JUSTIFICATION OF A CHOICE OF THE FIXING MATERIAL OF THE IMMOBILIZING SPLINTS MILLED BY CAD/CAM METHOD
The effectiveness of new CAD/CAM milled splints to immobilize the mobile teeth with diseases of periodontal tissues by the various experimental methods are investigated. The durability of the fixation immobilizing splints from titanium alloy, zirconium oxide and polymer to the surface of natural teeth by cyclic fatigue and static tensile tests are studied. Different composite or glass ionomer fixing materials (cements) are used. It is shown that the best adhesion is achieved in the case of next materials for immobilizing splints: zirconium dioxide and titanium alloy and fixing glass ionomer cements. It is established that the polishing of splits samples by special polishers “NTI” (Germany) reduces the roughness of the samples selectively with respect to construction materials.
