Methods, devices, systems, and series of appliances are provided for dental implant positioning. One method for positioning an implant with dental treatment includes determining an implant location based on a virtual model of an optimized dental occlusion, moving one or more teeth using a first number of a series of dental appliances, from a first orientation to a second orientation, the second orientation exposing the implant location, placing an implant at the exposed implant location using a landmark included in at least one of the series of dental appliances, repositioning one or more teeth using a second number of the series of dental appliances, from the second orientation to a successive orientation.

Systems, methods and a sensor alignment mechanism are disclosed for medical navigational guidance systems. In one example, a system to make sterile a non-sterile optical sensor for use in navigational guidance during surgery includes a sterile drape having an optically transparent window to drape the optical sensor in a sterile barrier and a sensor alignment mechanism. The alignment mechanism secures the sensor through the drape in alignment with the window without breaching the sterile barrier and facilitates adjustment of the orientation of the optical sensor. The optical sensor may be aligned to view a surgical site when the alignment mechanism, assembled with the sterile drape and optical sensor, is attached to a bone. The alignment mechanism may be a lockable ball joint and facilitate orientation of the sensor in at least two degrees of freedom. A quick connect mechanism may couple the alignment mechanism to the bone.

Systems and methods for determining position and orientation of a bone of an anatomical feature are described. These include the use of a wearable holder configured to be mounted about an outer-skin surface of the anatomical feature, such that the anatomical feature and the bone are positioned in fixed relation with respect to the wearable holder when the wearable holder is mounted about the anatomical feature. Reference marker arrays are fixedly mounted to the wearable holder, each being positioned on the wearable holder to identify a landmark of the bone within the wearable holder when the wearable holder is mounted to the anatomical feature. The position and orientation of the reference markers are trackable to determine position and orientation of the wearable holder in a reference coordinate system, thereby enabling position and orientation of the landmarks on the bone to be determined.

A biopsy marker having a spring-loaded anchor. The biopsy marker includes an insertion orientation and an anchored orientation. The lateral span/cross-sectional area of the marker is configured to change when transitioning between the insertion orientation and the anchored orientation. In an embodiment, the spring-loaded anchor is configured to spring about a predefined rotational axis. An embodiment of the biopsy marker may be comprised of a single wire construction.

According to one aspect of the invention, a system for medical object tracking is provided. The system includes a plurality of radio frequency transceivers where each of the plurality of radio frequency transceivers are configured to emit a radio frequency signal at a respective frequency. The system includes a radio frequency beacon removably attachable to a medical object where the radio frequency beacon configured to: reflect the radio frequency signals from the plurality of radio frequency transceivers, and emit vibration-based signals. The system includes a control device in communication with the plurality of radio frequency transceivers where the control device includes processing circuitry configured to determine a location of the medical object in three-dimensional space based at least in part on the reflected radio frequency signals and vibration-based signals.

A marker coil includes a flexible substrate, a coil formed on the substrate by wiring, and a substrate holding part that is capable of being attached to a testee. A convex shape is formed in one of the substrate and the substrate holding part, and an engaging part for engaging the convex shape is formed in the other one of the substrate and the substrate holding part.

The invention relates to a medical instrumentation with a navigation system which comprises an optical detection unit comprising a camera, and a data processing unit coupled to the detection unit, with a stabilization element of a surgical fixation system and with a medical marking device which is held in a defined spatial arrangement on or is comprised by or formed by the stabilization element, the location and orientation of the marking device in space being determinable with the navigation system, it being possible for at least two images of the stabilization element and the marking device to be taken from a different orientation by means of the detection unit and for the shape of the stabilization element to be determined by the data processing unit on the basis of the two or more images. The invention also relates to a method for determining the shape of a surgical stabilization element.

Various systems, devices, and methods for facilitating efficient anatomical registration in surgical navigation are disclosed. Such systems and devices can have a data collection unit and a scaling device. The scaling device has a main body having an anatomical registration feature defined therein and at least one scaling marker pathway that is selectively oriented with respect to the anatomical registration feature to facilitate repeatable gross placement of a scaling marker relative to a selected anatomical feature. The scaling marker is selectively displaceable along a scaling marker pathway about and between a first end and a second end thereof to fine-tune scaling marker placement prior to image capture.

A marker for identifying a portion of a surgical margin includes a first element to attach the marker to the surgical margin of a surgical cavity located in a body of a patient, and a second element attached to the first element. The second element includes an indicator to uniquely identify the portion of the surgical margin through a radiological scan.

A kinematic connector assembly for kinematically coupling two objects is provided. The kinematic connector assembly comprises a receiver defining a cavity and having a plurality of constraint surfaces accessible in the cavity. The kinematic connector assembly further comprises a key having a triplicity of kinematic elements to repeatably position the key in the receiver. The kinematic connector assembly further comprises a preloading mechanism having a load member movable between a clamped position and an unclamped position to secure the key in the receiver, so that the kinematic elements contact the receiver at the plurality of constraint surfaces such that the key is kinematically constrained to the receiver by being constrained by six points of contact with the receiver.
