Embodiments of the present application provide a calibration method and device for dental implant navigation surgery, and a tracking method and device for dental implant navigation surgery. The calibration method comprises: (110) obtaining a position of a scanning area (304) relative to a second visual marker (306) based on a spatial position of a first visual marker (305) disposed on a scanning device (302), a spatial position of the second visual marker (306) disposed on a surgical area (303), and a scanning position of the scanning area (304) obtained by scanning with the scanning device (302); and (120) registering the position of the scanning area (304) relative to the second visual marker (306) with a three-dimensional scene to obtain a transformation matrix, and applying the transformation matrix to the tracking of a surgical instrument. Therefore, the position change of a surgical instrument may be reflected in real time in the three-dimensional scene without implanting a marker point into the body of a patient, even if the patient's head moves during the surgery, thereby accurately tracking the surgical instrument in real time.

A denture is registered and secured to implants with the help of paired surgical-prosthetic implants fabricated based on 3D imaging of the patient's mouth and the denture. The surgical template has guide holes that are located and oriented to guide dental instrumentation forming accurately located and oriented osteotomies for the implants. The prosthetic template conforms to the denture and has guide holes that are located and oriented such that connection holes in the denture can be formed through the guide holes in the paired prosthetic template. The connection holes clear the replacement teeth of the denture and line up with the implants. Attachment elements can be inserted through the connection holes in the denture to secure the denture to the implants.

A method of increasing movement of a tooth in a jaw having at least one tooth with an orthodontic brace thereon includes: (1) holding a handle of a device, the device having an elongate member extending from the handle and a screw tip at a distal end of the elongate member; (2) moving a sleeve along the elongate member to set a length of exposed screw tip; (3) locking the sleeve in place relative to the screw tip; (4) drilling a hole with the screw tip through a cortical bone of a jaw to increase movement of the tooth; and (5) stopping the drilling when the length of exposed screw tip has penetrated the jaw.

A computer-aided method for designing a surgical template for dental and/or orthodontic implants comprises acquiring a first 2D or 3D image of the oral cavity and of the overlying anatomical structures of a patient, processing the first image for defining one or more second 2D images showing corresponding views or sections of the oral cavity, realizing a digital model of the upper dental arch and of the palate of the patient to identify one or more suitable sites for inserting a corresponding implant, selecting one or more slices of the digital model at one or more sagittal or parasagittal planes passing through respective insertion sites, overlapping the slices with corresponding second 2D images for generating a third 2D image, providing a digital library of implants for the selection thereof and for their virtual positioning into the third image in order to allow the adjustment of the inclination and/or the deepness of insertion. A surgical template for dental and/or orthodontic implants suitable to be manufactured with the above method.

In order to improve the reliability of a dental restoration, the present invention provides a method of implanting the dental restoration. The method includes a first operation in which a three-dimensional planning image is generated in which a scanning image overlaps and matches to a computed tomography (CT) image, a plurality of pieces of implantation information of implants are set along a dental arch in the three-dimensional planning image, and an implanting guide device is designed and manufactured, a second operation in which an alveolar bone is flattened by being guided by the implanting guide device, the implants are implanted, and a holder device including a holder abutment and a fixing bar is fixed to an upper side of the implant, a third operation in which a temporary denture is corrected to be occluded between upper and lower jaws to form a temporary mounting portion in which the holder device is inserted into an inner surface portion thereof, a fourth operation in which a corrected scanning image corrected to expose three-dimensional exterior information of the temporary mounting portion to the outside is obtained from a scanning image of the temporary denture, and the three-dimensional exterior information of the temporary mounting portion is replaced and swapped with a virtual holder device, and a fifth operation in which a mount part is formed in an inner surface portion on the basis of the virtual holder device, and an artificial tooth part is fixed to an artificial gum part to which a clip engaged with the fixing bar is fixed so as to manufacture a final dental restoration.

The invention relates to manufacturing a surgical guide to be placed in a patient's mouth. The patient's mouth is scanned to obtain surgical-region scan data at a region where an implant is to be located. The patient's mouth is also scanned in the opened position to acquire dental conditions opposite from the surgical region to obtain opposing-condition scan data. A virtual model is developed using the surgical-region scan data and the opposing-condition scan data. Using the virtual model, a surgical plan is developed that includes the location of the implant to be installed in the patient. A virtual surgical guide is also developed based on the surgical plan. The dimensions of instrumentation to be used with the surgical guide are checked to ensure they will fit within the mouth by use of the opposing-condition scan data. After checking, final surgical-guide manufacturing information is obtained for manufacturing the surgical guide.

Customized dental implants feature enhanced osseointegrable qualities by manufacturing the implant post with osseointegrable material and preparing a larger post body, including a portion to cover a maximized prepared bone surface, to integrate with a jawbone. Resultant implants are more durable and provide a better fit into the oral cavity. Various implant shapes and designs are disclosed. A dental implant may feature a plurality of bone spikes to serve as anchors for the implant in a patient's mouth. Multiple anchors lessen torques experienced by the implant during use. Ideally, the anchors will also project in different axes to maximize osseointegration and strength of the bond between bone and the implant.

A dental implant whereby an osteotomy cavity is formed in jawbone and then a base member of the implant is positioned into the cavity. The base member serves as a platform to secure an abutment member of the implant that in turn receives a dental restoration, such as a crown or denture.
