A dental implant surgical guide includes a body having a buccal wall and a lingual wall that is continuously connected by a first end and second end forming an open surgical space connecting a top of the body with a bottom of the body. The bottom is further contoured to receive and rest upon at least a portion of a bone segment of a respective patient's alveolar ridge to guide the surgical alteration of a respective patient's alveolar ridge. The dental implant surgical guide is capable of locating and securing one or more implants upon the respective patient's alveolar ridge. The dental implant surgical guide fits upon the top, the top being contoured to receive and support the dental implant surgical guide.

A hand-held surgical device, particularly for use in oral surgery, includes a rotatable tool, a head of the tool having a hollow-cylindrical design, and an active region, particularly for machining bones, being arranged at a distal edge of the head. A protection device is arranged which partially surrounds the distal edge of the tool and in some sections extends in the axial direction beyond the distal edge such that only a circular arc of the distal edge serves as the active region. The protection device may have a connecting element for detachably securing to the hand-held surgical device.

Various embodiments described herein generally relate to apparatuses and methods for performing bone implants such as, but not limited to, dental implants, knee and joint replacements, and various types of bone anchored prosthesis. For a better understanding of how the various apparatus and methods can be used for bone implants, an example will be given herein with respect to dental implants.

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 that is more comprehensive (e.g., it includes bite registration). 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 may act 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 may then be digitally scanned directly or indirectly 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 new postoperative oral scan data may be combined with the pre-existing preoperative oral scan data by way of the reference marker (since it is a constant between the two sets of scan data) without having to do such things as take a new bite registration, on which a new implant restoration can be easily created.

According to an aspect of some embodiments there is provided a bone anchor including an elongated core having a tip at a distal end and coupled to a head at a proximal end, and a segmented helical thread defining one or more gaps therein, each gap defining at least a trailing wall, the trailing wall having a cutting surface including at least one cutting edge. The bone cutting surface and the cutting edge configured to cut bone and guide bone fragments radially inwards. According to an aspect of some embodiments there is further provided a bone anchor kit and a method for implanting the bone anchor in bone.

A bone foundation guide system for a dental implant surgical site has a bone foundation guide and a dental implant surgical guide with an open surgical space therebetween. The top of the foundation guide body is contoured and has an upper surface to attach a bottom surface of the dental implant surgical guide as well as to define a removal and augmentation level and to guide the removal and/or augmentation of bone segments from the dental surgical site via a separation plane. The separation plane has a central area predetermined to define an implant depth of bores for anchoring implants, and further has an inclined area extending from all side ends of the central area towards the first bridge end and the second bridge end raising above the removal and augmentation level of the jaw bone.

A custom implant fixture which comprises a first fixture part having a first transverse section determined by a shape covered by an alveolar bone of a tooth to be extracted; and a second fixture part formed so as to extend from the first fixture part, determined from the position and the direction of a root portion of the tooth with respect to the alveolar bone, and having a second transverse section.

Disclosed is a method of manufacturing a digital overdenture. The method includes a first operation of aligning and setting a plurality of pieces of implantation information of fixtures according to alveolar bone information in a planning image, a second operation of designing and manufacturing a surgical guide and a holder abutment mounting guide, a third operation of preparing a temporary denture corrected to form a temporary holder insertion portion having an inner surface part into which a holder device is inserted to be shape-matched therewith, in which the surgical guide is installed in the target arch to implant the fixtures and the fixing bar is fixed to the holder abutments moved to and coupled with top ends of the fixtures by the holder abutment mounting guide, and a fourth operation of manufacturing a digital overdenture including an artificial tooth portion and an artificial gum portion.

A system and method for a tracker arm mount for dynamic navigation is provided. The tracker arm mount accurately adapts to the patient's jawbone and is temporarily secured to the bone with screws engaging the full thickness of the bone. The tracker arm supports an occlusal positioning device and a dental prosthesis. The tracker arm mount is based off digital imaging records. The inner surface is fabricated to closely contour the outer surface, or buccal, contour of the patient's jaw bone. Attachment apertures avoid vital structures and may accept reinforcement collars. Fasteners are placed through the attachment apertures to fixate the mount to the patient's jaw bone. Slots accept corresponding tabs from an occlusal positioning device, interim dental prosthesis, or other device.

In various examples, a dental and medical loupe system for lighting control, streaming, and augmented reality (AR) assisted procedures is provided. Facial recognition algorithms and/or inertial measurement unit (IMU) sensors may be used to determine when a light disposed on eye-glasses of a wearer should be activated. As a result, instead of requiring a medical practitioner to manually turn on and off the light source, facial recognition may be used to determine when the dentist is looking toward a face of a patient, and to turn on the light when a face is present and off when a face is not present. In addition, some examples leverage augmented reality (AR) functionality to overlay patient and procedure information on one or more lenses of eye-glasses worn by a practitioner to allow for an un-occluded view of the actual location where the procedure is being performed.
