In some embodiments, one or more knots are disposed along a portion of the guiding wire that traverses the wedge component. | 02-23-2012 |
| 20120058447 | INTERDENTAL WEDGE - The invention relates to an interdental wedge for use with a matrix band when preparing a filling on a tooth to be restored and/or for use with a rubber dam, by inserting the interdental wedge into an area near the gingiva between the tooth to be restored or to be treated and an adjacent tooth, with an insertion area having a cross section delimited by a lower face, by an inner face and by an outer face, wherein, in the state inserted near the gingiva, the lower face is directed towards the gum, the inner face is directed towards the tooth to be restored or to be treated, and the outer face is directed towards the adjacent tooth, wherein the inner face and the lower face run together in an edge, which is designed such that, in the state inserted near the gingiva, it bears on the tooth to be restored or to be treated, in order to provide a sealing action against passage of material. | 03-08-2012 |
| 20120164597 | DENTAL WEDGE WITH TOOTH GUARD AND METHOD OF RESTORING A TOOTH USING THE SAME - The present invention relates to dental devices utilized during the restoration of teeth and more particularly a dental wedge, for use in the inter-proximal space between adjacent teeth, the dental wedge comprising: a wedge body; and a guard releasably engaged to the wedge body, wherein the guard is transformable between a first position adjoined the wedge body and a second position disengaged from the wedge body. | 06-28-2012 |
| 20130004914 | DENTAL SEPARATOR APPARATUS AND METHOD - A tooth separator apparatus, according to one embodiment, includes a tong having two arms constructed of a resilient material and having a wedge disposed at each end. An expander member is coupled to the two arms, and a drive shaft is coupled to the expander member. When a user moves or rotates the drive shaft, the expander member is moved into a position which causes the two arms and wedges to separate by a distance sufficient to permit the wedges to be inserted in a patient's mouth and positioned adjacent to two teeth that are to be separated. When the user rotates the drive shaft in the reverse direction, the expander member returns to its original position thereby releasing the separating force on the resilient arms and permitting them and the wedges to move in a closing direction with sufficient force to separate the adjacent teeth. | 01-03-2013 |
| 20130122462 | DENTAL INSTRUMENT - The dental instrument is formed of a single elongate, unitary length of surgical steel or other suitable material. The instrument preferably includes two mutually opposed working end portions and a generally medial cushioned handgrip portion. Each of the end portions has a shallow axial channel and a sharpened distal end having a notch formed therein. The two sides of the notch provide two contact points or areas to avoid the extreme pressures applied by conventional single contact point instruments and the resulting breakage of the tooth and subsequent difficulty in extracting the base or root of the tooth that often occurs. A lateral notch having sharpened edges is also preferably formed along one side of each working end portion of the tool. The configuration of the dental instrument provides greater versatility to perform the manipulations generally required for tooth extraction. | 05-16-2013 |
| 20130149665 | DENTAL WEDGE WITH COATNG - A non-porous dental wedge having a surface coating of a material for aiding a dental procedure. A thin coating of an adhesive and particles having a particle size less than 200 microns is placed on the surface of the non-porous dental wedge. The material is preferable an astringent. The non-porous dental wedge is resistant to compression and the thin surface coating with small material particle size facilitates rapidly disperses the material during a dental procedure. | 06-13-2013 |
| 20140120497 | DENTAL SEPARATOR APPARATUS AND METHOD - A tooth separator apparatus, according to one embodiment, includes a tong having two resilient arms that are biased in an open position and having a wedge at each end of each arm. A drive shaft moves a compression member to overcome the resiliency of the arms and move them and the wedges in a closing direction for separating the teeth. The drive shaft can also move the compression member in the opposite direction to release the closing force on the arms and thereby permit their resiliency to allow them and the wedges to move to an open position. | 05-01-2014 |
