Monocortical fixation of mandibular angle fractures and osteotomies were conventionally done by 90° screw plates. Recent developments in screw plate designs enable multiple angle applications. Objectives: To compare and determine the force resistance and fixation stability of multiple angle applications of the Minimal-Invasive-Monocortical-Angle system (MIMAS) Methods: Angular fractures were simulated on polyurethane artificial mandibles with a surgical saw. The mandibles were fixated with a MIMAS system with screw angles at 75°, 60° and 45° respectively and compared with mandibles fixated with a 90° conventional screw plate (n=15). Mandibles were mounted in a specially designed holding device to enable testing in a Zwick testing machine and the anterior part of the mandible were compressed with a rounded lever placed on the occlusal surface of the first molar to an arbitrary point of failure (3mm) and maximum extension of 5mm. The force resistance (N) was recorded at 0.1mm travel intervals. When considering force resistance curves of the individual screw angle plates, the slope of the curve give an indication of the relative fixation of the fracture, with higher slope values indicating better fixation. Results: Comparison of the force resistance at 3mm displacement indicated that there was no significant difference (p>0.05) between the values for 90° (17.62N) and 75° (14.99N), but force resistance for 60° (19.14N) and 45° (18.20N) was significant better (p<0.05) than for 90° and 75° angled screw plates. Slope values were 0.4304 (90°), 0.4472 (75°) 0.4026 (60°) and 0.4229 (45°). Slope differences were not statistically significant different for any sample group (p>0.05). Conclusion: The MIMAS system with screw angles at 60° and 45° showed higher force resistance values when compared with 90° and 75° screw angles. Slope values indicated no difference in fixation stability of the different screw angle plates.
