  • Publication number: 20230355358
    Abstract: A sinus dental implant includes a main body, an external thread, and a plurality of spiral cutting flutes. The main body has opposite connection end and drilling end. The drilling end has a centered recess surrounded by a drilling zone and communicable with the spiral cutting flutes. The external thread and the spiral cutting flutes are extended in two different spiral directions. The drilling zone is divided by the spiral cutting flutes into a plurality of drilling segments, each of which has two sides located at different heights to thereby include a lower and an upper drilling portion. When the sinus dental implant is implanted into an alveolar hole to contact with a bottom thereof, the lower drilling portions at the drilling end cut the bottom of the alveolar hole slowly, so that the sinus dental implant can drill further in the alveolar hole instead of idling therein.

  • Publication number: 20230210601
    Abstract: A dental implantation assessment method includes the steps of creating a 3D teeth model; setting up a reference line, creating a health status table, and forming a multi-level frame model for an implant placement position on the teeth model; dividing each level of the frame model into a centered implant module and multiple surrounding test modules; dividing each test module into multiple assessment zones, and combining the latter with the health status table; selecting and placing a dental implant model in the frame model, and defining one assessment zone in each test module that contacts with a periphery of the dental implant model as a selected zone; and lastly, computing assessment values assigned to the selected zones to determine an object type of the dental implant model. A dentist can decide an optimal dental implant through dental implant model size selection and implantation simulation to ensure successful dental implant surgery.

  • Publication number: 20230190418
    Abstract: An orthopedic implant includes a main body, which has a downward tapered configuration formed of a plurality of steps of different diametrical sizes arranged along a drilling axis, each of the steps includes a cylindrical and a conical section, and the conical section of the lowest and diametrically smallest step is downward tapered into an apex; an external thread, which is externally formed on the main body to cover all the cylindrical sections but not the conical sections; a plurality of lateral cutting flutes, which are formed on the external thread into the main body and extended from the apex to the diametrically largest step with a spacing distance left between upper ends of the lateral cutting flutes and a top of the largest step. The orthopedic implant can be independently driven into a bone without the need of bone cutting using drill bits in advance and enables good osseointegration.

  • Publication number: 20230085400
    Abstract: An implantation kit including a rotational osteotome and an implant is disclosed. The rotational osteotome includes a plurality of steps of different diametrical sizes, a tip, and at least one flute; and every step includes an annular bottom bevel to provide a cutting edge and recessed section. The implant includes a body having a cylindrical head section and a conical section provided with an external thread and a plurality of spiral flutes. The conical section has a downward tapered profile correspondingly aligned with the recessed sections. The cylindrical head section has a straight cylindrical profile matching that of the step having the largest diametrical size. With the above arrangements, an implant hole on a bone can be formed in only one drilling with one single osteotome for fixedly holding the implant therein. Therefore, the time needed for dental and orthopedic surgeries is largely shortened while better osseointegration can be achieved.

  • Publication number: 20160256235
    Abstract: A digital five-in-one implant surgery auxiliary locator of the invention comprises a massive body formed with a penetrating first guide hole. The massive body has an edge side, on which at least one first fitting portion correspondingly resting against neighboring teeth is disposed, and a bottom portion, on which a second fitting portion having a shape capable of correspondingly embedding with the alveolar bone, is disposed. Thus, the first and second fitting portions can be indeed mounted and fixed onto an edentulous site of a dental implant patient, and the first guide hole prevents a dental implant drill from skidding, so that the dental implant drill can be rapidly and precisely drilled into the alveolar bone and positioned to enhance a proper rate of an implant surgery.
