A system of tools for use in an orthodontic setting made up of a series of individual tools. Each tool comprises a pair of flat, generally elongated arms placed in an adjacent lengthwise relationship and connected at each first ends in a manner so as to force the remaining portions of the arms apart. Each of the tools has specially modified features that allow the tools to perform specific functions such as: scraping teeth and orthodontic devices; grasping orthodontic brackets; placing orthodontic brackets onto a tooth without disturbing other free-floating brackets; measuring the distance between portions of a tooth so as to ensure proper bracket placement; measuring the distance between orthodontic brackets; and aseptically retrieving objects from a drawer.

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.

The present invention provides a tweezer for dental and other applications. The tweezer including a main body portion (12, 14) extending in a generally longitudinal direction. The main body portion having a first end (20) and a second end (18). A hinge connector (16) is located between the first end and the second end. A first pair of pincers is located at the first end (20). A second pair of pincers is located at the second end (18). A bias mechanism (22) urges the first pair of pincers (20) into a closed position and urging the second pair of pincers (18) in an open position, whereby the user may apply a force to the tweezers to overcome the bias mechanism (22) and urge the first pair of pincers (20) away from the closed position and the second pair of pincers (18) away from the open position.

The present invention relates to an elastic tongue-dorsum refraction device for treating obstructive sleep apnea / hypopnea syndrome (OSAHS), clamping pliers, installation pliers, a line guide, and an implantation method. The elastic tongue-dorsum refraction device of the present invention includes a tongue dorsum connection mechanism, an elastic retractor and a tooth-side fastener. The tongue dorsum connection mechanism is disposed at the tongue dorsum portion, the tooth-side fastener is fixed to teeth or the alveolar bone or outside the maxilla and mandible lips, one end of the elastic retractor is connected to the tooth-side fastener, and the other end of the elastic retractor is connected to the tongue dorsum connection mechanism. In this way, an elastic retraction device using the tooth-side fastener as a fulcrum is formed. By pulling up the sagging tongue root forward, stenosis and obstruction of the airway at the glossopharyngeal portion are prevented, thereby providing a function of treating snoring and OSAHS. Since the elastic refractor exerts an elastic retraction force on the tongue dorsum portion, the movement of the tongue tip is not affected when the tongue root is properly pulled up, so that a clear language function and an adequate swallowing function can be maintained, and not only the airway at the glossopharyngeal portion is enlarged, but also good comfort is provided. In addition, the present invention further discloses clamping pliers, installation pliers and a line guide for use together with the elastic tongue-dorsum retraction device, and an implantation method of the elastic tongue-dorsum retraction device.

An apparatus for pulling loose teeth having a releasably attachable decorative element for soothing the patient. The apparatus of the present invention provides a first arm and a second arm each with a decorative end and a tool end wherein the first and second arms are connected at the decorative ends. The tool ends of the first and second arms are moveable between a first position, wherein the tool ends of the first and second arms are adapted to disengage the tooth, and a second position, wherein the tool ends of the first and second arms are adapted to engage the tooth. A decorative element is releasably attachable to the decorative end of the first and second arms.

The invention specifically discloses a clamping device for dental implantation, the clamping part includes a first clamping arm and a second clamping arm, and the tails of the first clamping arm and the second clamping arm extend into the clamping part The cavity inside the sleeve is fixed on the fixed base of the clamping part. An annular groove is arranged on the outer wall of the rear end of the sleeve of the clamping part, and an engaging ring is arranged in the annular groove. A plurality of snapping wings are arranged on the outer periphery of the ring, the rear end of the clamping portion sleeve is arranged in the opening at the front end of the adjustable connecting rod, and the snapping wings on the outer periphery of the snapping ring are clipped on the inner wall at the front end of the opening. The clamping sleeve and the adjustable connecting rod are axially fixed through the clamping ring, and the clamping sleeve is disassembled by shrinking the clamping wings on the clamping ring through the square hole on the adjustable connecting rod , its operation is convenient and simple.
