It took 6 years to build "China Pride" and broke through many problems in this field.
Oral ulcers, lip scratches, food hung, easy to fall off... These problems that plague patients with orthodontics (cuffed) are finally solved in the unremitting efforts of Dr. Geely and the team at the First Affiliated Hospital of Sun Yat-sen University. It is.
On May 6th, Dr. Geely's Euro-European medical team held a new ball-tooth correction conference in Washington, DC. The 2mm aligner was designed to be hemispherical and built into the device to solve dozens of engineering problems in orthodontics. problem. It is reported that this product is a completely independent research and development of new products, has more than 60 invention patents at home and abroad.
Nearly 3 million orthodontic demanders suffer "beautiful pain"
The data shows that there are nearly 3 million patients with orthodontic needs in China, and 95% of patients are using traditional braces with steel wire wrapped around metal brackets.
Such a aligner can correct the teeth, but since all of them are square brackets and the surface structure is not smooth enough, there are many problems such as scratching the mucous membrane of the lips and easily falling off.
Therefore, "People who wear braces, doctors will basically tell them that it is normal to have oral ulcers in the first two weeks, because this is an inherent defect of traditional brackets, and doctors have no way to solve them." Team leader Dr. Geely introduced Regardless of the traditional ligature brackets and self-locking brackets, due to the complexity of the surface structure, there are various grooves and holes and cracks. The patient's lips and teeth will have tens of thousands of activities every day, which will make the patient's lips and teeth feel very uncomfortable. In addition, it is difficult to clean, easy to hide dirt, and very bad for the health of the gums; of course, it is easy to eat. Hanging food; even more so, these complicated structures will cause the volume of the bracket to become thicker, so that the corrective force is not as good as before, tens of thousands of collisions with the object every day, it will make the bracket easy to fall off, and it will also affect the correction. effect. "In the clinic, almost every patient has one or two brackets in the correction cycle for two years. If the patient does not pay attention to eating hard food, there will be more."
New invention, great surface, no correction device
With the birth of the first spherical orthodontic device, the engineering and technical problems that have plagued the orthodontic appliance for nearly a hundred years have been solved. After more than six years of research and development, Dr. Geely has finally successfully launched the ball holder, which is the only spherical self-locking orthosis in the world.
What is amazing is that this 2 mm large spherical bracket does not have any corrective device on the surface, and it feels like a complete and smooth one. According to reports, this is because the team built all the equipment such as wire into this small semicircle. Among them, there is only one small 0.3mm thick cover plate with a 5-layer structure inside. In addition, the cover plate of the surface is not a whole, but is welded seamlessly by a plurality of blades.
According to reports, such a spherical bracket will not scratch the mucous membranes of the lips, and there will be no more food hung. Because of the smooth surface, it is also very easy to clean. The design of the spherical orthosis is that the spherical bracket is less stressed than the square bracket, and the ratio of the two off-rates is about 1:20.
In addition, the original two kinds of tiny screws create a lock-and-trap system that opens up a new era of orthodontics. This marks the entry of the bracket into the mechanical age, the doctor can better control the movement of the teeth during the correction process, and the treatment plan will have many options.
Ravindra Nanda, professor of orthopaedic science in the field of orthodontics in the field of orthodontics, said that the ball is a very meaningful system, creating a new orthodontic biomechanical model, changing The history of fixed appliances. Professor Dr Andrews, the inventor of the straight wire appliance system, said that the ball-correction system brought innovation and change to orthodontic medicine.
Threading on the bracket is a world-class blank
The product is even more amazing, and it is far more than that.
According to reports, in the entire spherical bracket system, it is necessary to make a thread on the bracket. This is a world-class blank. There is never a bracket manufacturer at home and abroad who dares to try this way. Make a precision on the spherical bracket to 0.001. The millimeter thread has a screw hole size of only 0.3 mm and is above the spherical bracket.
"On the 2mm ultra-small structure, the brackets have tens of thousands of dotted groove cracks and other structures, and it is very difficult to rotate the threaded holes on the mold. This is very difficult." But in the end, the team It still solved this problem and also produced several domestic and international patents.
