Metal Injection Molded Scaler Parts

The field of dental medical equipment relates to an ultrasonic scaler treatment head and its application. The ultrasonic scaler treatment head includes a base and a working tip, the base is provided with a flushing water jet pipe, and the working tip is fixed on the base .On the top, the contact surface between the working tip and the base is provided with a flushing water jetting hole connected with the flushing water jetting pipe, and the working tip is made of carbon fiber or plastic material. The purpose of the present invention is to break through the existing ultrasonic scaler carbon fiber and plastics. The treatment head cannot be used at high frequency, so it provides a treatment head structure of ultrasonic scaler with reasonable design and can be used under high frequency, which greatly reduces the work intensity of medical staff and the treatment time of patients, and can effectively improve doctors' performance. Work efficiency and treatment comfort.

With the continuous development of modern technology, ultrasonic scalers have been increasingly widely used in the field of stomatology. Although the implant technology is becoming more and more mature, whether the plaque on the implant surface above the gingival can be effectively controlled is still an important factor in determining the long-term success rate of implant therapy. Because the metal treatment head will scratch the surface of the implant and cause a rough surface that is easy to attach plaque, it is generally not used for cleaning the implant. Commonly used implant cleaning tools are hand-operated plastic or carbon fiber instruments. However, due to the limitation of shape and volume, hand instruments are inefficient and often cannot completely remove plaque and calculus. Therefore, the scaling of implants has always been a difficult problem for dentists. Some foreign manufacturers of ultrasonic scalers have applied carbon fiber or plastic to the ultrasonic treatment head to obtain good treatment effects. Compared with ordinary metal treatment heads, it has the advantages of soft texture and low price. Medium- and long-term clinical studies conducted by well-known stomatology schools at home and abroad have shown that carbon fiber or plastic treatment heads not only have good cleaning effect, but also do not damage the implant surface, thus providing a safe and reliable tool for oral implant maintenance. In addition, according to a mid-term clinical study conducted by an authoritative stomatological hospital in China, carbon fiber or plastic ultrasonic treatment heads are used for polishing after subgingival ultrasonic scaling, which can improve the effect of scaling.

The existing carbon fiber or plastic treatment head applications are all dental scalers using piezoelectric ceramics or metal magnetostrictive materials as the vibrating body, and the ultrasonic operating frequency range is between 20KHZ and 30KHZ. The principle of ultrasonic scaling is realized by the high-frequency vibration of the ultrasonic scaler. In the process of high-frequency vibration, key components play a very important role, so when selecting materials, it is also necessary to optimize according to product characteristics. , Zhongwei Precision Machinery Co., Ltd. chooses 17-4 stainless steel material not only to ensure the continuous vibration of the product during use, the material is not easy to break, and the hardness is more wear-resistant than ordinary stainless steel. The higher the working frequency, the higher the working efficiency, and at the same time The better the treatment comfort.

The dental ultrasonic treatment device with the highest known working frequency on the market is 41.5KHz, and its working efficiency and treatment comfort are significantly better than the dental ultrasonic treatment device of 20KHz~30KHz. Applying carbon fiber or plastic treatment heads to 41.5KHZ equipment is an effective way to improve doctors' work efficiency and treatment comfort.

Carbon fiber and plastic treatment heads must be fastened to the base of metal-based materials in order to transmit ultrasonic waves. Theoretical research shows that, under the same amplitude, the energy of an object vibrating is proportional to the square of the vibration frequency. When the ultrasound enters the carbon fiber or plastic treatment head from the metal body, it will generate a lot of heat on the contact surface. This heat is related to the operating frequency and the power of the vibration. At the operating frequency of 20KHz~30KHz, the heat can pass through the metal body and be dissipated into the air from the surface of the metal body. At the same time, the scaler sprays a certain amount of rinsing water, which flows over the metal body and the surface of the carbon fiber and plastic treatment heads, which can also take away heat. It can avoid the accumulation of heat on the contact surface, resulting in local high temperature, melting carbon fiber and plastic treatment head. However, under the high working frequency of 41.5KHz, the traditional heat dissipation method cannot dissipate the heat in time. Experiments show that within 5-10 seconds of operation, the carbon fiber and plastic treatment head will cause deformation and failure of the treatment head.
