Description

Laser accelerometer for orthodontics of oral teeth

Technical Field

A laser accelerator for orthodontics of oral teeth relates to the field of orthodontics clinical treatment technology and medical appliances in oral medicine.

Background

Orthodontics in dentistry is the correction of teeth and relief of deformities in patients' teeth, using the plasticity of the jaw, with the aid of correction tools and devices

Applying an external force to the teeth in the misshapen arrangement to move the teeth, the jawThe bone is reconstructed, and finally the purposes of orderly arrangement of teeth and harmonious and beautiful face are achieved. However, the orthodontic treatment of such teeth is long, generally requiring 2 to 3 years or even longer, and therefore, people are always seeking to accelerate the orthodontic treatment.

At present, two application modes are available, one is a mechanical vibration acceleration method, a micro vibrator is held in the mouth of a patient receiving orthodontic treatment by a micro vibrator device, the micro vibrator slightly bites a vibration plate, the vibration plate vibrates with micro amplitude, the vibration frequency is below 60Hz, the representative product in the aspect is an Accelent Aura orthodontic accelerator provided by OrthoAccel corporation in America, but the mechanical vibration type orthodontic accelerator is not widely applied at present, and the effect of the mechanical vibration type orthodontic accelerator is further verified; another way is that since the German scientist Otto Warburg who acquired the Nobel prize in 1931, it was discovered that certain frequencies of light energy stimulate and accelerate intracellular activity, which also underlies the photo-biological regulation therapy in modern medicine. It is known that red light and near infrared light are easily absorbed by human soft tissues, and can activate tissues, promote microcirculation and enhance cell metabolism after being absorbed by the tissues under certain frequency and illumination intensity, so that jaw reconstruction and tooth movement in orthodontic treatment can be accelerated, and orthodontic treatment period can be shortened, which are verified by animal tests and clinical tests; the Laser treatment used for orthodontic acceleration belongs to a Low-energy Laser treatment technology which is called LLLT (Low Level Laser Therapy) internationally, the Laser power used by the technology is in the milliwatt Level to hundreds of milliwatt Level and can reach 500 milliwatt at most, so that the technology is different from the Laser application of Laser scalpels, the cutting is realized by utilizing the thermal effect generated by the high energy density of Laser, and the LLLT technology utilizes the biological effect of the Laser and is a physiological and biochemical effect on the molecular Level; the LLLT technology is already used for orthodontic acceleration, the structure of a pen-type semiconductor laser used in the current oral clinical medicine is similar to that of a common semiconductor laser pen/laser pointer/laser spot position indicator, an internal laser generator, namely a laser diode, is also similar, structurally belongs to the same type of semiconductor device, generally, the laser generator is in the form of a short circular tube, one end of the semiconductor laser is provided with a window for emitting laser, the other end of the semiconductor laser is provided with an electrical pin, the semiconductor laser is similar to a cylindrical semiconductor triode in the form, the laser emission power is from tens of milliwatts to tens of watts, and the driving voltage is from five volts to twenty volts. It is clear that such laser diodes are not suitable for use in low energy laser treatment devices requiring irradiation of a large area, for example, the "renaming pen-type semiconductor oral laser treatment instrument" recently provided by Shenzhen Soxhlet technology, and for example, Sirolase Blue from Denshi Bercinod group (the largest dental material supplier worldwide), which is a single beam laser (containing a near infrared laser). There are many kinds of oral laser treatment devices internationally, and the use history is long, and due to the physical characteristics of laser, one laser generator can only emit one laser beam. This type of laser is very common, not only in the medical field, but also in the hand-held operation where the operating part is a laser emitting "pen", and assuming that an area is to be irradiated, a "scanning" action must be taken, and obviously, a pen-type oral laser therapeutic apparatus can only manually scan and irradiate an area. Assuming that a high-efficiency laser capable of irradiating a large area is used, when a classical semiconductor laser generator and a single-beam laser are used, only an automatic scanning mode can be adopted, and an automatic scanning mechanism is required to be equipped, which is generally complicated, so that the situation is not seen in the field of oral clinical medicine. One key point is that the low-energy laser for laser orthodontic acceleration can be multi-beam laser simultaneous irradiation and area irradiation, and when a semiconductor laser diode is used, a surface mounting device is required, which is not suitable for the structure and the performance of a classical laser diode. Since the surface-mounted devices of the classical laser diodes are extremely rare and simultaneously the complete compliance requirements (low power, low driving voltage, small size, surface mounting) are difficult to achieve, multi-beam laser, area irradiation type low energy laser treatment devices have not been made available, i.e. currently, the devices are specialized for hospitals, no special portable and easy-to-use accelerators of this type are available, patients have to visit hospitals, doctors use lasers to perform irradiation treatment, usually more pen-type lasers are used, and doctors hold the devices to irradiate the parts to be irradiated, which greatly limits the application and the treatment process of patients.
