Different assumptions concerning jawbone model, loading condition in previous and present studies.
| | Jawbone models | Angulation of abutments | Loading condition |
| Clelland et al. [11] | Models constructed from computed tomography images | 0°, 15°, and 20° | 178 N applied along the long axis of abutment | Saab et al. [9] | Models constructed from computed tomography images | 20° | 178 N oblique loading | Kao et al. [12] | Simplified models | 0°, 15°, and 25° | 89 N oblique loading | Tian et al. [13] | Simplified models | 0° and 20° | 100 N axial and oblique loading | Bahuguna et al. [19] | Simplified models | 0°, 10°, 15°, and 20° | 100 N, 125 N, 150 N, 175 N, and 200 N axial loading; 50 N oblique loading. | Present study | Simplified patient-specific models and simplified models | From 0° to 60° | 100 N axial and oblique loading |
