The invention relates to a drill jig (1) for an oral surgery intervention in a patient, said drill jig (1) having a temporary dental device (5) in which a drill guide (3) for guiding a drill in the jaw of the patient is provided, and at least one holding element (4), connected to the temporary dental device (5), for temporarily fastening the drill jig (1) to the set of teeth (2) of the patient.

Provided is a non-incisional dental implant surgical method, and more particularly, a non-incisional dental implant surgical method using a guide pin, whereby a dental implant surgery may be conducted accurately by easily determining an outer shape of an alveolar bone of a patient, into which an implant fixture is to be placed, when forming an implant hole in the alveolar bone and placing the implant fixture in the implant hole to place an implant in the alveolar bone of the patient.

A bone foundation guide system and method, the system could comprise a bone foundation guide comprising a body forming an open surgical space, the body further having a bottom contoured to reversibly affix to exposed bone of a dental surgical site and a top contoured to match a bottom side of a dental implant surgical guide; at least one anchoring strut that removably attaches to the body with an apex of the anchoring strut further denoting an one or more indentations for matching up with and receiving one or more portions of one alveolar ridge that opposes another alveolar ridge supporting the dental surgical site; alternatively to the anchoring struts and a tissue spacing gasket, the dental implant surgical guide that removably connects to the body; and alternatively to the anchoring struts or the dental implant surgical guide, the tissue spacing gasket that removably connects to the body.

A method of producing a retention piece having a guidance package configured to provide a desired movement profile including: obtaining data descriptive of mandibular and maxillary arches, an index position of the mandibular arch at a maximum closure position, and a temporomandibular joint of a recipient; specifying an appropriate guidance package based on the desired movement profile; positioning a retention piece comprising at least a portion of the specified guidance package about virtual representations of at least one of the mandibular and maxillary arches within a virtual articulator; modeling relative movement of the virtual representations of the mandibular and maxillary arches within the virtual articulator; and generating data that can be used by a computer aided machining (CAM) process to create at least one physical retention piece comprising the specified guidance package configured to provide the desired movement profile.

The invention consists of a medical implant for anchoring to the malar process of the maxilla, said implant having a head (1) with an angulation of 35° to 55°; an internal or external connector (2) for different types of abutments; an implant body (3) shaped to define an apical and basal portion, said apical portion being threaded all around, and said basal portion having threads on one side and a faceted canoe-thinning shape on the other side for better layering of soft tissues.

The invention also concerns a medical implant system comprising the aforementioned medical implant, a surgical guide and at least one bone drill.

The invention is suitable for rehabilitation of patients suffering from posterior edentulous maxillae with insufficient bone volume and allows for an immediate rehabilitation of the edentulous patient with a reduced treatment time and morbidity, through a considerably less invasive and technically simplified technique.

A subperiosteal securement kit is provided including a subperiosteal dental implant device and a drilling guide attachable thereto. The subperiosteal dental implant device has a frame engageable with the jawbone of a patient and a fixation bore sized and shaped to receive therein a bone screw. The drilling guide has an elongated guiding channel sized shaped to receive a drill bit therein and is removably attachable to the frame of the subperiosteal dental implant device, with the guiding channel being in communication with the fixation bore when the drilling guide is attached to the frame of the subperiosteal dental implant device. A method subperiosteal dental implant device is provided to be secured to a jawbone of a patient and being engageable with a drilling guide having a threaded section.

The present invention discloses a cavity preparation assembly and a guiding sleeve for immediate implantation in an oral molar region, wherein the guiding sleeve comprises a lower sleeve and an upper sleeve disposed on a top of the lower sleeve, center portions of the upper sleeve and the lower sleeve each has a guiding hole and the guiding holes of the upper sleeve and the lower sleeve are connected, and an axis direction of the guiding hole is a vertical direction; sidewalls of the upper sleeve and the lower sleeve are each provided with a slit passing through the sidewalls, and the slit of the upper sleeve and the slit of the lower sleeve are located on a same side of the cavity preparation guiding sleeve; the upper sleeve is further provided with an installation plate on both sides of the slit, the installation plate is connected to the sidewalls on both sides of the slit of the upper sleeve. The cavity preparation assembly comprises a depth calibration drilling tool and a plurality of guiding sleeves. The present invention not only facilitates observation of the position of the drilling tool, prevent the drilling tool from sliding, but also provides the cooling water channels to cool the drilling tool, avoiding osteonecrosis. The depth calibration drilling tool performs precise cavity preparation according to the preparation depth.

A system and a method are used for assisting a user in a surgical procedure. Three dimensional (3D) positioning information about an anatomical structure of interest and 3D positioning information about a surgical tool are acquired. An augmented reality view of spatial relations between the anatomical structure of interest and one or more positions along a path of the surgical tool is created based on the 3D positioning information. The augmented reality view is displayed superimposed over a field of view of the user. The augmented reality view may be displayed on a head-mounted display. Fiducial markers may be placed near the anatomical structure to provide enhanced positioning information to the creation of the augmented reality view. Operation of the surgical tool may be controlled in view of relative positions of the surgical tool and of a given landmark indicative of the anatomical structure.
