摘要: The purpose of this study was to compare the fracture strength and mode teeth restored with fiber/titanium post, polyethylene fiber, adhesive composite. mesial, distal, palatal walls human maxillary molar were removed, so that only buccal wall remained. Group 1, caries-free molars, used as a positive control group remaining groups follows: 2, composite; 3, fiber 4, post 5, 6, titanium 7, A universal testing machine for tests. Compressive loads applied at an angle 90 degrees on occlusal surface specimens crosshead speed 1 mm/min until occurred. Kruskal–Wallis Mann–Whitney U tests adopte...
