In one embodiment, the invention is a disposable or reusable punch with a handle on one end, and a shank with a roughly cylindrical hollow punch with a circular cutting edge, usually around 1-6 mm in diameter, and often around 2-3 mm in diameter. Unlike prior art punches, however, the invention is configured to additionally make a number of precisely defined linear incisions in the gum tissue during the punching process. As a result, after the underlying jaw bone is exposed by the action of the device, the gum tissue lining the walls of the exposed hole now have enhanced mobility due to the presence of multiple short incisions radiating away from the sides of the gum hole. | 08-05-2010 |
20110059419 | GINGIVA INCISING DEVICE - To easily incise a gingiva particularly at a tongue side and a lip side of a jawbone formed as a bank shape, a gingiva incising device has a cylinder portion, which is longer than a thickness of a gingiva and has approximately the same diameter as a diameter of a dental implant fixture, at a leading end side of a main body portion having a grip portion at a rear end side, and has a cutting blade portion for incising the gingiva formed on a whole periphery of the leading end of the cylinder portion, and the cutting blade portion has a portion which protrudes gradually from a position closest to the grip portion toward a position away from the grip portion. | 03-10-2011 |
20110136075 | DENTAL INSTRUMENT FOR CUTTING SOFT TISSUE - Disclosed is a dental instrument for cutting soft tissue. The dental instrument for cutting soft tissue according to the present invention includes: a main body having an inlet portion for inserting soft tissue to be cut into the main body; a cutter blade arranged in the main body such that at least a part of the cutter blade is exposed outwardly through the inlet portion; and a lid for covering the upper portion of the main body. The cutter blade includes a first cutter blade having a first cut depth, and a second cutter blade arranged in the vicinity of the first cutter blade, and which has a second cut depth shallower than the first cut depth. The dental instrument of the present invention makes it possible to cut the soft tissue in the deep part of a mouth in an easy and simple process, thereby improving the convenience of soft tissue implantation. | 06-09-2011 |
20120064484 | INFERIOR ALVEOLAR NERVE (IAN) PROTECTOR INSTRUMENT - The various embodiments of the present invention provide an inferior alveolar nerve (IAN) protector instrument for proper protection of neurovascular bundle and to prevent the traumatic injuries during oral and maxillofacial surgeries. The IAN protector instrument made of stainless steel has a shank, a blade and a handle. The shank is formed to serve as a soft tissue flap retractor while supporting the blade. The handle is designed with a finger rest for more control and in the pear shape for palm grasp. The shank is bent twice at 120 degrees. The blade is curved with a radius of curvature equal to ⅙-⅛ of a complete circle. The dissecting edge and both lateral line angles are rounded to avoid untoward cutting. The instrument is designed separately for right and left sides of the mouth. | 03-15-2012 |
20120115104 | MULTI-ROOTED TOOTH EXTRACTION DEVICE - A multi-rooted tooth extraction device can include a cutting tool that can be inserted between the roots of a tooth to be extracted. A bracing tool can be coupled to the cutting tool to brace against the crown and a pressure can be applied such that the tooth can be cut from the root to the crown. The separate pieces of the tooth can then be easily removed. The ability of the bracing tool to be decoupled from the cutting tool can allow for improved leverage and usability of the cutting tool while being inserted between the roots. | 05-10-2012 |

20100119991 | TOOTH ROOT TIP EXTRACTOR AND METHOD - An extraction device and method for extracting some or all of a tooth from a patient, such as the root of the tooth, are disclosed. One embodiment of the device includes an extraction burr having helical structure with a positive slope transition portion, and in that manner is distinguishable from a common screw. The helical structure may be configured and shaped such that there is little frictional force placed on the burr as it enters into a tooth. Once the burr enters the tooth the configuration and shape of the burr may provide for increased friction between the tooth structure and the burr, thereby causing the burr to grip the tooth structure and maintain the burr as he tooth is extracted. The extraction burr may include a partial-spiral flute or groove formed in a tip thereof. A lockable and releasable hand piece for attaching to the extraction burr provides leverage to the user for dislodging the tooth root, and is adjustable in at least three different indexable positions in its attachment position with respect to the extraction burr. | 05-13-2010 |
