A dental surgical drill guide assembly and method includes a surgical guide housing and a base frame that fits to both gum tissue and one or multiple small areas of jawbone. The apparatus may be configured to accurately place dental implants according to planned positions. Such apparatus may increase the stability of the surgical guide by clasping and/or contacting the jawbone, while improving the overall fit and minimizing the need of invasive surgery and flapping by also clasping and/or contacting selected areas of the gum tissue at the same time. Self-locking alignment members aid in easy removal, and re-installation, of the surgical guide housing to the base frame.

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.

An endodontic file (10) has a handle (11) and a spiral cord (15) of helically wound metallic wire wound in a predetermined direction around a central metallic cord (13) formed between opposite ends of the central cord so as to form an integrated structure (18) of generally conical cross-section including a narrow tip end (17) and an opposite wider upper end (16) supported at the upper end by the handle. A flexible conical reinforcement (26, 31) supported by the handle covers an outermost layer of an upper portion of the spiral cord remote from the tip end, its lower end being of sufficiently low diameter to enter the root canal and dimensioned at its upper end to limit bending of the upper portion. An outer surface (20) of the spiral cord is configured for removing material from inside the root canal when the endodontic file is rotated in the predetermined direction.

Disclosed is a dental implant insertion set including a crown; a fixture which has a hex hole formed therein and of which an insertion angle is set so that the hex hole is aligned corresponding to an arrangement angle of the crown; a guide stent including a stent body formed with a profile set through the three-dimensional procedure guide image to be fixed while covering the periodontal tissue; and an abutment having a hex protrusion formed at a lower portion thereof to be matched with and fixed into the hex hole, such that the crown is aligned and fixed.

A drill guide device for dental implant has a positioning unit and a guiding unit. The positioning unit has a rod, a twist knob and a base. The twist knob has a first indexing table and at least two graduated markings of elevation angle. The base has a second indexing table matching the first indexing table. The twist knob is mounted in the base. The guiding unit has an inner guider and a middle guider. The inner guider has a first bending portion and two first abutting panels, and an inner diameter of the first bending portion corresponds to an outer diameter of the rod. The middle guider has a second bending portion and two second abutting panels respectively attached to the first abutting panels, and an inner diameter of the second bending portion corresponds to an outer diameter of the first bending portion.

A drill guide employs multiple layers of materials with different mechanical properties in order to achieve concurrent goals of rigidity, fit and retention. For example, a rigid exterior shell and a soft interior may be used together to securely and precisely fit a drill guide to a surgical site.

Systems and methods including expandable dental appliances. The expandable dental appliances may include left and right portions that are distinct and separate parts, and that may be coupled by a sliding expansion feature configured to laterally translate the left and right portions toward or away from each other. Each of the left and right portions may include a palatal region and a tooth engagement region that are customized to respective left and right sides of a patient's upper dental arch. Systems may include multiple non-expandable dental appliances that are configured to be worn sequentially over the patient's upper dental arch to expand the patient's palate over corresponding stages of a treatment plan.

Disclosed are an implant surgery planning method using automatic placement of an implant structure, a user interface providing method therefor, and a teeth image processing device therefor. One embodiment provides an implant surgery planning method using automatic placement of an implant structure, a user interface providing method therefor, and a teeth image processing device therefor, wherein during planning, placement of an implant structure is automatically performed with respect to all missing-tooth areas as well as a single missing-tooth area in a teeth image, and placement of an implant structure is automatically performed on the basis of information on relation with a surrounding structure of the missing-tooth area, whereby the present invention increases a user's convenience.

A dental appliances and orthodontic appliance systems for accommodating dental implants. The dental appliances may include an offset portion that is configured to provide a space between the offset portion and an implant implanted within a patient's oral cavity or the patient's tissue surrounding the implant, thereby avoiding impingement of the dental appliance on the implant or the patient's tissue surrounding the implant. Dental implants may include, for example, abutments or caps. The dental appliances may be configured to reposition one or more teeth of the patient.

A computer-based surgical planning system determines locations of surgical instruments or implants relative to a coordinate system determined for a 2D or 3D model of at least a portion of a patient's anatomy. The planning system generates data, such as files or objects, from which holograms of the surgical instruments may be generated by a Mixed Reality (MR) or Augmented Reality (AR) device. The MR/AR device registers the patient's anatomy and anchors the holograms to the patient's anatomy relative to the coordinate system determined for the 2D or 3D model. The holograms include holograms of trajectories of screws for securing an implant to the patient's anatomy.
