A bone foundation guide system having a bone foundation guide with a foundation guide body forming an open surgical space connecting a top of the bone foundation guide body with a bottom of the bone foundation guide body, the bottom contoured to removably affix the bone foundation guide body to the bone of a dental implant surgical site, the body further contoured to guide the cutting of bone from a dental implant surgical site and supporting a dental implant surgical guide; the dental implant surgical guide contoured to removably mate to the bone foundation guide body; wherein a combination of the bone foundation guide and the dental implant surgical guide forms a double open-ended placement channel that passes through a plurality of guiding cylinders held in tandem alignment to aid in the placement of a dental implant that is anchored in a site remote from the mouth.

A retainerless orthodontic dental implant system for positioning the mandible forward relative to the maxilla and for facilitating optimal airflow during sleep and a method of using such a system.

The present disclosure discloses a bite controlled drill-head guide plate and a manufacturing method. The guide plate includes an upper matrix controlled by an upper tooth, and an upper alveolar bone or mucosa, and a lower matrix controlled by a lower tooth, and a lower alveolar bone or mucosa; a support body is disposed between the upper matrix and the lower matrix; and a control mechanism for positioning and guiding an implant drill-head is disposed on the support body, the upper matrix or the lower matrix. When in use, the guide plate is placed between upper and lower teeth of a patient, and is fixed by enabling the upper and lower teeth to respectively bite the upper matrix and the lower matrix; and then, the drill-head is placed into the control mechanism that is set according to implantation data, and the drill-head is moved to an alveolar bone along a direction of the control mechanism in implant drilling. Since the guide plate guides and positions the drill-head, the positioning and guiding accuracy is improved, the guide plate is prevented from contacting with a high-speed rotating drill bit directly, and the additional heating amount of the drill bit is not increased. The guide plate can be fixed only by biting of the patient, so that the multi-person operation in tooth implantation work turns out to be unnecessary, and the operation difficulty in tooth implantation is reduced.

The present invention discloses a method for fixing a dental implant hole preparation mechanism and a teeth-biting adjustable-control drill bit guide plate. The method for fixing the dental implant hole preparation mechanism includes: placing the dental implant hole preparation mechanism into an oral cavity first and then getting the dental implant hole preparation mechanism fixed by biting upper teeth and lower teeth jointly. The fixation of a guide plate is implemented by teeth biting of an implant object, so that the fixation difficulty is reduced, and the poor fixation precision and the stability are improved. The teeth-biting adjustable-control drill bit guide plate for implementing dental implant hole preparation includes upper and lower biting plates controlled by upper and lower teeth, and an adjustment mechanism for adjusting the upper biting plate and the lower biting plate multi-directionally. When the teeth-biting adjustable-control drill bit guide plate is used, positions of the upper and lower biting plates are adjusted, so that an implant handpiece drill bit is consistent with a designed implant prepared hole in direction after teeth biting fixation, thus implementing accurate control on an implant handpiece; and as the adjustment to the position of the implant handpiece is achieved by adjusting the positions of the upper and lower biting plates, the teeth-biting adjustable-control drill bit guide plate can be adapted to different dental implant positions only by replacing a tooth die or an alveolar bone die; and therefore, not only is the universality of the guide plate improved, but also the manufacturing time of the implant guide plate can be reduced.

Disclosed is a method for scanning an edentulous patent who has a denture, where an impression material arranged at the gum-facing surfaces of the dentures is shaped by the patient's gums and both the teeth side and the gum-facing surface of the denture is scanned and the obtained digital 3D representations are used to determine the relative arrangement of the patient's edentulous jaws in a bite determined by the dentures.

A surgical template for the placement and installation of a dental prosthesis is provided. The surgical template comprises a framework connectable to a patient's mouth, a drilling template connectable to the framework, and a dental prosthesis connectable to the framework. The drilling template allows customized and guided drilling for placement of implants, and the dental prosthesis comprises openings which align with the drilling template guide holes, allowing directed placement of the implants through the dental prosthesis openings. In many embodiments, the implant is able to engage with both the bone of the patient and the dental prosthesis simultaneously, thereby anchoring the prosthesis to the bone of the patient.

A system for preventing injury to inferior alveolar nerve caused by dental implant drills during a dental implant surgery. The system includes a dental implant drill, a clamp, an ohmmeter, a first wire, a second wire, and a processor. The dental implant drill is configured to make a hole in a mandible of a patient. The clamp is configured to be attached to a lower lip of the patient. The ohmmeter is connected to the dental implant drill and the clamp. The processor is configured to receive the measured electrical resistance between the dental implant drill and the clamp from the ohmmeter and turn off the dental implant drill by sending commands associated with turning off the dental implant drill to the dental implant drill when the measured electrical resistance between the dental implant drill and the clamp is less than a predetermined threshold.

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.

A partially customizable single-piece dental implant includes a preformed bone-anchorage component and an abutment component that is custom milled from a block either preoperatively, (i.e., Process A) or intraoperatively, (i.e., Process B). In Process A, the planned abutment shape is designed by a computer-aided design (CAD) software based on a computerized tomographic scan and other patient data. Alternatively, under Process B, the position of the planned implant with respect to the alveolus is digitally captured (e.g., by an optical impression device or an intraoperative computerized tomographic scan). In both Process A and Process B, a blank implant having the millable block is held to allow a computer-aided manufacturing (CAM) machine to customize the abutment component, as well as part of the bone-anchorage component. The resultant dental implant is then inserted in the alveolus and either a provisional or permanent prosthesis can then be immediately loaded on the implant.

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.
