A computer-assisted surgical system can include a donor sub-system and a recipient sub-system. The donor sub-system includes a first reference unit having a first trackable element, a fragment reference unit having a second trackable element, and a first detector configured to provide at least one of a first signal corresponding to a detected location of one or more of the first trackable element and the second trackable element. The recipient sub-system includes a second reference unit having a third trackable element, and a second detector configured to provide at least one of a second signal corresponding to a detected location of at least the third trackable element.

A first guide member includes a horizontal body portion and a pair of upright portions. The horizontal body portion has an arcuate configuration and includes a first horizontal surface, a front surface, a rear surface, and a second horizontal surface. The first horizontal surface is flat. The first upright body portion includes a first inwardly extending portion. A first engagement surface of the first inwardly extending portion is configured to rest on a ridge of the alveolar arch of the patient. The second upright body portion includes a second inwardly extending portion. A second engagement surface of the second inwardly extending portion is configured to rest on a ridge of the alveolar arch of the patient. The first guide member lacks a component configured to extend along a lingual or palatal side of the alveolar arch of the patient.

Dental surgical stents can be used to assist a dental surgeon. A hard tissue stent can include an access hole formed in one side and may be placed over one or more of the patient's teeth where the access hole is accurately aligned at a location for drilling to, for example, remove infection. Suction channels may be included in the stent to provide suction about the access hole to remove saliva, water, bone debris and the like, during the surgical procedure. A soft tissue stent may be placed over one or more of the patient's teeth, where the stent can include a mark positioned where the surgeon is to cut to create an access flap in the soft tissue. By keeping the flap attached to the semi-circular window of the soft tissue stent, the surgeon can more easily return the flap to the proper position.

A connector bridge configured to connect between two adjacent surgical guide foundation devices. The connector bridge may include a crossbar portion, two connector pins spaced apart from one another, and wherein the two connector pins extend outward from the crossbar portion in a generally perpendicular direction relative to the crossbar portion. The connector bridge may include a crossbar portion, two openings spaced apart from one another and formed through the crossbar portion, removable bridge pins, and wherein the removeable bridge pins may be configured to be inserted at least partially through the openings.

Provided is a customizable surgical bone-cutting jigsaw puzzle-type guide device. The customizable surgical bone-cutting jigsaw puzzle-type guide device includes: a main guide portion that includes a main contact surface lengthily formed along a required main incision line of a bone to be cut and shaped to be brought into contact with the bone, and a main guide surface forming a guide line together with the main contact surface along the same line as the main incision line and shaped to be brought into contact with a cutting blade for guiding the movement of the cutting blade during cutting of the bone; and a connection portion extending from the main guide portion and connected to a side of the bone such that the main guide portion may be supported on the bone, the connection portion being configured to be detachably attached to the side of the bone.

An implant assembly and its method of use, used in computer-aided orthognathic surgery for properly repositioning a mobile bone segment separated by osteotomy from a malformed mandible, maxilla or chin, the implant assembly comprising fixation bone plates, at least one removable alignment plate for proper pre-osteotomy placement of the implant assembly onto the mandible, maxilla or chin, at least one removable post-osteotomy alignment plate for proper positioning of the mobile bone segment relative to the mandible, maxilla or chin, and a removable cutting guide for guiding the osteotomy saw during separation of the mobile bone segment from the mandible, maxilla or chin.

An orthognathic bone joining or positioning implant method for performing an osteotomy and subsequent rejoining of one or more separated bone sections to the bone in a desired repositioning, wherein the implant is manufactured such that it provides a separating tool guidance contour for separating the bone sections after attaching a first attachment area to the bone, and provides a second or third attachment area for attaching the separated bone sections to the bone in the desire repositioning without detaching said first attachment area. The method utilizes tomographic imaging to produce a target 3D model of the bone showing the repositioned bone sections based on the original 3D model of the bone.

A resection guide can be configured to guide a resection tool toward a graft source or a tissue body. The resection guide can include a resection guide body with at least one opening, and a guide member configured to be at least partially inserted into the at least one opening.

A method and device for ensuring better placement of an implant, such as an implant that is affixed via bone bed drilling to a recipient's skull. In particular, the technology comprises an apparatus and method of deploying the same that can lead to an improved goodness of fit of the implant. The apparatus and process of the present disclosure are particularly applicable to affixing auditory prostheses such as cochlear implants. The implant is provided with a template that has the same dimensions as the implant that is to be affixed. This template has a dye-impregnated material on its distal surface that is used during bone bed drilling to identify bony spots that have to be drilled away to get a flat surface and a better alignment of the implant with the bone bed. The template may also be provided in kit form.

A method for computer-assisted planning of a transplant surgery is provided. The method includes obtaining a computer-readable representation of a donor and recipient skeletal fragment; determining surgical cutting planes on the computer-readable representation of the donor skeletal fragment from which a portion of the donor skeletal fragment from the computer-readable representation of the donor skeletal fragment will be harvested; determining virtual cutting guides; performing a virtual osteotomy to separate the portion of the donor skeletal fragment from the computer-readable representation of the donor skeletal fragment from a remainder portion of the donor skeletal fragment based on a position of the virtual cutting guides that are attached to the computer-readable representation of the donor skeletal fragment; positioning the donor skeletal fragment within a transplant region of the recipient skeletal fragment; and creating a hybrid computer-readable representation comprising the recipient skeletal fragment and the portion of the donor skeletal.
