Description
Technical field
The present invention relates to a kind of two-dimensional freedom oral cavity material grinding repairing external analog testers, belong to the oral cavity material grinding and repair in-vitro simulated device.
Background technology
In the Prosthodontics field, utilizing the high speed dental handpiece to carry out Oral Repair is a gordian technique difficult problem in the Oral Repair medical science to adjust dummy and interdental occluding relation, the difficult point of problem comprises: the complicacy of oral environment, dummy is removed difficulty, produce very easily that the grinding reparation destroys and the early stage little destruction and the sudden macroscopic failure that cause dummy, and dynamic cutting force, vibration and noise are to uncomfortable property that the patient produced.For a long time, the dental prosthetic process only can rely on dentist's experience, judge and patient's clinical sensation and the theoretical foundation of the science of shortage qualitatively.Therefore, utilize the high speed dental handpiece carry out dental material fast precisely Oral Repair be one and be rich in challenging work, the skillful of its skill not only depends on a large amount of clinical practice activities, and depends on the profound understanding of doctor to various physical phenomenons to a great extent.In order to address the above problem, people such as the S.C.Siegel of University of Maryland and J.V.von Fraunhofer A, designed an easy simulation Oral Repair topping machanism [1], utilize high speed dental handpiece and diamond abrasive tool that dental material is carried out in-vitro simulated grinding reparation, carried out a series of deep researchs [1] at this problem of material removing rate.Doctor B.Lawn of U.S. academician of the Chinese Academy of Engineering, NIST etc. utilizes the impression experimental method, and the brittle fracture and the accurate plastic failure of tooth section pottery carried out big quantity research [2].Yin Ling (L.Yin) and S.Jahanmir, the L.K.Ives of NIST cooperate with doctor X.Dong, start with from material science and tribology, develop the tooth section pottery Oral Repair experimental provision of a kind of quasistatic, permanent grinding force, and inquired into various dental ceramic alloys microstructures and diamond abrasive granularity are repaired surface quality and diamond abrasive tool wearing and tearing to grinding influence [3-6] in view of the above.Result of study shows: under the grinding force effect, tooth section ceramic grinding surface breakdown degree depends on the microstructure of material, and the diamond abrasive granularity plays a decisive role to the ceramic grinding surface breakdown.Yet above-mentioned work only is confined to the materialogy category, and experimental data obtains under static state or quasi-static environments, and also there is big gap in the clinical practice of instructing Oral Repair.Therefore, repair in the research in tooth section, its test unit is demanded urgently further perfect in design and manufacturing, need develop the testing machine of real simulated actual clinical reparation more, thereby be used for the research that the grinding of dental material oral cavity is repaired.
