A bone foundation guide system has a bone foundation guide including a body that is contoured to reversibly affix to a bone segment of a dental implant surgical site. The body is further contoured to guide the cutting of a portion of the bone segment from a dental implant surgical site and alternatively support a dental implant surgical guide. The body is further contoured to support a bone foundation guide prosthesis as an alternative to the dental implant surgical guide. The bone foundation guide prosthesis combines with the body to accommodate the bone segment portion as placed through the body prior to the bone segment portion being removed from the dental implant site through the use of the body.

A dental prosthesis having a guide hole formed therein. The guide hole is configured to guide placement of a dental implant, and configured to receive the implant, holding the prosthesis in place when screwed into the bone of a patient. This may allow for the simultaneous placement of both dental implant and dental prosthesis, rather than the current state of the art which requires a long waiting period between implant placement and prosthesis placement.

Ablation probe tips (108, 148, 320, 360) and physical and virtual stents (110) for use in tooth bud ablation procedures that result in tooth agenesis as well as tooth bud ablation methods are described herein.

A guide for placement of a dental implant. The guide may comprise a guide pin sleeve, a drill guide sleeve, and a frame structure. The guide pin sleeve may be configured to be inserted over a parallel guide pin. The drill guide sleeve may be configured to receive at least a portion of a drill. The frame structure may be configured to couple the drill guide sleeve to the guide pin sleeve at a particular distance from the guide pin sleeve and at a particular angle with respect to the drill guide sleeve.

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 invention related to a method for planning a dental structure, in which a 3D model of the structure, with at least one radially symmetrical aperture, is already provided.

On the basis of the 3D model of the structure that is already provided, an axis of symmetry of the at least one radially symmetrical aperture of the structure is determined in relation to said 3D model.

A custom surgical stent for use in a tooth bud ablation procedure that results in tooth agenesis.

A fixation pin for fixing a dental drill template. The fixation pin has a head having a bearing surface that is intended to bear at least partially on the drill template, or a sleeve provided in the drill template. The fixation pin has a rod having a shape of an essentially circular cylinder and extending from the bearing surface at an essentially right angle. The rod is intended to be inserted into the drill template or the sleeve provided in the drill template.

An intraoral 3D scanner includes a probe light source configured to generate a probe light such that the probe light is transmitted towards the dental situation; a camera including an array of sensor elements, the camera being arranged such that the probe light from the dental situation is transmitted to the array of sensor elements, wherein the camera is configured to create images of the dental situation from which a point cloud is generated, and a guiding system configured to guide relative movement of the intraoral 3D scanner towards the dental situation, wherein the camera is part of the guiding system, the camera is configured to record images from which a relative position of the intraoral 3D scanner and the dental situation is determined, such that based on the relative position, the guiding system is configured to provide a positioning signal in the form of a positioning color code.

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.
