  • Patent number: 11612453
    Abstract: A dental implant guiding tool set and a dental implant guiding sleeve thereof are disclosed. The dental implant guiding tool set includes a handpiece, a dental implant guiding sleeve and a tooth mold fastening device. The dental implant guiding sleeve includes a handpiece head guiding hole disposed axially and corresponding to a shape of the handpiece head of the handpiece, a lateral opening disposed on a side of the handpiece head guiding hole and corresponding to a connection handle of the handpiece. The dental implant guiding sleeve can directly guide the handpiece head of the handpiece, to prevent the dental implant guiding sleeve from directly contacting the drill bit mounted on the handpiece. Therefore, a conventional drill bit can be directly used for a guiding dental implant operation, and the minimal required operation space of the dental implant guiding tool set can be reduced.

  • Patent number: 11234791
    Abstract: An approach is disclosed that involves creating an updated master dental model of a patient's mouth after an implant surgery by aligning new postoperative oral scan data to pre-existing preoperative oral scan data. Before surgery a multi-piece stackable surgical guide set is created using the preoperative oral scan data. The surgical guide set is used to facilitate the surgery. After the surgery at least one piece of the surgical guide set is placed back in a patient's mouth and acts as a reference marker because it was created using the preoperative oral scan data, but is also part of the postoperative mouth configuration since it was used to facilitate the surgery. The affected portion of the mouth is digitally scanned by way of a physical impression with the reference marker in place to determine the new characteristics resulting from the surgery such as new implant installation locations and orientations.

The diameter (d41) of the drilling head portion (41) is larger than the inner diameter (d2) of the guide sleeve (2) and the spindle is of smaller diameter, such that the association of the drill (4) to any of the guide sleeves (2) can be performed only by inserting the spindle through a gingival side of the sleeves. Upon association of the drill with the sleeve, the drilling head (41) protrudes from the gingival side (2G) thereof. The surgical guide has a void (100) accommodating the drilling head (41) of the drill.

  • Patent number: 9039414
    Abstract: According to one embodiment, a dental implant system for implanting a dental implant in bone tissue using an implant drill driver includes a shank and a drill guide. The shank is removably coupleable to the implant drill driver and includes an internal passage that has a non-round cross-sectional shape. When coupled to the implant drill driver, the shank is rotatable via operation of the implant drill driver. The drill guide pin includes a bone penetrating end portion and a shank engagement portion. The shank engagement portion includes a notched section having a non-round cross-sectional shape corresponding with the non-round cross-sectional shape of the internal passage of the shank. The notched section of the shank engagement portion is insertable within the internal passage of the shank. Moreover, engagement between the notched section and the internal passage facilitates co-rotation of the shank and drill guide pin.

  • Publication number: 20150140507
    Abstract: Drilling of an implant shaft is carried out with a handpiece tool whose location and angular orientation with respect to a radiographic working guide is updated in real time with respect to the radiographic working guide and anatomical structures of the patient, free of viewing obstructions. Prior to the drilling, the radiographic working guide is fitted to a particular patient. Real-time imaging support is provided on a display of a computer, wherein the radiographic workpiece guide includes a plurality of fiducial markers that define a substantially planar reference surface of the radiographic workpiece guide. The radiographic workpiece guide also includes an alignment structure located a predetermined distance from a pilot hole proximate the work site. The image is updated based on an initial radiographic scan and updated position information from the handpiece tool as to location and angular orientation of the handpiece tool relative to the workpiece guide.
