A method of enabling a control of an orientation of a tool, particularly a dental drill, in relation to a work part, particularly a jaw, is disclosed. The method includes mounting a work part inertial system unit stationary to the work part; mounting a tool inertial system unit stationary to the tool; obtaining a digital image of the work part; defining three reference spots on the digital image of the work part wherein the three reference spots are distant from each other and stationary in relation to the work part; defining a target orientation of the tool on the digital image of the work part wherein the target orientation is definite with respect to a reference plane comprising the three reference spots; and referencing the tool inertial system unit to the three reference spots of the work part.

The invention relates to a screw, a tool and a system for dental implantology, forming a fixing system and the components thereof to be used in a dynamic pillar assembly. Said dynamic pillar assembly is used in the production of prostheses on dental implants in human implantology in order to fix screws at an angle.

A milling cutter and guide piece, the milling cutter including an elongate shaft extending along a longitudinal axis and a distal end portion having a milling part including at least one circumferentially disposed cutting edge for removing bone tissue, the guide piece having a fixation element, for releasably fixing the guide piece to a support structure, and a longitudinal axis, wherein one of the guide piece and the distal end of the milling cutter includes a head having a central axis coaxial to the longitudinal axis of the one of the guide piece and the distal end of the milling cutter, and the other of the guide piece and distal end of the milling cutter includes a inner cavity extending along a central axis coaxial to the longitudinal axis of the other of the guide piece and the distal end of the milling cutter.

The subject matter of the instant invention relates to a dental implant surgical apparatus and system comprising a customized dental ridge augmentation matrix and one or, optionally, a plurality of dental implant surgical drill guides, and methods of use thereof.

A method may include obtaining a digital preoperative dental model of a patient, designing a guide appliance set on the digital preoperative dental model according to a surgical plan for the patient, and storing the design of the guide appliance set in a computer-aided manufacturing (CAM) compatible file format. Designing the guide appliance set may include designing a base frame configured to engage an oral structure of the patient without obstructing a planned surgical site region of an alveolar ridge, designing an uppermost surface of the base frame to, at least in an area adjacent to the planned surgical site region, terminate below the alveolar ridge when the base frame is engaged with the oral structure, designing at least one attachment that is releasably attachable to the base frame, and designing the at least one attachment to be fully received in a mouth when attached to the base frame.

Implant supported restorations have proven to be a predictable option for replacing missing teeth. In cases of inadequate quantity of bone, the bone volume can be increased by bone augmentation procedures. Several factors can affect bone regeneration, one of those is the morphology of the defect at the implant site. A defect surrounded by bony walls (an intra-osseous defect) is known to yield a highly successful regeneration. The purpose of this retrospective case series study was to present a new step-by-step surgical procedure known as the Custom Alveolar Ridge Splitting (CARS) technique for maxillary anterior ridge augmentation. This technique creates an intra-osseous defect while splitting and augmenting an atrophic ridge. Sixteen consecutive cases were treated with the CARS procedure. All cases were effectively treated with successful implant placement. All implants were restored and followed for twelve to twenty-four months after loading. According to this retrospective study, the CARS procedure is simple, successful, and predictable, and may be used as a surgical option for horizontal alveolar ridge augmentation in the anterior maxilla. A highly useful trephine bur design is also provided by this invention, especially useful for forming a green fracture to form walls to hold and support the bone graft material.

A bone foundation guide system and method, the system could comprise a bone foundation guide comprising a body forming an open surgical space, the body further having a bottom contoured to reversibly affix to exposed bone of a dental surgical site and a top contoured to match a bottom side of a dental implant surgical guide; at least one anchoring strut that removably attaches to the body with an apex of the anchoring strut further denoting an one or more indentations for matching up with and receiving one or more portions of one alveolar ridge that opposes another alveolar ridge supporting the dental surgical site; alternatively to the anchoring struts and a tissue spacing gasket, the dental implant surgical guide that removably connects to the body; and alternatively to the anchoring struts or the dental implant surgical guide, the tissue spacing gasket that removably connects to the body.

A computer-based method and system of virtually planning a dental restoration in a patient are disclosed, including steps, units or code segments for virtually planning a first dental restoration. First production data is based on the planned first dental restoration for production thereof or of a product related to a medical procedure for installing at least a portion of the first dental restoration in an oral cavity of the patient. Scan data is provided including factual position data and/or factual shape data based on the first dental restoration when at least partly installed in the oral cavity of the patient. The second dental restoration is virtually planned, including adjusting the planned first dental restoration in dependence of the scan data. Second production data is provided based on the planned second dental restoration useful for production of the second dental restoration.

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.

A dental device is described. The dental device includes a surgical template having one or more sites for drilling osteotomies in the maxillary or mandibular jaw and a false teeth set. The surgical template and false teeth set are configured to fit together to form a denture prosthesis that can be implanted in a patient. Also described are a method for creating a surgical dental template, a method for implanting a dental prosthesis, and a method for reducing jaw bone in a patient.
