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 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.

A dental instrument with arms pivotally connected for scissors pivot action between closed and open positions is disclosed. A pair of tines extends from distal ends of the arms and at least one shaping surface on one of said tines is supported so that it is operable to shape an interior surface of one of two matrix bands positioned around adjacent teeth. In use, each tine is positioned inside of adjacent matrix bands positioned around adjacent teeth. As the arms are pivoted towards the closed position, the shaping surface is moved towards the tine on which it is not supported and a clamping force is applied by the tines causing the shaping surface to shape at least one of the matrix bands.
