Jinan Zhongce Electromechanical R&DYKT-CH01 Dental Material Thickness TesterTo achieve precise measurement, follow these steps:

Benchmark calibrationTightly adhere two transparent glass plates and measure the initial thickness (error ≤ 1 μ m).

Material fillingApply 0.10mL of cement evenly between glass plates and maintain a pressure of 150N for 10 minutes.

data calculationMeasure the total thickness after filling, and the difference is the film thickness.

Standard requirements:At least 4 out of 5 tests yield results ≤ 25 μ m, otherwise it is deemed unqualified. This device complies with international standards such as YY 1042-2023 and YY 0271 series, providing reliable data support for clinical use.

The wear resistance of composite resin is the key to determining the lifespan of the restoration. Jinan ZhongceYKT-MH01

Dental composite resin abrasion resistance testerAccording to YY/T 0113-2015 standard,Mainly complete the pre grinding and abrasion test of the sample. After the pre grinding is completed, the sample is cleaned and dried, and the initial weight of the sample is weighed using a precision electronic scale with an accuracy of 0.0001g. Then, the sample is installed back into the fixture for abrasion test.

Wear test：After the sample falls, under the action of wear load, the abrasive is squeezed and comes into contact with the grinding pair, and friction is achieved in a relative circular motion mode, with a friction period of 30 ° angle; After each friction cycle is completed, the sample rises by (10 ± 0.5) mm, rotates by 90 °, and completes a non-contact circular motion of 30 ° relative to the grinding pair. The circular motion radius of the sample is 27.5mm; during friction, the linear velocity at the center of the sample is 75mm/s.

During the wear process, whenever the sample falls, the abrasive can be collected and laid between the sample and the grinding pair, with a thickness of not less than 5mm

data quantification：Calculate the difference before and after wear using the weighing method, and obtain the result.

As one of the key dental instruments, the stability and accuracy of the performance of the car needle directly affect the treatment effect and patient comfort. In order to ensure stable cutting performance and precise cutting path of the needle during high-speed rotation,Jinan Zhongce ElectromechanicalYKCZ-TD01 Dental Needle Radial Bounce Testerbasis:

Neck fracture of the needle may lead to treatment interruption or even patient injury. Jinan Zhongce ElectromechanicalYKCZ-QD01 Dental Needle Neck Strength TesterIt is a specialized instrument designed and manufactured in accordance with the provisions of YY 0302.1-2010 "Needle for dental rotary instruments Part 1: Steel and hard alloy needles", YY 0302.2-2016 "Needle for dental rotary instruments Part 2: Trimming needles", and YY/T 0874-2013 "Test methods for dental rotary instruments" regarding neck strength testing of dental needles.

Initial measurement:Use a dial gauge to record the radial runout value of the needle tip of the car.

Dynamic force application:Apply force at an angle of 22.5 ° to the push-pull force gauge and measure the jumping value again after 5 seconds.

Result judgmentIf the deformation of the head exceeds the standard, it is judged as unqualified.

Load standard:Steel needles need to withstand a force of 23.35N, while hard alloy needles need to withstand a force of 24.05N to ensure clinical safety.

The permeability of dentinal tubules affects the protective effect of materials on dental pulp,Jinan Zhongce ElectromechanicalYKZS-B01 dentin permeability tester needleA testing instrument designed according to the pharmaceutical industry standard for in vitro evaluation of the occlusion effect of dental dentinal tubules in YY/T 1829-2022 dentistry. This device is suitable for dental materials that can block dentinal tubules. The testing steps are as follows:

Device assemblyFix the dentin fragment in the sealed chamber and withstand a pressure of 20cm water column.

flow measurementCalculate the liquid permeability and evaluate the sealing performance of the material by measuring the speed of bubble movement.

Sealing verificationBefore the experiment, use a substitute piece to check if the device is leaking air.

clinical significanceThis test can screen materials that can effectively seal dentinal tubules and reduce postoperative sensitivity.
