What is the difference between manually-tuned and auto-tuned?

The first ultrasonic dental instruments of the periodontal instruments are manually tuned, which means that the frequency can be controlled and can be controlled and water. Today most units are automatically tuned, which means that the frequency is the highest efficiency of automatic adjustment. Frequency is converted to the number of vibrations per second. For example, when a magnetostrictive tip is marked as 25 KHz or 30 KHz, this means that the tip vibrates at 25,000 times per second (CPS) or 30,000 CPS. As a result, in an artificially tuned unit, the operator can control the number of times the tip touches the calculus/debris. The more advanced exposure to calculus/debris, the greater the chance of removal. In artificially tuned units, it can reduce the frequency, reduce hard stones, maximize the patient's comfort level, and may reduce the adverse effects of measuring instruments on the root surface.
Prior to preparing the ultrasound device for patient care, the operator adjusted the water and power until the spray was sprayed on the top to form aerosols. Today, a heavy or light mixing mixture is recommended for light debris removal and regret. This flow is still sufficient to satisfy continuous irrigation, cooling, cavitation and irrigation, while reducing the production of aerosol mist.
How does amplitude affect ultrasonic instruments?
Clinicians often mistake frequency for strength. The power behind the ultrasound machine is not determined by the frequency, but by the combination of frequency and amplitude. Where the frequency control vibrates, the amplitude determines the length of the stroke or the length of the vibration. The larger the amplitude, the greater the spread of the tip. High power means longer, more powerful strokes, while low power equals shorter, weaker strokes. An analogy of this concept is that a ball and a crane are ready to demolish a building. If the ball is only a few feet away from the building before it touches it, it won't be very strong. Before the swing, the farther away the ball is from the building, the bigger its bursting force. The power control knob on the ultrasonic device can adjust the tip amplitude. When heavy and/or tenacious stones appear, increased strength will be more effective.
When choosing a powerful ultrasonic calibration device, pay attention not only to the high frequency but also to the amplitude range of the unit. In order to meet the power Settings of different tasks, the ideal equipment will have wide range.
The difference between magnetostriction and piezoelectric
The results of the analysis of the magnetic striction and piezoelectric units are analyzed. Some studies have shown that piezoelectric ultrasound makes the root surface smooth and increases the comfort of patients, while other studies have found that rough roots and increased patient discomfort with the device. Both magnetostrictive and piezoelectric units are designed with various inserts and prompts, and seem to be equally effective in removing calculus.
Piezoelectric ultrasonic elements claim to generate less heat than magnetostrictive units in the dental equipment. Although water reduces tip friction and promotes irrigation, its flow can be minimized. Other claims include piezoelectric units that are more efficient in computing because of the stronger vibrations on the surface of the teeth.
Some piezoelectric units require a torque tool to ensure and remove tips from the handpiece. During treatment, this requirement may be more damaging than changing magnetostrictive techniques. The piezoelectric unit does not affect the pacemaker, because the energy is generated by the ceramic crystals without producing a magnetic field. They are widely used in Europe and Asia.
The team's clinical research partners are consumer reports on dental products and technologies. A 2003 newsletter reported that there were 11 ultrasonic scalpers in the United States. The report details the best performance, cutting-edge design trends, and methods to optimize scaler performance. As long as the frequency is the same, the wide selection and interchangeable insertion of the magnetostrictive scalar between the brand is recognized. Unit type - magnetostriction and piezoelectric ceramics are not found in some units of the two groups. Performance recommendations include: suggest replacement frequency with use consistent, use a larger diameter tip toughness, and use better hints to improve touch and better contact.
