The clips and methods of the present invention may be used, for example and without limitation, for repairing tears and other defects endoscopically.

A pliers for forming orthodontic wires has opposing beaks with complementary wire-forming surfaces that include interfering portions. A hinge mechanism enables the beaks to open and close by rotating about an axis, and also allows a range of axial motion between the beaks sufficient to prevent interference between the wire-forming surfaces as the beaks are closed. By preventing such interference, novel over-bending capabilities can be achieved to form useful bending of low spring rate wire. A spring, such as a Belleville washer, exerts a biasing force parallel to the hinge axis to maintain alignment of the beaks, but allows the required range of axial motion between the beaks to prevent interference.

A dental pliers appliance and associated method for removing teeth from a patient's gum line and bone. First and second pivotally connected handles are provided, each including a user grasping portion. The first handle terminates in an arcuately extending jaw exhibiting a substantially pointed end, the second handle terminates in an opposing and offset support exhibiting a support surface with an ergonomic configuration substantially matching that of the patient's gum line. Upon aligning the support along a selected location below the gum line, and further aligning the jaw in abutting fashion against an inwardly facing side of a tooth, the offset support defining a center point of rotation proximate to an edge location of the gum line and bone. The handles are subsequently rotated in an outward fashion away from the patient's gum line to forcibly dislodge the tooth from the patient's gum line and bone.

A method for fabricating a custom surgical stent. A human third molar tooth bud ablation system for use in a tooth bud ablation procedure that results in tooth agenesis. A tooth bud ablation procedure that results in tooth agenesis. These methods, systems, and procedures may include and / or use ablation probe tips and / or stents.

A device for inserting a threaded dental implant (I) in a patients jawbone as well as for loosening and removing a threaded dental implant (I) mounted and possibly osseointegrated in the alveolus jaw-bone of a patient. An ultrasonic vibration actuator, e.g. a piezoelectric transducer, generates ultrasonic vibrations with a frequency within the range 20-50 kHz, preferably within 24-36 kHz, and preferably in a direction around the longitudinal axis of the dental implant (I). The actuator, being a handpiece (H) structurally connected with a handpiece head (HD). A fitting-means (F), e.g. a socket, is positioned in the head (HD) of the handpiece (H), the head (HD) being arranged for entering the patient's mouth. The fitting-means (F) is shaped to provide a rigid engagement directly with the dental implant (II, I2) or indirectly by an adaptor (AD1, AD2) being rigidly tightened on top of the dental implant (II, I2) platform. The fitting-means (F) thus transmits ultrasonic vibrations to the dental implant (II, I2) for either inserting a dental implant or alternatively loosening the dental implant from the jaw bone.

A powered surgical instrument is provided. In some embodiments, the powered surgical instrument may include a housing; a receiver, at least a portion of the receiver is movably received within the housing, a distal end portion of the receiver being configured to receive an expander adapted to expand a tooth socket within a treatment area, wherein the receiver is configured to move between a first receiver position and a second receiver position; a bias assembly operatively connected to the receiver and configured to urge the receiver towards the second receiver position; and an actuator disposed within the housing and configured to move the receiver at least from the first receiver position to the second receiver position, wherein the receiver is configured to be selectively moved between the first and second receiver positions independent of the actuator.

Ablation probe tips (108, 148, 320, 360) and physical and virtual stents (110) for use in tooth bud ablation procedures that result in tooth agenesis as well as tooth bud ablation methods are described herein.

A tooth extraction device is provided that uses a clamp assembly to clamp a tooth to be extracted, and a handle for positioning the clamp assembly within a patient's mouth. A cable and an actuator for moving the cable are provided for moving the clamp assembly. The clamp assembly includes a pair of clamp links pivotally connected to a carrier block. The carrier block is slidably movable relative to the handle to extract the tooth after the clamp links are rotated into engagement with opposite sides of the tooth. A base tooth support engages a first neighboring tooth on a proximal side of the clamp assembly, and a removable tooth support engages a second neighboring tooth on a distal side of the clamp assembly. The tooth supports distribute the force of extracting a tooth over the neighboring teeth, thereby allowing more control in manipulating the device during a tooth extraction.

An apparatus to assist in the dislodging of an intraoral device. The apparatus comprises an elongate body having a central portion, a first distal portion having a first terminal end and an opposing second distal portion having a second terminal end. The first terminal end further comprises an outwardly depending lip and the second terminal end comprises an arcuate projection. The lip is used to exert a mechanical force on an affixed intraoral device to assist in dislodging the device. The arcuate projection is inserted in between the intraoral device and the tooth to assist in dislodging the device.

A flush cutter of wires located on a patient's teeth has at least one pivotably carried cutting edge. An outer surface of the edge can be positioned adjacent to a surface from which the wire protrudes. An elastic insert or clamp, for griping cut wire ends, is carried adjacent to the edge. The insert has first and second spaced apart ends. A rigid surface is located to pivot toward the edge. The elastic clamp extends, in part, to the inner surface of the edge. As the cutting edge moves toward the rigid surface to cut the wire, the elastic clamp grips the cutoff wire end for removal. The rigid surface can be formed as a second cutting edge that moves toward the one cutting edge.

A dental wrench device to loosen and extract teeth, comprising a handle with a fixed tapered jaw. A moveable jaw is also coupled to the handle. The tapered jaw is positioned along the root of a tooth selected to be extracted. The moveable jaw has a blunt contoured shape configured to grasp the gum and bone on the opposite side of the selected tooth at a level below the crown of the tooth. The device is applied and tightened around the selected tooth by turning a thumbscrew, or other jaw movement interface, that moves the moveable jaw end closer to the fixed tapered jaw end until the tooth is tightly gripped by the device. Once the wrench is locked into position, force may then be applied to extract the tooth. The device may also incorporate an optional force feedback gauge to warn the operator when excessive force is being applied.

A dental instrument includes a first arm, a second arm, which is pivotally coupled to the first arm about a pivot axis, and a spring. The first and second arms are pivotal with respect to each other in a plane generally orthogonal to the pivot axis. Each of the arms has a proximal portion, a medial portion, and a distal portion, with the proximal portions defining hand grip portions, and with the arms being pivotally connected at their medial portions. The spring biases the distal portions of the arms toward each other. Each of the distal portions comprises a first portion and a prong portion depending from the first portion. The prong portions comprise back-to-back generally C-shaped portions and spaced apart tines. The C-shaped portions define a pair of seats, with the tines depending from the seats and having spaced apart distal ends adapted for engaging a rubber-dam clamp, and the seats providing contacts for a dental retaining ring.
