42 Abutment devices and methods for natural teeth US13021616 2011-02-04 US09168111B2 2015-10-27 Young Seo; Jianhua Yang; Victor Chechelski; Jong Gil Park
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.
43 Oral appliance activation devices and methods US13021603 2011-02-04 US08491303B2 2013-07-23 Young Seo; Jianhua Yang; Victor Chechelski; Jong Gil Park
Oral appliance activation devices and methods which are used to facilitate the securement, 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 to an anchoring implant bored into the bones within the mouth. The abutment assembly has a projecting abutment portion with one or more shape memory alloy elements extending along the projecting abutment portion. Energy may be applied to the elements via the activation devices directly over or adjacent to the oral appliance to actuate the elements and thereby either secure or loosen the oral appliance relative to the abutment.
44 Magnetically implantable prosthetic device and method to shorten healing time, enhance bone fusion, and retard bacterial growth US12216261 2008-07-02 US08475167B2 2013-07-02 Frederic B. Dunn
A prosthetic implant is provided that has an implantable magnetic base structure that supports or couples with a prosthetic superstructure for implantation in a mammal. The implantable base more quickly fuses with surrounding tissue or bone with the aid of a magnetic field. The superstructure abuts and is supported by the implantable base, and each comprises a biocompatible magnetic material to establish a magnetic field in the region of the tissue surrounding the implantable base. An anchoring arrangement may be employed to fasten the superstructure to the base. Together, the magnetic base, superstructure, and/or anchoring arrangement are positioned relative to each other to concentrate a magnetic field in the region of the implant to facilitate fusion of the base structure with surrounding bone or tissue. Advantageously, the magnetic field shortens the healing time and retards bacterial growth to quickly fuse the base structure with the surrounding bone or tissue.

54 Dental attachment US702491 1996-08-27 US5931676A 1999-08-03 Yoshinobu Honkura; Takashi Yokoyama; Hideki Fujii; Yoshinobu Tanaka
A dental magnetic attachment, which is embedded in the denture base so as to face a soft magnetic keeper 103 and attract the keeper by magnetic force, comprising at least three yokes which are plates and made of soft magnetic material, and at least two pieces of magnet which have the magnetization direction parallel to the thickness. In the example the attachment comprises a central yoke 10, the magnet 1, the magnet 2, the outer yoke 11, and the outer yoke 12. The invention is characterized by a magnet arrangement in which like poles of the magnet 1 and the magnet 2 faces each other. Because of it mutually independent two magnetic circuits are formed and they offer strong attractive force which is two times larger than that of existing ones in a compact volume required for dental attachment. Furthermore, corrosion resistance and wear resistance are improved by covering the attracting face of the magnet 1, 2 with spacers made of non-magnetic material and covering the whole attachment with the cap made of non-magnetic material except the attracting face of the attachment.
55 Subperiosteal bone anchor US679338 1996-07-11 US5769630A 1998-06-23 Joan M. Hoffman; Michael S. Block
A subperiosteal bone anchor used in two distinct applications; as an orthodontic anchor system, and as an orthopedic anchor system. As an orthodontic anchor system, it is used for treatment of growth disharmony and malalignment of the teeth in which the subperiosteal bone anchor is surgically placed in the subperiosteal tunnel on skeletal bone allowing osseointegration between the subperiosteal bone anchor bone interface and the bone. After osseointegration a palatal bar or palatal wire is attached to the orthodontic anchor system and attached to bands around one or more teeth, holding them immobile. As an orthopedic anchor system the subperiosteal bone anchor is used to stabilize devices which need to be anchored to a bone, or to transmit attractive or distractive forces to a bone for reconstruction or transformation.
56 Magnet element for a dental prosthesis US493874 1990-03-15 US5123843A 1992-06-23 Joseph M. Van der Zel; Daniel Hamerling
A magnet element for a dental prosthesis having a contact surface; a permanent magnet having a first magnet end directed to the contact surface and a second magnet end opposite the first magnet end; and a magnet housing comprising a magnetizable first housing section and a non-magnetizable second housing section. The magnet is only in contact with the first housing section along the second magnet end.
57 Dental implant US932616 1986-11-20 US4758160A 1988-07-19 Yahia H. Ismail
A dental implant comprising an endosteal implant, having a bifurcated core therein, adapted for receiving a prosthetic head. The abutting surfaces of the endosteal implant and the prosthetic head preferably have equal outer diameters. The prosthetic head has a bifurcated shank thereon. The bifurcated core and bifurcated shank cooperate to secure the prosthetic head to the endosteal implant only at an inner segment of the bifurcated core, so as to preserve an annular space between the outer shank segment and the outer portion of the bifurcated core in the area of the alveolar bone. By means of this specialized attachment of the prosthetic head to the endosteal implant, stresses applied to the prosthetic head are translated directly to an inner segment of the endosteal implant, and thus are not applied to the alveolar ridge. Cratering of the alveolar bone is minimized as a result.
58 Magnetic prosthetic element US911871 1978-06-02 US4203216A 1980-05-20 Jean-Antoine E. Deguemp
A magnetic device for retaining a dental prosthesis on a jawbone. Magnetic material is solidly fastened in a support adjustably movable in a frame rigidly fixed to the prosthesis for interacting with magnetic material seated in a cavity in the jawbone. A threaded eccentric gear and a rack cooperate with pinions accessible from outside the frame, for respectively adjusting the relative positions of the magnetic materials axially and laterally.
