Background
The dental implantation system is a device for implanting the dental implant into the upper and lower jawbones of a human body tooth-missing part in a surgical operation mode, and repairing the dental prosthesis is arranged at the upper part of the dental implant after the surgical wound is healed. The dental implant system comprises an implant, a base and a central screw, wherein the implant is implanted into an alveolar bone of an oral cavity, the central screw locks the base on the implant, and then a prosthetic tooth is installed on the base.
Normally, the gap between the inner cavity of the implant and the outer wall of the base is smaller, and bacteria and foreign matters in the oral cavity are difficult to pass through the gap. In the conventional gap test method of the dental implant system, the assembled dental implant system is generally cut, the gap between the inner cavity of the implant and the outer wall of the abutment is measured, and the connection tightness of the dental implant system is judged according to the size of the gap. However, the dental implant system bears continuous cyclic biting force in the use process, and under the action of the continuous cyclic biting force, a larger gap can appear on the joint surface of the inner cavity of the implant and the outer wall of the abutment, bacteria and foreign matters in the oral cavity easily enter the dental implant system from the gap, and infection is caused in the dental implant system.

The volume of the dye solution is N, and the mass concentration of the dye solution is aIn step four, the mass concentration of the dye solution in the water in the accommodating space 210 is measured as b by using a spectrophotometer, and as the surface of the dental implant system 300 is cleaned and dried, the dye solution in the water is derived from the dye solution leaked from the dental implant system 300, the total volume of the dye solution in the water and the water at the moment is set as X, the mass of the dye solution in the water is X x.b, the volume of the water added into the accommodating space 210 is set as V, and the volume of the dye solution leaked from the dental implant system 300 is set as Z 1 The mass of the leaked dye solution of the dental implant system 300 is Z 1 * a, it follows that: x=v+z 1 And Z is 1 * a=x×b, yielding Z 1 =v×b/(a-b), x=v×a/(a-b); in step six, the mass concentration of the dye solution in the water in the accommodating space 210 is measured by a spectrophotometer to be c, and if the total volume of the dye solution in the water and the water at this time is set to be Y, the mass of the dye solution in the water is set to be y×c, and the volume of the dye solution leaked from the dental implant system 300 is set to be Z 2 The mass of the leaked dye solution of the dental implant system 300 is Z 2 * a, since in step four the volume of water measured is taken out of the accommodation space 210 is V 1 The mass of the dye solution contained in the water is V 1 * b, it follows that: y=x+z 2 -V 1 And y=x×b+z 2 *a-V 1 * b, obtaining Z 2 ＝(b-c)*[V*a/(a-b)-V 1 ]/(c-a)，Y＝(b-a)*[V*a/(a-b)-V 1 ]/(c-a); so that the volume Z of dye solution leaking from the dental implant system 300 can be derived 2 The method comprises the steps of carrying out a first treatment on the surface of the Since the connection tightness of the dental implant system 300 can be ensured after the normal assembly, the dental implant system 300 is not easy to leak before the fatigue test is performed, and in theory, the mass concentration b of the dye solution measured in the fourth step is 0, then Z is zero 2 ＝(V-V 1 )*c/(a-c)，Y＝(V-V 1 )*a/(a-c)。
Dye solution volume Z leaked from anterior dental implant System 300 for fatigue testing 1 Volume Z of dye solution leaked from dental implant system 300 after fatigue testing 2 For Z 1 And Z is 2 For comparison, if Z 2 Greater than Z 1 It was confirmed that a large gap occurred between the implant 310 and the abutment 320 after the fatigue test, so that the dental implant was plantedThe dye solution in the containment chamber 340 of the system 300 leaks. Fatigue tests are carried out on different types of dental implant systems 300 through the dental implant system micro-leakage test method, and the volume Z of the dye solution leaked by the different types of dental implant systems 300 is obtained 1 And Z is 2 So that the connection tightness difference of the various dental implant systems 300 under the fatigue test can be discriminated.
While the preferred embodiments of the present invention have been illustrated and described, the present invention is not limited to the embodiments, and various equivalent modifications and substitutions can be made by one skilled in the art without departing from the spirit of the present invention, and these are intended to be included in the scope of the present invention as defined in the appended claims.
