Method of forming an abutment post

Abstract: Abutment posts, gingival collars, and universal adaptors along with their fixation screws that are used for insertion into dental implants are revealed. The adaptor is universal in that it matches to many different shaped, sized, and styled implants, and standardizes their restoration with uniform gingival collars and abutment posts. A gingival collar of varying sizes, which extends from the top of the flange of the adaptor to the height of the gingival tissue, is used to bring the restoration of the implant into the oral cavity. A post becomes connected to the gingival collar to create a restoration for the placement of a crown or coping over the implant. The top of the adaptor has a projection which is indexed and the top of the gingival collar is also indexed. This indexing allows specific angle correction in the horizontal plane by the counter rotation of the gingival collar and the post head. The post head, itself, comes in a variety of angles and shapes to make vertical angle correction to compensate for angled implant placement. The combination of horizontal correction from the counter rotations of the gingival collar and the post head, along with the vertical angle correction of the post, allows for overall precise angle correction of implant placement.

Method and apparatus for short radius drilling of curved boreholes

Abstract: A method and apparatus for the drilling of the curved borehole portion of a horizontal or directional well. A tight radius of curvature is rotary drilled by use of flexible composite drilling pipe or other flexible pipe common to the industry which terminate within an eccentric collar on the final drill string section. The eccentric collar is equipped with a retractable and grooved compression pad which expands outwardly to hold the eccentric collar (which is also grooved on its opposite side) against the side of the well bore to prevent the eccentric collar from rotating during the rotary drilling process. The final drill string section connects to a lower drill bit collar and rotary drill bit through a driving ball and socket connection. The eccentric collar on the final drill string section that engages the well bore forces the deflection of the drill bit about the ball and socket connection and holds this orientation as the rotating drill proceeds forward. Such a technique can achieve a radius of curvature of less than twenty feet.
