A dental implant for supporting periodontal tissue and the supporting bone is provided. The dental implant includes an implant member with inner canal for insertion into a periodontal bone socket, and an anchoring assembly. The anchoring assembly includes a first fastening element and radially equidistant cylindrical members. The first fastening element engages the implant member within the hollow axial cavity. The root section includes through-holes for radially and forcibly sliding the cylindrical members through them. When the first fastening element apically advances within the hollow axial cavity, the cylindrical members generate an anchoring force to anchor the dental implant.

A handheld vise for dental crowns includes a vise block, an elongated handle extending from the vise block, a linear screw embedded in the vise block, and first and second jaws. The second jaw may be arcuate on a gripping surface thereof to conform to the shape of a dental crown. The handheld vise is sized for quickly and readily securing a dental crown such as a stainless-steel dental crown for use in pediatric dentistry. An elastomeric material may be used on the gripping surfaces of the vise. A radius of curvature of the gripping surface of the second jaw may be between about 25-35 mm. A height of the jaws may be between about 2-5 mm, and a distance between the first jaw and a vertex of the second jaw may range from about 3-10 mm. A method and kit for forming crowns including the handheld vise are disclosed.

A dental matrix device positioned between a pair of teeth, the device having a first guide member, a second guide member, and a matrix band. The first guide member configured to be positioned on a first side of the pair of teeth and a second guide member configured to be positioned on a second side of the pair of teeth. The matrix band configured to, in the operable state, extend around at least a portion of the first guide member, between the pair of teeth, and around at least a portion of the second guide member, where the second side of the pair of teeth is opposite the first side of the pair of teeth, and the matrix band is configured to provide a barrier between the teeth during a dental procedure.
