Detection method for special sample preparation fit clearance
Abstract
The invention discloses a special sample preparation fit clearance detection method, and belongs to the technical field of medical instruments. The method comprises the following steps: step 1, establishing a three-dimensional assembly model of an implant, an abutment and a central bolt through three-dimensional software; 2, a tool placing model is established through three-dimensional software; 3, an assembling model groove is formed in the top face where the tool model is placed; 4, a tool placing model is manufactured in a 3D printing mode; 6, cutting the assembly body along a cutting line parallel to the central axis of the assembly body; seventhly, part of the cut assembly is placed in an assembly model groove of the grinding and polishing tool; 8, manually grinding and polishing along the upper surface of the grinding and polishing tool; and 9, measuring fit clearances of the implant, the abutment and the central bolt on the upper surface of the special sample by using an optical measuring instrument. The detection precision of the fit clearance is improved, the sample preparation efficiency and accuracy are improved without depending on manual observation, and the manpower and material resource cost is saved.
