A bite block with inclined surfaces fits between a patient's upper and lower jaws to hold them apart and fixes the bite block position relative to the jaws. A support plate slides relative to the bite block to position a needle guide on the support plate along an axis of the support plate. A position stop on the support plate contacts the anterior border of the Ramus of the patient's mandible to position the needle guide along the axis. A syringe needle is guided by the needle guide to a predetermined location to administer anesthetic, preferably to the inferior alveolar nerve as it enters the mandible. The needle guide is inclined to avoid gaging and a tongue depressor attached to the support plate positions the patient's tongue.

Apparatuses, components, devices, methods, and systems for generating motion-based dental splints are provided. An example dental splint includes a thin-shell aligner and a contact surface formed based on motion data. The motion data may include relative motion data based on movement of a patients upper dentition with respect to the patients lower dentition. The contact surface may include one or more ridges corresponding to the positions of a contact region on the opposing dentition as a jaw movement is performed. The dental splint may be used to treat temporomandibular joint disorder. An example method includes acquiring an impression of a patients dentition; acquiring jaw motion data for the patient; generating a thin-shell appliance for the patient based on the impression; generating a contact surface based on the motion data; and joining the contact surface with the thin-shell appliance.

A maxillofacial fixation implant having a registration member positioned so as to abut, surround and/or engage with the anterior nares and the anterior nasal spine of a human skull, and the method of designing, manufacturing and utilizing the implant, wherein the implant has an upper anchor implant portion adapted for affixation to the upper portion of a maxilla and a lower anchor implant portion adapted for affixation to separated bone segments of the maxilla.

A three-dimensional device is fabricated in a layer-by-layer approach using a support material. The support material is deposited in a liquid form on a surface, hardened by cooling or ultraviolet (UV) curing, and selectively ablated to create an area within which the desired structure of the device will be formed. Active material is deposited into this area, and the layer-by-layer process repeated until the three-dimensional device has been completed. Thereafter, any remaining support material is removed by water or other solvent.

A splint for releasably fixing a maxillary jaw and a mandibular jaw of a patient together during orthognathic surgery. The splint may include a locking mechanism including a lower section and an upper section. The lower section may be attached fixedly to the mandibular jaw. The lower section may include a horizontal locking pin moveable along a horizontal axis. The upper section may include a vertical locking key attached fixedly to the maxillary jaw. The vertical locking key may include a horizontal pin receiving hole provided along a diameter of the vertical locking key. The horizontal pin receiving hole may be configured to receive the horizontal locking pin. The maxillary jaw and the mandibular jaw may be fixed together responsive to the horizontal pin receiving hole is aligned with the horizontal axis and the horizontal locking pin is inserted into the horizontal pin receiving hole.

A method of implementing a splint device, and associated splint device, are provided for a guidance system of a surgical robot. A splint body includes first and second stabilizing portions extending from opposed lateral sides of a medial portion, and defines a U channel. The medial portion, or the medial portion and one of the stabilizing portions, defines a bridge portion extending along the U channel. A partition member, received by the bridge portion, extends into and longitudinally along the U channel. An adhesive material is engaged with the splint body, within the U channel. The U channel is engaged about a tooth or jaw of a patient, and urged toward the tooth or jaw, such that the partition member engages the tooth or jaw and separates the adhesive material into a first portion engaged with the first stabilizing portion and a second portion engaged with the second stabilizing portion.

A technique for fabricating a surgical splint for use in correcting a dental condition of a patient. The technique involves obtaining a three-dimensional digital model of lower and upper arch dentitions of the patient having the dental condition. Relative positions of the lower and upper arch dentitions are adjusted with respect to each other in the three-dimensional digital model using a computing device. An electronic model of a splint is generated based on the adjusted relative positions of the lower and upper arch dentitions. A splint is then generated in a physical form from the electronic model of the splint.

A bite block with inclined surfaces fits between a patient’s upper and lower jaws to hold them apart and fixes the bite block position relative to the jaws. A support plate slides relative to the bite block to position a needle guide on the support plate along an axis of the support plate. A position stop on the support plate contacts the anterior border of the Ramus of the patient’s mandible to position the needle guide along the axis. A syringe needle is guided by the needle guide to a predetermined location to administer anesthetic, preferably to the inferior alveolar nerve as it enters the mandible. The needle guide is inclined to avoid gaging and a tongue depressor attached to the support plate positions the patient’s tongue.

Integrated support devices for providing temporary primary stability to a dental prosthesis implant, each individually designed and manufactured for a specific pre-identify patient are also provided. An integrated support device can include a prosthesis interface member configured to connect to an abutment or reduced sized portion of a dental prosthesis/implant. The integrated support device also includes one or more bonding wings for connecting to the adjacent healthy teeth.

A bonded retainer configured to stabilize a plurality of teeth in a jaw, the bonded retainer including a contact surface that is aligned overall with a parabolic curvature of the jaw in a longitudinal direction of the bonded retainer and that is aligned locally with a lingual surface contour of the teeth; a lingual surface that extends lingually in parallel with the contact surface, and retentions that extend from the lingual surface transversal to the longitudinal direction.
