title: [Study of the three-dimensional structure and biointegrative characteristics of porous orbital implant materials].
abstract: Plastic repair operations in ophthalmic surgery frequently require the use of various biological and artificial implants. The biointegrative properties of implants are provided by the physicochemical characteristics of the material that is used to make them, by the three-dimensional structure of an implant and its immunological characteristics. The authors comparatively studied the three-dimensional structure of a Carbotexim-M carbonic felt, porous polyethylene, polytetrafluoroethylene, demineralized bone alloimplant, and marine coral hydroxyapatite, which are employed in orbital surgery and also examined the adhesion of fibroblasts to their surface. Comparative study using scanning electron microscopy could reveal the specific features of the relief and parameters of the threshold space of the study implant materials. A method was developed to estimate cell adhesion to the implant materials, by taking into account three-dimensional structure of their surface.
