A cavity preparation assembly and a guiding sleeve for immediate implantation in an oral molar region, wherein the guiding sleeve comprises a lower sleeve and an upper sleeve disposed on a top thereof, center portions of the upper sleeve and the lower sleeve each has a guiding hole and the guiding holes are connected; sidewalls of the upper sleeve and the lower sleeve are each provided with a slit therethrough; the upper sleeve has an installation plate on both sides of the slit, the installation plate is connected to the sidewalls. The cavity preparation assembly comprises a depth calibration needle and a plurality of guiding sleeves. The present invention not only facilitates observation of the position of the needle, prevent the needle from sliding, but also provides the cooling water channels to cool the needle, avoiding osteonecrosis. The depth calibration needle performs precise cavity preparation according to the preparation depth.

The present invention relates to a device and method for processing an image for generating a design image based on a reference marker. A method for processing an image for generating a design image based on a reference marker includes receiving, from at least one external device, a computerized tomography (CT) scan image and a plurality of oral scan images related to a person to be treated who has a plurality of reference markers attached to an inside of an oral cavity, generating a registered image by registering the images on the basis of locations of the plurality of reference markers detected from the images, determining, on the basis of the registered image, a teeth profile related to the inside of the oral cavity of the person to be treated, and generating a design image related to the inside of the oral cavity on the basis of the teeth profile.

An image generation system for implant diagnosis includes a first image information acquirement apparatus acquiring first three-dimensional (3D) image data about a mouth area of a target patient, a second image information acquirement apparatus acquiring second 3D image data by scanning plaster patterns of teeth of the target patient, and a data processing apparatus receiving and matching the first 3D image data and the second 3D image data and generating synthetic 3D image data. In the image generation system, the plaster patterns of teeth are provided with a matching reference marker for matching the first 3D image data and the second 3D image data, and the data processing apparatus pre-matches the first 3D image data and the second 3D image data based on a coordinate of a matching reference marker of the second 3D image data.

There is disclosed a jig device that can be used for processing a dental implant surgical guide. According to an aspect of the invention, there is provided a jig device for processing of a dental surgical guide, the jig device including: a base at which a surgical guide having an impression acquired in an oral cavity of a patient is disposed; a fixing unit which is provided at the base and at which one side of the surgical guide is seated; and a cover unit which allows the surgical guide to be disposed between the fixing unit and the cover unit and is formed to be openable and closeable so as to fix and/or unfix the surgical guide.

The present invention relates to a dental device (1) for removing a dental implant (2) which is at least partially or fully osseointegrated with a patient's jaw (3), comprising: a head portion (6) for rotatingly holding a dental tool (7) for unscrewing the dental implant (2); and a driving means for applying a torque to the dental tool (7) for unscrewing the dental implant (2); characterized in that the driving means is further adapted to apply pulsed torques (; .sub.1, .sub.2, .sub.3) to the dental tool (7) to unscrew the dental implant (2).

A dental implant surgical guide and includes a body having a buccal wall and a lingual wall that is continuously connected by a first end and second end forming an open surgical space connecting a top of the body with a bottom of the body. The bottom is further contoured to receive and rest upon at least a portion of a bone segment of a respective patient's alveolar ridge to guide the surgical alteration of a respective patient's alveolar a ridge. The dental implant surgical guide is capable of locating and securing one or more implants upon the respective patient's alveolar ridge. The dental implant surgical guide fits upon the top, the top being contoured to receive and support the dental implant surgical guide.

Disclosed herein is a method of supporting implant surgery in a server, which includes obtaining a subject's oral CT image scanned with a guide model inserted into an oral cavity of the subject, the guide model being manufactured to a certain standard to group human teeth in any range so that the teeth belong to at least one group and to cover a tooth position of a corresponding group, the guide model including a marker made of a radiopaque or radiation semipermeable material, loading a library as information about the standard of the guide model, identifying the marker in the oral CT image, and generating a library matching CT image by matching the oral CT image with the library based on the marker included in the library and the marker identified in the oral CT image, and planning implant surgery of the subject using the library matching CT image.

The invention is directed to a new dental implant and associated parts that allow for insertion in narrow areas of the alveolar bone. Characteristics of the body of the implant allow for comfortable insertion in narrow bone clefts provided by its smooth narrow sections. The implant provides an alternative to complex and time consuming surgical processes involving bone regeneration and/or grafting.

Provided is a guide pin for dental implant surgery, providing guidance so that a practitioner easily determines a location and angle of an alveolar bone of a patient when forming an implant hole in the alveolar bone to place an implant in the alveolar bone. By using the guide pin for dental implant surgery according to the inventive concept, a practitioner may perform the surgery by determining an accurate location and shape of the alveolar bone of the patient when drilling an implant hole in the alveolar bone, and thus, the success rate of the implant surgery may be increased.

A dental prosthesis and a process for design and manufacturing, incorporating an overdenture and a dental implant framework that will be designed and manufactured simultaneously.
