Systems and methods for augmented reality based surgical navigation
The present disclosure involves object recognition as a method of registration, using a stereoscopic camera on Augmented Reality (AR) glasses or an endoscope as the image capture technology. Exemplary objects include surgical tools, anatomical components or features, such as bone or cartilage, etc. By detecting just a portion of the object in the image data of the surgical scene, the present disclosure may register and track a portion of the patient's anatomy, such as the pelvis, the knee, etc. The present disclosure also optionally displays information on the AR glasses themselves, such as the entire pelvis, the femur, the tibia, etc. The present disclosure may include combinations of the foregoing features, and may eliminate the need for electromagnetic, inertial, or infrared stereoscopic tracking as the tracking technology.
COMPOSITE GUIDE PLATE
The present utility model relates to a composite guide plate, comprising a base guide plate (1) and an implant guide plate (7), or comprising a base guide plate (1) and a repair guide plate (10), or comprising a base guide plate (1), an implant guide plate (7) and a repair guide plate (10), wherein the base guide plate (1) is provided with a retention pin sleeve (2); the implant guide plate (7) is provided with an implant sleeve (8) and a retention pin sleeve fastener (5); the retention pin sleeve fastener (5) is fastened on the retention pin sleeve (2) to connect the implant guide plate (7) to the base guide plate (1); the repair guide plate (10) is provided with the retention pin sleeve fastener (5); and the retention pin sleeve fastener (5) is fastened on the retention pin sleeve (2) to connect the repair guide plate (10) to the base guide plate (1). By means of the composite guide plate provided in the present utility model, the defect of traditional methods whereby the repeated removal and fitting of retention pins and guide plates is required can be overcome. Moreover, all the guide plates can be printed with resin, thereby greatly reducing clinical medical costs and the medical costs of processing plants.
Method of creating an accurate bone and soft-tissue digital dental model
A method of creating a 3-D anatomic digital model for determining a desired location for placing at least one dental implant in a patient's mouth. The method comprises the act of obtaining a first dataset associated with hard tissue of the patient's mouth. The method further comprises the act of obtaining a second dataset associated with soft tissue of the patient's mouth. The method further comprises the act of combining the first dataset and the second dataset to create a detailed structure of hard tissue and soft tissue having variable dimensions over the hard tissue.
Method for manufacturing surgical guide and crown, abutment in mouth for dental implant
Provided is a method for manufacturing a surgical guide, and a crown and an abutment in a mouth for a dental implant, including an operation of obtaining a primarily scanned image through scanning of inner and outer surfaces of a denture which has a first image matching groove matched with a patient's tooth implanting portion and in which a plurality of reference markers are attached to an outside, obtaining a secondarily scanned image through oral scanning of upper and lower jaws while the denture is installed, preliminarily matching the secondarily scanned image with the primarily scanned image, obtaining an integrated scanned image considering a vertical dimension by reversing the first image matching groove so that an image of the first image matching groove is dimensionalized from the primarily scanned image, and obtaining a CT image through CT scanning of the upper and lower jaws.
Accuracy of electromagnetic navigation systems
A system for electromagnetic navigation in dental implant placement may include an electromagnetic tracking system that may be configured to track positions and orientations of a plurality of electromagnetic sensors. An exemplary electromagnetic tracking system may include a field generator that may be attached to a dental unit utilizing a positioning arm. An exemplary system may further include a control unit that may be coupled to the electromagnetic tracking system and the positioning arm. The control unit may be configured to receive the tracked positions of the plurality of the electromagnetic sensors from the electromagnetic tracking system and to adjust at least a position or an angular orientation of the field generator to maintain the plurality of the electromagnetic sensors within a volume of interest within the tracking volume.
GUIDE FOR PLANNING AND DRILLING FOR THE SUBSEQUENT PLACEMENT OF DENTAL IMPLANTS
A guide for planning and drilling for the subsequent placement of dental implants, especially indicated in cases in which angled perforations must be performed in the bone tissue based on a previously performed first vertical hole, and which essentially comprises a support, a plate with an angle at at least one of the ends thereof fastened on the support such that it may move and be detached with respect it, a guide body located at the end of the plate and a rod that in turn comprises an upper end that is joined to the support through rotation that enable the relative movement between both, and a lower end that is inserted in the bone tissue of the patient's mouth.
DENTAL IMPLANT POSITIONING
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.
TWO-STAGE PRECISION GUIDE AND METHOD FOR FIXING TO A LOW-HEIGHT MAXILLARY BONE TRIPOD WITH SHORT DENTAL IMPLANT FUNCTION
A two-stage precision guide and a method for fixing to a tripod with short dental implant function. The two-stage precision guide includes a fixation guide and a drilling guide. In a first stage of use, the fixation guide is adhered to the tripod allowing the body of the tripod, containing five perforations and having three identical feet, to be positioned on the bone. In the second stage of use, once the body has been fixed to the bone, the two-stage guide allows the bone to be worked on using the drilling guide. Once the holes have been made, the two parts of the two-stage guide are removed to be subsequently fixed to the bone by the body. With the feet being placed in the bone, a dental prosthesis can be situated on the tripod thereby allowing the tripod to act as a short dental implant.
Stackable Foundation Guide and Method of Using Same
A stackable surgical foundation guide. The stackable surgical foundation guide may include a body portion having a generally arcuate shape; one or more connector bodies spaced generally about the body portion; one or more fixation ports spaced about the body portion, each of the one or more fixation ports forming a passageway therethrough. The stackable surgical foundation guide may further include at least one stabilization arm affixed to the body portion, the at least one stabilization arm may be configured such that at least a portion of it extends to a top of, or past, a crestal aspect of a residual ridge of an edentulous patient's mouth or behind, or in back of, one or more tooth structures on the crestal aspect of the residual ridge of a dentate patient's mouth. The body portion of the stackable surgical foundation guide may further include a first portion and a second portion that may be coupled together at about a center point thereof in a hingeable manner.
Surgical template
An embodiment of the invention provides a method of producing a surgical template comprising the steps of: obtaining a set of 3D surface data, the 3D surface data representing a surface of a patient's oral situation, obtaining a support structure model describing a surgical template configured to fit to a portion of the surface of the patient's oral situation, obtaining planned bore position data, the planned implant position data describing the longitudinal axes of a set of one or more planned implant bore holes relative to the 3D surface data, automatically modifying the support structure model to provide support material for guide holes in the support structure model corresponding to the one or more planned implant bore holes, producing the dental splint in dependence on the modified support structure model.
