Abstract: Molds for fabrication of custom and potentially modifiable abutments and impression posts for dental implants with various degrees of angulations (including zero degrees) and various dimensions are provided, with a generally oval shape that expands laterally upwards, a symmetrical or asymmetrical cross-section, and regular surfaces, that are fabricated as one piece, or as two coupling pieces snapping onto each other. Custom abutments achieve the development of a custom gingival emergence profile, three dimensionally, which is potentially modifiable according to the needs of each particular clinical case. Custom impression posts that correspond in dimensions and angulations to the abutments allow the accurate recording and transfer of the developed gingival emergence profile from the mouth onto the working cast, where the final implant prosthesis is fabricated.

Abstract: A dental instrument is designed to help facilitate the procedure of root canal therapy and can reduce the inaccuracies that are accompanied with using traditional methods of attaching an electronic apex location (EAL) to an endodontic hand file. The endodontic hand file can include an exposed window in the handle of the file that holds an extension of the main body of the file. The clasp from the EAL can attach to this exposed metal in the window of the handle. This new location for attaching the EAL to the hand file can provide an accurate measurement while removing variables such as file movement in the canal, stopper thickness, clearance from the opposing tooth. The endodontic hand file with its exposed window provides a safe, reliable and accurate way of using an EAL to measure the root canal length.

Each of the at least two arm portions are configured to abut tissue. An actuation member is received in the actuation cavity. The actuation member is moveable to vary a distance between the at least two arm portions at the distal end.

Abstract: A method for forming a surgical guide for a dental patient rotates material about a rotation axis to a first angular position and drills a drill guiding hole using a drilling tool having a drilling tool axis. The drill guiding hole is centered about a guide axis that is orthogonal to the rotation axis. A first planar surface of the guide is formed from the material, wherein the first surface is. oblique to the guide axis. The material is repositioned to orient the first surface orthogonal to the drilling tool. A hole pattern is formed having two or more positioning holes in the first surface, with the pattern corresponding to a pin pattern in a tray that is positionally registered to a dental arch of the patient. A second planar surface of the surgical guide is formed, parallel to the first planar surface.
