Abstract: The present dental implant comprises a hollow perforate trans-mandibular or -maxillary bolt, adapted for receiving a trephined core of bone, for transverse implantation in the maxilla or mandible in conjunction with contiguous straps. These contiguous straps tighten against the periosteum, encase the alveolar ridge and thread through an adjustable implant receptor having a receptor site for abutment thereon. As a result of the combined hollow bolt/strap structure, the dental implant achieves stability by means of (1) medullary bony union with the perforate bolt; (2) subperiosteal bony union with the perforate contiguous straps; and (3) mechanical union afforded by the alveolar-ridge-encasing structure defined by the bolt and contiguous straps. The dental implant thus positioned can be used to support teeth, partial dentures or an entire dental arch. Implant materials may be those known in the art but are preferably biologically inert stainless steel and/or titanium alloys.

Abstract: In dental surgery when a tooth is to be crowned, the tooth has to be prepared by cutting a taper. It has been found that for the successful mounting of a crown the taper must be much more exactly prepared than is possible using currently available equipment. The present invention allows the initial position of the axis of a cutter to be related by means of electronic "spirit levels" to a selected axis. Deviation from this axis by more than a predetermined amount is indicated by light sources which can be seen regardless of the position of a handpiece holding the cutter. By means of a code these light sources indicate how the dentist must move the cutter to return to the correct axis.
