support screw which external surface is identical with screw surface of screw to be installed. Procedure for separating mucous membrane of sinus fundus from underlying bone substrate is carried out using device that is mounted on prepared bone bed having threaded rod with smooth ball on one end and manual wing nut at the other one. The rod is introduced into through axial hole in bone-support screw which external surface is identical with screw surface of implant to be set. Procedure for filling the whole arisen cavity volume with collapan granules uses the same device that is applied for separating mucous membrane of sinus fundus from underlying bone substrate. The cavity is filled with liquid solution by means of the device mounted on the prepared bone bed. The device has bone-support screw which external surface is identical with screw surface of implant having axial cylindrical through hole becoming conic at the end where syringe filled with liquid collapan powder and patient blood is set.
EFFECT: reduced risk of traumatic complications; high reliability of the method.
