Dental implantation systems and methods are provided, including a system comprising a patient-interacting device having an instrument for preparing a site within a patient's mouth for a dental implant. A guiding device in communication with a fiducial marker engaged with the patient's mouth receives the patient-interacting device, and guides the instrument, relative to the fiducial marker, in conjunction with user manipulation of the patient-interacting device. A controller device including a processor is in communication with the guiding device, and directs the patient-interacting device via the guiding device to prepare the site to receive the dental implant. An engagement sensor is operably engaged with the patient-interacting device and communicates with the controller device. The controller device is responsive to sensed disengagement between the patient-interacting device and the user to direct the guiding device to maintain the patient-interacting device at a minimum vertical disposition. Associated systems and methods are also provided.

An apparatus for implantation of a zygomatic implant in coincidence with an implantation vector includes a dedicated dental tool and a dental implantation guide including a guide shell configured to conform to and to be releasably affixed to a portion of a maxillary bone. The guide shell supports a plurality of guides including an anterior guide and a posterior guide which together form a pair of guides that are distanced apart relative to each other, are configured to be aligned with the implantation vector, and are configured as concave troughs for support of a cylindrical body, the cylindrical body being at least one of the zygomatic implant, the dedicated dental tool, an implantation drill, and a preliminary drill.

Disclosed is a denture tray for visual marking and a manufacturing method thereof. The method comprises: establishing a three-dimensional model of a target dentition of a target patient; obtaining a three-dimensional model of a substrate of a denture tray based on the three-dimensional model of the target dentition; providing a through hole at a preset position on the three-dimensional model of the substrate of the denture tray; establishing a three-dimensional model of a fixed connection portion on an outer side surface of the three-dimensional model of the substrate of the denture tray to form a three-dimensional model of the denture tray, wherein the three-dimensional model of the fixed connection portion is integrally connected with the three-dimensional model of the substrate of the denture tray; and manufacturing the denture tray based on the three-dimensional model of the denture tray.

A series of a palatal expanders increasing width can be used to gradually expand a patient's palate. Each palatal expander may have a palatal region flanked by teeth regions. The palatal region can have a plurality of anchor-receiving features (e.g., anchor interfaces) that allow the palatal expander to be attached to temporary anchorage device anchors that have been implanted into the patient's maxilla.

Aspects of the present disclosure relate to systems, devices and methods for performing a surgical step or surgical procedure with visual guidance using an optical head mounted display. Aspects of the present disclosure relate to systems, devices and methods for displaying, placing, fitting, sizing, selecting, aligning, moving a virtual implant on a physical anatomic structure of a patient and, optionally, modifying or changing the displaying, placing, fitting, sizing, selecting, aligning, moving, for example based on kinematic information.

Disclosed is a dental implant handpiece, comprising an implant handpiece body (1), and a drill bit (2) disposed on the implant handpiece body (1). The implant handpiece body (1) is further provided with an image collector disposed close to the drill bit (2) and configured to acquire images of locations in the vicinity of the drill bit (2) in an oral cavity. In a whole treatment process, a dentist is free of double-handed operation and only needs to hold the dental implant handpiece with one hand. During the treatment process, images near the drill bit (2) are acquired in real time, thus the treatment situation is controlled in real time when each treatment action is executed, and the position and angle of the drill bit (2) may be adjusted at any time according to the images acquired by the image collector.

Surgical systems and methods of controlling a surgical instrument are provided. The system includes a surgical instrument having a cutting portion and a body, the body having a handle, a drive motor for driving the cutting portion in a rotating, a reciprocating or a vibrating motion, a plurality of adjustment motors for adjusting a cutting pose of the cutting portion relative to the handle; and, a controller configured to measure the deviations between the cutting pose and a desired pose of the cutting portion and to activate the adjustment motors to reduce those deviations. The method involves coupling a cutting portion of a surgical instrument to a plurality of adjustment motors; holding the handle of the surgical instrument; operating a controller to measure deviations between a cutting pose and a desired pose; and operating the adjustment motors to adjust the cutting pose relative to the handle to reduce the deviations.

A zygomatic dental implant guide includes a guide body a guide body configured to be secured to a maxillary of a subject, and a guide sleeve coupled to the guide body and configured to receive a zygomatic implant and guide the zygomatic implant toward a zygoma of the subject.

Systems and processes are disclosed for providing rapid and accurate dental prosthetic placement on implant abutments with robotic positioning for coping pick-up processing using a provisional fastener. In an embodiment, a dental arch with an open intaglio surface is bonded onto copings that are mounted onto threaded implant abutments with axially separable fasteners through a pick-up process using the same robotic system used to install the implant abutments into bone. The robotic system may apply movement to the prosthesis to aid its removal from abutments after the copings are bonded. The prosthesis with incorporated copings can subsequently be modified for attachment with definitive screws. One embodiment includes a prosthesis with integral robotic attachment features avoiding imaging of fiducial references for proper placement. An embodiment includes temporary arch indexing features between opposing arches to provide proper occlusion during pick-up processing.

A method of virtually designing a customized healing abutment and a drill guide for a patient, where the method includes: obtaining a CT scan including at least part of the patient's jaw bone; virtually placing at least one implant relative to the jaw bone of the CT scan, such that a planned implant placement is defined; virtually designing: a drill guide for guiding the surgical drilling of a bore for the implant into the patient's jaw bone at the planned implant placement; and a customized healing abutment configured for shaping the soft tissue according to a target profile when arranged in the implant; where the design of the drill guide and of the customized healing abutment is at least partly based on the CT scan and on the planned implant placement.
