The present invention concerns a surgical device made by computer-aided design and manufacturing (CAD/CAM) and its use as a surgical guide.

The present teachings relate to a method for processing a digital dental impression comprising: displaying an image of the digital dental impression; wherein the image comprises: a shaded region representative of a part of the oral anatomy which is relevant for a dental procedure, and the shaded region being enclosed within a boundary; and an unshaded region representative of a part of the oral anatomy which is not relevant for a dental procedure, wherein the unshaded region and the shaded region are separated from each another by the boundary, receiving user input for altering the shaded region and/or unshaded region; detecting completion of a stroke generated by the user input; altering, the shaded region and/or the unshaded region, in response to the stroke completion. The present teachings also relate to a method for processing digital three-dimensional shapes, a dental procedure assisting system, uses and computer software products.

A custom drill guide and a method, system, and computer readable media for determining a number and location of canals in the tooth in order to create a custom drill guide to match the anatomy for proper orientation of high speed burs and files for cleaning/shaping. By knowing where the canals are located within the tooth, a relatively small access opening may be created, the small access opening provides for a strong crown during the restoration process.

Systems and methods for improved visual prosthetic and orthodontic treatment planning are provided herein. In some aspects, a method for preparing a tooth of a patient is disclosed. The method may comprise building a model of a dentition of the patient including a model of the initial shape of tooth. The method may also include determining a final prepared shape of the tooth. In some aspects, the method may also include generating a treatment plan comprising a plurality of steps to modify the initial shape of the tooth to the final prepared shape of the tooth. The method may also include rendering visualizations for the plurality of steps of the treatment plan. The visualizations may depict the removal of tooth material to modify the initial shape of the tooth to the final prepared shape of the tooth.

A dental restoration device includes a sleeve having an exterior surface and an interior pocket that is at least partially filled with a dental cement, and a crown having an exterior surface and an interior surface that is mated to the exterior surface of the crown and bonded thereto by an adhesive disposed between the exterior surface of the sleeve and the interior surface of the crown.

Disclosed herein a surgical tool set for implant having an implantation driver for implanting a fixture. The implantation driver comprising: a first supporting portion disposed radially in an engagement portion that transmits implantation torque to the fixture; and at least one second supporting portion that is disposed radially in the engagement portion so as to be spacedly apart from the first supporting portion and is arranged asymmetrically with respect to a center point located on a central axis of the implantation driver. The second supporting portion has a larger size than the first supporting portion along at least one of an outer circumference direction and a radial direction of the engagement portion.

Systems and methods of tracking a head of a patient are provided. The system includes a motion tracking system and a head tracker. The head tracker includes a frame, at least one trackable target coupled to the frame, at least one nose pad coupled to the frame, and a pair of adjustable ear coupling members coupled to the frame and shaped for engaging with at least a portion of a back surface of an ear of the patient. The head tracker is configured to apply a clamping force to hold the trackable target in a stable spatial relationship with a location of interest in the head. The motion tracking system includes a sensor for tracking the trackable target and a processor configured for determining a position of the location of interest from the position and orientation of the trackable target and the stable spatial relationship.

A method for referencing a tracking system's coordinate frame to a rigid body's coordinate frame is disclosed. The method involves obtaining a 3D model depicting some of the surfaces of the rigid body. A probe is provided with an affixed tracking reference component. A second tracking reference component is attached to the rigid body. The method involves tracking locations of the probe as it moves along surfaces of the rigid body and then determining a transform that relates the probe locations to the 3D model of the rigid body. In one embodiment the rigid body is a dental mandible or maxilla of a patient and the 3D model is a surface extracted from a computed tomography image of the patient's jaw and teeth.

A dental tool has a body and a working element. The body has a connecting portion and a measuring portion. The connecting portion is disposed on an end of the body. The measuring portion is formed on an external surface of the body opposite to the connecting portion. The working element is connected to the body and has a connecting end and a working end. The connecting end of the working element is connected to the connecting portion of the body. The working end of the working element is connected to the connecting end of the working element and extends out of the connecting portion. The working element of the dental tool provides a detection effect, and the measuring portion of the body provides a measurement effect.

A dental implant guiding tool set and a dental implant guiding sleeve thereof are disclosed. The dental implant guiding tool set includes a handpiece, a dental implant guiding sleeve and a tooth mold fastening device. The dental implant guiding sleeve includes a handpiece head guiding hole disposed axially and corresponding to a shape of the handpiece head of the handpiece, a lateral opening disposed on a side of the handpiece head guiding hole and corresponding to a connection handle of the handpiece. The dental implant guiding sleeve can directly guide the handpiece head of the handpiece, to prevent the dental implant guiding sleeve from directly contacting the drill bit mounted on the handpiece. Therefore, a conventional drill bit can be directly used for a guiding dental implant operation, and the minimal required operation space of the dental implant guiding tool set can be reduced.
