Comparative research of implants with three types of surface processing (TiUnite, SLA, RBM), control, with periimplantitis and processed by 2780 nm Er;Cr;YSGG laser

Abstract

Research objective - an assessment of morphological and element composition various as surfaces of implants, with the diagnosis periimplantitis, subjected to processing by the Er laser; Cr; YSGG wave of 2780 nanometers long in comparison with not subjected. Used implants of three producers: (1 - Nobel Biocare (Sweden), TiUnite surface; 2 - XIVE Dentsplay (Germany), SLA surface; 3 - BioHorizons (USA), RBM surface). Electronic and microscopic methods investigated surfaces of the control (new) implants removed with the diagnosis periimplantit, with the diagnosis periimplantit and processed by the laser. It is revealed that the surface of new sterile implants isn't ideal, on it there are traces of impregnation by inorganic connections, a large amount of foreign chemical elements, especially on a surface of SLA of an implant of XIVE Dentsplay is revealed. The surface of skilled implants with the diagnosis periimplantit is very strongly polluted by carbon (C), phosphorus (P), sulfur (S), silicon (Si), etc., being formed on a surface during an inflammation. After processing of the same surface by the Er laser; Cr; YSGG wave of 2780 nanometers long occurs surface clarification, and the element structure almost completely corresponds to the control.
