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 device for removing a dental covering having: (a) an engagement portion, having a first plate portion which is substantially flat, that is configured to contact a portion of the dental covering along only one of a facial side or a lingual side of the dental covering; (b) a load applying portion, connected to the engagement portion and having a second plate portion which is substantially flat, which is adapted to rest upon an adjacent surface relative to the dental covering; and (c) an intermediate portion which is integral with and adjacent to both the engagement portion and the load applying portion; and wherein the first plate portion is parallel to the second plate portion. The device may be a dental covering removal tool which may find particular use in removing dental coverings, such as temporary and permanent crowns.

Described herein are systems and methods for extracting a broken fragment of a dental abutment screw from a dental implant. An exemplary system comprises an extractor tool having a tubular outer body and a conductor positioned within the tubular outer body, and an applicator that receives and end of the extractor tool and also includes a heating element that converts electrical energy into heat that is conducted to the extractor tool to melt a thermoplastic adhesive in a cavity at the distal end of the extractor tool, such that the melted thermoplastic adhesive can conform to and engage with a broken fragment of a dental abutment screw within a dental implant when the adhesive cools. The extractor tool can then be rotated to unscrew the broken fragment from the dental implant.

A device for removing a dental covering having: (a) an engagement portion that is configured to contact a portion of the dental covering along only one of a facial side or a lingual side of the dental covering and receive a prying load applied by an operator; and (b) a load applying portion connected to the engagement portion which is adapted to rest upon an adjacent surface relative to the dental covering and be pivoted upwardly or downwardly by application of the prying load. The device may be a dental covering removal tool which may find particular use in removing dental coverings, such as temporary and permanent crowns.

Root canal abutment devices and methods which facilitate the adjustment or removal of an oral appliance, e.g., a crown or bridge, from a reconfigurable abutment assembly are described. The adjustable abutment assembly may be secured within a pulp chamber of a pre-existing tooth. The abutment assembly has a projecting abutment portion with one or more shape memory alloy sleeves or plates or elements extending along the abutment. Each of the sleeves has a length with at least one curved or arcuate portion. Energy may be applied to the elements such that the arcuate portion flattens to allow for the oral appliance to be placed thereupon while removal of the energy allows the elements to reconfigure into its curved configuration thereby locking the oral appliance to the abutment. Removal of the oral appliance may be effected by reapplication of energy to the elements.

Provided herein are handheld dental devices useful in performing a wide variety of dental procedures, including crown removal applications. Related methods of administering dental therapy to patients' are also provided.
