Abstract：Objective To evaluate that the retentive force of the micro-titanium nails can satiate the clinical appliance requirements of the full overdenture. Methods Two piece of the micro-titanium nails with 2 mm in diameter and 5mm in length were parallel screwed into modified and freshly isolated pig mandibles. The fixed micro-titanium plates were placed into the trench. The trench was fixed on a base of electronic universal testing machine. The specimens were load-ed in tensile at crosshead rate of 1mm/min with a 1000N in frame. Results The maximum tensile strength among the groups is 564.25N, the minimum is 441.08 N,and the average is(513.15±44.92)N. Conclusion The maximum tensile strength of the micro-titanium plate and micro-titanium nail system is much higher than the attraction of magnetic at-tachment and the maximum occlusal force which is met when patients are chewing food with complete denture,it could satiate the clinical appliance requirements of the full overdenture.
