  • Publication number: 20210401540
    Abstract: Disclosed are an instantaneous dental implant surgery guiding device and a method thereof, of which a main structure includes a base, a receiving space, a sphere, a through hole, and a adjustor. With the above structure, a dentist places the base at a tooth missing site in a patient oral portion, and, after applying glue for fixing, carries out computer-tomographic scanning to allow the dentist to diagnose and assess, and then, the adjustor may be operated to drive the sphere to move in the receiving space in order to change angle and position of the through hole of the sphere, thereby allowing the dentist to apply an implant driller to make a drill along a predetermined route defined by the through hole of the sphere, enabling subsequent operations of expanding the implant route in a bone with drillers of different sizes and positioning the implant.

  • Publication number: 20210068920
    Abstract: A dental forceps structure, including: a fixture body, including an elastic connection portion, two elastic arms formed on two ends of the elastic connection portion, and two bended clamping portions each formed on one end of one of the elastic arms; two accommodation elements, each configured on one of the clamping portions; and two barriers, configured on the respective clamping portions and positioned between the accommodation elements and fixture body, and adapted to isolate the disturbance of surrounding tissues and organs. With the above structure, a user only needs to manually pull the elastic arms apart after placing a water suction element between the accommodation elements and place the clamping portions on the two sides of an affected part, thereby using the elastic force of the elastic connection to contract the elastic arms inward to allow the clamping portions to be naturally fixed on the affected part.

  • Publication number: 20200397533
    Abstract: A dental extraction device includes a gripping assembly including first and second gripping arm, a prying element including a driving arm and an abutting and hooking portion, two first cushioning members defined on the second gripping arm, a first spacing portion formed between the first cushioning members, and a second cushioning member defined on the second gripping arm at one side of the first spacing portion. To extract a tooth, a tooth holding member is first fixed to a tooth to be removed and then the first or second cushioning members are placed on one or more teeth that are not to be removed to serve as a support point and the abutting and hooking portion is set in engagement with the tooth holding member. The first and second gripping arms are then moved to cause the driving arm to drive the abutting and hooking portion for pulling out the tooth.

  • Patent number: 9005899
    Abstract: A method of diagnosing allergic asthma in patients, including the steps of: obtaining from a subject a first sample of peripheral blood immune cells and a second sample of peripheral blood immune cells; adding chitin to the first sample; measuring the average amount of IFN-? in both the first sample and the second sample to get a first value and a second value respectively; and dividing the first value with the second value to get a ratio, wherein if the ratio is smaller than a threshold value, the subject is diagnosed as an allergic asthma patient.
